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

A system application handbook is available; an individual TDS or SDS for this product has not been supplied. Use the handbook for system selection only. Confirm the specification, film thickness and acceptance criteria with the technical team for the exact model and service conditions.

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

  • Fits hidden and semi-hidden scenes, such as basement floors, side walls, roofs, etc., to protect the basement from erosion in a dark and humid environment, taking into account long-lived water and structural protection
  • 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. Drinking-water or food-contact applications require specific evidence and approval for the intended use.
  • Select the coating according to actual mechanical loads, chemical media, concentration, temperature and exposure. Confirm suitability by testing and establish an inspection and maintenance plan.

Applications

Waterproofing of various types of building basement floors, side walls, roofs, waterproofing of basements, underground pipes, tunnels, etc.

Storage

This product is combustible. Store at or below 40 degrees Celsius in a cool, dry, ventilated place away from ignition sources. Shelf life: one year.

Selection guide

Basement waterproofing selection centers on concealed areas, groundwater ingress and minor structural movement. This product targets slabs, side walls, overhead slabs and associated underground facilities; compare impermeability, concrete adhesion and prolonged damp exposure rather than exposed-finish appearance.

Formulation notes

Basement areas differ in water-ingress conditions and application access. Define substrate condition, cracks and detail treatment before confirming the coating system. The material’s waterproofing parameters do not replace waterproofing design for the specific location.
