PU 280 Moisture Barrier Primer 11 kg – High-performance polyurethane resin for screeds and concrete
The PU 280 Moisture Barrier Primer 11 kg is a high-performance professional solution designed to effectively prepare, strengthen and protect substrates prior to the installation of floor coverings. Ideal for both renovation and new-build projects, it acts both as an adhesion primer and as a barrier against residual moisture.
High-performance polyurethane primer for demanding substrates
Formulated with polyurethane resin, PU 280 is ready-to-use and applies easily to both absorbent and non-absorbent substrates. It enables you to: Its versatility makes it an indispensable ally for professionals in the building and floor preparation sectors, particularly in technical or challenging environments.
- Improve the adhesion of flooring systems.
- Strengthen brittle screeds, damaged edges or crumbling areas.
- Level surfaces before applying floor coverings.
An effective moisture barrier without the need for prior testing
PU 280 acts as a genuine capillary rise barrier, minimising the risks associated with moisture in cementitious and concrete substrates. It is compatible with: It can be applied without prior moisture measurement, which saves a considerable amount of time on site.
- Cement screeds without underfloor heating: up to 6 CM% / 98% RH.
- Cement screeds with underfloor heating: up to 6 CM% / 85% RH.
- Concrete screeds: up to 7.5% by mass / 98% RH.
Quick and easy application
- Apply using a primer roller or a short-pile velvet roller.
- Coverage:
- As a primer: approximately 100 to 150 g/m².
