ANSWER. ANSWER – No there should not be a gap between the top of the bathtub flange and the backer board on the wall. The asphalt paper or polyethylene should overlap the tub flange so moisture that collects on the moisture barrier can evacuate into the tub; or more important so it can’t get into the wall cavity.Click to see full answer. Likewise, does cement board go over lip tub?The best approach when installing cement board or other tile backer around a tub is to keep the cement board out of the lip area. Apply it to the wall with the bottom edge about 1/4 in. above the lip of the tub.Subsequently, question is, can you tile directly on cement board? Cement board is used for most floor tile and has all but replaced plywood and drywall backer materials for wall-tile applications in wet areas, like showers and tub surrounds. Ceramic tile laid over cement board is one of the most durable floor or wall surfaces you can install. People also ask, do you put cement board under a shower pan? Should the shower pan be set in mortar anyway (even if I level the cement board subfloor)? You don’t really need cement board under the pan, but you do need a level solid surface. Leveling cement would be all that is needed, but should be thicker than 1/2″.Does it matter which side of cement board faces out?Cement board has a smooth side and a rough side. Face the rough side out if you will be using thin-set mortar adhesive to install the tile but the smooth side out if you will be using latex mastic.
