To guarantee a seamless and long-lasting installation, there are a few crucial steps involved in preparing a concrete floor for linoleum. The longevity and aesthetics of the linoleum are greatly influenced by the state of the concrete surface. Thoroughly clean the concrete floor to get rid of any dust, debris, and leftover paint or adhesive before starting any work. By doing this, a clean surface is guaranteed for the new flooring material to adhere to properly.
Examine the surface of the cleaned concrete for any holes, cracks, or uneven patches. The durability and ease of installation of the linoleum may be impacted by these flaws. Using an appropriate patching compound, seal any holes or cracks, and use a self-leveling compound to even out any uneven areas. To get a smooth, consistent surface, smooth these repairs in accordance with the manufacturer’s instructions.
It’s critical to take the concrete’s moisture content into consideration after repairs are finished and the surface is smooth. Because concrete retains moisture, linoleum may eventually become damaged. Use a plastic sheet test or a moisture meter to test the concrete’s dryness to see if it’s ready for installation. Before moving further, adhere to the manufacturer’s recommendations regarding acceptable moisture levels.
After that, prime the prepared concrete surface with an appropriate primer. The linoleum performs better thanks to the primer, which also forms a barrier against moisture and enhances adhesion. Before installing the linoleum, let the primer completely dry in accordance with the manufacturer’s instructions. In order to guarantee a solid bond between the concrete and the flooring material, this step is essential.

Needed or not?
Construction technology dictates that preparatory work needs to be done. The finishing coating’s porous rubber structure is the cause of this requirement. It is thought that linoleum is a universal material. It will, however, tear quickly on an unprepared surface with variations in the base’s level. Tensile loads in areas where the floor is deformed will result in breaks.
Changes in smooth waves also cause the material to react negatively. The linoleum will distort in this instance due to the inadequate fit.
To lay linoleum, a stable, smooth, and long-lasting base is required. Allowable base evenness deviation: up to 2 mm per 2 m surface.
The state of the concrete screed determines the list of necessary preparations. You will have to conduct an assessment in order to ascertain it.
Assessment of the condition of the rough foundation
At this point, it’s important to ascertain:
- screed strength;
- presence of irregularities;
- number of flaws, their condition.
Leveling the concrete floor should not be disregarded, despite the list of flaws that have been noted. Any irregularity will eventually leave its mark on the elastic linoleum, causing folds to form and the coating to wear down too soon.
Determining how to level the floor also requires evaluating its condition. For instance, it is advised to use grinding to eliminate minute variations (up to 2 mm per square meter). You’ll need to create a new screed in order to level out significant differences. How to carry out an evaluation
- If there is an old coating on the rough base, it must be dismantled.
- Visual inspection of the screed and quality assessment should be carried out after dismantling, cleaning the surface and removing dust.
- Measure the level of differences using a construction, laser or water level. The rail should be 2 m long.
- Assess the quality of concrete floor waterproofing by the presence or absence of dampness.
It is acceptable in some situations for the base to have a slight uniform slope in one direction.
Methods
There are a few fundamental preparation techniques in addition to others. Their purpose is to smooth rough foundations. Every choice has a particular application. Put differently, the selection of a preparation method is contingent upon the kind, amount, and presence of defects.
Grinding
This is among the options for preliminary work that are most frequently used. When there are minor variations in the concrete screed (up to 5 mm), the technique performs well. these consist of swells and ripples.
Waves are not eliminated by grinding.
A grinder can be used to remove a few defects. You’ll need a specific attachment for grinding, such as a corundum grinding or a diamond bowl. The kind of concrete determines the kind of nozzle to use. It is advised to use diamond segments for high-strength mixtures and corundum segments for low-strength grades (below M250).
Additionally, the grinding process aids in opening the screed’s top layer’s pores, allowing impregnating solutions to more easily penetrate. Sanding usually comes before priming; it’s not the last step in the preparation process.
This kind of work is especially dusty, so a vacuum cleaner is needed.
Puttying
An essential step in the linoleum installation process is floor preparation. The finishing coat will become less visually appealing and last much shorter without puttying.
Strong>The crucial details are as follows:
- choice of material;
- compliance with the technical process.
Concrete putties come in a variety of varieties. The most affordable and straightforward solution is dispersion putty. It is applied in a "scratching" motion using a flat spatula.
Minor irregularities are evened out and all existing scratches and chips are penetrated by the composition. Ideal for laying new concrete screed before installing linoleum.
Puttying primarily aims to strengthen concrete, level the surface, and lengthen its service life. In order to achieve an excellent outcome, pick a putty that possesses these qualities:
- increased elasticity for even distribution on the floor;
- the absence of large particles in the composition so as not to damage the base;
- good adhesive properties;
- environmental friendliness;
- fire resistance.
You can attain the perfect level of evenness in the concrete floor by using proper puttying.
The components of different compositions vary. Materials based on oil, adhesive, lime, acrylic, cement or gypsum, and oil are available. As you go through the selection process, you should become familiar with the benefits and drawbacks of each variety. Deep penetration putty is recommended when working with concrete.
The material can be used to seal a limited number of flaws and minor level differences. If there is a lot of damage to the floor, you should prepare it differently.
Repairing cracks and chips
Following the fixing of chips and cracks:
- further coloring of concrete along the edges of the defect is prevented;
- subsequent elongation and expansion of cracks is excluded;
- linoleum is protected from holes in it.
Applied to seal fractures:
- polymer-modified concrete mortar (cement + latex);
- epoxy and polyurethane compounds;
- PVA-based mixtures.
In the event that the gap is tiny (less than 2 mm), 10 mm of embroidery should be done initially.
Next:
- the seam must be removed from dust using a vacuum cleaner;
- fill the cavity with polyurethane or epoxy primer diluted with solvent R-646 in a ratio of 1:10;
- fill the seam with a repair mortar based on epoxy resin;
- fill the hole with repair compound;
- sand after drying.
The method for handling chips and deep cracks:
- cut a crack to a depth of 50 mm using a grinder;
- cut 2 channels along it on both sides;
- clean them from damaged concrete;
- deepen and remove dust from the crack;
- prime with epoxy or polyurethane compound;
- fill the cut with repair mixture;
- re-prime.
- sand the surface to floor level.
Leveling mixtures
An easy and rapid method for readying a concrete floor for linoleum installation. phases of the project:
- clean the surface of the screed from debris and dust;
- fill large defects with a quick-hardening mixture to roughly level the floor;
- prime the surface;
- mix the self-leveling floor solution according to the manufacturer"s instructions;
- stand for 2-3 minutes to start chemical reactions;
- pour the solution onto the surface of the screed;
- level the mixture with a spatula or squeegee, the layer thickness should not be less than 5 mm;
- remove air from the layer using a needle roller.
Once the layer has dried for a full day, no further processing is needed. Are you able to lay vinyl?
Substrate
A unique synthetic material called underlay is placed between linoleum and concrete floors. Rolls or sheets are available. Such a layer can be anywhere between 2 and 10 mm thick, depending on the substance.
After fixing the substrate to the rough base, linoleum is installed on top. One person can manage the rolls because they are not heavy. Placing the substrate:
- provides good sound insulation of the room;
- reduces the level of heat loss (works as insulation);
- levels out minimal unevenness on the concrete base;
- extends the service life of linoleum due to its isolation from concrete.
The base of the linoleum needs to be put in:
- private houses and apartments with an unheated basement;
- old buildings with poor sound insulation;
- rooms with cold floors;
- rooms with uneven floors and minor defects.
You can only install the underlay on a spotless floor.
How to prepare a low quality base?
Liquid epoxy impregnation or a comparable composition will be helpful in this situation. They will offer a notable boost to the screed’s brand strength. Algorithm of work:
- clean the screed from debris and dust;
- lay waterproofing material;
- prime and impregnate with epoxy compounds;
- lay the leveling mixture.
After that, you can begin installing the carpet.
Treatment of the coating before installation
It is advised to prime the concrete base prior to laying out the roll covering. It is crucial to finish all application technology stages and select the appropriate kind of mixture. When operating linoleum, a well-executed procedure will eliminate many issues.
Goals
Primer application produces an excellent protective layer. Gender-appropriate surface priming:
- will eliminate minor defects, which will simplify subsequent installation work;
- forms a protective film that prevents the absorption of moisture by concrete and the formation of mold;
- will significantly increase the level of adhesion of materials when laying linoleum with glue;
- effectively removes dust from the surface of the screed and prevents dust from entering the room.
The benefits listed suggest that a similar procedure should be carried out prior to linoleum installation.
What is the best way to process?
Make your composition selection before you begin. There are various kinds of primer, so you must be aware of their characteristics and subtleties of use.
The soil needs to be perfectly adapted to certain circumstances:
- Aqueous or water soluble. This is the most popular type that can be used to treat not only the floor, but also other surfaces. It is characterized by its low price, lack of pungent odor, and dries quickly. The disadvantage is shallow penetration into concrete.
- Organic. This type has a large penetration depth. When processing the subfloor, its strength increases significantly. Ideal for loose substrates. Disadvantages include high price, small assortment, high demands on conditions of use and application technology.
- Polyurethane. This type of soil is used in rooms with high operational load. After treatment, the wear resistance of the rough base improves, recommended for industrial linoleum. Disadvantages – cost, does not prevent chips and cracks during operation.
The manufacturer’s instructions for processing must be visible on the box or packaging.
Step-by-step instruction
The last step in getting ready to lay linoleum is priming the base. First, make sure you have enough tools. Will require:
- Composition tray. If the soil is already ready, then you can work directly from the container.
- Brushes. Take several sizes so that you can treat any area.
- Rollers for uniform application of primer.
- Spray. Convenient when working over a large area.
Algorithm of work:
- thoroughly clean the rough base from debris and dust;
- prepare the soil according to the instructions;
- use a brush to treat all hard-to-reach places;
- apply primer to the floor with a roller;
- allow time for the composition to dry;
- if necessary, repeat priming.
The smooth, resilient, and long-lasting finish of linoleum depends on the concrete floor being properly prepared for it. This procedure entails completely cleaning the floor to get rid of any dirt or debris, filling in any holes or cracks to make the surface smooth, and using an appropriate primer to improve adhesion. In the end, making sure the concrete is totally dry and level will ensure that your linoleum floor looks fantastic and lasts a long time by preventing problems like bubbling or uneven wear.
Errors and their consequences
When preparing a concrete base, it’s important to stay away from mistakes that could cause issues:
- Refusal to assess the condition of the screed. Not all defects are immediately visible. Some problems can only be detected by careful inspection of the surface. If this is not done, then the remaining shortcomings will subsequently lead to a decrease in the quality characteristics of linoleum.
- Neglecting the leveling step. It is necessary to choose the correct leveling method so that the floor surface is level. Otherwise, the appearance of dips, breaks, abrasion of linoleum, and a reduction in its service life cannot be avoided.
- Failure to use primer mixtures before installation. This stage significantly improves the strength and quality of adhesion of materials, and removes dust from the surface. In the absence of priming, the service life of linoleum will be significantly reduced.
The size of the anticipated loads and the room’s area should always be your main concerns. This determines the base preparation technique and material selection.

Regarding the video’s installation features:
For a seamless and durable finish, careful preparation of a concrete floor is necessary before installing linoleum. Start by giving the concrete surface a thorough cleaning to get rid of any debris, dust, or dirt that can interfere with adhesion. This stage is essential because it makes it possible for the adhesive and concrete to properly bond.
Next, look for any uneven patches or cracks in the concrete. Use a self-leveling compound to level out uneven areas and use an appropriate filler to seal in cracks. This guarantees a level surface, which is necessary to avoid dips or bumps beneath the linoleum.
It’s crucial to let the compound cure completely in accordance with the manufacturer’s instructions after leveling. Skipping this step could result in issues down the road with the stability of the floor and the longevity of the linoleum.
After the surface is dry, clean, and level, apply a primer that is appropriate for both linoleum and concrete. Enhancing adhesion and guaranteeing that the adhesive binds well to both surfaces are the functions of the primer.
Lastly, pay close attention to the manufacturer’s installation instructions when laying the linoleum. When linoleum is laid and adhered correctly, it not only looks nice but also lasts longer and is more durable. You can have a long-lasting concrete floor that is ready for linoleum by adhering to these simple guidelines.
