Question 1

What surfaces can BE-50 be applied to, and is surface preparation required?

Accepted Answer

BE-50 is suitable for concrete, masonry, brick, and prepared steel substrates. Surfaces must be clean, dry (or slightly damp for concrete — consult TDS), and free from oil, loose particles, and standing water. Concrete surfaces benefit from mechanical cleaning or acid etching before application to improve bitumen penetration and adhesion.

Question 2

How does a waterborne bituminous emulsion primer differ from solvent-based bitumen primer?

Accepted Answer

Waterborne BE-50 uses water as the carrier, making it low-VOC, non-flammable during application, and safer for confined spaces like basements and service tunnels. Solvent-based bitumen primers penetrate porous surfaces slightly faster and have better performance on damp substrates, but are flammable and require adequate ventilation. BE-50 is the preferred choice where environmental and safety regulations restrict solvent use.
