Welcome back gentlemen, Hydro ban literature says fabric is required only "at all joint, coves and corners" I'm reading that from the literature I have in front of me.So, I'm not suggesting anyone should use a product for something it was not intended for.A mini unit has about 50 sq.ft coverage. Enough to do a standard (48x34) pan with multiple coats. The pros like yourselves buy in quantity. The $200 number I've used would be an average cost if you purchase only enough for one pan.The costs go down per pan since your buying in a larger quantity you will have enough material to do multiple pans after the initial investment. A commercial unit ( 5 gal.- 250 sq.ft. is not 5 times the price) I have talked with LATICRETE about the possibility of including fabric with the mini units and rightfully so, they will wait to see the response and acceptance of my technique first.
The quote "and it's acceptable by the TCNA" comes from Mike's question. I didn't say it was endorsed yet at this point. I said early in the thread that I have been contacted by the TCNA as to the process to have it considered for the handbook. That takes at least 2 years. They are accepting requests now for the 2011 book.
Let me ask a question first. Is it true that the traditional method of mortar base pre-slope EXPECTS that the water WILL penetrate the tile and grout AND the mortar.So, water transferring and being trapped into the mortar
is just part of what is to be expected. Weep holes are designed to allow the water an escape but I'm sure you know that they can't be 100% effective in doing so. I'm trying to waterproof the pan above the substrate ( mortar in the traditional case) My liquid waterproofing is in theory doing the same thing as the liner except that the water isn't trapped below.Any water that penetrates the tile and grout(this will be a very, very small amount) will evaporate up and out. Not down and out only.
Am I thinking so wrong here? EVERY mortar base I have taken out had standing water trapped in the liner.No one has been able to actually prove to me that weep hole/pre-slope combination will work all the time. You will say that the pan was improperly built. Then EVERY pan I have seen HAS been improperly built and I go back to my statement that some of the problem is that we are not training the younger guys the proper technique. So, this technique I have come up with replaces mud set pans,does it well,and does it for less that the higher priced alternatives on the market. I wait for comments and again welcome critique.
