AMES BMX1WRG 1 Gallon Blue Max, White Liquid Rubber Waterproofer,Regular Grade 1 Gallon - for Use in Interior & Below-Grade Exterior - Concrete Sealer, House Paint and More.

It is slimy. I used it to waterproof a concrete bird bath. I used two coats. I recommend letting it cure at least a week in warm weather before filling it with water. If you wait longer than what you think it should take to cure, it works great! I have a birdbath heater/fountain and the birdbath is completely sealed and waterproof.

Great Item, definitely worth the money. I need to order more.

This stuff is amazing. Completely stopped the leaks.

You are not going to believe how I used this product. I build a whole water tank just with the product. No mortar used. Nice and thick but no pasty. Application easy I used ketchup bottles to spread. I used 2 of them on a cabin roof and painted over for water proofing. If you are DIY. You need this. This is my 8 bucket order.

I used the White version Ames block and wall in my basement four years ago it seems to be holding up pretty decent. This Blue version I used on some wood behind the gutter it did not hold up very well.

This is great stuff. I have repainted my stock tank pool with it works great. One thing to note is that this is not like regular paint more of a consistency of runny snott. But does a great job water proofing over a primer also the white takes usniversal pigment really well. I added blue to it so i would have a light blue inside to my stock take pool.

I did extensive research on the best product to water proof an interior block wall. Blue Max is amazing. Easy to apply with a small roller and the coverage is very good. I applied two good coats. I did have to open a window for a couple of days to hold the odor down. I painted over it with typical good wall paint and any lingering odor was completely gone. I purchased the Ames peel and stick tape for along the floor and I applied it to the first area...then used the Blue Max Liquid over it. On another side I did not apply the Tape and I have to say the seal was so good I did not need to use the Tape the first time. I finished my job without it...only using the Blue Max. I do not have running water through the wall, just lots of moisture. It is Springtime here in the Pacific NW and there are seeps and springs on the outside of this wall. So I did not finish off this wall for the last two months, in order to see if what I applied would actually work. It Has! The wall and floor are dry. There is no musty smell and the paint has not changed in any way. I am now ready to complete my project and turning this area into good livable dry space.

Great product! Worked perfect for what we needed.
