Durable strength & Waterproof Coating
Wow, what a great coating to support my underlayment cement board. The elasticity and water proof quality provides extra added durability to the cement board. One coating is great -2 would even be better.

BLUE MAX
Used this to waterproof a window sill in my shower, the previous owners painted it with regular water based paint. 🤦♀️ Needless to say, the paint eventually cracked and peeled, so the sill was in desperate need of the proper type of paint for this situation, Blue Max was perfect, I prepared the surface, and applied a few coats, it works great, and no odor, love it!!!

Give it a lot of time to cure.
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.

I've used Ames block and wall in my basement 4 years ago seems to work good with 4coats.
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.

Pet stained subfloor
I actually used this to seal my subfloors after attempting to neutralize pet stains. The stains were the worst! This product is amazing, easy to use, very easy to clean up. Would use 10 out of 10 for any waterproofing need.

NO information on the product
Got another galon to experiment with brush. Stunning luck of i formation. No word states on; Is any solvent available / what kind of if any ( it's possible to thin it with water or anything else? ) I would like to use this paint with an air spray gun- does it need a special equipment / hardware to do so?) Where is MSDS information about this chemical? I was hoping to get all of it along with the product, but NOTHING was attached to it! Taking two stars because of that.
