This layout balances a persuasive overview for DIYers with the hard technical facts that professional installers look for before making a purchase.

Product Overview Ensure a permanent, moisture-tight seal on smaller tiling projects with Custom Building Products RedGard 1 Gallon Waterproofing and Crack Prevention Membrane. Ideal for powder rooms, accent walls, kitchen backsplashes, and shower repairs, this ready-to-use elastomeric liquid creates a seamless, commercial-grade water barrier. RedGard isolates shrinkage cracks up to 1/8" (3 mm) to keep your subfloor movement from snapping or cracking your finished tile and stone layout. Formulated with rapid color-cure technology, the liquid changes from a wet pink to a solid, deep red when it is fully dry—taking the guesswork out of your installation timeline.

Why Professionals Choose RedGard:

• Advanced Color-Curing: Visually transitions from pink to a solid red so you know exactly when the surface is ready for thin-set and tile placement.

• Anti-Fracture Protection: Meets strict ANSI A118.12 standards to prevent substrate cracks from telegraphing up into your expensive ceramic or porcelain tile.

• Smooth, Multi-Surface Application: Easily roll, brush, or trowel over concrete slabs, cement backerboards, exterior-grade plywood floors, and existing masonry.
