Q: Can oil modified urethane be used to recoat over Swedish (Glitsa) finishes?
A: If it is a fully cured finish there shouldn’t be any issues – provided the Swedish finish is fully cured.
Related Q: I recently had #3 grade (wanted the character) red oak flooring installed. We filled with black grout to give the character. The installer used “G*****” Swedish finish. We were told, after the fact, that the finish does not seal the grout (knowing this, we would have checked into options). I just need to know if there is a sealer that we can use over the top of G***** to re-seal everything? Your help is greatly appreciated!
A: I haven’t used acid cure G***** in many years. It was so nasty to work with. Tough finish though. It is my understanding you can apply anything over it but you can’t apply G***** over anything. So, you should be good to apply another finish over it. I would be sending an email to the company and also asking the floor company that did your floors.by
