Varieties of floor primers: how to choose the right one?

Today, in stores of building and finishing materials, you can find various types of primers, designed for different bases. Recently, high-quality compositions for finishing the floor have been very popular, since they can be used not only to level the surface with waves and drops, but also to provide it with increased waterproofing characteristics. Today we will talk about the existing varieties of floor primers..


The primer is one of the most common and demanded finishing materials. It is used for different purposes.. Let’s consider them in more detail.

  • A good quality primer can be used to level the surface of the subfloor. Many finishing materials (for example, porcelain stoneware, laminate, parquet, tiles or linoleum) must be laid on a prepared base.To achieve the desired effect, you simply cannot do without a primer.
  • The primer is often laid on a cement screed. Due to this tandem, cement substrates become more flexible in work. It becomes much easier to lay other coatings on them..
  • Finishing floor materials that have been laid on a base covered with soil have a longer service life. This effect is achieved by increasing the degree of adhesion of the coatings. Due to this feature, the finish is not prone to cracking, chips or delamination..

  • The concrete surface of the floor becomes more durable after soil treatment. Therefore, many consumers are in a hurry during repairs to strengthen the floor bases with a high-quality primer. Without it, concrete can collapse over time..
  • The primer is designed to protect the subfloor from aggressive chemicals. Few people know that dampness and substances dissolved in it are able to penetrate the putty on different bases. This often leads to chemical reactions that have a detrimental effect on the finishing materials. With the help of a high-quality primer mixture, you can forget about such problems..
  • The primer allows you to significantly save on subsequent finishing materials, since it closes the pores in the base structure.
  • It is necessary to maintain the natural moisture level in the substrate. The surface that has not been finished with primer, as a rule, is too dry or too damp, and this has a very detrimental effect on the durability and strength of the floor base.
  • Special primers with a high degree of moisture resistance are often used if there is a “warm floor” system in the room. Such mixtures are often used before laying tiles in rooms with a high level of humidity (kitchen, bathroom, toilet).

I need a primer so that dust does not accumulate on the finishing of the base. It is a very useful addition to the subfloor. Due to it, the base and decorative material will serve for a long time without causing any hassle..

Types and properties

Currently, there are several varieties of primers. Each of them has its own characteristics and properties. Due to the choice provided, a suitable composition can be purchased for any conditions.


These primers are common in stores. They are purchased mainly for finishing capricious wooden surfaces before painting them. There are two types of alkyd primers. The choice of the best option largely depends on what kind of paint you plan to transfer to the wooden floor.. After complete application, such mixtures dry in about 10 hours..


These types of soil are quite popular. They are in demand as they are ideal for finishing metal surfaces. However, glyphthal solutions can only be used in closed rooms, in which there are no drafts. Such primers dry out in a day (sometimes a little longer). Today in stores you can find a good alternative to glyphtal primers – zinc-rich mixtures.


This two-component mixture is most often used to decorate concrete substrates. With its help, the surface of the base can be made more durable, reliable and wear-resistant. In addition, after applying the epoxy, the floor becomes more moisture resistant. Epoxy mixtures are often used as an independent layer. They have high adhesion. The epoxy primer contains no aromatic solvents, so when working with it, you will not feel an unpleasant and pungent odor.


Such primers are used for brick and plastered surfaces. However, experts say that perchlorovinyl compounds should be used only when the object to be treated is located outdoors. These types of soil are often applied to concrete outdoor areas or screeds. If you are going to purchase this primer mixture for a screed, then you should choose it based on the material from which the base is made (and not the screed itself). Perchlorovinyl mixtures dry quickly enough. This takes about 1 hour..

Polyvinyl acetate

These types of primers can be used if you plan to paint the base with polyvinyl acetate paint. In this case, the type of material from which the floor is made does not matter. This type of mixture dries in record time: it takes only 15-20 minutes..


These types of primer should be purchased for wood floors and plaster subfloors. In addition, polystyrene primers are often used for the subsequent installation of a self-leveling floor. It should be noted that polystyrene compounds cannot be called environmentally friendly and absolutely safe.

They contain aggressive and toxic compounds. For this reason, the use of such mixtures in confined spaces is strongly discouraged, otherwise you may harm your health..


One of the most popular and demanded types of primer is acrylic mixes. These products are distinguished by the fact that they are suitable for almost any floor base. In addition, they do not have an unpleasant and pungent odor, so it is quite easy to work with them. Many consumers choose acrylic mixtures for the treatment of substrates, since they can be used for finishing concrete floors..

Solutions penetrate into its structure to ensure increased adhesion. These properties are especially useful if you plan to install laminate or linoleum on your floor. Also, acrylic compounds can be used when decorating a floor screed..

It is not recommended to use acrylics for finishing dark iron: they can cause corrosion on such substrates..

If you do not want to spend extra money, you are confident in your abilities and knowledge, you can make a primer yourself. Today there are many different recipes, adhering to which you can create a really high-quality and practical soil..

At the same time, it is important to carry out the manufacturing technology as accurately as possible., in order to end up with a liquid of the desired consistency and quality. Consider the features of the choice of purchased material.

How to choose?

As you can see, the assortment of primers is quite rich. Each consumer has the opportunity to choose the ideal option for himself.. Take note of the specific advice of experts in the field of construction and renovation.

  • The choice of the optimal composition, first of all, depends on the material from which the floor is made. For example, for finishing a concrete base, experts recommend buying an acrylic or epoxy mixture..
  • If you want to buy a primer for a floor consisting of wood (chipboard, MDF, OSB), you should look for a special option that has the ability to deeply penetrate. Alkyd, glyphthalic, polystyrene and acrylic solutions are suitable for this description..
  • If you are going to prime the floor in a room that has a high level of humidity or does not have heating systems, it is better to give preference to a composition that contains special water-repellent components..

  • If you are going to prime the floor base under varnish, you should choose a colorless transparent compound. With its help, you can successfully emphasize the structure of the tree..
  • If you want to achieve the effect under the paint, then you should purchase a colored primer..
  • When planning the subsequent laying of the tiles, it is worth using a primer that will ensure the minimum absorption of the substrate. This is necessary so that the base does not take water from the adhesives..
  • For the floor, polystyrene primer is ideal. However, when working with it, one should not forget about its toxic composition..
  • Don’t look for overly cheap primers. Too low a price may indicate poor quality of the composition. Instead, buy branded products from well-known and trusted brands. Such mixtures will delight you with the durability of the flooring and high quality..

Application Tips

Priming the floor is not the most difficult task. Even an inexperienced home craftsman can easily cope with such work.. Here are some simple professional tips to help you prime your floor.

  • Remember to prepare the substrate for future primer application. It needs to be dried if it is damp. In addition, all debris, dirt and dust must be removed from the floor..
  • Sand the base if necessary. After that, cleaning should be repeated..
  • It is necessary to prepare the mixture based on the instructions that the manufacturers indicate on the branded packaging. If you do not want to mess with the dry composition, it is worth purchasing a ready-made mixture that does not need to be prepared for finishing work..

  • After that, you need to dip the roller into a container with prepared soil. Apply the mixture on top of the cleaned base before dust settles on it..
  • First, the roller should be led parallel to one of the walls, and then perpendicularly (along the same wall). This application is considered to be of the highest quality and most convenient..
  • After that, you should thoroughly smear all the corners in the room. You can use a brush. We must not forget about the joints that are between the floor and ceilings..
  • Never skip any areas of the floor during priming. Do not use too much primer..
  • It is necessary to cover the entire area of ​​the rough floor base with primer. After that, he needs to be allowed to dry, and then apply a second layer of the composition.
  • If you are not comfortable working with a roller, then you can easily use a special brush with a long handle..

Security measures

When working with any primer mixture, we must not forget that it is a chemical product. Experts strongly recommend using thick gloves when working with such formulations. Try to avoid getting the solution on exposed skin. Sometimes craftsmen do not do with ordinary gloves – they specially purchase painting overalls. Some people find them uncomfortable, but in terms of security, this flaw is not so important..

Do not forget that many types of primers are difficult to clean from different surfaces. If you accidentally get your hands dirty with these compounds, they will remain dirty for several days.. Polystyrene primers are rightfully recognized as the most toxic and hazardous to health.. You need to work with them especially carefully and prudently. Never finish the floor with this mixture in a completely closed room. Experts recommend that you wear special masks and gloves as high as possible when working with polystyrene primers..
