Permat: the deflection reducing Uncoupling Underlayment
Blanke PERMAT is an innovative uncoupling underlayment that offers all the labor saving benefits of the old plastic roll systems.
Blanke PERMAT also adds support to wood substrates thereby reducing deflection and provides greater compression and tensile strength than plastic roll products. The Blanke PERMAT is stable to walk on during installation and does not require additional curing time when installing porcelain with latex modified thinset.
- 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 year replacement warranty against problems caused by excess deflection -- only warranty of its kind in the industry (see permat warranty for details).
- Superior compressive 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 form transmitting to tiled surface.
Blanke PERMAT is an innovative uncoupling underlayment that adds support to wood substrates thereby reducing deflection and provides superior compression and tensile strength when compared to plastic roll and cement board products. Installed with thinset mortar, the Blanke PERMAT panels feature a mesh overhang to connect adjacent panels thereby eliminating seams that can transmit substrate movement stress to the tiled surface.
Tile can be applied immediately after installing the Blanke 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 Blanke PERMAT.
Set tile using a notch trowel appropriate for the type of tile and traffic. (Read Blanke PERMAT Installation Instruction prior to installing this product).
Movement joints are required in the tile surface per industry standards.
Blanke PERMAT is an 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 prior to tile installation
