Installing stone tile on subfloor

May 20, 2020
Minimum subfloor for marble

The Blanke•PERMAT is a forward thinking uncoupling underlayment which provides most of the labor saving great things about the old plastic roll methods. The Blanke•PERMAT additionally adds help to wood substrates thus lowering deflection and provides greater compression and tensile strength than synthetic roll items. The Blanke•PERMAT is stable to walk on during set up and does not require additional curing time whenever setting up porcelain with latex customized thinset.

For stone tile installations, Blanke•PERMAT offers amazing break isolation security, superior compression and tensile power. The Blanke•PERMAT reinforced mesh panel design adds significant support to lumber subfloors, significantly decreasing straight subfloor activity (deflection). And in many cases, using Blanke•PERMAT really replaces the necessity for an extra level of plywood to reinforce a floor to-be tiled with rock! That means there's no considerable boost in the level associated with rock set up if Blanke•PERMAT is used!

10 Year Guarantee
Significantly, Blanke•PERMAT has actually a 10-year warranty against damage due to exorbitant vertical subfloor motion (deflection), truly the only such warranty in the market. Whether installing stone on timber or concrete subfloors, property owners who feature Blanke•PERMAT in their stone tile installments can be confident their particular subfloors will indeed support the set up.


  • Reinforces timber substrates
  • Only one level of 3/4" plywood required under most basic stone installations
  • Provides uncoupling / break isolation defense on concrete substrates
  • Only 1/8" thick - lessen transition level specially to timber laminate flooring
  • 50 % higher compression strength and 7 x better tensile strength than rolled uncoupling items

Blanke•PERMAT set up without rise in level of stone installation!

With Blanke•PERMAT

Old-fashioned set up (rolled uncoupling pad / cement board) with a substantial escalation in height of the rock stile and the adjoining lumber floor.

Installation with rolled uncoupling pad
Installation with concrete board
  • Reduces deflection in wood substrates (for example. 24 o.c. joist spacing)
  • Rock installments – Increases substrate assistance
  • Big format tile – provides flatter airplane and stiffer substrates
  • Only 1/8” thick
  • Suitable for all dimensions tiles including mosaics
  • Weighs just 1.06 lbs. per panel (6.5 sq.ft)
  • Latex changed thinset recommended for porcelain tile set up
  • Break isolation/uncoupling defense
  • Exceptional point load help
  • Ideal for tiles under 2” x 2”
  • Higher compression energy
  • Greater shear energy
  • Simpler to put in
  • Perfect for flooring confronted with heavy traffic (auto showrooms, airports,
  • retail, nursing homes, hospitality)

Plywood or OSB Subfloors:
Joists spaced 16” o.c. and 19.2” o.c.: minimal one layer 3/4” thick subfloor.
Joists spread 24” o.c.: minimal 3/4” dense subfloor plus 2nd level of 3/8” thick plywood or OSB.

Cement Subfloors:
Blanke•PERMAT provides excellent security against damage caused by stress cracks and lateral action typically present in concrete substrates.
