You really want the reinforcement when and where the instructions call for it. Not saying it will fail, but it has a much higher probability, and if you do not follow the manufacturer's instructions, you'd also not have any warranty to fall back on. No idea where in Texas you are, but maybe a call to CustomBuildingProducts could locate someone nearby that carries it.

RedGard Liquid Waterproofing or RedGard Sheet Memberane Waterproofing

....Not saying it will fail, but it has a much higher probability, and if you do not follow the manufacturer's instructions, you'd also not have any warranty to fall back on.....

Much higher probability than what Jim? So are you saying that or not?

Is it better than Hydro Ban? Better than Kerdi?

What of the instructions say reinforcing is not required in the corners?

What if the poster was looking for the Red Sheet membrane similar to Kerdi and NobleSeal TS?

More BS from John, not helping, and diluting and polluting the forum. The OP question was on RedGard when used to waterproof a shower and the use of reinforcement fabric. They specify it in some circumstances, and wouldn't if it didn't help make a reliable install. If you do not use it, it probably will fail over time, but you might be lucky. Few things in life are cast in stone, except that sometime, you will die. Nobody is going to say it will absolutely fail, just like some people get away without using thinset underneath cbu on a floor, but eventually, it usually does fail.

Since the OP asked about Redgard, and actually spelled it correctly, my thought was that they had a clue about the actual product they were asking about...not whether I thought it was the best for their job. Redgard works if you apply it properly, it's just not my favorite product. The manufacturers have a vested interest in your project working, and to do that, you must follow their installation instructions.

Waterproofing Shower with RedGard

Jim RedGard has two membranes (did you see the pictures above?). On liquid and one like Kerdi.

You said something about it failing. They have not even started yet.

I wanted to make sure they did not use RedGard to install RedGard Sheet Membrane. I think you are missing something here.

Reinforcing Mesh for RedGard


Looks like Custom wants this style mesh to reinforce their RedGard product. The Instructions for RedGard call for this when cracks in the substrate are more than 1/8" and if you want more strength in the waterproofing. The instructions state the mesh is not needed to meet the base ANSI 118.10 requirement and that the product is light commercial rated. The complete details are here: http://www.custombuildingproducts.com/TDS/TDS-104.pdf

More Info on Custom's reinforcing mesh: http://www.custombuildingproducts.com/products/surface-preparation/membranes-underlayments/waterproofing-and-anti-fracture-membrane-mesh.aspx

I've read online that some installers have used Laticrete's mesh for this step. I have read online others have used more readily available roofing mesh for this step. Best call the Custom Building Products Tech Support Line @

Found this picture looking for the reinforcing fabric. Did not know Ditra was a breakfast item! LOL - love the propped shot.
