How to Apply an Epoxy Floor

A guide to the key steps involved

In this article we cover the basic steps on how to apply an epoxy floor. This guide covers a broad and general approach and should not be treated as the only acceptable procedure for applying an epoxy floor. Every flooring project is different. Conditions prevailing in each situation (substrate, temperatures, humidity and needs of end-user) differ significantly from project to project.

Step 1. Is the preparation of the surface. The purpose of surface preparation is to provide a clean surface with the proper mechanical grit that allows both mechanical and chemical bonding. There are different methods recommended such as grinding or shotblasting. When applying thin coats you should use a less aggressive method.

Step 2. After having ground the surface it is important to vacuum and clean the surface from all the dust. If the dust is not collected, this will lead to debris getting trapped in the coating. Furthermore bonding between the epoxy and the substrate will be weakened.

Step 3. The next step is the application of the primer. We recommend Ktisepox Hydro PR for most applications. If you are dealing with areas that rising dampness we recommend that you use Rapidcure Primer instead. Priming is a very important step that should not be overlooked. Priming enables the penetration of the substrate so that the floor is ready to accept the new epoxy coating. Furthermore the use of primer helps seal the floor and reduces the chances of bubbling. If the substrate absorbs all the primer, we recommend that a second coat is applied.

Step 4. Most floors will have some cracks or holes. Therefore we recommend  Ktisodur G to close all the cracks and fill all the holes that are present

Step 5 involves applying the base coat (or base coats) . Depending on the epoxy floor being applied you may have one base coat, several layers or in some cases the base coat is skipped and just a topcoat is applied. In multi-storey car parks , we tend to apply an intermediate elastic waterproofing layer before applying the topcoat.

One of the benefits of applying a base coat is to get a better feel for the floor and get an idea how the final floor will look like. The base coat can bring out any existing anomalies or uneven spots. This is a crucial step before applying the topcoat and corrections will no longer be possible

Step 6 involves the topcoat. Depending on the floor system in question, the topcoat can be either an epoxy coat like Ktisepox or a self levelling floor like Ktisofloor. If you need fast curing floor choose Rapidcure Floor.

If applying outdoors apply Ktisopur UV as a topcoat. You can watch a video on Ktisopur UV here.
