Rooftop Urethane Install
Rooftops face sun, rain and thermal cycling, making polyurethane waterproofing a practical choice. Thorough substrate preparation is essential, including cleaning, drying, and repairing cracks to ensure adhesion. Consider spray-applied urethane or polyurea systems designed for UV exposure and rooftop traffic.
Moisture levels must be controlled before application to prevent blistering. Prime substrates appropriately for concrete, metal, or asphalt to optimize bond. Follow recommended cure times and schedule work in mild weather to avoid quality loss.
Exterior Wall Sealing
Exterior wall sealing begins with removing flaking coating and repairing visible cracks. Select weatherproof membranes compatible with the wall substrate and flashing details. Proper surface profiling enhances adhesion and long term performance.
Install seams and joints with compatible sealants to handle expansion and contraction. Guard against wind-driven rain by detailing drip edges and sill pans. Conduct a dry and wet adhesion test after installation to verify performance.
Bathroom Waterproofing
Bathroom waterproofing demands a continuous barrier behind tiles and fixtures. Choose polyurethane waterproofing systems suitable for concrete or gypsum boards. Ensure proper drainage and slope to minimize standing water.
Carefully abut corners, joints, and penetrations with compatible sealants. Perform water tests after curing to confirm no leaks. Regular ventilation helps keep humidity in check and extends coating life.
Maintenance and Longevity
Maintenance and longevity rely on periodic inspection and timely recoating. Schedule visual checks after heavy rains and during freeze thaw cycles. Address any UV chalking or color fading by applying a fresh coat before damage spreads.
Document coating thickness and surface condition to plan next maintenance. Store materials under recommended conditions to preserve flexibility. With proper care, urethane waterproofing protects structures and preserves value.
