Why aren't these 1/2" How are you supposed to match the Dry Wall around the Shower? This is crazy. The durock is listed as 1/2" too but it looked even thinner that these. Best way to cut? Saws or score and snap? Which is best? Thanks
Asked by: jdesan
I happened to notice that some plywoods are 0.205" thick. Hardie 0.42" + plywood 0.205" = 0.625", exactly 5/8". The sheetrock in my bathroom is 5/8" thick. Coincidence? There is then no allowance for a plastic sheet water barrier, but that is only a few mills. Maybe skip the plastic sheet and Redguard over the top out to where the edge (bullnose) tile covers.

I need to cut out for a niche in the shower...

I am not aware of any way to score and break. Is there a way to hand-cut or an approved power tool?
Asked by: Baltimore1000
Score and break works just fine. Score your opening and then an then an X from corner to corner. Be sure to support the backside of the board with some scrap 2x material along the anticipated opening. Use a framing hammer or similar to punch out the hole. I start near a corner and hold the hammer with a twist so the the edge of the face strikes near the score line and just work around the score lines until you have an opening. Using this method, you will have a rough edge to clean up. Generally I just use an old carbide blade in the skil saw and plunge into the cut. WEAR YOUR PPE - EYES, EARS, AND RESPIRATORY and work outside.

Three questions. I am making four 18" x 18" table tops for outdoor use in NY, covered with 3/4" glass mosaic tiles. The tables were custom-made by an ironworker with an open top frame with a 1" lip into which the Hardie board will be inserted (and removed for storage during the winter). 1. Will Home Depot cut the 3 x 5' sheet for me? We need four pieces 17 7/8" square. 2. In that 18" span, will the Hardieboard hold up without a plywood or other backing? The heaviest thing on the table might be a flowerpot or a tray with coffee cups. 3. The tile company (Modwalls) recommended using modified latex thinset, then outdoor sanded grout. Do you agree? I've done this before with the wrong materials and the tops eventually deconstructed.
Asked by: NuJulia
My HD will not cut, also HD will do rough cut of lumber so you can get into a car/van. No HD is going to cut 17 7/8. You need to do that at home.

I was hoping to use this for my shower, but after 6 attempts to score and snap 3 pieces for my curb, I'm still striking out. I've scored both sides 3 times each and it just randomly breaks somewhere else. I used the carbide scoring tool from qep, it scores pretty well. If it's going to be this hard to just snap pieces for a curb I don't see this stuff going into the rest of my shower. I'm probably going to go with kerdi, lots more $ but otherwise I'm going to have to buy the 150d cutting tool.

I used this Hardie Backer .42" today and cut it with a cement board circular blade, CMT 7-1/4" Fiber Cement Blade, Model Number: 236-004-07, $44.99 using a dust mask outdoors and it cut like a dream. I have tried cutting other brands with scoring with a knife and had the same results as most people. This product did not crack and chip like Durrock. I found the exact Hardie recommended screws at HD with the self counter-sinking heads and I hope and suspect they will do better then the generic screws I have used in the past. Do not like the idea of roofing nails since they have no holding power whats so ever. I suggest using a impact driver and hardbacker screws.

I have never built a shower before so time will tell if this was the right choice. However I have used Hardie Backer Board on two tiled floor projects and My husband has used Hardie cement sideing on two of our houses so that is way I picked Hardie once more for this project.

Embedded polymer fiber makes it strong and resilient; it doesn’t crumble like other cement board brands. Small cutouts can be made with a jigsaw. Long straight cuts you score and snap. you will burn thru jigsaw blades pretty fast!

Rated 5 out of 5 by from Best Board in the Market I have been in the industry for 35 years and I find this board to be the easiest to work with, strongest and best for mold and moisture. I tried all the other cement boards like Durock and Wonderboard, yet, those are messy, less than 50 % cement, hard to cut, and get mold through time. For all those out there, HB can be cut with a utility knife indoor - snap and score ( popping the board up instead of down like dry wall), you can hammer the board and it won't deteriorate, make sure to wet the board to get the best adhesion to tile, and put an additional layer of versabond to match the drywall. Holes are easy to perform as well. I GET 0 CALL BACKS WITH THIS BOARD and NO MOLD OVER THE LIFETIME OF MY INSTALLATION. BEST RETURN ON INVESTMENT FOR SECTION 8 BUILDERS CONCERN ABOUT MOLD.
