Gripset Xpress Primer H20 Plus
A unique 1 component vapour barrier primer designed for use on concrete, screeds and mineral surfaces. Primer H20 Plus forms a vapour barrier to prevent blistering and delamination of membranes associated with residual dampness and surface moisture
Xpress Primer H20 Plus is a unique 1 component vapour barrier primer designed for use on concrete, screeds and mineral surfaces. Primer H20 Plus forms a vapour barrier to prevent blistering and delamination of membranes associated with residual dampness and surface moisture
Outstanding penetrating and adhesion properties once dried Primer H20 Plus will enhance the adhesion of overlaid coatings and finishes.
With its fast drying properties, this unique vapour barrier forms a unique colour-changing effect while drying. It is applied as a milky white liquid and creates a light green tinge during the drying phase before becoming clear in its fully dry state when it is ready to be overcoated. Unlike traditional vapour barrier coatings, once cured, the Primer H20 Plus will not change the surface properties of concrete and mineral surfaces, ensuring membranes and adhesives will bond as designed.
Primer H20 Plus can be applied to damp surfaces. In addition to performing as a vapour barrier on surfaces with residual moisture, it will prevent concrete carbonation, providing outstanding anti-degradation properties. When used on screeds and renders, it reduces the phenomenon of efflorescence forming in the mineral surface.
Features & Benefits
- Forms a Vapour Barrier against residual moisture
- Can be applied over damp and green concrete and mineral substrates
- Fast drying, enabling application of finishes after only 1 hour
- Water-resistant
- Unique colour-changing formulation indicating when product is ready for overcoating
- Reduces incidents of efflorescence when used over screed bases
- Designed to use with Xpress Multi Pro Membrane on porous surfaces
- Fully compatible with Gripset membranes, tile adhesives, water based vinyl and flooring adhesives, renders, mortars and acrylic paints and texture coatings.
- Economical surface coverage of up to 1 litre/8m2 .
- Can be used as an exposed protective sealer over concrete against carbonation and general degradation
- Suitable for internal and external applications.
Substrates
Substrates suitable for application as a vapour barrier include:
- Concrete, masonry surfaces, renders, screeds.
- Concrete blocks and aerated concrete
- Cement sheeting, plaster board and general wet area linings
- Absorbent surfaces
Application and Coverage
- Apply 1 x coat at coverage of 1itre per 6-8m2
- Can be applied by brush, short/medium nap roller or airless spray
- Check porosity of surface with water droplet test. If droplets do not absorb, the surface is non-porous and will need to be prepared by grinding, etching or other abrasive means to open surface pores
- Primer can be overcoated once the film is clear and tack-free
