Quartz primer for walls: 5 stages of applying the composition
To provide a perfect interior or exterior wall decoration of concrete and other materials will help quartz primer. These products with good adhesion properties are selected by composition, applied to the surface in several stages. Very important is the right choice and compliance with the stages of the process.
Varieties of primer with quartz sand
In the wizard using one of the three types of adhesive material. The first group includes compositions based on synthetic resins and quartz sand. They differ:
- safety due to the absence of solvents and other harmful components;
- possibility of use for decorative finishes - the addition of a coloring pigment is allowed;
- universality of application inside and outside buildings;
- minimum consumption - no more than 300 g of material is needed per 1 m2.
Quartz primers based on resins of synthetic origin can be applied to the surface at a temperature not lower than + 5 ° C. The warmer, the faster the composition dries.The average setting time is 5 hours. This material is often referred to as primer paint, but it is not suitable for topcoat.
The next option includes acrylic resins and latex. Such a quartz primer perfectly tolerates fluctuations in temperature and humidity, has a high vapor permeability and water-repellent properties. On consumption, this type of adhesive composition does not differ from the previous one. Only the price of primer with acrylic resins is much lower.
The third category is silicate primer with quartz. The base of liquid glass allows you to perfectly fill all cracks, correct defects, irregularities on the surface of the walls. Soil is easily combined with different coloring pigments to expand the scope of its operation. This version of the composition is excellent for working in rooms with high humidity levels. Silicate primer is often used for work in basements. It is recommended to apply the primer on the wall at a temperature above + 7 ° C. The silicone-based compound has two serious drawbacks - a long drying period of 12 hours and the highest cost on the market.Therefore, repair and finishing teams often choose other options primer.
Tool preparation and application steps
Special roller or paint brush - the main working tool. For processing small in size, but hard-to-reach areas you can take small narrow brushes. It is recommended to use a drill and goggles to mix the compound to avoid getting the primer in the eyes. Frozen surfaces can not be processed immediately - they must be completely thawed for optimal results. To do everything right, you need to adhere to the correct sequence of actions. All work is divided into five main stages:
- thorough cleaning of the surface (base);
- removing the old coating;
- primer preparation;
- direct application with a roller or brush;
- finishing walls.
At the first stage, all types of pollution are eliminated. Sometimes the surface is washed with water. For further preparation of the walls, you can use a damp cloth, vacuum cleaner. The old coating is usually removed with a stiff metal brush. Next is the preparation of the composition - with a drill and mixer, the soil is stirred until the components are completely connected to each other.It is advisable to repeat the procedure every 20 minutes, since the dissolved particles of quartz will settle.
After receiving a thick consistency of the material, you can proceed to the main work. Quartz primer is applied quite quickly, especially if there is a coloring pigment. For these actions, professionalism is not required - if there is a qualitative composition and a suitable tool, everything will turn out perfectly. Usually it is not necessary to apply several intermediate layers of adhesive material. After processing the walls it is recommended to wait at least one day. Then you can proceed to further facade decoration.
Nuances and tips
The primer with quartz sand in the composition is optimally suited for subsequent work with lime, gypsum, cement plasters, wood and ceramic surfaces, which are given a roughness for perfect adhesion. This material is not recommended to be applied using a spray gun, although inexperienced repairmen use this option to simplify and speed up work. The aerosol will not allow to achieve the desired level of surface roughness of the walls, but the nozzle can clog.If you see that the layer of plaster exceeds 5 cm, use serpyanka tape
Some experts believe that a simple cleaning of the surface will not be enough and they advise you to thoroughly degrease the walls before applying the primer and further finishing. When choosing the composition it is recommended to focus on the level of consumption and decorative properties of the product. Quartz primer is not suitable for processing plastic and metal surfaces, as they do not have the ability to absorb liquids. After drying, the sand will quickly be on the floor. It is not recommended to use this material for treating walls that are exposed to strong UV rays. The sun has a detrimental effect on quartz-priming mixtures. They are not suitable for processing ceilings.
Experts believe that it is best to use a quartz primer, if you need to get rid of minor defects, reduce the cost of finishing, form a half-transparent surface. The use of this material opens up unlimited possibilities for decorating the facades of buildings inside and outside.But while working outdoors it is worthwhile to fear precipitation. Raindrops falling on the walls can ruin all the work. Therefore, it is better to postpone it to increase the dry air.
