Hi All I am considering staining the concrete or maybe even using some of the new epoxy treatments, The room I want to treat has carpet in it now and yes the previous owners dogs used it as a bathroom. Can one stain concrete over this problem? My other main question is how does one deal with the transitions. In the entry way there is ceramic tile and in the kitchen there is vinyl. Is there any way to do this and make it look right except for tearing out the ceramic and removing the vinyl? Thanks for ur help.
