Application & selection notes
For hot, dry site conditions, check substrate temperature, moisture, working time and curing before application. The heat resistance of a cured membrane does not permit installation outside the application limits in its TDS.

Send the project location or destination port, application, substrate, required thickness, area in m², quantity and delivery schedule. Request the selected grade, export packing, TDS and batch documentation for consultant review. Manufactured in China; project approvals are reviewed for each enquiry.

BIOGO-S is a liquid-applied PU waterproof coating that cures into a continuous elastic membrane. It is not polyurethane insulation foam. Use the selected grade for protected or non-exposed waterproofing assemblies and follow its substrate preparation and curing requirements.
Treat corners, drains, pipe penetrations and joints before coating the main area. Build the specified membrane thickness in the required coats and allow curing before protection or subsequent work. Consumption depends on thickness and substrate condition.
An exposed roof requires an explicitly suitable UV-resistant system. Compare BIOGO-ES when the coating must remain exposed to sunlight; do not assume every PU waterproof coating has the same exposure rating.
