SPECIAL NOTE:
Mer-Krete Thin-Set 801 is a new hybrid formulation developed for
use in installations of non-porous tiles over sound mats, waterproof
and crack isolation membranes as well as any other non-absorptive
surfaces. Unlike regular thin-sets, all the water is hydrated within
the Thin-Set 801 system rather than requiring evaporation. Thin-Set
801 is warranted to adhere to all substrates designed for ceramic,
porcelain and stone tiles.
RECOMMENDATIONS:
No sealers, curing compounds or coatings shall be used on the substrate.
Surfaces shall be left clean. Any contaminants shall be removed
prior to application. Spread only as much mortar as can be covered
in 30 minutes. Dusty or dry concrete surfaces should be washed with
clean water just prior to commencing work and left uniformly damp
(no standing water). Pot life is 90 minutes with open time of 30
minutes @ 70°F and 50% R.H. Patching, leveling or areas requiring
a mortar bed should be prepared using Mer-Krete Underlayments.
I NSTALLATION:
Work should be performed only by a trained applicator and in strict
accordance with ANSI A-118.5 methods and manufacturer application
specifications, abbreviated below: The amount of water used will
depend on the temperature and humidity. Higher temperatures and
drier humidities will require slightly more water to reach optimum
spreading consistency. Approximately 1 3/4 gallons of water will
wet out one 50 lb. sack of Thin-Set 801. In high temperatures (over
90°F), the use of cool water will extend open time and pot life.
• Expansion joints shall be spaced per current TCA manual
and shall be installed
against all restraining surfaces. Consult current TCA manual for
expansion joint recommendations.
• Grout or point all joints using prepared grout with enough
150 Acrylic Latex to bring the
mix to a workable consistency. |
