A versatile primer called concrete contact is applied to smooth, non-absorbent surfaces to enhance the adhesion of new plaster or concrete. Finding out how much concrete contact you’ll need is crucial, whether you’re building a new project or remodeling your house. By accurately estimating the quantity, you can be sure that you will have enough to cover your surface without wasting any.
Although it may appear difficult, figuring out how much concrete contact is consumed is actually very simple if you know the important details. These consist of the kind of surface, its state, and the particular product you’re utilizing. Each of these factors affects the amount of primer required to form a solid, long-lasting bond.
We’ll take you through a step-by-step procedure in this article to help you determine how much concrete contact your project will require. Knowing these fundamentals will help you plan more efficiently and save yourself the trouble of running out of supplies in the middle of a project or having too much extra. Together, we can successfully complete your next project.

Where it is used?
It should be noted that the composition allows it to be applied to a wide range of mixtures. This includes different tiles, walls, and ceilings made of concrete. Furthermore, this material is essential for covering a building with decorative plasters for its facade. Concrete contact can successfully perform its designated functions on any surface, both indoors and outdoors.
How to calculate?
Concrete contact can be applied to any surface, not just walls made of concrete. Please be advised that depending on the kind of surface it is applied to, certain wear characteristics may change. For instance, it is one thing to work with concrete walls, but quite another to work with brick or plasterboard.
Let’s partition the surfaces based on the parameter of porosity. These surfaces can be divided into three categories.
- Porous – these include brick, sand and sand concrete. If you are working with these materials, use approximately 0.3 – 0.5 kg of concrete sealant per m2. In addition, if the surface has high porosity, it is necessary to treat it with special deep penetration waterproofing materials.
- Medium porosity – this can be cast-in-place concrete, concrete tiles or self-leveling flooring. Dose per 1 m2 is 0.2 – 0.35 kg.
- Low porosity materials such as ceramic tiles, troweled concrete or paint. About 0.15 – 0.25 kg of material is enough.
What else does consumption depend on??
Much more primer will be needed if the treated walls absorb water well. It is noted on the packaging by the manufacturers that 300 grams of primer are needed for every square meter. However, in practice, this number rarely matches the given one, and the concrete putty ratio has unique properties of its own.
One must use a device known as a sampler to determine the approximate amount of primer required. You will need to choose a 1×1 meter square and apply a specific quantity of solution to accomplish this. Weighing the mixture and the container it is in is necessary. Concrete contact can then be applied to the surface. Verify that the mixture holds tightly at the conclusion of the work, and make any necessary corrections.
The solution can be weighed once more once the entire space has been filled. Your surface’s coefficient of consumption will be determined by the difference between these figures. It is important to remember that this test square should be filled in evenly, smoothly, and without any gaps.
Sand and cement will crumble if the solution is insufficient in some areas. It is preferable to apply a second layer in such circumstances, typically requiring 20–30% less primer.
How to reduce solution consumption?
It is best not to ask this question at all because concrete putty has the unique quality of not being too expensive to save and reduce consumption. Lower consumption might lead to much less durability; the coating might start to peel off completely and crack.
Adhesion, or the interaction between the base and the new coating, will likewise decrease if the amount of contact with concrete is reduced, but even this is not the worst scenario. Recall that one of the functions of a concrete sealer is to provide waterproofing.
Since many coatings that react with the primer are based on Portland cement or gypsum, water is required to dilute them. The coating will start to dry out if the water evaporates from the mixture too soon. Since this keeps the primer from coming into contact with the concrete, it is best to abandon the idea of calculating the primer in order to save even more money.
How to prepare the surface?
Consumption is dependent not only on the surface but also on how well the surface is prepared prior to work. The work area must first be cleared of debris and dust. It is preferable to get rid of any areas that have started to peel or crumble right away. Plaster should be used to seal any existing irregularities.
Concrete contact has the characteristic of not adhering to greasy surfaces. If such areas exist, it is best to clean and degrease them before moving further. Paint-contaminated areas can be cleaned with a moist sponge; if this isn’t feasible, it’s preferable to apply a basic primer over them. Because the primer fills in cracks, this process helps to significantly reduce wear.
To guarantee that the concrete sealant sticks firmly to other materials, remove any tiny debris at the conclusion of the processing.
| Step | How to Calculate Concrete Contact Consumption |
| 1 | Determine the area to be covered. Measure the length and width of the surface in square meters (m²). |
| 2 | Check the manufacturer"s recommendation. Find out the coverage rate of the concrete contact, usually given in liters per square meter (l/m²). |
| 3 | Calculate the amount needed. Multiply the area (m²) by the coverage rate (l/m²). For example, if the area is 50 m² and the coverage rate is 0.3 l/m², the amount needed is 15 liters. |
| 4 | Account for waste. It’s good to add around 10% more to cover spills or uneven surfaces. So, for 15 liters, add 1.5 liters extra, totaling 16.5 liters. |
| 5 | Buy the right amount. Round up the total to the nearest whole number and buy the amount needed. For instance, you’d buy 17 liters to be safe. |
To guarantee that your project operates smoothly and effectively, you must calculate the consumption of concrete contact. You can prevent needless costs and make sure you have enough material to finish the job without interruptions by precisely estimating the amount required.
Measure the surface area that needs to be covered first. In order to calculate the total area in square meters, measure the length and width of each wall or surface and multiply the results. Remember to deduct the areas of any windows, doors, and other openings from the total in order to account for them.
Next, take into account the coverage rate recommendations made by the manufacturer, which are typically listed on the product packaging. You can calculate the amount of concrete contact required per square meter using these rates. To find out how much concrete contact your project will need, divide your total surface area by the coverage rate.
Always remember to purchase a little extra in order to cover any errors or uneven surfaces that may call for additional product. This guarantees that you won’t run out of resources in the middle of a project and experience delays. You can guarantee the success and cost-effectiveness of your project with thorough planning and precise calculations.
In order to guarantee appropriate adhesion and durability in building projects, it is imperative to calculate the consumption of concrete contact. The surface area that needs to be covered, the kind of substrate, and the recommended coverage rate from the manufacturer should all be taken into account when calculating the appropriate amount. By precisely measuring these components, you can determine how much concrete contact will be required, cutting down on waste and guaranteeing a solid, long-lasting bond for your building project.
