Blanke Permat Tile Underlayment 6.5 sq. ft. Single Sheet Innovative uncoupling underlayment that offers all the labor saving benefits of the old plastic roll systems. It also adds support to wood substrates thereby reducing deflection and provides greater compression and tensile strength than plastic roll products. This tile underlayment is stable to walk on during installation and does not require additional curing time when installing porcelain with latex modified thinset. Features 1/8" thick Dimension 6.5 sq ft and measures 2 ft x 3.2 ft. No extended cure time for latex modified thinset mortars under porcelain tile Crack isolation properties (uncoupling) Permanent Support of high quality flooring, stone, marble Reduces vertical sub-floor movement (deflection) Interior use only Adds the extra substrate support for stone floor installation (max L/720 for stone vs L/360 for tile) Approved for ceramic tile installation over layer of 3/4" plywood on 24" o. c. joist spacing 10 years replacement warranty against problems caused by excess deflection only warranty of its kind in the industry (see permat warranty for details) Superior compressible strength Strengthens wood substrates thereby reducing deflection Superior tensile strength Crack isolation properties (uncoupling) Superior resistance to delaminating during installation No extended cure time for latex modified thinset mortars under porcelain tile Lightweight; easy to install Self-seaming panels prevent substrate movement stress from transmitting to tiled surface Instructions for Installing Permat Substrate must be clean, dry, flat and load bearing Trowel a more liquid than normal mix of thinset mortar onto substrate Lay the Blanke PERMAT panels in a row so that the mesh overhang on the two sides of a panel cover the seams of the sides of adjacent panels without the overhang Subsequent rows of panels should be placed so that the seams running perpendicular to the previous row are offset a minimum of 3" from the seams running in the same direction in the previous row Use the flat side of a trowel or a vinyl roller to press the panel into the thinset ensuring that the fabric on the underside of the panel achieves full contact with the thinset and that there are no air bubbles Use the flat side of the trowel to key thinset into the voids on top of the underlayment Set tile using a notched trowel appropriate for the type of tile and traffic. (Read Installation Instructions prior to installing this product) Movement joints are required in the tile surface per industry standards Typical Applications Ideal alternative to backer board underlayment used in interior residential applications over wood substrates where excess deflection may be an issue and in commercial applications on concrete where stress cracks can be a problem Ideally suited for new home construction where demanding installation schedules cause traffic to cross on the underlayment prior to tile installation Suitable Substrates Wood substrates stone and tile (including large format) Plywood EGP and OSB 16" o.c. joist spacing, minimum subfloor thickness: 5/8" 19.2" o.c. joist spacing, minimum subfloor thickness: 3/4" Wood substrates tile only (no larger than 16"x16") 24" o.c. joist spacing, minimum subfloor thickness: 3/4" (subject to maximum joist span restrictions) Concrete substrates.
