Types of the primer that are used for the floor for linoleum, the features of the application

Using the proper primer during linoleum installation is crucial to achieving a smooth and long-lasting finish. Primers help to improve adhesion, prepare the floor, and lengthen the life of your linoleum. Your flooring project’s result may differ significantly if you are aware of the various primer types and their intended uses.

For linoleum floors, a variety of primer types are frequently utilized. Acrylic primers are widely used because of their speedy drying times and versatility. They provide a sturdy foundation for the linoleum adhesive to adhere to, making them appropriate for a range of surfaces, such as plywood, concrete, and wood. Conversely, latex primers are well-known for their superior sealing capabilities and capacity to form a barrier that is resistant to moisture, which makes them perfect for locations that are subject to moisture.

Another great option is epoxy primer, particularly for high-traffic areas. They provide outstanding resilience to chemicals and wear, guaranteeing that the linoleum will remain securely in place even with frequent traffic. Self-leveling primers are also frequently utilized, especially in situations involving uneven flooring. These primers aid in producing a level, smooth surface, which is essential for attaining a polished linoleum flooring finish.

Primer application is simple, but it needs to be done carefully. The floor surface needs to be completely cleaned and dried before applying in order to get rid of any debris, oil, or dust that could prevent the material from sticking. Following the manufacturer’s instructions, it’s crucial to let the primer dry completely after applying it. In order to get the best results and guarantee that the linoleum flooring lasts a long time, this step is essential.

Your linoleum floor’s performance and appearance can be greatly improved by selecting the appropriate primer and applying it correctly. It’s possible to guarantee a more seamless installation procedure and a long-lasting, aesthetically pleasing floor by investing the necessary time in surface preparation.

Do you need to be primed before laying?

The concrete base must be ready before linoleum is installed. Protrusions, chips, bumps, uneven surfaces, or "slopes" are polished. Concrete solution is used to cover pits, cracks, and cracks; if necessary, screed is made. After that, construction debris is cleared from the base and fine dust is vacuumed away. They perform wet cleaning as needed.

Additionally, the base of any flooring should be primed beforehand using a unique primer that:

• does not allow the cement screed to “dust”, increases its resistance to moisture;
• additionally strengthens the base;
• “closes” all microcracks and porosity – the risk of mold or mildew, even in a room with high humidity, is greatly reduced;
• protects against external aggressive influences – provides waterproofing and tightness;
• improves the performance characteristics of the floor finishing coating.

Improved linoleum adhesion to the subfloor is guaranteed by the primer.

For what types of grounds??

Before installing linoleum, a primer is necessary for a concrete base. In addition to preventing damage to the subfloor, it also

• makes it stronger;
• reduces absorbent properties;
• guarantees a significant reduction in the consumption of adhesive components when laying linoleum.

After priming, the amount of glue that the concrete absorbs is significantly decreased, saving money because less glue is needed to install the coating.

Because of its increased porosity, the cement-sand base needs to be primed with specific deep penetration agents. The primer precisely fortifies the content.

Additionally, primer needs to be applied underneath the covering on a wooden base. Additionally, it will shield the subfloor from any potential mold, mildew, or moisture penetration.

A specifically formulated primer on a plywood "substrate" will lessen the degree of moisture penetration, provide mold and fungus resistance, and increase the material’s lifespan.

Following priming, the polymer screed ensures an absolutely level subfloor base, making linoleum installation a lot easier.

Various primer types are available from manufacturers, each intended for a specific substrate. Take epoxy for concrete, for instance. Alkyd primer: for subfloors made of metal and wood. However, universal products are also available, like acrylic primer, which can be used to treat any kind of surface.

For what coatings?

There are two main methods for laying linoleum: using glue or just laying it on a dry surface. If linoleum is to be glued to the floor, the base of the floor is typically primed. However, experts advise priming in any case before laying linoleum, including on wooden bases in addition to those made of concrete or cement. By doing this, the materials will be more adherent and protected.

Selecting a primer is necessary for linoleum. For instance, natural material coatings shouldn’t be applied over primers whose composition includes ingredients that might harm the former. This holds true for PVC flooring as well. It is preferable to choose water-based.

You can use a solvent-containing primer if the linoleum is multilayered and the thicker felt layer at the bottom is chemical resistant. However, the priming should be fully dried before applying the finishing coat.

Types and types of compositions

There are two types of primer compositions: deep penetration and superficial penetration. The first increase the strength and durability of the floor base, while the second one greatly improves the adherence of materials and surfaces that come into contact.

The following categories apply to the primer:

1. Water soluble – recommended for treating not only floors, but also walls and ceilings. Has a minimum price and is the most popular option. Also dries quickly and has no pungent chemical odors. The downside is the inability to penetrate deeply into layers of concrete and cement.
2. Organic – capable of penetrating deeper into the surface of concrete. Guarantees increased strength and durability of the coating. This option is most appropriate on loose, fragile floor foundations. The downside is the high price and mandatory compliance with the instructions during application.
3. Polyurethane – recommended for substrates subject to heavy loads, as well as in industrial premises. This product is expensive. During operation, after priming, cracks and chips are still possible.

Prior to making a purchase, you should inquire with the vendor about the product’s intended use and consider the type of floor that will serve as the base for the linoleum once it has been primed.

Primers fall into two categories: universal and specialized.

Expensive starting at 7,000 rubles for a 10-kg container.

Many opt to make their own primer with combinations of acrylic and PVA glue, which is the traditional method. It needs to be prepared in small amounts and consumed right away because the properties "lost" quickly.

How to choose the right one?

Primer chosen with consideration for the room’s size, the floor’s base, and its intended use:

1. For concrete screed, it is advisable to choose an acrylic or epoxy primer with deep penetration.
2. Wooden floors are primed with special alkyd, acrylic or polystyrene options. But you should know that polystyrene is not the best option for small spaces; it is used in outbuildings, when finishing corridors, entrances, and industrial areas.
3. If the base of the floor has metal components, then you can choose a universal primer that is suitable for all surfaces.

It is best to select a primer that won’t harm the linoleum finishing coating and is appropriate for it. The safer the primer composition, the smaller the room that will be used for processing.

When applying a primer in a space without heating and potential for continuous high humidity, pick formulas with antiseptic and moisture-repellent ingredients.

Selecting the appropriate primer is essential when getting a floor ready for linoleum installation. This article examines the many kinds of primers that are used, emphasizing their unique uses and advantages. Knowing these primers and how to apply them correctly guarantees a level and long-lasting linoleum base, increasing longevity and performance. Does this fulfill your search criteria?

Tools and consumables

The workflow will require the following tools:

• containers for diluting the primer;
• rollers, brushes;
• spatulas;
• metal brushes – for removing construction debris from hard-to-reach places;
• drill with disk brush attachments;
• heat gun;
• mechanical stirrer.

Personal protective equipment (goggles, gloves, and respirator).

Step by step instructions

The primer is applied prior to the actual linoleum installation. The subfloor base’s surface needs to be ready already (clean, level). The work is completed step by step:

1. The primer is prepared. The dry mixture is diluted (according to the instructions) with water or solvents, etc. The liquid solution of ready-made primer from the store is first mixed well (until a homogeneous mass). A homemade primer is created in a 1:2 ratio (PVA glue and water) and mixed with a construction mixer.
2. Using rollers or large brushes, apply the primer in even layers over the entire surface of the base.
3. First, carefully coat the corners, seams and edges of the subfloor.
4. Work is carried out starting from the far corner, to the exit from the room.
5. Wait the required time, according to the instructions, so that the base dries completely.

If required, carry out the process once more. This is a cost-effective solution for major repairs in buildings with high depreciation (secondary housing, etc.) when high humidity is achievable and on the first and last floors with high heat transfer. No puddles or unprimed areas from an overapplication of primer solution should remain on the treated surface.

Priming can be carried out with mastic if the linoleum is first fixed with it. An even layer of this adhesive mixture is applied to the surface after it has been diluted 1:2 with solvent and water. After 6 to 12 hours of full drying, install the linoleum.

Difficulties and errors of the process

The following mistakes could happen while working:

• there was not enough primer to apply evenly over the entire area of ​​the room – you should first determine the area of ​​the room and how much primer will be needed for it, otherwise you will have to purchase additional goods;
• for a concrete base, you purchased a primer intended for wooden floors – you should replace the product with the required one, otherwise the concrete will not receive a “deep” enough penetration of the protective agent;
• after priming, do not wait for it to dry, immediately lay the linoleum – this can “start” the process of early wear, since wet chemicals under the topcoat can quickly destroy the linoleum;
• We used two different (by type/type) primers – different compositions will “protect” the subfloor in different ways and affect the linoleum, this is unacceptable.

We applied a primer to the base without first clearing any dust or small pieces of construction debris. The concrete base and the finishing coating will suffer as a result of this.

Advantages and disadvantages

There are certain benefits and drawbacks to initially priming a floor under linoleum.

Advantages

• provides better waterproofing and moisture protection;
• guarantees adhesion;
• strengthens the foundation;
• fills the smallest chips, cracks, flaws;
• Levels the surface as much as possible;
• minimizes concrete porosity, penetrates deep;
• different types and types;
• for deep or superficial effects;
• the floor surface treated with a primer requires less glue for laying linoleum;
• if linoleum is laid using glue, then preliminary priming will ensure a high level of adhesion of the materials.

Versatility: models are available for every kind of floor surface. Additionally, you can select items made of various materials, such as concrete, wood, cement, metal, etc., that are intended for a particular subfloor.

Tiny dust particles may build up beneath the linoleum finishing coating while it is in use. It gradually starts to seep into the space through baseboards and joints. The subfloor can be primed to totally solve this issue.

Minuses:

• you should choose a primer according to its intended purpose;
• the product may contain toxins and unpleasant odors;
• In order for there to be enough material for uniform coating over the entire area of ​​the room, it is necessary to set the required amount of this product in the store.

When performing the work in accordance with the instructions, safety gear must be worn.

Average prices for work

Skilled Russian builders provide the following services for priming floors beneath linoleum:

• primer 130-170 rub. m 2;
• dust removal 60-100 rub. m 2;
• concrete floor 140-190 rub. m 2;
• under linoleum 280-400 rub. m 2;
• processing in two layers from 300 rub. m 2 .

The costs rise sharply if turnkey work is needed, which entails leveling the base’s surface, caulking cracks, clearing away construction debris, determining the number of floors, and traveling to the job site. Prices will vary based on the location and area of the premises in each individual case. It may start at 5,000 rubles or more.

Further details regarding the video’s primer:

Primer Type	Features of Application
Absorbent Primers	Used on porous surfaces like concrete or wood to enhance adhesion and prevent moisture absorption.
Non-Absorbent Primers	Designed for non-porous surfaces such as existing tiles or old linoleum; they create a bonding layer for new linoleum without soaking into the substrate.
Multi-Surface Primers	Versatile primers suitable for various substrates, offering good adhesion and compatibility across different materials.
Moisture Barrier Primers	Applied to prevent moisture from affecting the linoleum, especially useful in damp environments or over concrete floors prone to moisture.

Selecting the appropriate primer is essential for linoleum installation. Primers get the subfloor ready, which improves linoleum adhesion and longevity. They provide a smooth, level surface for linoleum installation, seal porous surfaces, and stop moisture from leaking in.

Acrylic primers are perfect for subfloors made of concrete or wood. They improve bonding and lower the possibility of moisture damage, both of which are critical for preserving the longevity of your linoleum. Additionally, primer application increases the floor’s resilience to abrasion.

The primer can be applied simply. To start, give the subfloor a thorough cleaning to get rid of any dust or debris. The primer should then be applied evenly over the whole surface using a brush or roller. Let it air dry completely before starting the linoleum installation.

Recall that your linoleum flooring’s performance and lifespan are directly impacted by the quality of your primer. Purchasing a high-quality primer guarantees that your floor will be strong, cleanable, and aesthetically pleasing for many years to come.
