Hydroban and grab bars

salbwilOctober 7, 2012


I am coating my cement board with Hydroban before tiling and want to install a grab bar on the wall above the tub after tiling. Iunderstand having to place a suitable backing board behind the cement board , but how do I ensure the screw holes for the bar don't allow water in behind the Hydroban ?

Thank you,

I'll drill pilot holes, fill them with squirts of silicon or sealant, then insert the screws. Clean up any squeeze out.
