TILING 09 30 00 Surface Prep / TDS-104
RedGard at Drains
Drains should have a clamping ring with open weep holes for thin-set
application. Apply the membrane to the bottom of the flange. The
drain should be fully supported, without movement, and should be
even with the plane of the substrate. Apply the RedGard membrane
around drain. Embed a 12" x 12" (30 x 30 cm) fiberglass mesh into the
membrane, making sure it does not obstruct the drainage weep holes.
Then apply an additional coat of the membrane and smooth. After
curing, clamp the upper flange onto the membrane and tighten. Use a
silicone caulk around the flange where the membrane and the upper
flange make contact. A toilet flange can be handled in much the same
manner.
RedGard® as Crack Prevention Membrane
Force RedGard® into cracks with the flat side of the trowel, roller or
brush. Using a 3/16"-1/4" (5-6 mm) V-notch trowel or 3/8" (9.5 mm)
rough textured roller. Use the flat side of the trowel and flatten the
ridges to form a continuous, even coat of material. The membrane
should extend a minimum of the diagonal measurement of the tile
beyond both sides of the crack. Gaps between plywood sheets and
where floors meet walls must also be prefilled. For continuous crack
isolation, cover the entire substrate with RedGard® applied to a
minimum 30 mils wet-film thickness.
RedGard® as General Waterproof Membrane (ANSI 118.10)
Cracks to 1/8" (3 mm) should be prefilled before beginning the
waterproofing application. Lightly dampen all porous surfaces. Use a
3/4" (19 mm) rough-textured synthetic roller or a 3/16"-1/4" (5-6 mm)
V-notch trowel and heavily pre-coat the corners and the intersections
where the floors and walls meet, extending 6" (15 cm) on either side.
RedGard® applied in the above manner meets requirements of ANSI
A118.10 without fabric reinforcement. For extra protection, embed a
6" (15 cm) wide fiberglass mesh into the membrane for changes of
plane and for gaps 1/8" (3 mm) or greater. If using a trowel, spread
thematerialwiththetrowelheldata45°angle,andthenflattensthe
ridges. If using a roller, apply a continuous, even film with overlapping
strokes. An airless sprayer may be used for the waterproofing
application. The sprayer must produce between 1900-2300 psi, with a
flow rate of 1.0-1.5 GPM and must have a tip orifice size of 0.025-
0.029. Apply a continuous film with overlapping spray. The membrane
appearance is pink when wet and dries to a dark red color. It typically
takes 1-1.5 hours to turn completely red. After the first coat turns red,
inspect the film for integrity and fill any voids or pinholes with
additional material. Apply a second coat at right angles to the first
coat. Periodically check the film thickness with a wet-film gauge.
Combined dried coatings must be at least 30-35 mils thick. When wet,
the combined coatings must be at least 60-70 mils and must not
exceed 125 mils wet-film thickness.
Curing of Product
RedGard® is dry when it turns solid red, with no visible pink color.
Typically, drying time is 1-1.5 hours; depending on ambient conditions,
drying time can be as much as 12 hours. After the second coat is
applied and both coats are fully cured, the application area can be
flood tested.
Protection
If tile or stone will not be set immediately after curing, protect the
application from rain, direct sunlight and inclement weather for 72
hours after application. If delays longer than 72 hours are expected,
cover the area with felt paper. Care should be taken to prevent the
application from becoming soiled or punctured during and after
application.
