install it and specifies the training required for persons installing it. If you do not own a copy of this stan- dard, it is available for purchase from the NTCA’s bookstore at: https://www.tile-assn.com/store/ ListProducts.aspx?catid=398904 or https://bit.ly/2oLCCsL. You are correct that any instal- lation on a post-tensioned above ground slab will require special considerations. TCNA Handbook method EJ-171 addresses some of these concerns. It is the respon- sibility of the project’s specifier (i.e. architect, structural engineer, etc.) to develop the jobsite-specific drawings, material and installation specifications that will guide your installation. This includes details for movement joint placement. If these documents and clear instruc- tions are not included as part of the statement of work or drawings, you need to request them. ANSI A137.3 / A108.09 defines the “Gauged” (thickness) compo- nent of Gauged Porcelain Tile / Panels (GPTP) in two categories: 3.5mm - 4.9mm thick and 5.0mm - 6.5mm thick.The standard allows for installation of the thicker 5.0- 6.5mm material on floors and walls. The 3.5-4.9mm thick mate- rial is for use on walls only (not floors). Some manufacturers will allow for the use of their thinner GPTP material on floors. I strongly recommend you make absolutely certain that you receive a jobsite- specific warranty from the GPTP LATICRETE recently launched HYDRO BANⓇ Quick Cure, a liquid-applied, ready-to-use waterproof- ing mem- brane, and Quick Cure Mortar Bed, a pre-mixed, polymer-for- tified, thick- bed mortar, to provide the indus- try’s fastest mortar bed shower system installation. While other systems on the market may require up to four days to install a shower system, using HYDRO BAN Quick Cure and Quick Cure Mortar Bed in conjunction allows for following trades to begin tiling within hours. HYDRO BAN Quick Cure is available in a 1 gallon (3.8 liter) pail and Quick Cure Mortar Bed is available in a 60 pound (27.3 kilogram) bag. Both HYDRO BAN Quick Cure and Quick Cure Mortar Bed are eco-friendly, emitting low VOC, and compo- nents of the LATICRETEⓇ Lifetime System Warranty provide peace of mind for trouble-free installa- tions. www.laticrete.com.
