Specifications
Technical documents and conditions of use
See the technical documents below for specification sources and conditions. Verify the exact grade and document version before application. Specification sources
This document covers the relevant product series. Confirm the exact model, substrate preparation, mixing ratio, dry film thickness, temperature, humidity, curing and test conditions. Typical series values are not guaranteed values for every application.
Verify performance and service-life statements against the relevant reports, specimen preparation, test standards and service conditions. Service-life figures without supporting reports are not durability guarantees; site photographs do not replace film-thickness testing or project acceptance records.

Features
- Evaluate weathering performance for the selected grade, color and film thickness.>Inspect and maintain exposed coatings according to project conditions. Confirm whether a protective layer is required.
- Coating flexibility can help accommodate limited substrate movement. Repair cracks and detail joints before coating; structural movement requires a separate design.
- Waterproofing depends on substrate preparation, specified film thickness and detailing. Conduct the project-specified water test after full cure.
- Review the grade-specific SDS, emissions data and ventilation requirements before use. Wear appropriate protective equipment during mixing and application.
- Select corrosion protection according to the actual chemical medium, concentration, temperature and exposure. Confirm suitability by testing and establish an inspection and maintenance plan.
- For vertical surfaces, confirm sag resistance, thickness per coat and finish on a sample area.
Applications
Waterproofing of exterior walls, exterior repair, exterior protection of industrial buildings, waterproofing of new energy buildings
