Floor Renovation Question:
I have a very troubled concrete floor. When I removed the carpet from my living room, I found all the baseboards had been stained in the middle of the floor leaving brown wood stain everywhere. I’ve cleaned and cleaned but the staining will not come up. I’d prefer to avoid sanding the concrete because of the mess. Are there any other options to finish this floor?
Unfortunately, finding a messy concrete floor under your carpet is fairly common but it’s not the end of the world! It’s true that we would typically recommend sanding the surface to remove any topical debris. In your case, the stain is soaked into the concrete and there’s nothing on top of the concrete so it is possible to finish the floor without sanding.
The floor does need to be completely clean and dry. Quality surface prep is key but it isn’t necessary to remove the wood stain entirely to proceed. We recommend using the DCI Tinted Water Based Sealer and DCI Concrete Dye for this project. You’ll begin with two coats of tinted sealer to cover the stained areas and create a rich base coat color. I would suggest selecting a color as dark or darker than the wood stain on the floor to ensure good coverage. DCI Concrete Dye can be used to accent the floor with additional color to potentially cover any areas that need touching up and to bring a little movement to the floor. It’s an optional step but really does add something to the final finish. If you do elect to use the concrete dye, you’ll need to seal the floor again using a clear coat of Krystal Kote High Gloss or DCI Water Based Sealer. I’ve selected the water based products for your project because it is indoors and low odor sealers are easier to work with indoors.
This is a popular option for commercial floors, basements and a project like yours! One of our contractors, TCB Construction in McLoud, OK, specializes in projects like this one and has a few pictures that would definitely be helpful to demonstrate the step by step process.
