How is PERMAT similar to rolled uncoupling products?

Blanke Permat  the ultimate uncoupling underlayment for residential and commercial Projects. by tiledepot.us

Light weight, labor savings, easy to install compared to backerboard/cement board

1. Easy to carry – 30 lbs vs. 362 lbs
2. Cut with utility knife - no dust
3. No screws or nails - installs with thinset
4. No taping of seams

Blanke Permat  the ultimate uncoupling underlayment for residential and commercial Projects. by tiledepot.us

Provides crack isolation (uncoupling) protection unlike backerboard type products

1. Fabric on underside releases with lateral substrate movement

2. Span controls joints in cement substrates (but not expansion joints)

3. Compare to restrictions on other crack isolation products

How is PERMAT superior to rolled uncoupling products?

Blanke Permat  the ultimate uncoupling underlayment for residential and commercial Projects. by tiledepot.us

Increases substrate support and reduces deflection

Superior point load support

Higher compressive strength

Higher shear strength

Easier to install

 

Detail

Increases substrate support/reduces deflection

Blanke Permat  the ultimate uncoupling underlayment for residential and commercial Projects. by tiledepot.us

1. Tile — approved over 1 layer of 3/4" EGP on 24" o.c. joist spacing

TCA recommends two layers of plywood over 24" o.c. joists

PERMAT replaces second layer of plywood

Robinson Floor Test rated -Heavy Industrial

2 Stone

Approved over 1 layer 3/4" EGP on 19.2" o.c. joist spacing

Stiffens substrate to meet more rigid L/720 deflection (vs L/360 for standard tile)

Schluter Ditra requires 2 layers of plywood under stone

3. Large format tile

Provides flatter plane for setting tile

Stiffens substrate

Fewer grout joints in the tiled surface allow for less movement/deflection

Blanke Permat  the ultimate uncoupling underlayment for residential and commercial Projects. by tiledepot.us

Superior point load support

95% higher than standard roll uncoupling products

No voids - no hollow spots to collapse under point loads

Ideal for commercial applications

Suitable for tiles smaller than 2" x 2"

Stone installations - supports 100% of tile

Higher compressive strength

50% higher than standard roll uncoupling products

Ideal for commercial applications (auto showrooms, retail, hospitality, grocery stores)

Blanke Permat  the ultimate uncoupling underlayment for residential and commercial Projects. by tiledepot.us

Higher shear strength

Blanke Permat  the ultimate uncoupling underlayment for residential and commercial Projects. by tiledepot.us

7X higher than standard roll uncoupling products

Blanke Permat  the ultimate uncoupling underlayment for residential and commercial Projects. by tiledepot.us

Easier to install

More tolerant of unwelcome traffic prior to tile installation

More flexibility in timing mat and tile installation

Less sensitive to thinset cure times when working on mat

Blanke Permat  the ultimate uncoupling underlayment for residential and commercial Projects. by tiledepot.us

Modified thinset (A118.4) recommended with porcelain tile

Complies with industry standards

Schluter requires non-modified thinset when installing porcelain on DITRA

Eliminates conflicts between thinset and underlayment warrantie

 

 

Applications - Residential

Blanke Permat  the ultimate uncoupling underlayment for residential and commercial Projects. by tiledepot.us

New home construction

24" o.c. joist spacing with 1 layer 3/4" plywood/OSB

Eliminates second layer of plywood

Stone installations

Stiffens floor to meet more rigid L/720 requirement

Provides higher point load and support under 100% of installation

Tiles smaller than 2" x 2"

Anywhere where substrate support is questionable

Blanke Permat  the ultimate uncoupling underlayment for residential and commercial Projects. by tiledepot.us

Anywhere crack isolation is required on cement substrates

Can alternative crack isolation products span control joints?

Anywhere exposed to high point loads and heavy traffic

Anywhere DITRA is specified

Upsale benefits of heavy-duty/premium uncoupling system

Installation

Please see PERMAT installation video and PERMAT printed installation instructions for detailed instruction

Blanke Permat  the ultimate uncoupling underlayment for residential and commercial Projects. by tiledepot.us

Normal floor prep

Align panels so top mesh overhang covers edge of adjacent panel side without overhang. Seams in adjoining rows must be offset a minimum of 3" from seam in prior row

As with the tile covering, a 1/4" gap must be maintained where PERMAT abuts vertical surfaces, thresholds and other flooring surfaces( i.e., wood)

Apply more a liquid than normal mix to substrate w/ 1/4" x 1/4" U-notched trowel

Blanke Permat  the ultimate uncoupling underlayment for residential and commercial Projects. by tiledepot.us

Press PERMAT in to thinset with flat side of trowel (fabric on underside of PERMAT needs to be saturated with thinset)

Key normal mix of thinset into cavities on top of PERMAT

Trowel thinset and set tile as normal to top surface of PERMAT

Allow normal cure time as recommended by grout manufacturer before grouting

A Word about Movement Joints

Movement joints are required in tile and stone surfaces

Importance of movement joints: Per the NTCA and TCA, most claims for failures are for installations with insufficient or no movement joints. Here are the minimum guidelines per 2007 TCA Handbook for installation of ceramic tile:

Interior: 20-25' both directions

Interior exposed to sunlight: 8-12’ both directions

Exterior: 8'-12' both directions

Perimeter and where tile abuts verical surfaces

These requirements apply regardless of type of underlayment used in the installation
