Hi, I am looking into getting a bedroom floor refinished. The last time it was done was 1980 and there are some areas that the finish has worn thru. So I have called a few places that have ads in the local paper. I just spoke to one man and I asked him if the finish was water or oil based. He said it was acid based. I have never heard of acid based finish. It is a product made in Sweden and the name of the product is Synteko. He also said that he would put on two coats. It dries in a about two hours. Have any of you ever heard of anything like this? Or if you have any advice on floor refinishing please feel free to inform me. Thanks. Pete
