DESCRIPTION Bituminous Primer is product containing oxidized bitumen and a mix of technical quick drying solvents. APPLICATION Bituminous Primer is recommended to block the dust and the porosity of concrete surfaces allowing the quick application o f the bituminous polymer membranes, both with flame application and cold bonding with bituminous sealants or with self adhesive membranes.Bituminous Primer allows quick film drying, has an excellent penetration and adhesion to the support for the absence of surface stickiness. INSTRUCTIONS FOR USE Concrete surfaces must be dry, clean and free from oil, dust or release agents. This type of primer is ready for use after mixing it. Bituminous Primer can be either sprayed or applied by means of roller or brush. In case of hot application of membranes with flame, the primer can be used only if surfaces are completely dry. On the contrary, if the surface is damp, it is recommended to use a bituminous primer specific for damp surfaces. The drying time depends on concrete porosity, on the quantity of product applied and on the temperature of both the surface and the environment. Usually the film gets dry after 2-4 hours from the application. The drying time can increase in case of cold temperature and with low a bsorption surfaces. PACKING 5 gallon Bucket SHELF LIFE The product can be stocked in closed buckets and in dry area, far from UV rays for 12 months. TOOL CLEANING After use clean tools with common solvents.
