Install Waterproof Backer Board

[Music] this is a fancy method this is a schluter system and it is a waterproofing membrane it is a cement board replacement it is an all-in-one process so what we are going to do is we are going to cut this up use the specific screws that are water tightening screws to secure it through the studs basically you would hang sheetrock and then after that we would use a thinset and the waterproofing membrane on the joints joints just to make sure it's all one it's a little bit on the pricier side it's a three foot by four foot 36 bucks a piece i needed four pieces cement board's gonna take forever i i'd rather just throw this up and then be ready to tell tomorrow so that's my little rant back to work
