Mapei Mapelastic WaterStop Liquid Membrane (1 gal.)

Description

Mapei Mapelastic WaterStop Liquid Membrane (1 gal.) is a professional-grade, elastomeric waterproofing and crack-isolation membrane designed for use under ceramic tile, porcelain tile, and natural stone. Applied as a liquid, it dries to form a flexible, seamless membrane that protects substrates from water penetration while accommodating minor movement. Mapelastic WaterStop is ideal for wet areas such as bathrooms, showers, kitchens, and laundry rooms. Its easy roll-on or trowel application allows installers to create a continuous barrier without seams or fabric reinforcement. Once cured, it provides dependable waterproofing and helps reduce the risk of cracks telegraphing through tile installations, making it a trusted solution for long-lasting results.
