Hydro Barrier and Hydro Ban

[ande]

My husband and I are remodeling 2 bathrooms, and in preparation for doing the 2 tub surrounds I have spent a lot of time reading posts on this forum. After reading about the various liquid membrane options, I decided to go with Hydro Ban, and I ordered a couple gallons of online. The supplier sent HydroBarrier by mistake. I called them, and they apologized, and said that they would send out the Hydroban (to arrive next week), and to just keep the Hydrobarrier. I wanted to start waterproofing this weekend. One of the 2 tub surrounds we are installing is ready to waterproof. But I do not have any fabric, nor can I obtain any in the small KS town where I live. SO! My question is, can I put on Hydrobarrier first (since it is the only product that is actually here in my house right now), and then apply Hydroban to the corners and joints when it arrives next week? Or do I need to wait for the Hydro Ban and apply it first?

Good question Andre,

My first impression would say it doesn't matter as the one will easily bond to the other.

I'd still use the fabric in the corners.

Make sure you apply thinset into the transition of the tub and the cbu.After this dries,you should tape just 3/16'' from where the white of the tub and thinset end,this will enable the tile with to cover this.Then paint this area in multiple light coats.H ban would be better as it has higher "adhesion" qualities.

This transition is the most "at risk" as the water penetration is the greatest here.

Thanks for posting your on ?? the forum.If I wouldve responded directly to your email than no one else could benefit from our replies.

Does cbu mean cement board? (Sorry for my ignorance!) I want to make sure I understand correctly. You are talking about applying thinset between the tub tile flange and the tile backer board, right?

[Houston Remodeler]

CBU = ceement backer unit. which is a general catagory that includes fiber cement (hardie) old school ceement (backer board) and the new lighter stuff with foam pellets or pumice (durock)
