5 Instructions
General Surface Prep
USE CHEMICAL-RESISTANT GLOVES, such as nitrile, when
handling product.
Exterior and wet areas must have proper sloping to drains. All surfaces
must be structurally sound, clean, dry and free from contaminants that
would prevent a good bond. Newly prepared concrete must be
troweled smooth and textured to a fine broom finish and cured for 28
days. Existing surfaces must be scarified and leveled, and all defects
must be repaired. Cracks exceeding 1/8" (3 mm) should be treated in
accordance with TCNA F125 or TCNA F125A.
Bonding to Lightweight Cement and Gypsum Surfaces
Lightweight or gypsum-based materials must obtain a minimum of
2000 psi (13.8 MPa) compressive strength at the recommended cure
time. The underlayment must be sufficiently dry and properly cured to
the manufacturer's specifications for permanent, non-moisture
permeable coverings. Surfaces to be covered must be clean,
structurally sound and subject to deflection not to exceed the current
ANSI standards. Expansion joints must be installed in accordance with
local building codes and ANSI/TCNA guidelines. Prime all surfaces to
receive RedGard® with properly applied manufacturer's sealer or with
a primer coat of RedGard®, consisting of 1 part RedGard®, diluted
with 4 parts clean, cool water. In a clean pail, mix at low speed to
obtain a lump-free solution. The primer can be brushed, rolled or
sprayed to achieve an even coat. Apply the primer coat to the floor at
a rate of 300 ft/gallon (7.5 M/L) of reduced material. When dry, apply
at least one full coat of RedGard® to the primed area.
Vapor Barrier
When used as a vapor barrier, apply one full coat (70 sq. ft. per
gallon) where vapor transmission is up to 8 lbs. per 1000 sq. ft. per
day and two full coats (70 sq. ft. per gallon each coat) where
vapor transmission is up to 12 lbs. per 1000 sq. ft. per day. Refer to
ASTM F1869 for more information on Vapor Transmission Testing.
Movement Joint Placement
Do not bridge joints designed to experience movement. Carry these
types of joints through the tile work. Clean the joint and install an open
or closed cell-backer rod to the proper depth, as outlined in the Tile
Council Handbook, EJ171. Next compress sealant into the joint, coating
the sides and leaving the sealant flush with the surface. When the
sealant is dry, place bond-breaker tape over the joint. Apply a
minimum3/64"(1.2mm)ofRedGard®overthejointandthe
substrate, following the instructions provided previously. Install the tile
work onto the membrane, but do not bridge the joint. After the tile
work is properly set, follow the architect's and manufacturer's
instructions to fill the joint with a specified color sealant.
