We love our stained concrete floors, and they seem to be the envy of almost everyone who comes over.
Over the 18 months or so that we’ve lived in the guesthouse though, the floors have worn a bit. The finish coat is wearing thin in spots, and under my office chair, even the stain seemed to have worn off. (We thought is was permanent.)
In researching this, we found out that the finish we used (Polysoy) is no longer the recommended finish. Now there is a new permeating finish Acrisoy. However, Acrisoy can only be used on freshly stained concrete, never over another finish.
But there is also a new coating called Ecofloorz, so we decided to try that.
The spot under the chair really looked bad, pretty much like raw gray concrete, so we decided to try restaining it again with Soycrete first. The results were nothing short of miraculous. The stain took great, and now you can’t even see where the worn spot was.
