Artificial resin floor too soft? Dents and color stains

Hello everyone,

A few months ago we bought a house that has an artificial resin coating on the screed in the living area.

Actually, artificial resin should be resistant. But our floor absorbs everything that falls on it, which leads to discoloration from drops of juice, red wine, or similar, that can no longer be removed. Now we have even noticed that the runner has left stains on the floor. And the flowerpot, which stands on a coaster with wheels, has left dents on the floor through the wheels due to its weight (about 10 kilos).

Our suspicion: Something went wrong during the processing.

If the floor is so soft and permeable, does this affect the wear and possibly the indoor climate (pollutants)?

Does anyone have any idea what can be done?

We have already considered laying laminate on top. But we are not sure if that is even possible or useful.

We would be very grateful for expert advice!

Regards Anna

Hello Anna, according to your description something is really not right. However, as an expert it goes against me to give an opinion from a distance with little information. It really has to be inspected on site, rock assessment, therefore also an expert. Which region are you from? I would recommend asking a specialist company near you for advice. There you can discuss all pros and cons in direct contact. As I said, from a distance it is difficult or impossible. Sorry!

Thank you very much for your reply!

We live near Überlingen on Lake Constance.

Hello Anna-Maria. Discolorations can certainly occur with reaction resin floors in industrial construction, but this is not a material-specific property for residential or commercial areas. Therefore, it should be questioned what kind of system the synthetic resin used in your house is. Transfer of color is certainly not a typical and therefore acceptable property, and dent-like depressions under the described bearing surfaces are also not acceptable with cement screeds (as a coating substrate). Just name the system and material manufacturer! This should be listed on the offer or the final invoice. You are probably still in the warranty period? If yes, send a letter to the contractor; the subject line must include "Mängelrüge". A brief introduction naming the current situation and "Aufforderung zur Nachbesserung" with a (realistic) deadline (let's say 4 weeks after receipt of the letter). Regards: KlaRa

Thank you very much KlaRa for your reply@ Unfortunately, no one from the construction is reachable anymore. The company went bankrupt. We suspect that it is a K2 coating. We would prefer to remove the floor, as we are not fans of synthetic resin anyway. But I have no idea how that should work. I think we will have to turn to a specialist company here after all. Best regards

Well, whether synthetic resin or other coatings: With the exception of wood or mineral surface coverings, we are always confronted with products that are the end result of a chemical transformation process. In synthetic resin materials, there are also variants that, when executed properly by craftsmen, look visually excellent. So one should not completely "put these products in the corner." Well then, how does one remove a synthetic resin coating that (possibly, I don’t know) is not cured? It should not be doubted that it needs to be dismantled. Covering it with other materials is like walking through your own apartment only wearing black-tinted glasses, following the motto "What I don’t see isn’t there!" For smaller (soft) areas, you can work with a scraper, for larger (largely cured) areas, the fine milling machine must be used, equipped with the appropriate dust extraction technology. Surely, after the removal, you will be "eyeing" another coating, which is understandable. The craft company that receives the order will certainly call on a (let’s call it) "sub-contractor," who carries out milling, shot blasting, and maybe even concrete cutting work. All this is certainly not for the do-it-yourselfer with a screwdriver and toy equipment from the hardware store, but undoubtedly achievable for the specialist company with appropriate professional technology.
