About Rust-Oleum AMW Mould Removal Solution

AMW is a fungicidal wash; a solution of an approved biocide in water.

It is used as a masonry and roof surface fungicidal wash for professional use against mould, fungi, moss, etc.

HSE Approval No 4246.

Surface Preparation

All mould, fungi, lichens etc. should be given a saturated coat of AMW to kill spores.

Remove debris by power washing or with a stiff brush.

The whole area should then be given a second coat of AMW and allowed to dry (to render the substrate sterile).

Application and Thinning

Apply 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.

If affected by heavy rainfall within 4 hours of application, re-apply.

Ensure residues are substantially diluted with water before entering drains etc.

Use a brush or “coarse” spray such as a pneumatic garden spray. Do not dilute.
