As well as its uses as a waterproof paint, bitumen can also be used as a primer for a roof. At ERoofing, we stock top-shelf bitumen primer from Cromar, Everbuild, and Bond-it. Whatever sort of bitumen primer you need, you can find it here.
Generally, we recommend applying Bitumen Primer with a 4-inch or 3-inch brush ensuring an even coat with no pooling. In some circumstances, it may be applied with an airless spray.
Bitumen primer is used to prepare surfaces, especially porous surfaces, to have other bituminous layers applied over them. This can be bitumen paint for instance or shed felt with bitumen applied on one side.
In addition, some types of bitumen primer are perfect for preparing a surface to receive flashing from non-lead lead alternatives. At ERoofing we have a large selection of lead alternatives to choose from that are perfect to use alongside bitumen primer.
