Urethane Waterproofing
Urethane-based waterproofing forms a seamless membrane that resists cracking under movement. It bonds well to concrete, metal, and tiled surfaces common in boiler rooms and rooftop decks. Proper substrate prep, including cleaning and moisture control, is essential for long-lasting adhesion.
For boiler rooms, choose moisture-curing or solvent-based systems suitable for high humidity and heat exposure. A primer improves adhesion on rough or dusty surfaces and reduces pinholes. Applying two coats with a brief cure interval creates a robust, flexible layer that bridges expansion joints.
Roof Wall Applications
When using urethane waterproofing on roofs and exterior walls, start with a dry, sound substrate. Moisture in the base can trap air and undermine adhesion, causing leaks around penetrations like vents or boilers pipes. Topcoats add UV resistance and abrasion protection for long-term performance.
For boiler-related projects, ensure parapet flashing and pipe penetrations are sealed with compatible urethane systems. Use reinforced fabric or mesh at joints to prevent cracks from thermal cycling. Construction crews should follow cold-weather handling guidelines to prevent premature curing.
Basement Bathroom Tips
In basements and bathrooms, moisture control is critical for preventing mold and costly leaks. Polyurethane coatings adapt to curved surfaces and corners around sinks and showers, offering seamless waterproofing. Regular inspection helps catch micro-cracks before they widen.
In boiler areas, protect condensation lines and floors from water damage during boiler repair or maintenance. A continuous membrane reduces capillary wicking and damp spots under cabinets. Consider moisture meters and leak detectors to monitor hidden areas.
Maintenance and Care
Maintenance involves periodic inspection, cleaning of debris, and re-coating every 5-7 years depending on traffic and exposure. Inspect edges around windows, vents, and fixtures where leaks tend to start. Address any delamination or blisters promptly with a fresh application.
In winter, check for freeze-thaw damage near boiler rooms and exterior walls. Clearing frost and insulating piping reduces stress on the waterproof layer. Keep a simple plan for repairs and store contact info for licensed technicians specializing in boiler repair.
