Concrete Coating Tips

There are tons of materials that can be used for flooring, but concrete stands out for many good reasons. One of them is its durability. This durability has made concrete the choice of flooring material for garages, commercial buildings, manufacturing plants, warehouse facilities, etc. The durability makes it capable of withstanding all kinds of pressure in terms of heavy machinery, foot traffic, exposure to chemicals, and environmental elements, among many others. 

However, the durability of concrete doesn’t mean it is indestructible. In fact, with all its qualities, concrete is a naturally porous material that will succumb to moisture, deicing salts, harsh chemicals, and heavy traffic if not treated. One way to treat concrete is by coating. The coating has a multifunctional purpose because it protects the concrete wear and tear and decorates it and makes it skid-free. This is why the coating is always advisable. For a coating to be effective, it has to be done right. Here, we highlight tips that work for concrete coating.

Make Sure There Is Adhesion:

When coating, it is important that the concrete is adequately prepared so that the coating materials will bond to it. This usually means cleaning the concrete surface and if a previous coating has been applied, scraping it off as much as possible. You may also test the coating material on a small part of the concrete to determine its adhesion before using it all through.

Clean The Concrete Surface:

For the coating material to bond to concrete, the surface must be clean. Dust particles and grease on a surface will prevent optimal bonding, so you must get rid of those. Ensure your surface is clean and dry as well.

Level The Substrate:

The coating is only a few tens of microns thick when applied. Thus, it will not hide any irregularity in the level of the floor. This is why you must make sure you correct all irregularities beforehand. You don’t want bulges and protrusions on your floor before coating it because those places are weak points where the coating would begin to wear out way before they should.

Ensure You Have Great Environmental Conditions:

If you are using water-based coatings, you will need to have a room that is at the right temperature and humidity for the coating to bond well. An excellent drying process is essential so factor this into your plans. Make sure the room you are coating has excellent ventilation too.

Apply Evenly:

The best coatings are the ones done without any streaks. So, ensure the application is even. You can use cross-rolling to structure the floor accordingly, and you should also merge the new coating with the parts that were applied before when it is still wet to prevent visible roller marks.

Apply an Extra Layer Where the Surface Is Porous:

If the concrete is untreated, it would be porous. You should therefore apply an extra layer. The first layer might be minimally diluted with water. It also helps if you apply primers first before the coating in such instances.


Getting your coating right will save you money and the stress of maintenance and repairs. All you have to do is make sure the process is thorough and detailed. For more tips and tricks visit
