Question 40

I removed the carpeting and drywall from one bedroom due to mold from a slow pipe burst. Now the mold is gone, the wall is repaired. I have a clean concrete slab floor. I have slightly painted the floor with a very watered down latex wall paint, just to see if it would adhere. I am looking at both your floor paint and the penetrating sealer. Is it too late to put the sealer on? Because I put the washed down paint on? I laid a towel down on one corner of the floor and it got musty. I think this is because moisture is slowly coming in the slab from outdoors. Would the penetrating sealer rectify this? Thank you for your help. View answer

Question 50

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.
