Technical Data Sheet


Dekade water based Rust & Metal Primer is a modified acrylic based corrosion inhibiting primer. Ideal for rusted surfaces which include galvanised iron roofs, metal doors, window frames, handrails, gates, posts, farm implements, etc.

Easy application properties provide good flow and levelling. Excellent sanding and intercoat adhesion properties. Application equipment easily cleaned in water. No obnoxious fumes. Lead free. Non toxic.

New Work:
Galvanised Iron: Thoroughly clean with Scotchbrite pads and Dekade Galvanised Iron Cleaner. Repeat this procedure until a water break free surface has been obtained.
Ferrous Metals: For best results abrasive blast to SA 2.5 of the Swedish Standard. Alternate but less effective: Prepare steel by wire brushing.

Previously Painted Surfaces:
Sand, scrape, chip etc. to remove all loose flaking surface rust, mill scale and existing paint. Wash down with Dekade Trade Degreaser to remove oil, grease, salt deposits or any other surface contamination. Rinse the surface thoroughly with water, ensuring that a water break free surface is obtained.

Do not paint during cold or wet weather. Not to be used under nitrocellulose products. Allow a minimum of 72 hours dry/cure if solvent based paint is used.

Stir thoroughly with flat paddle before use. Ready for use by brush, roller or airless spray. Thinning not normally necessary. Clean up with water.
