Blanke Permat Tile Underlayment 6.5 sq ft Single Sheets

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. Blanke PERMAT also supports wood substrates, reducing deflection and providing greater compression and tensile strength than plastic roll products. The Blanke PERMAT is stable, can walk on during installation, and does not require additional curing time when installing porcelain with a latex-modified thin-set.

Features

• 1/8" thick
• Dimension 6.5 sq ft and measures 2 ft x 3.2 ft.
• No extended cure time for latex-modified thin-set 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 a layer of 3/4" plywood on 24" o. c. joist spacing
• 10 years replacement warranty against problems caused by excess deflection, the 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 thin-set mortars under porcelain tile
• Lightweight; easy to install
• Self-seaming panels prevent substrate movement stress from transmitting to the tiled surface

Instructions for Installing Permat

• The substrate must be clean, dry, flat, and load-bearing
• Trowel a more liquid than normal mix of thin-set mortar onto the substrate
• Lay the Blanke PERMAT panels in a row so that the mesh overhang on the two sides of a panel covers 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 thin set, ensuring that the fabric on the underside of the panel achieves complete contact with the thin set and that there are no air bubbles
• Use the flat side of the trowel to key inset into the voids on top of the Blanke PERMAT
• Set the tile using a notched trowel appropriate for the type of tile and traffic. (Read Blanke PERMAT Installation Instruction before 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
• Blanke PERMAT is ideally suited for new home construction where demanding installation schedules cause traffic to cross on the underlayment before 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 than16"x16") 24" o.c. joist spacing, minimum subfloor thickness: 3/4" (subject to maximum joist span restrictions)
• Concrete substrates Substrates covered with stone, tile, and vinyl (consult thin-set manufacturer instructions) Floor heating systems (consult Blanke installation instructions)
