ALSAN Coating Asphalt Bleed Blocking Primer is a VOC compliant single component plasticizer free water based acrylic primer/basecoat used to enhance adhesion and block bleed through discoloration from asphalt and asphalt based substrates such as BUR, modified bitumen and asphalt cap sheets.
ALSAN Coating Bleed Blocking Primer can be applied using single component airless spray equipment, roller or brush. Prior to starting application, perform an adhesion test on each surface type to ensure adequate bond can be achieved or if another primer or other specific surface preparation is required. Do not apply over wet substrates or with risk of precipitation. Protect from freezing during transit, handling, storage, and installation.
