- Surfaces should be dry for best results, although Bitumen Primer will adhere to damp but not wet surfaces
- Bitumen Primer should be applied by brush ensuring an even coat with no pooling, or applied evenly by airless spray

- Minor spillages should be wiped off surfaces immediately before the product has set
- Major spillages should be mopped up immediately with an inert, absorbent material, such as sand and disposed of in accordance with regulations
