Application of Product
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.

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atarate
of 100 sq. ft. per gallon. To meet the requirements of ANSI A118.12,
apply two coats of RedGard at a rate of 50 sq. ft. per gallon each coat.
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) roughtextured synthetic roller or a 3/16"-1/4"
(56 mm) Vnotch trowel and heavily precoat the corners and the
intersections where the floors and walls meet, extending 6" (15 cm) on
either side. 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. Apply RedGard at a rate or 110 sq ft per gallon each
coat. 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 19002300 psi, with a flow rate of 1.01.5 GPM and must have
a tip orifice size of 0.0250.029.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. To meet the requirements
of IAMPO, Two coats should be applied at a rate of 80 sq. ft. per
gallon each coat. In all cases the wetfilm thickness should not exceed
125 mils.
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 heavy traffic damage. Protect from rain 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.
