Composition and technical characteristics of quartz primers, rules of application

The use of quartz primer for repairs allows you to increase the degree of adhesion of surfaces and reduce the consumption of finishing materials. In order for the substance to give the desired effect, it is necessary to correctly carry out the preparatory work and adhere to the instructions for applying the substance. Compliance with safety rules is not negligible.

The composition and scope of quartz primers

The main component of quartz soil is quartz sand. This substance helps to increase the degree of adhesion between the treated surface and finishing materials. The sand is finely dispersed. It is evenly distributed over the surface as part of the primer.

In addition, quartz primers may contain the following components:

• Latex, acrylic or acrylic latex substances. These ingredients help retain mass on a wet surface.
• Substances with fungicidal and bactericidal characteristics. They help prevent the development of mold and mildew in rooms with high humidity.
• Resins.These substances give homogeneity to the solution.
• titanium dioxide. This component contains pigments, which helps to apply the primer for finishing.

When the quartz soil dries, a rough structure appears on the surface. This keeps putty, ceramic tile and plaster firmly in place. If during renovation work it is necessary to apply the finishing material in a thick layer, it is recommended to use a special mesh.

The amount of mixture required for wall processing exceeds other solutions. At the same time, a single application of the layer improves the functional characteristics of the surfaces.

Quartz primer can be used for various purposes and tasks. Most often it is used in such situations:

• Finish surfaces with major flaws and cracks. Such a primer is effective even if other materials do not help level the surface.
• Saving coating to be applied.
• Treatment of coatings based on wood-based materials, monolithic concrete, plasterboard, mortars, including acrylic primer.
• Facade works.
• The need to create a transparent coating. It is provided by a sodium silicate primer.
• Canning for the winter.
• Fixing the external thermal insulation on an adhesive base.

When using a quartz floor, it is important to take into account that the main condition for long-term operation is the complete drying of the substance. If the humidity and temperature parameters are violated, the operating time of the coating decreases.

Advantages and disadvantages of use in construction

Quartz wall primer has many benefits. Among them, it is worth highlighting:

• Strengthening the characteristics of the surface and its smoothness.After such events, paint or plaster is applied much easier.
• Fast drying. Once the substance is distributed on the wall, it comes into contact with the surface material. The quartz grain helps to increase the drying speed.
• High degree of reliability. Thanks to special dry components made from organic substances, the wall structure becomes stronger and retains its technological properties well.
• Pressure resistant. Quartz primer is popular because it is very resistant to atmospheric pressure. Thanks to this, it can be used in different conditions.

Quartz primer is characterized by high moisture resistance, the formation of a rough surface and the possibility of subsequent application on various types of plaster. To improve the result, you must first degrease the walls.

At the same time, the quartz primer also has some disadvantages. These include in particular the following:

• Impossibility to apply on dry surfaces. It is important to first treat the walls with water so that they are slightly damp.
• The impossibility of applying mass to polished materials, glass surfaces or polymers. In this case, the mixture does not provide high adhesion. Therefore, there is a possibility of peeling off the decor.
• Risk of mix loss due to direct UV radiation and high humidity.

Features

Quartz Primer is a mixture of acrylic polymers dispersed in water. Pigments and minerals are additionally added to its composition. The soil has a fairly thick consistency, but it includes some quartz chips. This helps to increase the roughness and improve the adhesion of the surface and decorative plasters. The density of the mixture is 1.58 kilograms per cubic decimeter.

It is allowed to apply the primer at a temperature of + 5-30 degrees. In this case, it is important to strictly observe the lower limit of the range. Humidity parameters are not negligible. They must not exceed 80%. The drying time can be from 3 to 6 hours - it all depends on the operating conditions. For 1 square meter, 0.2 liters of soil may be needed. The final value can be increased and is determined by the absorbency.

Hardware Restrictions

In addition, professional masters advise to adhere to the following rules:

• Use only one type of floor in a room. It is forbidden to apply several types of substances at once.
• Do not apply quartz primer to plastic and metal products. This is due to the fact that they do not absorb mass. After drying, the sand crumbles.
• Do not use primer when exposed to direct sunlight. This causes a violation of the structure and a decrease in the quality of the finish. After drying, there is a high probability of sand flaking.
• The composition is allowed to cover only the walls. For ceilings, sand-based flooring will not work. In case of accidental moisture entry, it will immediately exfoliate.
• Do not apply the composition in conditions of high humidity in the room.
• At negative temperatures and parameters above +30 degrees, it is better not to use quartz soil.

Varieties of quartz primers and recommendations for choice

There are many quartz sand primers on sale today. They differ in composition and technical properties. Each package contains instructions that indicate the scope and application rules of the substance.The most common options for such floors include:

• Suspension based on synthetic resins. It is characterized by high safety and the absence of chemicals in the composition. The compound can be applied on smooth walls. The substance can be used both indoors and outdoors. The ideal temperature for use is +20 degrees. In this case, the floor hardens in 3-4 hours.
• Composition dispersed in water containing latex and acrylic resins. The substance is resistant to atmospheric fluctuations. The composition perfectly repels water and dries quickly.
• Composition based on silicate. The substance easily penetrates into small cracks and pores. It can be used in rooms with high humidity. In this case, the mass dries long enough - it takes about 12 hours. Another disadvantage is the high cost of the composition - 400-600 grams.
