Product Overview Protect your tile and stone installations with Custom Building Products RedGard 3.5 Gallon Waterproofing and Crack Prevention Membrane. This premium, ready-to-use elastomeric liquid-applied membrane creates a continuous, commercial-grade moisture barrier. Formulated for maximum durability, RedGard prevents water damage and isolates shrinkage cracks up to 1/8" (3 mm) before they can ruin your finished floor or walls. Whether you are building a custom tile shower, preparing a subfloor, or sealing a steam room, RedGard dries quickly in just 60 to 90 minutes. It features a distinct color-cure indicator, turning from a wet pink to a solid, vibrant red when it is fully dry and ready for tile installation.

Why Professionals Choose RedGard:

• Dual-Action Protection: Functions as both an ANSI A118.10 waterproofing barrier and an ANSI A118.12 crack isolation underlayment.

• Color-Curing Technology: Changes color from pink to dark red to signal when the membrane is ready for layout and thin-set application.
