Concrete sealing

12 years ago

So here is the situation:

We are remodeling the basement We had a modern vinyl peel and stick tile over a previous cutback adhesive. We got an adhesive remover and started pulling up the adhesives. It was going great until my wife announced that she like the floor soo much she wants us to just seal the floor as it is now.

It has a little bit of cutback residue in those stubborn spots mostly along the edges. She doesn't want to do anything else to it. Just seal it like it is right now. I think she is crazy but then again she bought me a 120" 4k resolution projector setup and frankly I don't care if we plant grass down there.

The question: Would a solvent based poly, work over the slight bit of cutback residue? Or should I just tell her hell no?

Bare, cleaned and sealed concrete can be one of the most permanent and maintenance-free flooring options available. Discuss what your wife wants to do with a concrete restoration specialist...not a typical DIY project IMO.

You just can't throw a floor polyurethane down and hope for the best; the product must be one designed for the application.

Let me clarify.

In general I think stained concrete is a poor flooring choice for a residential structure. It can be striking and impressive at first blush but it is completely impractical and in a basement without radiant heat cold and generally uncomfortable. I am consoled by the fact that the lion's share of the floor will be covered by a rug.

The concrete restoration specialist will present me with three options 1) grind the floor to a smooth surface, (this is obviously a popular option as you can find many youtube videos of professionals with grinders going over floors with the tell-tale dark stains of cutback residue aka asbestos ridden tar that is very safe until some idiot takes a floor grinder to it) or 2) Lets throw some top coat or skim coat on it to completely cover up the effect you are trying to protect or 3) Throw a floor polyurethane on it and hope for the best.

Which brings me to the fact that I could just throw a floor polyurethane on it and hope for the best. But instead I wanted to check and see if anyone had any knowledge or experience with an oil based poly adhering to a floor which has absorbed the petroleum based cutback.

Or put another way I can think of no reason why a petroleum based adhesion product will not adhere to another petroleum based adhesion product, but I would like other confirmatory or dissenting opinions.

Nothing is going to stick to the old cutback-type adhesive.

Talk to someone who works with concrete coating products...there may be a coating out there that will marry over adhesive residue.

Rustoleum has an epoxy-type concrete sealer that may be of interest to you and is available at Lowes and probably Home Depot. Also, Abatron from Wisconsin sells concrete restoration products.
