Day 1 Start

It all starts with a good substrate. The substrate should be level and even, and also completely clean and dry. The moisture content is checked. A slight roughening of the substrate with a sander will improve the adhesion of the first layer.

The next step is the primer. The primer allows a good adhesion of the casting floor to the substrate and strengthens the substrate.

Days 2 and 3: Resilient base mat or scraping layer

An option for extra comfort is a resilient base mat. Its advantages are: reduced impact sound and less chances of cracks.

The sequence is this: Glue >> resilient base mat >> sealing layer >> insulating layer

In case of a standard casting floor only a scraping layer is applied. The scraping layer realises a fully smooth, even and sleek substrate. It also fills possible unevenness’s. When the scraping layer has dried completely, the floor is ready for the next layer, the casting floor.


We developed the EPI Superbase casting floor with a special crack-bridging membrane, which replaces the resilient base mat. This membrane absorbs 99% of all cracks, which means that this solution enables you to opt for security. This combination also reduces the impact sound by 15 dB! Please read more on the EPI Membrane here.

Days 3 and 4: Application of the casting layer

This is the layer that really determines the look of your floor. In this step, the casting layer is levelled out with a skimmer on the substrate. The occupants of the house in the time-lapse shot have chosen the super strong, non-yellowing EPI 600-NV floor in the EPI colour “Glow”. This is a so-called blend: a concrete-look casting floor, which consists of a mixture of two colours.

Day 5: Finishing

To finish the floor, one or two topcoats are applied. This protects the casting floor and gives it a beautiful finish.

That’s it! Enjoy your floor.
