5 Instructions
General Surface Prep
Surfaces must be structurally sound. Remove all grease, oil, dirt,
curing compounds, sealers, adhesives or any other contaminant that
would prevent a good bond. Glossy or painted surfaces must be
sanded, or abraded, and stripped of all contaminants. Concrete must
be cured 28 days and accept water penetration. Concrete must be free
of efflorescence and not subject to hydrostatic pressure. Concrete
slabs should have a coarse finish to enhance the bond. Plywood
flooring including those under resilient flooring must be structurally
soundand meet all ANSI and deflection requirements. For questions
about proper subfloor installation, call Technical Services. Smooth
concrete surfaces, existing glazed tile, terrazzo, or polished stone
should be scarified. Sheet vinyl must be well bonded and stripped of
old finish. Roughen the surface by sanding or abrading, then rinse and
allow to dry. Expansion joints should never be bridged with setting
material. Do not sand flooring materials containing asbestos. Ambient
temperatureshouldbemaintainedabove50°F(10°C)orbelow100°
F(38°C)for72hourstoachieveproperbond.
Bonding to Concrete Surfaces
Concrete or plaster must be fully cured and must accept water
penetration. Test by sprinkling water on various areas of the substrate.
If water penetrates, then a good bond can be achieved; if water
beads, surface contaminants are present, and loss of adhesion may
occur. Contaminants should be mechanically removed before
installation. Concrete must be free of efflorescence and not subject to
hydrostatic pressure. Concrete slabs should have a coarse finish to
enhance the bond. Smooth concrete slabs must be mechanically
abraded to achieve proper bond.
Bonding to Lightweight Cement and Gypsum Surfaces
Lightweight or gypsum based underlayments must obtain a minimum
2000 psi (13.8 MPa) compressive strength. The underlayment must be
sufficientlydryandproperlycuredtothemanufacturer’sspecifications
for permanent, non-moisture permeable coverings. Surfaces to be
tiled must be structurally sound and subject to deflection not to exceed
the current ANSI Standards. Surfaces shall be free of all grease, oil,
dirt, dust, curing compounds, waxes, sealers, efflorescence, or any
other foreign matter.
All Lightweight cement or Gypsum surfaces should be primed. with a
properly applied sealer or a primer coat of RedGard, consisting of 1
part RedGard diluted with 4 parts clean, cool water. Mix in a clean
bucket 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 ft2/gal (7.5 M2/L). Drying time
depends on site conditions, but is normally less than 1 hour. Extremely
porous surfaces may require 2 coats. At this point, RedGard can be
applied to the primed lightweight or gypsum based surface. Refer to
the individual product data sheet or packaging directions for application
instructions. Expansion joints must be installed in accordance with local
building codes and ANSI/TCNA guidelines. Refer to TCNA EJ171.
