Do you tape durock seams?
For tile backer boards such as Durock, Wonderboard, Hardiebacker, Permabase, and others the seams between the board need to be treated with 2-inch alkali-resistant mesh tape.
Can you use joint compound on durock?
Joint compound is used to help provide a seal between the Durock panels and to fill the depressions left by either nails or screws during installation. With proper finishing, Durock can be painted smooth and the seams will be completely hidden.
How do you finish the seams in durock?
Cut fiberglass mesh tape to fit in a single layer over every joint where the panels meet, but do not overlap the tape. It’s OK if it’s an inch or two short in spots. The tape is self-adhesive and will stick to the Durock panels. Press and smooth the tape firmly in place.
What do I use for durock seams?
Fill joints with latex-fortified mortar or Type 1 organic adhesive and immediately embed alkali-resistant, fiberglass mesh joint tape. Install tile.

What thinset should be used with Durock?
To install the Durock down to the floor, use an unmodified thinset (cheap) under it and you’ll be perfectly fine. The difference is this: Unmodified mortars don’t have latex added to them and have little “grab” to the materials they are sticking to. Modified mortars have latax in them and have a stronger “grab” to them.
Do I need to seal Durock?
Durock is indeed waterproof, meaning it is not harmed by water. But it is by no means a barrier to water. Do I need to seal cement board before tiling? Although most backerboards currently available won’t fall apart when exposed to moisture and are somewhat water-resistant, they aren’t waterproof.
What is cement board?
Cement board may be used as a backing for tile. Cement board is a building material made of a mixture of glass fibers and cement, usually formed into 4 by 8 foot sheets, 1/4 or 1/2 inch thick. It is typically used as a backing for tiled walls and floors, or on the exterior of buildings.
