Usage & Highlights
- Officially HSE-approved biocide, HSE approval no. 9225
- Does not smell & non-hazardous to work with
- Does not attack glass or PVC
All mould, fungi, lichens etc. should be given a saturated coat of AMW before their complete removal (to kill spores). Remove debris by power washing or use of a stiff brush. The whole area should then be given a second coat of AMW and allowed to dry (to render the substrate sterile).
Apply Rust-Oleum AMW abundantly, preferably by brush, and wait 12 hours. Dry-brush and remove dust prior to painting, or clean with high-pressure water and let the surface dry. Affected by heavy rainfall for at least 4 hours after application. If doubtful re-apply. Ensure residues are substantially diluted with water before entering drains etc. Tools: Brush or “coarse” spray such as a pneumatic garden spray. Do not dilute.
