All I want to know is, is it ok to apply a floor stain on top of an existing floor stain (there is no finish at this time) and then add the 3 top clear coats which will be water base. Or will this jeopardize the quality of the floor (ie cause peeling etc) down the road? The stain product used was Duraseal 50% Weathered Oak and 50% Dark Walnut. The stain that would be applied on top of that is that same product (the 50/50) as option one and for option 2 it would be just Dark Walnut that goes on top of the 50/50. Note: the 50/50 mix was applied last Friday. So the only thing on the floor at this time is just the stain color. All stain colors mentioned above are Duraseal.

Ok thanks. Definitely don’t want it to peel. But, we’ve paid a lot to NOT get what we asked for. And, went about selecting the sample in the way they advised. So not sure about moving on. Will follow up w GC.

I suspect the sample and the main floor were treated differently. Sample area was hand sanded to a different grit than the main floor, or they let the stain sit longer on the sample than they did the main floor. Blotchiness is unacceptable and is a result of poor sanding or sloppy stain install.

Redo the floors, unless you are will to live with a darker color.

Thanks Halley and G&S Floor. They didn’t sand the sample area by hand. It was all done the same way by machine. Still a mystery why the sample was so different than the final. But, we added another stain on top (finish coat wasn’t on) and it came out great. Had to redo a few rooms entirely bc stained wasn’t applied correctly. But it’s done and happy w the color.

Be on the look out for adhesion failure since, a second coat of stain was applied. Signs are blistering, flaking and chipping.

I was concerned about adding stain to stain so I spoke to several in industry prior to doing it, and they said as long as a finishing coat had not been applied to the wood, it was fine. Hopefully we won’t have any issues.
