paint over kerdi board
Yes you can paint over kerdi board but you will need to give it a light coat of joint compound and do a little sanding. share | improve this answer | follow | answered aug 5 '19 at 22:56. jack jack. 22.2k 2 2 gold badges 19 19 silver badges 54 54 bronze badges. 1.. Schluter kerdi is a waterproofing membrane.. it ensures water stays in and does not escape behind the cement board of a bathtub or shower enclosure into the framing. as we have established in a past post, grout is porous.if you end up with mold growth behind the wall, it’s going to be because of some other problem from the other side of the wall, not the shower side.. The kerdi-board sits nice and flush with the studs. only use schluter screws and washers to attach kerdi-board to the studs. furthermore, the maximum on-center spacing for the screws and washers is 12 inches. kerdi-board is one of my favorite waterproofing boards because it’s light, easy to cut and has lines on it for aligning the screws..
