JUTA GP® (quick drying) Primer is a low viscosity primer reduced with an aromatic hydrocarbon. It is black in colour and highly mobile. It is modified to provide improved damp substrate tolerance and membrane bonding relative to non-modified bituminous primers.Read More
- Can be applied directly onto green concrete, masonry, metal and wood.
- Drying performance at 30-60 mins is far superior to water-based systems or primers using aliphatic solvents.
- Suitable for application in temperatures as low as freezing point.
GP® Primer seals porous substrates and encourages the adhesion of bituminous waterproofing systems and sheet coverings. It may be applied successfully to a wide range of surfaces:
- Metals (mild steel, Zinc, Lead)
- Lightweight concrete screeds
- Asbestos cement
GP® Primer is available in 5 litre and 25-litre containers.
Handling and Storage
GP® Primer is not chemically sensitive to heat or cold but extreme temperatures should be avoided. The product should be stored in well-maintained storage tanks
All components are REACH (Reg. (EC) No 1907/2006) registered. The product does not contain any Substances of Very High Concern (SVHC).
Toxicity and Safety
GP® Primer is classified as hazardous according to CLP Regulation (Reg. (EC) No 1272/2008). Refer to the Product Safety Data Sheet for recommended safety precautions. It is recommended the end-user wear safety glasses, safety gloves and protective clothing during application. Avoid direct contact with skin and eyes. Do not eat, drink or smoke while handling or using the product.View Data Sheet
All surfaces should be smooth, clean, sound and free from oil, grease, condensation and other contamination. Product may be applied to ‘green’ concrete and damp surfaces. The minimum ambient temperature for application is 0°C; it is not recommended to apply GP® Primer at temperatures below this as advertised drying times will not be achieved.
GP® Primer is recommended to be brush or roller applied, avoid pouring directly onto a horizontal surface. This may cause puddling during application and increase drying time. GP® Primer should not need to be thinned if recommended storage conditions have been maintained.
Coverage rates depend on porosity of surface:
- Porous surfaces (e.g. concrete, wood): 6-8 m2/litre
- Non-porous surfaces (e.g. steel): 11m2/litre
GP® Primer is designed to be effective as a single cost application.
If applying to metal, ensure the surface is well prepared in advance. Wire brush off any rust and ensure clean and dry. Where long-term protection is required, treat with a rust-inhibitive product. Consult the Technical Department for advice on compatibility prior to application if unsure.
Keep primed areas clean and dust-free so far as possible prior to membrane application. Areas that accumulate significant amounts of dust or dirt must be re-primed before the membrane application, bonding performance will be compromised by debris.
For cleaning tools use hydrocarbon-based solvent such as White Spirit. Xylene, Toluene and Acetone are also effective.
