Clean Polyurethane Self-Leveling Sealant Off Concrete
I was doing well sealing the joints around my cellar door when the back of the sealant tube blew out and dumped sealant on the patio.
Using water to clean it up seemed to make it worse. I dabbed up as much liquid sealant as I could. I was wondering what is the best way to get the rest cleaned up. Is there a specific solvent which is better to use?
We use Glaze-n-Seal stripper,[black can]on all concrete to remove sealers.very powerful stuff.it will etch concrete serface as well.so be easy.use a chip brush 1.00 each HD has them.go to your concrete supply they will have 1/2 pint samples.READ ALL LABLE.glove up, it will burn.It might take 2 coats to remove polyurethane.leave stripper on 1 minute at a time or less it drys faster in sun.use water with stiff brush to remove all stripper,let dry completely befor 2nd coat if needednow you have a very clean small area of your concrete patio.you may have to put a sealer over the clean area now.if it is a texured concrete,stained patio it wont hurt the finish.just pressure wash all of patio,put a high end sealer over.good luck.ken
