ᐅ Epoxy resin floor on concrete screed

Hello,

we are considering covering the concrete screed in our house with epoxy resin to achieve a concrete-look floor through the epoxy.

Does anyone have information about the cost per square meter (without screed, as that is required anyway)?

Are there any significant disadvantages?

Thank you very much for your answers.

Be sure to inform the screed installer in advance that you want to lay this type of flooring.

P.S. I have this kind of floor in my garage. In living areas, it would feel far too cold/uncomfortable for me.

We were warned about epoxy resin because it is difficult to accurately assess how harmful the fumes can be to health. Since we have a small child, this was absolutely unacceptable for us.

I once asked a floor installer about this. For private customers, you probably have to expect around €45 per square meter (about $48 per square yard). Industrial floors— I asked about this when they installed it in the office—can be obtained from around €12 per square meter (about $13 per square yard). However, that was likely for an area of 2000m² (21,500 sq ft).

If you have chosen a specific type, I can inquire there again.

Hello everyone, does anyone have experience with an epoxy resin / polyurethane resin coating on screed concerning
- Application
- Appearance
- Long-term behavior (streaks, dents)
?
I would like to use this in the basement as a thick coating. Not painting/rolling, but rather pouring it out and then spreading it with a squeegee to level out smaller unevenness.

Hello One

Have you applied a coating to the floor in the meantime?
Could you share your experience?


Thank you

Hello "dergiss".

First of all: the term "Betonestrich" does not exist. The differences between concrete and screed are numerous, ranging from the differing installation techniques to the aggregate used. But that is not the topic here.

Do you have a residential building? Then you absolutely cannot do without a screed as a load distribution layer. Where – please – would the insulation layer for effective thermal and/or impact sound insulation be installed?

An epoxy resin coating does not automatically result in a concrete appearance.

Also, please do not forget the necessary subfloor preparation measures to ensure that the coating application is not only expected but also successful.

In this context, the term "emissions" came up from another source. Just as a note, only synthetic resins that have successfully passed the AgBB evaluation scheme for building products are approved for use in living areas!

No, I would structure it differently (from bottom to top):
- Concrete ceiling or slab, the latter, of course, with waterproofing according to DIN 18195-5 (German standard for waterproofing)
- Thermal insulation on the ground floor and impact sound insulation on the upper floors
- PE foil as a cover layer
- Cement screed CT-C35-F6-S45 with the note that a synthetic resin-based sealing will be applied on top
- Scratch coat (optional)
- Pigmented seal or better: industrial filler with concrete look and final sealing

------------------------------------

The costs for a synthetic resin sealing with prior scratch coating should be around €60/m² (net), and for a decorative filler (which was not mentioned here) about €95/m².

PS: With €12 to €45, dissatisfaction is already programmed, because your expectations regarding the floor’s appearance and durability will certainly not be met. The cost estimate lacks the (complex but necessary) preparation measures for the subfloor!

Best regards, KlaRa
