Ensure that the concrete is structurally sound. If you want to obtain durable results with your new epoxy flooring, the first step is to check the state of the floor. A reliable epoxy flooring contractor will test the concrete and determine its condition. One of the most common tests is water vapour transmission; too much water in the concrete structure prevents proper coating adherence.
There are two main types of concrete, hard and soft, as well as rain affected. With this kind of concrete, the slab was poured either in rainy conditions or the concrete was affected by rain before it dried. Slabs need to be tested before you coat over the top, as hydrostatic pressure can literally blow the coating off.
Clean the floor. This stage is compulsory before installing any type of floor. Vacuum up any dirt and dust to clear the surface and ensure perfect adherence of the new flooring.
Choosing the right type of diamond for grinding or shotblasting. Another important aspect to keep in mind with floor preparation for epoxy flooring is to ensure a proper diamond grinding or shotblasting of the concrete.
Ensuring levelling and flatness. Levelling and flatness are two different things, but they are achieved at the same time. Getting a substrate level and/or flat can be very costly but it is required for obtaining good results.
Patching holes and cracks in concrete. Prior to installing epoxy flooring, you will often need to patch holes and cracks using a variety of appropriate products.
