Question 6

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.

Question 14

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 29

I am interested in sealing my mudroom floor which is made of unfinished bricks. I was wondering if your penetrating sealer would be an appropriate product: http://www.greenbuildingsupply.com/All-Products/Paints-Coatings-Concrete-Masonry-Sealers/Green-Building-Supply-Penetrating-Concrete-Sealer The description mentions mostly exterior applications, so I wanted to double check regarding interior floor use. Also, would it be appropriate to use on a stoop directly outside of the mudroom door? View answer

Question 50

Hi - I created a new birdbath out of concrete that has imprints of leaves on the inside. I want to seal the birdbath including the inside that will hold the water. Is there a sealer that I can use that will be non-toxic to birds? I understand that the PH will be high on fresh concrete and that there are products that can reduce the PH of the concrete before sealing it. Will that be necessary before using the sealer? Although the birdbath is large (~ 2 x 2.5 ft.) I believe that I don't need a full gallon of the product. Can I get it in smaller sizes? Thanks, Steve View answer
