Question 18

Do you sell this in a smaller size? I am looking at sealers for my concrete 14 square foot shower floor. Your product sounds perfect for me except the cost per ounce options. Either I but a gallon at $.45/oz or a few of your samples at $.9/oz which (obviously) is double the cost. If I go with the lower cost per ounce option, I will have 119 oz left over. It seems if your product is to be used as advertised on "All Rooms, Basements, Bathrooms"...etc. I can't be the only homeowner with a small project wanting a smaller size than a gallon while also wanting the lesser $/oz cost.

I have a some questions concerning your GBS Penetrating concrete sealer. I want to use it on a basement floor that has some areas that were ground down to make it level.

I want to order it now when it will not get cold during shipping, but I plan to apply it on my basement floor later this winter. I can store it so it will not get cold and the basement room will be heated as well. Thanks , Julie View answer
