Making sure a concrete floor screed is durable is essential for long-term performance when it comes to protection. For any outdoor space, such as a patio or driveway, the concrete screed requires protection from the weather. This is selecting the appropriate materials and adhering to a detailed process in order to properly strengthen and seal the surface.
Choosing premium materials intended for outdoor use is the first step towards strengthening a concrete floor screed outdoors. This usually entails using a robust concrete mixture that is impervious to deterioration and fracture. It is also possible to add reinforcement materials, like fiberglass or wire mesh, to improve structural integrity and stop cracks from developing over time.
It’s crucial to properly prepare the concrete surface before beginning the protection process. This entails clearing away any dirt, oil, or debris that might compromise the protective layers’ ability to adhere. To ensure a smooth and even base, any existing cracks should be fixed with an appropriate concrete patching compound.
Applying a concrete sealer or waterproofing agent is the next step after the surface has been cleaned and prepared. These goods are designed to get into the pores in concrete and form a barrier that keeps out moisture, UV light, and other elements. Achieving the desired level of protection may require applying multiple coats, depending on the product.
It’s crucial to follow the manufacturer’s instructions and give the sealer enough time to dry and cure. By doing this, you can maximize the durability and weather resistance of the concrete by ensuring that the protective layer adheres to it effectively. Frequent upkeep, like applying sealant again every few years, can help the concrete floor screed last longer and keep its protective qualities.

What it is?
In order to maintain the performance properties of the rough reinforced concrete coating—which is subjected to intense use or harsh environments—a street concrete floor must be strengthened through a repair and restoration process.
Stiffening the screed could require a number of production processes, including:
- impregnation of porous composition;
- arrangement of a thin surface high-strength and elastic layer of another material.
Each of these approaches necessitates strict adherence to the technological map as well as fulfillment of specific requirements and nuances.
When to strengthen?
For any of the following scenarios, strengthening a screed composed of monolithic reinforced concrete or a high-strength cement-sand mixture is necessary:
- Physical wear and tear of the structure from too intense or prolonged use.
- Partial or complete delamination of the structure due to temperature changes or heavy exposure to precipitation.
- Preventive strengthening of the structure when only the top layer is worn.
- The appearance of through cracks on the street floor screed due to brittle destruction of the material structure due to deformation of the coating.
- Abrasion of the top layer, the appearance of potholes, tire marks and other minor defects.
- The screed begins to burn during operation.
- A void is formed under the screed due to subsidence of the soil base, which is located directly under its surface.
- In case a finishing coat layer is required.
- Peeling and destruction of the paint and varnish coating layer, which requires immediate restoration.
- The screed begins to vibrate or crack when loads are applied.
It is advised to perform a coating diagnostics beforehand, test the concrete screed’s strength using non-destructive techniques, ascertain how much its actual physical and mechanical characteristics deviate from the necessary parameters, and decide what steps need to be taken to achieve these indicators, before deciding to strengthen it or choose the material that is best suited for this operation.
Basic protection methods
Professional finishers frequently employ the following fundamental techniques to strengthen the coating, even though there is currently a vast array of materials available on the market for strengthening screeds:
- Ironing of the structure.
- Impregnation with reinforcing polymer compounds.
- Construction of a polymer film with increased strength characteristics.
- Painting with elastic paint and varnish compositions that form an unbreakable film after polymerization.
- Installation of self-leveling self-leveling floor with increased frost resistance grade.
- Application of liquid glass in several layers, impregnating the pores in concrete.
- Installation of coating or adhesive waterproofing with temperature treatment of the structure.
- Installation of a final floor covering over a screed – paving or porcelain tiles, wooden flooring or other types of finishing materials.
- Installation of a duplicate concrete or cement-sand screed with steel or composite mesh reinforcement.
Property owners are advised to research all material properties, including their chemical composition, environmental friendliness, physical characteristics, and mechanical properties, before selecting any of the aforementioned methods. This will help to ensure that the reinforced concrete floor will fully satisfy all operational requirements placed on it, in compliance with the working draft.
How to protect the surface?
The most common ways to carry out this production operation are described below, making it easier to select the one that will strengthen a concrete screed on the street and meet operational requirements.
You must comprehend the technology required to complete the task, as well as the tools and supplies required, and weigh the benefits and drawbacks of each option before making a final choice.
Ironing
It is well known that hydraulic binder, or cement, has exceptional performance qualities that help lower abrasion and greatly extend service life as long as a material with increased strength characteristics is purchased.
Depending on the solution’s consistency and moisture content, you can use cement laitance or dry cement to reinforce it. The designated material is poured or poured onto the screed’s surface after it has been cleaned, and then it is rubbed with a unique plaster trowel.
The structure compacts as a result of fine particles entering each pore. Following application, the material is slightly moistened, the smoothing process is repeated, and the structure acquires its design strength during the polymerization process.
Instruments:
- scissors for opening a bag of cement;
- trowel or scoop for dosing bulk material;
- container for kneading dough or milk;
- mixer for mixing ingredients until smooth;
- plaster float, which is used to smooth the composition after application.
Resources:
- dry high-quality cement grade M400 and higher, or a high-strength composition of the NTs type with minimal shrinkage;
- pure water;
- plasticizers, when carrying out work in the cold season.
Detailed instructions:
- The surface of the screed is cleaned of dust and dirt.
- Cement is diluted with water and additives in a separate container.
- First of all, the composition is applied to cracks, chips and other pronounced defects to eliminate them.
- The concrete screed is pre-moistened with water using a fine spray.
- The mixture is poured onto the surface of the screed, or, in some cases, dry cement is poured directly from the bag.
- The master carefully smoothes the material under pressure, closing every pore on the screed.
- Survives for at least 48 – 96 hours until the composition is completely polymerized, after which the screed can be used in normal mode.
Benefits
- one of the most accessible and cheapest options;
- effective closing of pores, the ability to do the work yourself, since the master does not require professional tools and equipment.
Drawbacks:
- the coating quickly deteriorates after intensive use and often requires restoration;
- the screed often continues to collect dust, and its structural strength practically does not increase, since the reinforcement is carried out only on the surface, the cement remains a brittle and inelastic material.
In the video, we go into detail about ironing:
Waterproofing
Here, we refer to coating or pasting waterproofing, which can be created with the newest polymer rubberized compounds or bituminous materials.
The technological map states that when applied and fixed, the floor is simultaneously protected from moisture or penetration and the concrete screed is strengthened, preventing the formation of through cracks when applying non-design static or dynamic loads.
After the floor has been used outside for a while, high-strength waterproofing can be applied on top of the screed as well as underneath it during construction.
Instruments:
- gas-burner;
- pressure roller, glue dispenser;
- when installing polymer coatings;
- awl for piercing bubbles in bitumen materials;
- a broom for cleaning the screed before applying waterproofing;
- personal protective equipment, as work is often performed at elevated temperatures.
Resources:
- bitumen waterproofing on fiberglass;
- polymer waterproofing with increased adhesion to concrete;
- in some cases – bitumen mastics.
Detailed instructions:
- As in the previous version, the error is burned by dust and dirt.
- Wet screed must be thoroughly dried with burners.
- The plane is treated with bitumen mastic or a penetrating primer.
- When fusing bitumen adhesive waterproofing, the roll is heated as it rolls out using burners until the bitumen begins to melt.
- The roll is gradually rolled out strictly into an even row, without bending or folds.
- The second row must be overlaid with an overlap of at least 100 mm on the first.
- Each overlap is heated to ensure a continuous flow of molten bitumen along the entire length of the joint.
- Polymer waterproofing is attached using epoxy two-component adhesive with anti-frost additives.
- After gluing, it is necessary to iron the entire surface of the floor with a roller press.
- Polymerization of the glue or cooling of the bitumen lasts no more than 1 – 2 hours, after which you can install a final coating or use the floor outdoors.
Benefits
- simultaneous protection against moisture and achieving the highest screed strength;
- additional protection of the structure from freezing, since in the absence of water in the pores of the concrete;
- it does not expand and does not destroy its structure.
Drawbacks:
- impossibility of working in rainy weather;
- high cost of materials;
- the need to heat most types of waterproofing;
- mandatory provision of a fine covering of the screed – paving slabs, self-leveling flooring, duplicating concrete composition, artificial turf;
- impossibility of working in the rain.
Special formulations
Two primary components can be used to create reinforcing materials for outdoor screeds: cement binder with the lowest fraction or elastic polymers that dissolve in water and have enough viscosity to seal pores. Special compositions are polymerized and kept in place until they become stronger after installation. These products are sold to the market in plastic, dry form, or in bulk.
Instruments:
- putty knife;
- Master OK;
- grater;
- mixing container;
- mixer for mixing ingredients;
- scales or volumetric flask for dosing the required amount of dry or dressing substance.
Resources:
- special mixture in bulk;
- granular, liquid or dough-like state;
- water;
- anti-frost or plasticizing additives.
Detailed instructions:
- A penetrating primer is applied to the prepared surface, after thorough cleaning, degreasing and dehydration of the hardened concrete screed.
- In some cases, penetrating waterproofing may also be required.
- The composition is diluted in the required proportions, according to the operating instructions, and then mixed with a mixer until a homogeneous plastic mass without lumps is achieved.
- Next, the same production process is performed as when ironing a concrete screed on the street – the plastic substance is smoothed out and rubbed into the pores on the surface of the concrete with a float.
- The polymerization of the composition is expected – from 24 to 72 hours, depending on the category of the binder component.
Benefits
- simple dilution and application;
- a balanced composition that has all the necessary physical and mechanical characteristics;
- durability and reliability of the finished coating.
Drawbacks:
- the high cost of a bag of dry substance or a canister with special compounds;
- requires careful surface preparation, as well as combined use with various impregnations.
Impregnations
The application of polymer impregnations—waterproofing, primers, penetrating reinforcement, and other recent advances in the chemical industry—to strengthen different types of concrete structures is growing.
Almost all of the pores in concrete are penetrated by liquid compositions, which upon polymerization produce an elastic structure. Certain materials also have the ability to expand after drying, and the elastic consistency keeps the cement binder’s walls intact, creating the impression of injection under pressure.
Instruments:
- rollers, brushes;
- containers for mixing with other components;
- whisks to achieve a uniform consistency of the material;
- cuvettes;
- if necessary, use a hair dryer to quickly dry the substance.
Resources:
- polymer impregnation in liquid, viscous or granular state;
- some materials are also supplied as two-component formulations with hardeners for fast and effective polymerization.
Detailed instructions:
- The screed is examined for defects – cracks, chips, cavities, non-vibrated areas, traces of delamination.
- The entire surface is dusted, dried and completely cleaned of all greasy stains, such as machine oil.
- All major defects are repaired using non-shrink compounds.
- The penetrating mixture is prepared in a separate container, according to the operating instructions.
- The mixture is dosed into a ditch, from where it is transferred to the surface of the concrete screed using a roller.
- The composition polymerizes for 1 to 4 hours, after which the procedure is repeated.
- The number of layers depends on the physical and mechanical characteristics of the liquid impregnation, as well as on the required strength of the finished screed structure.
Benefits
- ease of application;
- fast polymerization;
- complete impermeability of the concrete screed;
- sealing small shrinkage cracks;
- most often, materials are supplied from the factory, ready-made, which eliminates the mistakes of the master when preparing them, since mixing the composition is not required.
Drawbacks:
- impossibility of sealing large cracks;
- chips;
- sinks and other defects resulting from poor-quality screed creation or mechanical damage;
- the difficulty of carrying out work in the cold season or during precipitation.
Liquid glass
Liquid glass is an organic liquid product that is created by diluting potassium and sodium silicates in water and adding polymeric materials and plasticizers.
When dried and polymerized, this alkaline composition can form an unbreakable glassy structure. Additionally, because the liquid does not undergo any processes involving the formation of gases, the structure is uniform and devoid of tiny pores, offering increased strength and protection against screed abrasion.
Instruments:
- cuvette;
- roller;
- brush for cleaning the surface of the screed;
- spatula for repairing large defects;
- brushes for applying makeup in hard-to-reach places.
Resources:
- liquid glass in a canister;
- or in a bottle, depending on the packaging of the material from the manufacturer;
- solvent for degreasing concrete surfaces, cement-based repair mixtures.
Detailed instructions:
- The screed can be completely swept up; it is recommended to use an industrial vacuum cleaner for such purposes.
- If there is moisture in the concrete structure, it is recommended to dry it using a hair dryer or gas burners.
- The material is poured into the cuvette.
- A roller with soft fur is selected and rolled over the entire plane of the cuvette.
- Liquid glass is generously applied to the surface of the screed.
- The material is rolled out onto a concrete structure.
- Wait 2 to 5 minutes for the composition to be absorbed into the pores of the concrete, after which the work is repeated.
- The number of layers depends on the pore size in the concrete screed – when the expected result is achieved, the surface of the concrete screed has a semi-gloss structure with reflections.
- Polymerization of liquid glass does not exceed 1 – 2 hours, after which the screed can be used in operating mode.
Benefits
- a very dense structure, completely devoid of pores, ensuring water resistance and increased frost resistance of the concrete screed;
- high-strength connection of the material components ensuring the reliability and durability of the screed outdoors, even with intensive use.
- one of the main advantages is also the high covering power of the material and low consumption.
Drawbacks:
- the same as in the case of penetrating compounds;
- upon contact with water, the alkaline solution loses most of its physical and mechanical properties;
- high retail cost of liquid glass;
- this material does not hide defects in any way, which requires repair of the surface in the presence of cracks or other damage.
Surface treatment
Along with the street concrete screed strengthening techniques mentioned above, each customer has a variety of polymer or paint coating options to select from, as listed below:
Painting
The quickest and easiest way to reinforce the screed, provided that extra steps are taken to get ready for the installation of penetrating compounds in the porous material.
Instruments:
- paint tray;
- roller with a long handle, measuring flask for dosing the material;
- mixing if necessary;
- rags for removing greasy stains;, broom or vacuum cleaner for dust removal of the screed.
Resources:
- paint with the selected chemical composition;
- solvent, plasticizers.
Detailed instructions:
- The surface of the concrete screed is prepared for painting – the plane is cleaned and dried.
- If necessary, minor repairs are carried out.
- The plane is covered with a primer or concrete contact.
- If necessary, penetrating waterproofing of the screed material is arranged.
- The paint is poured into the tray.
- The first layer of paint is rolled out over the entire plane, in the longitudinal direction, using a roller.
- Corners and hard-to-reach places are painted with brushes.
- It is recommended to apply the second layer in an orthogonal direction, in even stripes, with minimal overlap between them.
- To strengthen the screed outdoors with paints and varnishes, it is recommended to apply 3 to 4 layers, depending on the composition of the paints and the operating conditions of the floor.
- Before applying each layer, it is recommended to wait at least 2 hours until the composition is completely polymerized, which is also required from the conditions of unhindered stepping on the surface of the screed, without the risk of the soles of the master’s shoes sticking.
Benefits: Depending on the material’s chosen shade, this is one of the least expensive ways to reinforce the screed while also strengthening the structure and fixing concrete fragments. It also produces an eye-catching visual effect.
Drawbacks:
- a low strength of the composition is achieved, as a result of which the screed may still be subject to cracking or delamination;
- the need to combine the material with primers and penetrating waterproofing, rapid abrasion of the composition, subject to use in pedestrian areas or internal roadways.
Self-leveling floor
A great way to reinforce a street concrete screed that not only produces a sturdy layer but also makes sure that any surface flaws that are visible to the naked eye are completely leveled.
Instruments:
- container for mixing the composition;
- drill with a mixer attachment to achieve a uniform consistency of the material;
- special toothed roller for applying self-leveling floor in liquid form.
Resources:
- dry or plastic pre-made self-leveling floor;
- water in the required proportions, if necessary – plasticizers and antifreeze additives.
Detailed instructions:
- Also, as in the previous case, the surface of the concrete screed is prepared for application of the substance.
- The dry composition is poured into a tall plastic bucket with a volume of at least 20 liters.
- Water is added to the dry components in the required proportion, as well as active plasticizers, depending on the temperature and expected hardening conditions.
- Along the perimeter of the concrete structure, formwork is fixed to the end faces of the screed with a height of at least 20 – 30 mm above the concrete surface.
- The finished composition is poured onto the surface of the screed.
- Wait 2 to 4 minutes for the liquid substance to spread over the entire plane, after which a new portion is added.
- When the liquid substance has spread over most of the surface of the screed, it is necessary to level it using a toothed plastic roller.
- When the work is completed, it is necessary to completely prevent the ingress of precipitation onto the surface of the self-leveling floor.
- It is recommended to carry out all work on installing a self-leveling floor within 20 – 40 minutes, as the binding components begin to set.
- After application, wait at least 3 days, and, with a thickness of more than 10 mm – from 4 to 7 days.
- After gaining strength, it is allowed to use the floor surface in operating mode.
Benefits
- self-leveling coating quickly hides almost all screed defects;
- when applying, no special devices or equipment are required, since the material spreads across the floor under its own weight;
- after polymerization, an unbreakable, perfectly even layer is formed.
Drawbacks:
- a long period of drying and strengthening of the composition, which is not always convenient in bad weather conditions or when mixing is incorrect;
- the material can develop shrinkage cracks, which will reduce its effectiveness to zero;
- to achieve the expected effect in open space;
- a layer with a thickness of at least 10 mm is required.
Polymer film
One of the most advanced techniques, used not only in pedestrian zones but also in industrial buildings, logistics centers, factory cold warehouses, and other locations with the worst possible flooring conditions.
Instruments:
- paint ditch;
- soft roller;
- brushes with different working widths, brush;
- industrial vacuum cleaner;
- in some cases, a gas burner with a propane cylinder or a powerful construction hair dryer will be required, given that the screed is being strengthened in an open space.
Resources:
- liquid polymer of the selected brand;
- hardener, degreaser;
- concrete cleaner;
- polymer-based impregnation, provided that its chemical composition does not neutralize the effect of the future elastic film.
Detailed instructions:
- The film is applied in molten, chemically liquefied form or finished form if the material is supplied to the site in rolls.
- Before applying the film, it is necessary to sweep the surface of the screed, and also repair all major defects using a non-shrinking mixture.
- The material can be applied ready-made, as a waterproofing membrane, with adhesion using adhesives, or using a high-temperature method.
- If a liquid composition is applied, it dries during polymerization and forms a uniform, unbreakable coating.
- When applying the film, it is recommended to arrange a layer of self-leveling floor with a thickness of 5 mm or more in advance, since this eliminates the risk of damage to the material by sharp parts of the coarse aggregate of the screed.
- Polymerization of adhesive compositions depends on the material and lasts from 30 minutes to 5 – 6 hours.
- When gluing the film, it is very important to exclude any bubbles and delamination, as this will lead to complete destruction of the membrane during operation.
Benefits
- unbreakable elastic and elastic material with a very high coefficient of specific adhesion to the surface of the concrete screed;
- excellent frost resistance and waterproof qualities;
- high hardening speed after application.
Drawbacks:
- high cost of material;
- in case of delamination due to moisture entering a local defect;
- the entire film is completely dismantled;
- difficulty of application due to the need to heat the composition;
- It is recommended to turn to professionals, which affects the cost of the coating installation.
It is advised to purchase paint and varnish mixtures or self-leveling floor components only from reliable, well-known vendors whose goods are in great demand by customers, have been on the market for a considerable amount of time, and have received a lot of favorable feedback on independent Internet forums.
How to choose the best option?
When selecting the optimal solution for fortifying the floor screed, it is advised to consider the following significant details:
- Required strength indicators of the restored structure.
- Climatic conditions in the region where the screed is used.
- Intensity and nature of load application during operation of the screed surface.
- Nature, quantity and depth of mechanical damage.
- Duration of operation of the screed.
- Detailed design requirements, availability of regulatory requirements from the municipality for strengthening the screed.
- The quality of the soil base under the screed.
Therefore, it is advised to use repair compounds or self-leveling floors in the event of significant surface defects. Generally speaking, a duplicate structure needs to be installed if the screed is totally deformed due to operational loads.
It is sufficient to use penetrating impregnations, or paint the concrete after priming and protecting the old compounds, if the structure is strengthened only for preventive measures and to restore the front paint layer. When using screed in areas that get a lot of rain, caution needs to be taken to guarantee excellent waterproofing.
It’s best to hire experts who have the equipment to ensure proper quality and who are knowledgeable about strengthening concrete screeds when planning work on a summer cottage or in the neighborhood.
Typically, businesses that are formally listed on the market also sign a contract with each customer in which they promise a long-term guarantee on the outcome.
Possible difficulties and errors
Every do-it-yourself craftsman may overlook crucial details from the process map when working on the project, which frequently has the following unfavorable outcomes:
- Choosing the wrong material – before buying a composition or membrane for strengthening the screed, it is necessary to draw up a technical task in advance indicating all the required strength characteristics and operational parameters of the structure.
- Poor preparation of the screed before strengthening – the installation of any material for strengthening and protecting the surface of concrete involves cleaning, degreasing and drying the structure. Only in this case, adhesion and long-term operation of the screed will be ensured.
- Incorrect preparation of plastic compositions to strengthen the screed – all construction and finishing materials must be mixed and prepared strictly in accordance with the instructions for using a particular raw material.
- Violation of the technological map when applying material to strengthen the screed – it is necessary to follow the step-by-step instructions, or involve professionals with extensive experience.
- Neglecting the required period of polymerization of the substance after application – in most cases, the expected effect is not achieved, which contributes to the rapid destruction of the coating almost immediately after the start of operational use.
- Choosing the wrong tool – each equipment for installing waterproofing, impregnation or self-leveling floors must be designed to perform this particular procedure. In addition, you should buy only high-quality tools, clean them from dirt, repair them and prepare them for work.
It is advised that you familiarize yourself with video lessons and master classes from professionals who frequently share their experience with other users in the public domain in order to avoid the mistakes mentioned above when working.
