Hardie board 500 installation

My shower will be Neo Angle so there will be just two panels and one corner seam. The edge of the second panel butts up to the surface of the first panel in the corner. An adhesive bead is used to seal this joint and a piece of decorative corner molding is pressed into the corner and caulked.

Therefore the panels are not overlapping each other. Even if it takes more work or costs a little more money, I do want to be as conservative as possible in constructing the infrastructure for the shower wall panels. Originally I was thinking CBU was the best way to go and I want as much defense against leaks as possible with respect to waterproofing. I guess the same conservative philosophy applied to using CBU in the non-wet areas of the bathroom where I am going to tile the walls up to 48".

Since I have all of the Hardibacker in by basement already let me know whether you think I should stay with my original plan or whether I should return the Hardibacker in exchange for greenboard. If I were to use RedGard in the corner of the shower does anyone know if the wall panel adhesive will bond well to it? Is there another waterproofing alternative?! Thanks, Lew :crazy:. If you are using cementitious board such as Hardibacker, I think you are saying you anticipate moisture.

If that's the case, then you better look down and worry about a vapor barrier and waterproofing at the floor level. I believe all of this Hoo Haa is superfluous. I would just place my new sheetrock or clean the old and prime it, then install the panels as instructed. The waterproofing is not necessary. That fact and ease of installation should be the reason you chose this product line - assuming you like the look already. Slap it up!! Thanks Barrett, Actually I do have follow up questions relating to the floor but I was planning on opening up those issues in a new thread!

I'll ask a few now. I have already replaced my subfloor and underlayment following procedures that I researched within this forum and those outlined by the Engineered Wood Association I think it was Form My previous subfloor had disintegrated due to water damage.

I was able to remove it ply by ply although the joists were in good shape. The question is what type of waterproofing should be used to protect the floor in case of toilet overflow, etc. HardieBacker is an ideal choice for wet area walls; its smooth surface may be painted, textured, wallpapered, or tiled.

Brand: James Hardie. Update it in the field below. A carbide-tipped scoring knife is recommended, but you can also use a utility knife or shears. Never use a high-speed grinder to cut cement board indoors, since this can create a dust hazard.

Place your HardieBacker Cement Board on a flat surface and mark your cuts with a straight edge. Score along your straight edge, applying firm pressure as you go. Place your HardieBacker Cement Board on the floor and kneel on it for leverage. Applying pressure on two locations, snap the board upward along the score line.
