Epoxy resin floor and cove fillet

Hello everyone,

I am new here in the forum and would like to briefly introduce myself. I am 36 years old, from southern Germany, and am currently renovating our house, built in 1969.

At the moment, I am working on renovating the basement. We have excavated the entire old concrete, paving, and natural ground. Then a new floor slab was poured (10-15 cm thick) and connected to the foundation with steel bars. On top of that came a Katia foil as a vapor barrier and then a concrete screed (industrial quality). The individual rooms and the walls were separated from the screed by impact insulation strips.

Now I want to shape a cove with epoxy resin on the wall and then coat the entire floor with epoxy resin.

I have already heard that the cove can/should be applied on the edge insulation strip. However, I now have the problem that the edge insulation strip and the wall covering of tiles are already flush and I do not want the cove to protrude. In addition, the edge insulation strip is damaged in some places due to the grinding of the concrete.

Can I cut off the edge insulation strip and apply a new strip to separate the cove + floor and walls (with less thickness) so that the cove is flush with the tiles? What material should this strip have so that the epoxy mortar adheres well?

Can the strip be glued to the wall, and if so, with which adhesive?

Or do you have completely different suggestions? I would be very grateful for your tips!

Many greetings
Bulli

Insulation strips must be cut down at least to the screed level, apply a fillet with acrylic, resin over it.

Hello cuckoo,

thanks for your answer, does that mean I apply the fillet (5cm high and 5cm deep) entirely with acrylic? Can you then also smooth it off with such a fillet trowel? I thought this is done with a mixture of quartz sand and epoxy resin as a pre-formed fillet.

Why should it be 5cm? Is that really your intention? Just make an acrylic joint there like with a tile baseboard, which you simply paint over with the resin.

The variant with sand and resin is unknown to me, which of course doesn't have to mean anything.

This should be waterproof and easy to clean, as food is to be processed in this room (honey). The room also has a floor drain and a connection for a water hose.

That represents the resin, applied in multiple layers, yes, certainly. The tiles on the wall as well. Is it not possible to simply tile all the way down, seal the screed, and make the wall connection "conventionally"?
