Bitumen Primer * Bitumen Primer is Bituminous air curing ready mixed Acid & Alkali resistant special primer. Application * Concrete surface must be clean, dry and rough. No primer should be applied over smooth and wet surface. * After cleaning the concrete surface, one coat of Bitumen Primer should be applied with brush and allow to dry thoroughly. * The drying time will depend upon the temperature. * 24 Month at the temperature 30C (+2OC) Packing * Bitumen Primer: 25 Liter Drum Note * Bitumen Primer contains volatile and slightly toxic solvent. Keep away from spark and open flames at working area. * Bitumen premier it is manufactured using bitumen solution which is used for sealing of prime porous and non-porous surface, and also to protect residential and commercial building. * Bitumen Primer is used to protect substrate against corrosive attack, is suggested to apply anti-corrosive primer.It is best for protection against sub-striate against atmospheric corrosion and chemical corrosion. It is a mixed substance made up of organic liquids that are highly sticky, water proof, viscous,acid proof as with all surface coating, good Bitumen Premier is used for long life of the system. it is applied by brush or roller and allowed to dry before any water proofing treatment so to avoid solvent it is used in defects such as cracks, broken mortar joints, etc. are to be repaired prior to Bitumen primer application.
