One finish you can use on cement boards is stucco. Extensive preparation is necessary, but once completed, you’ll have a beautiful surface, suitable for further finishing by painting or left as-is for a raw plaster look. Apply stucco to cement boards with the help of a fiberglass mesh for adherence.
Re: Plaster Over Cement Board You can use plaster weld to prime the surface. It’s a pinkish primer that gives you a base to Spackle to. Then use brown bag durabond with a handful of plaster of Paris and skim the area. You want it to dry fast so the next coat adheres.
Furthermore, can you plaster over durock? Note that only two-coat veneer plaster may be used over DUROCK cement board. Leave the surface rough and open for the proper bond of finish coat. Allow the basecoat to set to provide proper suction for the finish coat. IMPERIAL veneer finish is applied as indicated above for a one-coat system.

How do you transition from cement board to drywall?
The joint between cement board and greenboard is similar to the joint between two pieces of cement board or two pieces of drywall. Plan the installation so the last column of tiles overlaps the joint between the cement board and the greenboard if possible. Mix the thin-set mortar according the instructions on the bag.
Can I use joint compound on cement board?
When you buy cement board it requires the same installation materials as drywall but with a twist. Instead of using drywall joint compound to embed the tape in the cement board you should use thin-set mortar. We utilized the same thin-set that will be used to attach the tiles.
Do you have to tape cement board seams?
2 Answers. The thinset and mesh tape are to strengthen the seams. If you are going to tile over the cement board, you should tape the seams. If you just want to leave the corners untreated that will probably be fine, because that seam won’t split the center of a tile.
How do you finish cement board for painting?

What do you use cement board for?
Cement backer board is mainly used as a sub-surface for tiling. Cement backer board is often used as a tile base on plywood or OSB subfloor. Cement backer board on concrete as a subfloor or underlayment is usually not recommended or needed. In most cases, you can apply tile directly to the concrete.
Can Hardibacker get wet?
If the Hardibacker became brittle when wet, then that would be a disadvantage, but, as you might have noticed, it does not, which is another one of its assets. The backerboard is there to support the tile so that individual tiles set together as one unit once the thinset cures.
