The problem can be a variety of causes.

Perhaps your basement floor is 'damp' and the moisture is 'pushing' its way up to the surface to evaporate. (Maybe that's why you thought sealing it was the answer to your problem?) Normally, the test is to lay down a 2' x 2' piece of plastic and duct-tape all 4 sides COMPLETELY down to the concrete. And in a couple of days, rip it up to see how much 'moisture' is under there. Depending, it may NOT be OK to seal it ...

The other problem may be in the material itself. Did you read the container??! There are different sealers for different applications. You probably wouldn't use a driveway sealer in the basement because, well, of water/condensation issues. Read the label again to be sure it 'fits' your application. The only other thing that comes to mind is - you get what you pay for. I, personally, don't even BLINK at Thompson's. Years ago, when they first came out, they had the market on 'affordable' stains & sealers. Today, there are a lot more companies making better products. What you should do is spend a few more $$$ on good material. And the only way to find out what's RIGHT to do and what's GOOD to use, you need to have your 'problem' professionally assesed by 2 or 3 contractors. Other than that, you need to find yourself a way to self-educate in this area. Your problem may not be as easily fixed by 'painting' on a sealer.

My best to ya and hope this helps.
