The Blanke•PERMAT is an innovative uncoupling underlayment that offers all the labor saving benefits of the old plastic roll systems. The 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.

For stone tile installations, Blanke•PERMAT offers amazing crack isolation protection, superior compression and tensile strength. The Blanke•PERMAT reinforced mesh panel design adds major support to wood subfloors, greatly reducing vertical subfloor movement (deflection). And in many cases, using Blanke•PERMAT actually replaces the need for a second layer of plywood to reinforce a floor to be tiled with stone! That means there is no significant increase in the height of the stone installation if Blanke•PERMAT is used!

10 Year Warranty
Importantly, Blanke•PERMAT has a 10-year warranty against damage caused by excessive vertical subfloor movement (deflection), the only such warranty in the industry. Whether installing stone on wood or cement subfloors, homeowners who include Blanke•PERMAT in their stone tile installations can rest assured their subfloors will indeed support  the installation.

Advantages
• Strengthens wood substrates
• Reduces vertical subfloor movement (deflection)
• Superior compressive strength
• Crack isolation properties (uncoupling)
• Superior resistance to delamination during installation
• Lightweight; easy to install
• Self-seaming panels prevent substrate movement stress
   from transmitting to tiled surface

• Reduces deflection in wood substrates (i.e. 24 o.c. joist spacing)
• Stone installations – Increases substrate support
• Large format tile – provides flatter plane and stiffer substrates
• Only 1/8” thick
• Suitable for all size tiles including mosaics
• Weighs only 1.06 lbs. per panel (6.5 sq.ft)
• Latex modified thinset recommended for porcelain tile installation

• Crack isolation/uncoupling protection
• Superior point load support
• Suitable for tiles under 2” x 2”
• Higher compression strength
• Higher shear strength
• Easier to install
• Ideal for floors exposed to heavy traffic (auto showrooms, airports,
• retail, nursing homes, hospitality)

Plywood or OSB Subfloors:
Joists spaced 16” o.c. and 19.2” o.c.: Minimum one layer 3/4” thick subfloor.
Joists spaced 24” o.c.: Minimum 3/4” thick subfloor plus second layer of 3/8” thick plywood or OSB.

Cement Subfloors:
Blanke•PERMAT provides excellent protection against damage caused by stress cracks and lateral movement typically found in cement substrates.
