A water-based primer used to prepare asphalt / bitumen surfaces and roofing felt prior to application of the Liquid Membrane.
Although the Liquid Membrane can be used on most building substrates such as concrete, timber and metal without primer, there is an adverse reaction when used on top of traditional black bitumen.
The Primer enhances the bond strength of the top coat and prevents bitumen substrates from staining through.
Available in 0.66 gallon tin.
Apply by roller or brush.
