Enhances the bond strength of Seal It Liquid Membrane and Easiseal Pro to bitumen based, asphalt and felt substrates. Quick and easy to use. Blocks surface staining from bitumen coatings.
Temperature during application of primer must be above 5oC. Apply a single coat of Seal It Bleed Blocker / Primer to the surface with a brush or roller. Follow coverage rate to ensure minimum thickness is achieved. Leave to fully cure, normally overnight, in cold weather it may require 48 hours to fully cure. It is essential that bituminous materials are completely covered with Seal It Bleed Blocker / Primer prior to application of Seal It Liquid Membrane. Particular care must be given to rough surfaces such as bitumen felt, where any gaps in primer coverage can lead to product failure. Two coats of Seal It Bleed Blocker / Primer are required on uneven surfaces and over any bitumen based coatings. Allow each coat to dry fully before overcoating.
Continue with the application of Seal It Liquid Membrane or Easiseal Pro as per the Technical Datasheet/packaging details. It is recommended that Seal It Reinforcing Mat is bedded into the Seal It Liquid Membrane to extend the lifespan of the product over bitumen substrates.
