LevelQuik

RS Rapid Setting Self-Leveling Underlayment has

been rated by the Tile Council of America (TCA) for use as part

of a ceramic tile installation system for plywood subﬂoors with

24" o.c. joists. With proper installation of the ﬂooring system,

the use of LevelQuik

RS can achieve an “Extra Heavy” rating

for extra heavy and high impact use in food plants, dairies,

breweries and kitchens.

CUSTOM

recommends LevelQuik

RS, as well as LevelQuik

ES Extended Setting, as an alternative to TCA installation

methods F149-02 EGP (double layer of plywood) and

F147-02 (uncoupling system) cited in their 2002 handbook.

The double layer of plywood method requires two layers of

23/32" (18.2 mm) exterior grade plywood. The uncoupling

system consists of installing a 3/8" (9.5 mm) minimum layer

of plywood over the 23/32" (18.2 mm) plywood subﬂoor and

installation of an uncoupling system such as Schluter

Systems' DITRA.

The installation system consists of a LevelQuik

Self-Leveling

Underlayment installed at 1/2" (13 mm) thick over the

23/32" (18.2 mm) plywood subﬂoor with metal lath installed.

The metal lath must be a minimum of 2.5 lbs./sq. yd.

(1.13 kg/.83 M

). This system provides a more stable

substrate on which to set tile than the double layer of plywood

method, and is less expensive and labor intensive than the

uncoupling system.

Any CUSTOM

polymer-modiﬁed ANSI A118.4 mortar, such as

VersaBond Flex

Fortiﬁed Thin-Set Mortar, is recommended as

the setting material for this system.

Please contact CUSTOM

Technical Services or an

architectural representative for speciﬁcs on achieving an

“extra heavy” rating and further information.

TB92 CONCRETE CURING COMPOUNDS: WHAT TO DO WHEN INSTALLING TILE OR A SELF-LEVELING UNDERLAYMENT When installing tile on a new concrete slab, the first thing you should do is make sure the texture of the surface is appropriate and ask if a curing compound was used on the concrete. If this critical step is not taken, residue can result in a poor bond of the tile to the concrete surface.

TB92 CONCRETE CURING COMPOUNDS: WHAT TO DO WHEN INSTALLING TILE OR A SELF-LEVELING UNDERLAYMENT install underlayment or ceramic tile over. Dissipating curing agents rely on UV and abrasion by traffic to be adequately removed. Many areas in a building will not receive a sufficient amount of UV from sunlight to Break down the coating and traffic patterns may be insufficient to breakdown and remove the coating.
