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. ๐คฆโโ๏ธ 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!!!

Needs top coat if used in the sun
Works but needs a top coat if used outdoors in the sun. Didnt know that when i bought 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.

Used for a crack in my tub. Just ended up going over the whole thing and it works great.
