Urethane Membrane Choice
Urethane membrane systems offer flexible, elastomeric protection for concrete, metal, and wood substrates. Choose a two component polyurethane or moisture cured system based on substrate condition and climate. Evaluate cure time, VOC levels, and UV resistance to prevent future maintenance headaches.
Primer compatibility matters for strong adhesion and long service life. Match the primer to substrate porosity and moisture level for reliable bonding. Consider surface preparation steps like cleaning, drying, and minor repairs before coating.
Roof and Wall Install
Preparation lays the foundation for a durable urethane seal. Ensure surfaces are clean, free of dust, oils, and moisture before application. Address cracks and movement joints with compatible primers and sealants.
Application methods include spray, roller, and trowel techniques for roofs and exterior walls. Control temperature and humidity within the manufacturer recommended range to optimize cure. Follow a staggered pattern to avoid lap gaps and ensure continuous coverage.
Bathroom Waterproof Steps
Bathrooms require meticulous detailing around drains, walls, and floor transitions. Install a proper slope, install a waterproof base, and seal joints with urethane compatible sealants. Choose elastomeric coatings that resist humidity, soap scum, and chemical cleaners.
Seal penetrations such as pipes and vents with compatible gaskets and beads. Keep expansion joints free of laitance and apply reinforcement fabrics where needed. Test the system with submersion or water spray to verify seal integrity.
Maintenance and Checks
Regular inspection helps catch microcracks and peeling before they widen. Schedule periodic reviews after heavy rainfall or temperature swings. Recoat or repair sections based on solar exposure and material wear within recommended intervals.
Document coating histories and soil or moisture conditions to plan future maintenance. Educate residents in Bundang leakage prone zones about signs of water intrusion. Adopt newer polyurethane systems with improved UV stability and faster cures when upgrading.
