Some Guys Need To Test Things Themselves
"Henry, 254 applied over HydroBan on a regular concrete block. Cure time 2 days for the HydroBan then 5 days for the 254 . First pic is the chisel in between the block and the Cultured stone product . This is after I have hit it with a hammer 2 times."
"This is after 5 blows with the hammer and chisel. I am shocked with the bond of the Hydroban! The surface of the concrete block failed .
The aggregate on the piece of Cultured stone is bonded to the HydroBan, Truly amazing."
