How to apply concrete contact for paint, whitewashing or putty: work rules

It is imperative to apply concrete contact prior to painting, whitewashing, or puttying in order to guarantee optimal project outcomes. Concrete contact, sometimes referred to as bonding primer, aids in producing a rough surface that improves the adhesion of layers that follow. This easy but important step can have a big impact on how well-finished and long-lasting your work is.

It’s crucial to set up your workspace and gather all the required supplies before you begin. A spotless surface, high-quality concrete contact primer, a brush or roller, and the proper safety equipment are required. Making the necessary preparations now will spare you from problems down the road.

Thoroughly cleaning the surface is the first step. Eliminate any loose particles, dust, or dirt that might impede the bonding process. To guarantee that the primer adheres well, the surface must be dry and clean. Applying the concrete contact can start as soon as the surface is ready.

Apply the concrete contact uniformly all over the surface using a brush or roller. Ensure that every area is evenly covered to prevent any weak points. Follow the manufacturer’s instructions and let the primer dry completely. In order for the primer to form a solid bond with the surface, this drying period is essential.

After the concrete contact has dried, you can start painting, puttying, or whitewashing. The primer will give your finish a flawless, polished appearance by creating the perfect foundation. You can give your project a high-quality, long-lasting outcome by following these steps.

What is concrete contact

Concrete contact is a priming mixture that includes water, styrene-acrylic dispersion, dye, filling, and extra ingredients to enhance properties.

A specific granulometry indicator added to the filling component determines the composition’s uniqueness.

For filler in less expensive types of mixtures, foreign companies typically use quartz sand instead of marble flour. It should be highlighted that adding or removing fillers does not significantly alter the product’s technical properties; the end product is still of excellent quality.

Purpose and features

In order to respond to the query of whether concrete contact paint can be applied, you should research the product’s capabilities. After drying, the primer layer has a coarse appearance and good moisture resistance. Apply the product while keeping in mind the stated purpose on the packaging. Thus, options for putty and plaster exist.

Among the primer’s characteristics, the following stand out:

  • You can apply a layer to horizontal and vertical bases, the layer will help increase the surface adhesion parameter;
  • The solution is with good resistance to humidity, for this reason it is often selected for the waterproofing layer when laying floor materials;
  • The coating dries on average in 4-6 hours, the duration of the process is affected by moisture and temperature indicators in the room. When there is increased humidity, then let the layer dry at least a day, also work outside the building;
  • Durability, professionals say that if the processing technology was carried out correctly, then the coating will retain its properties for 80 years;
  • The application of the primer passes simply, you can use rollers, brushes, or other suitable devices with the tool. The ease of distribution of the layer allows beginners to work independently, but experts also often choose concrete contacts.

Among the compound elements are:

  • Acrylic dispersion, which is necessary to obtain better adhesion of materials;
  • Quartz sand, which is responsible for the rough structure of the coating;
  • Cement mixture;
  • Chemical additives that contribute to increasing other characteristics, moisture resistance, strength, resistance to external factors.

Since the primer contains no hazardous materials, it is regarded as environmentally friendly.

Moreover, biological formations can be avoided by using bactericidal substances. Because the tool is regarded as neutral-acid, you can use it with lime and it won’t cause corrosion processes. Dye is applied as needed to make the treated surface visible.

What can be applied to concrete contact

Prior to additional finishing tasks like adhering wallpaper, applying enamel and other paint materials, and t.P., priming is done. The following are notable among the application areas:

  • Processing of concrete, brick, cinder blocks;
  • Coating of drywall sheets to reduce porosity;
  • Glossy grounds;
  • Ceiling processing before whitewashing.

It is appropriate to have a tool for both inside and outside the building. After plastering and puttying, you can use this material to apply the base; concrete contact with oil paint allows you to avoid having to go through a laborious paint removal process.

Paint (under tiles, under wallpaper, oil paint)

Ignorance of the primer’s characteristics leads to the use of concrete contact for oil paint on tiles. Even though oil paint is tough, the solution grows well with the base; however, the layer does not always hold the tile material in place.

Its application prior to tile installation is advised in cases where the base exhibits poor hygroscopicity and low adhesion, traits typical of a gypsum base (such as plaster). In other cases, selecting the standard primer will suffice.

Installing tiles on top of tiles is occasionally an option; typically, this involves cutting a notch and using a grinder to remove glaze, but this primer can help cut down on labor.

When using wallpaper, it is important to consider the pinkish hue of the solution; if the finish is light, wallpaper coatings may bring out the color.

It is recommended to use it prior to tile installation if the base exhibits poor hygroscopicity.


Can concrete contact be used with putty finish? The response will be affirmative, but if the base is level and alignment is not required, then fix any imperfections. It is much easier to repair if you apply it over oil paint because removing the previous layer is challenging.

After grinding, it will be necessary to remove the ready-to-fall-off paint layer, notch the entire surface, and clean the base prior to priming.

Concrete tape is also utilized for whitewashing, following an initial cleaning of dirt and poorly maintained components. After fixing any base flaws, apply a primer solution—which has deep base penetration and is excellent for whitewashing—to finish the job.

The longevity and quality of paint, putty, or whitewashing on concrete surfaces depend on the proper application of concrete contact. Before adding the next layer, the surface must be completely cleaned, the concrete contact must be applied evenly, and it must be given time to fully dry. This initial stage of preparation guarantees improved adherence, inhibits peeling or cracking, and produces a polished, seamless finish. You can give your concrete surfaces a durable and attractive finish by adhering to these few guidelines.

Features of the use of concrete contact on a surface covered with paint for subsequent plaster

You must carefully examine the surface and remove any paint layers that have already started to fade if you want a high-quality outcome. Prior to applying a layer of primer with a brush or roller to a dry surface, a smooth and clean base must be achieved.

The solution has a shade that allows the unprocessed zones to be seen. If necessary, two layers can be applied, and each layer dries for three to four hours. The following types of work can be completed 24 hours after the primer is finished.

Adhesion to various, even complex bases can be increased by concrete contact of a primed mixture, which is released by deep penetration. The solution is simple to use, allowing you to perform manual repairs.

Step Description
1 Clean the surface from dust, dirt, and old coatings.
2 Ensure the surface is dry and free of grease.
3 Apply a primer to improve adhesion.
4 Mix the concrete contact thoroughly before use.
5 Use a roller or brush to apply the concrete contact evenly.
6 Let the concrete contact dry completely, usually for 2-4 hours.
7 Once dry, proceed with painting, whitewashing, or applying putty.

The application of concrete contact is an essential step in painting, whitewashing, or puttying to guarantee a long-lasting and superior finish. It offers a robust layer of adhesive that improves the final coating’s bonding to the concrete surface. This procedure aids in the prevention of peeling, cracking, and other typical problems brought on by inadequate adhesion.

It’s crucial to correctly prepare the surface before beginning. To do this, give it a thorough cleaning to get rid of any dust, oil, or loose particles. A spotless surface makes it possible for the concrete to adhere to the surface and provides a strong base for the paint, putty, or whitewash layers that follow.

For even coverage, use a brush or roller when applying concrete contact. Observe the directions provided by the manufacturer regarding application methods and drying times. When applied correctly, the concrete contact creates a consistent, tacky surface that enhances the adhesion of the subsequent layer.

You should wait for the concrete contact to completely dry before painting, whitewashing, or puttying. To guarantee that the final coat adheres correctly and lasts longer, this step is essential. A more polished and durable finish will result from this process’s patience and accuracy.

In conclusion, while using concrete contact may seem like an extra step, it greatly improves the project’s quality and durability. You can guarantee a beautiful and long-lasting result with paint, putty, or whitewash by following the right procedures and allowing enough time for drying.
