Capaproof PLUS

Additive for single layer application of CAPAPROOF PU membrane

  • Special additive for single layer application of CAPAPROOF PU membrane

CAPAPROOF PLUS is an additive that gives the CAPAPROOF PU single-component polyurethane membrane several properties, including single-layer application without internal bubbling, improved physical-mechanical properties and faster initial drying. It is ideal for the application of CAPAPROOF PU in low temperature or adverse weather conditions, while improving the mechanical performance of the membrane.

Capaproof PLUS

Its main uses are as follows:
• It allows the application of the CAPAPROOF PU membrane - a liquid polyurethane membrane - in a layer of the desired thickness (e.g. 2 mm) in one go, doing away with the need for successive layers and eliminating intermediate drying times and rain hazards.
• Elimination of bubbling and other membrane effects CAPAPROOF PU when applied in a single application.
• Increases the tensile strength of the solid membrane formed, giving it more persistence
• In approximately 90 minutes, the mixture creates a skin surface, avoiding problems in case of rains ("mixing life").
• The initial drying process of the CAPAPROOF
PU membrane is approximately 3 hours.
Note: consult our technical department for application on other types of substrates or settings


Metal packaging kits with the format: 2 l (1.7 kg)


The mandatory consumption for the system to be viable is fixed and invariable depending on the CAPAPROOF PU format to be used: 2 l (1.7 kg) per 25 kg of CAPAPROOF PU.


12 months at a temperature of 5 oC to 35 oC, always stored in dry places. If the container is opened it should be used immediately.


The recommendations for use are based on our knowledge and experience. The technical data have been obtained under normal laboratory conditions and may vary depending on the conditions of installation. As the conditions of application are beyond our control, the information in this sheet does not imply any liability on the part of the company.
