Aspect
Liquid
Water-based fixative primer, formulated with bitumen in water emulsion and special additives, with high dry content values. It blocks the dust and porosity of concrete surfaces. Promotes the adhesion of polymer bitumen membranes by granting a good anchorage. It has excellent adhesion and penetration on every dry concrete surface, but also on slightly damp surfaces. It is odourless, non-flammable, non-toxic and solvent free.
Make sure the surface is free from detached parts, loose debris or non adherent parts, coatings, rust, powder, disarming oils and carefully clean the surfaces so that they become sound and dry. Do not apply is bad weather is forecast as this could negatively influence the correct drying time.
RABITUM PRIMER can be applied by brush, roller or spray.
Slightly mix before use. Dilute up to 20-25% of water
To clean the tools use common synthetic or nitrous diluents
Do not use RABITUM PRIMER;
The polymer-bitumen membranes can be applied on the concrete, painted with the primer, only when the primer coat is perfectly dry.
The consumption is strongly influenced by the porosity and consequently by the absorption of the surface. The average consumption is of 100÷200 g/m² on metal surfaces, of 150÷300 g/m² on concrete.
