Brutus Aqua Bar B Tile Underlayment Roll 500 sq ft

The Brutus Aqua Bar B Tile Underlayment Roll is a premium moisture vapor retarder designed to protect interior floors and surfaces from moisture damage. Constructed from two layers of durable Kraft paper laminated with asphalt, this non-reinforced Grade B paper provides a reliable barrier against moisture migration. Its 30/30/30 duplex construction ensures long-lasting performance in high-moisture environments.

Ideal for ceramic, porcelain, stone, and wood flooring installations, the Aqua Bar B Underlayment is perfect for use over cement board, plywood, or concrete subfloors. It also serves as an effective membrane for walls, countertops, and residential showers. The 500 sq. ft. roll (3 ft. x 167 ft.) offers ample coverage for large projects, helping to prevent buckling, cupping, and cracking caused by excess moisture.
