An epoxy scraping layer is indispensable when applying a self levelling floor (epoxy or polyurethane). In this article you read everything you need to know.
A scraping layer is a composite layer with which substrates such as concrete and sand-cement screeds can be leveled and made liquid-tight. This layer is applied after an epoxy primer and before an epoxy or polyurethane self levelling floor.
The advice is to first apply a primer and then apply the scraping layer. However, in practice we see that the scraping layer is applied directly to the substrate, making it a replacement for the primer. Only when the surface is extremely absorbent a primer is used.
Because a scraping layer is never used as a final layer, it is difficult to demonstrate examples in practice, but you can be assured that a scraping layer is applied below 60% of the composite self levelling floors.
The scraping layer is delivered unpigmented. However pigmentation is possible on request.
Although the scraping layer is usually finished with a self levelling floor, it is also possible to finish it with 1 or 2 layers of HIM coating.
Why use a scraping layer when applying a self levelling floor? The main reasons are:
HIM produces two scraping layers: HIM RAG-N1 and HIM SL1000. Both are suitable for epoxy and polyurethane floors. A number of advantages:
In connection with the reaction speed, we advise you to use HIM SL1000 in the summer period and HIM RAG-N1 in the winter.
