Hammerite Kurust Blister is a water-based rust-converter primer to stabilise rust prior to topcoat application.
Clean surface by removing all loose paint and rust, dirt, grease and salt. Rinse with clean water and allow time to dry. Note: Special precautions should be taken to avoid inhalation of dust during surface preparation of pre-1960’s paint surfaces as they may contain harmful lead.
Shake container well and pour required amount into a plastic container. By brush: apply direct to rusty area, working well into heavily pitted areas, corners and edges. Avoid coating onto painted areas. Hammerite Kurust will turn blue/black when reacting with rust. If it does not change colour in 1 hour re-apply. Apply topcoat after 3 hours. Do not replace unused Kurust back into the original container.
Clean container with water. Hammerite Kurust should be stored in a dry, well-ventilated area. Protect from frost and direct sunlight.
