To ensure the best adhesion of building mixtures and finishing materials to various types of surfaces, it is recommended to use a primer with special properties. High-quality concrete contact primer is a sure guarantee of durability and maximum strength of the finished finish. With all its advantages, this material does not require special skills and sophisticated tools - a regular roller, airbrush or a convenient brush can be used to apply it.

Features and differences from other types of primers
The most important difference between a concrete contact and other existing primers is its special composition, which includes:
- quartz filler of a sufficiently large fraction;
- styrene-alkylate dispersion as a binder component.
Each of the components of this tool complements each other. Styrene provides a perfect bond with smooth glossy surfaces, and coarse quartz sand creates the characteristic roughness necessary to improve adhesion with those materials that are based on cement.
The high-quality adhesive primer concrete contact is distinguished by special properties that provide it with wide universal application in modern construction and repair work.
This type of primer is indispensable when performing both internal and external works. It is used when proceeding with the device of concrete screeds and bulk floors.
It also plays the role of a very strong and reliable foundation before the subsequent coating of surfaces with putties or plasters of any kind.
Due to its versatility, this tool is able to be applied very easily and hold firmly on almost any kind of surface:
- brick;
- reinforced concrete;
- drywall;
- ceramic;
- asbestos cement;
- coated with alkyd or oil enamels.
Numeric data
For primer concrete contact, designed for indoor and outdoor use, the following technical characteristics are characteristic.
- As a rule, it is produced in packages of 3, 5 and 14 kilograms.
- The size of the fractions of quartz particles that make up this product can vary from 0.63 to 1.25 mm.
- The consumption of this type of primer is quite economical. Depending on the level of porosity of the treated surface, approximately 200 to 350 g of this primer may be required per square meter of area. The average rate of consumption of concrete contact is 300 g per square meter.
- As diluent, ordinary water is used.
- Many are interested in how much the concrete contact primer used for outdoor work dries. The average drying time at an air temperature of +20 degrees Celsius is from two to four hours.However, in some cases, subsequent finishing work is recommended to be carried out after at least 12 hours have passed since the application of the primer.
Due to its technical characteristics and special composition, concrete contact is very much appreciated by professional builders.
For this tool, the following important points are characteristic:
- Significant durability - the primer from world famous manufacturers does not lose its properties for 70-80 years;
- excellent waterproofing properties - as this composition dries, it forms a characteristic waterproof film on the surface;
- drying speed - in most cases, this tool dries only two to three hours, after which you can begin to perform further external or internal work.

Consumption
People who are planning to use a concrete contact for the first time are often interested in how much money is required to successfully carry out outdoor or indoor work.
The average standards specified in the instructions for this composition vary from about 200 to 400 g of the product per square meter of surface to be treated. However, in reality, how much the consumption of this primer will amount to may vary in a particular case, since it depends directly on the quality and type of surface to be coated.
On too porous concrete surfaces, as well as on the surface, early coating with cement-sand plaster, this composition is best applied not in one layer, but in two. Of course, you can only use high-quality primer, which has a certificate of conformity.
to contents ↑The right choice and application
The use of the popular primer concrete contact must be carried out in accordance with all the rules. First of all, you need to choose the right material - give preference only to reliable and well-known manufacturers whose products have the appropriate certificate. Only in this case can you count on a result that will delight you for many years.
Before applying the finished composition, properly prepare the surfaces. For these purposes it is necessary:
- remove all dust and dirt, as well as exfoliating elements;
- cover the surface with a layer of ordinary primer;
- wait for the treated surfaces to dry completely.
After this, you can start applying the concrete contact. Containing large particles of quartz sand in its composition, this tool is best applied with a wide brush - this will ensure a uniform layer. A quality, certified product is easy to apply, ensuring perfect grip due to its high technical characteristics.
If you are interested in how much money is required to provide the best coverage, keep in mind that its expense is usually quite economical. A primer with a certificate is applied per 1 sq. Km. a meter of surface on average in a volume of 300 ml - this amount is enough for an ideal coating.

A reliable concrete contact primer dies quite quickly - usually from two to five hours. However, here you need to take into account some nuances. If no more than one hour has passed since the application of the composition, and it seems to you that the surface has completely dried up, it is better to play it safe.
It is easy to check the condition of the coated surface by drawing a spatula made of metal on it. So you can make sure that the surface is not yet ready for further finishing. The minimum drying period for a quality concrete contact is two hours.
But before carrying out subsequent work it is better to wait a little more time.True, it is undesirable to delay with them - too long a break will cause dust to begin to accumulate on the surface, and this, in turn, can adversely affect the quality of adhesion.
The composition of the concrete contact is carried out at a temperature not lower than + 8 ° C. If there are problematic places prone to cracking, it is better to apply an additional layer of the agent to them. For best results, use only a high-quality primer with the appropriate certificate. Knowing what the consumption of this product should be and how long it dries, you can get the best coverage of walls, ceilings, floors or other surfaces.
The use of high-quality concrete contact is an important step in the processing of any surfaces. The optimal composition helps to level and strengthen the surface, and also provides the best adhesion to any kind of mixtures intended for further finishing work.
