I am having a plumber putting in a new Sterling Vikrell tub on top of a bed of motar. I will be doing the tiling myself. I have done research by googling and youtube so far. I do know how to do tile but never done it in the bathroom before. So far from research, I know that I have to put a vapor barrier and then cement boards before I can tile. The questions are around the vapor barrier. I know that I am suppose to start from bottom to top and overlap 3 inches. Where the tub's edge, do I overlap it and compound it with roofing material? Then when I screw the cement board on top of it, I would use joint tape and thinset. Please let me know if this sounds about right or you would like to share any other tips. Also, if I use this a waterproof membrane as the link that I provided, would I need to put in a vapor barrier like mentioned above? What is that paper call anyway - tar paper?

I have some sealer and want to apply it to the backsplash on my kitchen. The backsplash is Travertine with thin grout lines. My plan is to apply the sealer to both the face of the travertine tiles as well as the grout lines. The directions on the sealer packaging say to wipe of any sealer that has not penetrated after about 5 minutes. I am a bit confused by these directions. Do I really need to wipe up any sealer that has not penetrated after 5 minutes? As mentioned before, I want the sealer applied to entire surface (face of the tiles & grout lines). I am concerned that if I wipe up any sealer after 5 minutes, it may limit or inhibit the coat of sealer from its full effectivenes. In a nutshell, should I still wipe up any sealer that has not penetrated after 5 minutes - or just leave it be and allow it to penetrate and evaporate untouched?
