Ensure the substrate is structurally sound, free of surface laitance, oils, grease, dirt, moss, lichen, and loose material.
The surface should be smooth and free from sharp projections and loose debris, and any material which would hinder adhesion.
Apply by brush or roller ensuring the primer is well applied into the surface. Apply a thin coat and avoid pooling. Allow to dry thoroughly before over coating. The surface of the primer remains tacky when dry.
Protect from rain and frost until dry.
Once dry ensure the primed surface is kept free of dust prior to the application of the bituminous membrane.
