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

3. Compare to restrictions on other crack isolation products

Detail

Increases substrate support/reduces deflection

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

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 warranty

Applications – Residential

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

* Audi showroom, Piepenstock Germany

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

Upscale benefits of heavy-duty/premium uncoupling system

Installation

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

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 FlooringSupplyshop.com

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 vertical surfaces

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