Mer-Krete™
300
WATERPROOF MEMBRANE SYSTEM
DESCRIPTION:
300 Waterproof membrane is a latex modified, fabric reinforced
system formulated and prepackaged at the factory. Formulated with
special latex compounds.
USE:
This membrane provides positive waterproofing for above grade,
interior thin-set applications of ceramic, quarry, stone tile
and vinyl.* The membrane has an approximate thickness of 1/8",
and therefore does not interfere with existing elevations or doorways.
ADVANTAGES:
• Quickly installed. Cures in 24 hours allowing next day
overlay.
• Completely waterproof with zero porosity.
• Should be turned up for base flashing and applied to walls
for wainscot or shower wall application.
• Thin section – does not interfere with elevations.
• Will not burn – fire retardant
• May be installed over a slip sheet for heavier section
toppings (i.e. concrete, Portland Terrazzo, etc.).
LIMITATIONS:
• Will not bridge substrate expansion joints without developing
hairline checks. Consult a Mer-Krete technical representative
for required special treatment.
• Wood subsurfaces must be adequately blocked at joints.
Joints that are open more than 1/16" must be filled with
suitable underlayment prior to the application of the membrane.
