Application steps

APPLICATION INSTRUCTIONS

Care needs to be taken over preparation of surfaces before application. All surfaces must be free from oil, dirt, dust and loose debris. On metal surfaces all loose rust should be removed using a wire brush and where advanced signs of corrosion are evident the area be treated with a rust inhibitor. Surfaces should be dry for best results, although Bitumen Primer will adhere to damp, but not wet surfaces. Apply using a suitable brush or roller. Bitumen Primer is resistant to rainfall within 20-30 minutes of application.

CLEANING OF TOOLS

Tools may be cleaned with white spirit. Minor spillages should be wiped off surfaces before the compound has set.
Major spillages should be mopped up immediately with an inert, absorbent material, such as sand and disposed of in accordance with regulations.
