During the repair and construction work, in addition to leveling and painting the walls or wallpapering, builders recommend priming. Today you can find a large number of products that are used only for metal, plaster, wood or concrete substrates, but also produced latex primer, which is a universal building material.
Application
A mortar is used to process walls of brick and concrete, as well as plastered surfaces or chipboards. Without a primer mixture, good coating strength will not be ensured, the base's resistance to external negative factors will decrease, and the adhesion of the surface to the finish will be minimal.
The latex-based acrylic primer is used for indoor work and is excellent for treating porous surfaces. According to the reviews of the builders, the soil is perfectly absorbed, which allows for further finishing operations with a minimum consumption of material.
Structure
The primer mixture is a water-soluble and safe repair and construction material, which, after application, most often forms a matte vapor-permeable film. The composition of the soil includes the following main components:
- styrene-acrylic latex;
- antifoaming agents;
- antiseptics;
- oils;
- preservatives;
- drying accelerators;
- pigments.
Acrylic and latex primer - what is the difference?
Many specialists who work in the construction and repair sector are wondering which primer is better - latex or acrylic? It would seem that both solutions are designed to prepare the bases. But what to choose, you can decide only by studying the instructions for use.
When choosing a consumable, it should be noted that the difference between these two primers is that acrylic does not protect against the corrosion process, and latex just provides reliable protection against the negative impact of the external environment. In addition, deep penetration latex primer can still be used in wet rooms. It is important to pay attention to the composition of the emulsion, which may vary.
Benefits of Latex Primer
Latex-based emulsions provide unique results, especially when applied on uneven surfaces. Among the main advantages of latex primers are the following:
- The composition contains no harmful substances that are harmful to human health or damage to the environment.
- They increase the protective properties of the walls, give the finishing materials high resistance to moisture.
- The emulsion dries quickly enough.
- Adhesion to different wall bases is enhanced.
- Increases resistance to mold, fungi, etc.
Foundation preparation
Before applying a primer on a latex basis, the surface of the base must be prepared. Tools required:
- Wide brush.
- Thread or fur roller.
- Special trough for soil.
- Rag.
To prepare the base, it is necessary to remove all dust, mold, grease stains, construction dirt from it. If necessary, the surface of the base is treated with a special antiseptic. After the preparation procedure, the wall should dry well. If cracks are noticed on the wall, then at first they are embroidered, after which they are sealed with special mixtures or plaster.
Soil application
If the room is furnished, then all objects must be covered with plastic wrap, also protecting all other surfaces, for example floors, because the spots of the primer are quite difficult to remove. In addition, it is important to protect the eyes, head and skin when working with building materials. For this, glasses, a hat and thick work clothes are quite suitable.
Important! It is necessary to carry out work at an ambient temperature of at least + 10 ° C and at an air humidity of not more than 75-80%.
The solution is poured into a tray, after which the necessary areas are treated with a roller. You can also use a brush to prime hard-to-reach spots. Experts recommend applying the soil to the base in two layers, so that the surface is completely saturated with a primer mixture. Each subsequent layer of the emulsion is applied after the previous layer has dried. If the mortar enters the skin or eyes, immediately rinse with clean tap water.
Soil "Lahti"
Lakhta latex primer is a one-component emulsion that has a milky white color. Soil can be used both in diluted and in concentrated form. The proportions of dilution directly depend on the nature of the surface being treated and the purpose of the work. Using this primer, it is allowed to process such substrates: concrete, iron, gas and foam concrete, brick, gypsum stone, wood.
Builders note such advantages of the material:
- Decreased ability of the substrate to absorb moisture from the environment.
- Strengthening the surface of the material.
- Improving the adhesion of waterproofing, repair and finishing materials to the base.
Soil "Snowball"
Primer solution “Snezhka Soil” is a mixture of pigments and fillers, latex resin with the addition of auxiliary agents.
The use of the Snezka Grunt emulsion significantly reduces the cost of repair and construction work, since to achieve the expected effect it is enough to apply only one coat of primer, after which finishing and decorative coatings are already applied.
Soil mortar is used for single-layer processing of cement, gypsum, wooden surfaces indoors. The emulsion should be superimposed with a thick layer, which allows you to get rid of the roughness of the texture.
According to the reviews of the builders, it is clear that the latex primer significantly reduces the absorbing properties of the surface, therefore it is most often used for the first painting of gypsum boards and surfaces after leveling (for example, using gypsum).
Soil TIKKURILA
This type of primer is characterized by excellent adhesion to clean and previously painted inks and acrylic surfaces. Matte acrylic-latex primer is used for processing concrete, cardboard, plastered, putty, brick surfaces, as well as boards from wood shavings and wood fibers.
The universal type of primer on an acrylate base contains additives that protect the paintwork from mold.
Grid soil
Deep penetration latex primer with Grid acrylic is used to strengthen substrates with a high degree of absorption and to prepare the surface for the application of finishing or decorative materials. According to customer reviews, the Grid primer reduces the consumption of topcoats and improves adhesion.
The primer can be applied to such substrates: brick, plastered surfaces, drywall, wood, cement, concrete, etc. Advantages of the Grid primer:
- The primer has an antiseptic effect.
- The expendable material is used for external and internal works.
- Soil is excellent for processing various types of surfaces.
- The emulsion is environmentally friendly to human health and the environment.
Ease of use, versatility, and the ability to quickly dry out make the latex primer in demand among ordinary consumers and professional builders. However, it should be remembered that in working with the soil it is required to observe both the instructions for its use and the priming technology.
