The above picture is of a garage floor with a Concrete Surface Profile or CSP. The drops of coating on top of the floor are designed to help you understand what surface tension looks like. There are two drops of resin on top of the floor that are in a bead and, there is one drop that has been broken with a finger. Resin does not naturally want to penetrate the surface of concrete because of something called surface tension. Surface tension keeps the epoxy in a bead instead of soaking into the concrete. Surface Tension is the enemy and must be overcome. Grinding concrete before applying a coating creates more surface area which makes braking the resins surface tension easier, but it does not do the job for us. A floor coating installer must use physical energy and sheer force to roll the primer coat of resin into the porous surface of the concrete. Using energy to overcome the surface tension in the concrete and in the resin is vital for success. Alternative methods of applying a primer such as squeegee or spray application will not brake as much surface tension as rollers will because mashing the coating into the pours will force the coating into the holes and crevices more effectively than squeegee or spraying. The two drops of coating to the left will easily peel after they dry because they are on top of the concretes surface and not trapped deep inside of the concretes pours. Garage floors have air pockets and are oily and contaminated in nature, so it is critical to push the coating into the crevices and past the contaminants that are in the pours of the concrete to ensure that the coating goes as deep as possible for a strong grip.

The above picture is of a concrete garage floor that was properly installed. The concrete is smooth because the installers used a trowel to make it smooth when they installed the wet cement. Using a trowel to smooth the top surface of the cement is the correct way to install concrete in a home or garage. Unfortunately glue will not stick to a smooth surface, so we must profile (rough up) the concrete some how so that the coating will have something to grip onto. Just like a rock climber needs rocks to grip onto the coating needs rocks to grip onto in order to stay stuck to your floor. The floor below is after the concrete surface has been profiled with a diamond grinder. Diamond grinding is one method of profiling a concrete surface. The floor below has a Concrete Surface Profile because it is not smooth anymore. A Concrete Surface Profile is what you get after you prepare concrete and expose the rocks and roughness below. A Concrete Surface Profile is the degree of roughness on an otherwise smooth surface. If a CSP is not created then the epoxy will have nothing to grip onto and the floor coating will eventually peel or buckle up from the floor because it was unable to grip onto it.
