When tile installations require durable, proven protection, count on RedGard Waterproofing and Crack Prevention Membrane - from Custom Building Products.

Redgard is a ready to use elastomeric membrane with outstanding adhesion.

Liquid-applied RedGard delivers monolithic coverage and creates a seamless barrier over areas of any size or shape.

Third party laboratory testing proves that RedGard Waterproofing and Crack Prevention Membrane outperforms competitive products.

Tough enough to meet a variety of rigorous building codes, RedGard exceeds ANSI A118.10 and IAPMO requirements as a shower pan liner.

RedGard is ideal for use in steam showers.

It’s the first liquid-applied membrane to surpass the TCNA standard for a low perm moisture vapor barrier.

RedGard also delivers robust crack isolation to protect large format tile, stone and grout.

This versatile membrane carries an extra heavy duty service rating for the most demanding commercial projects.

Before getting started, consult the Technical Data Sheet.

RedGard is fast and easy to apply with a nap roller, trowel or an airless sprayer.

All surfaces must be clean, dry and structurally sound.

Ensure that exteriors and wet areas have properly angled floors, sloped ¼” per foot to drains.

On shower floors, Custom recommends applying the waterproofing membrane over the mortar bed.

For waterproofing wet areas, always apply two coats of RedGard.

When waterproofing a shower, pre-treat corners and changes of plane where floors and walls meet.

Spread RedGard six inches on each side of the intersection.

Always apply the membrane to the bottom drain phalange for continuous coverage.

Embed 6-inch wide fiberglass mesh tape at drain transitions and to reinforce any gaps over 1/8th inch.

Allow these pre-treated areas to cure, then complete the first coat, beginning with the walls.

For general waterproofing, apply both coats at a rate of 110 SF per gallon.

For shower pan protection, use a coverage rate of 40 total SF per gallon, or 80 SF per coat.

The key to optimum coverage is applying RedGard in smooth, overlapping strokes.

If using a trowel, spread with the v-notch side held at a 45 degree angle and then flatten the ridges.

Consult the Technical Bulletin before using an airless sprayer.

You’ll know RedGard is dry when it turns from pink to red.

This typically takes 60-90 minutes. Actual cure time depends on jobsite conditions.

Before applying the second coat, cover any voids or pinholes.

Spread the second coat of RedGard at a right angle to the first.

Allow each coat to fully cure between steps and before flood testing or setting tile.

For general crack isolation, apply one coat at up to 100 SF per gallon.

Apply two coats at 50 SF per gallon, per coat to provide ANSI A118.12 protection.

Fill shrinkage cracks up to 1/8” wide by forcing RedGard into the crack with a trowel.

To isolate tile from the crack, the membrane must extend at least three times the tile’s width across the crack on the floor.

Periodically check the coverage rate or mil thickness to ensure an accurate film depth.

After application, protect the membrane from sunlight, soiling and punctures if tile will not be installed right away.

Do not apply RedGard if the temperature will fall below 40 degrees within 72 hours.

Always follow TCNA detail EJ171 for proper movement joint placement.
