Ensure that surfaces are sound and free from dust, oil, grease, dirt, and debris. Surfaces must be thoroughly dry – no more than 12% moisture content.

Rusted Metal Surfaces:

• Minimum standard for adequate performance – St 2 (Swedish Standard SIS 05 59 00).
• This should be achieved by abrasion with coarse emery paper, wire brush or needle gun/grinder, where applicable.
• All surfaces must be dry and free from loose rust, dirt, dust, grease and salt.
• Extremely rough or pitted ferrous metals will benefit from the application of Hammerite No. 1 Rust Beater before using Hammerite Direct To Rust Metal Paint.

Bare New Ferrous Metal Surfaces:
Degrease with Hammerite Brush Cleaner & Thinner

Painted Ferrous Metal Surfaces:

• Abrade the painted surface to remove contaminants/gloss.
•  Wash down thoroughly with Hammerite Brush Cleaner & Thinner, a proprietary metal  degreaser or diluted detergent both for removal of surface contaminants and soluble salts.
• Rinse with clean water and allow drying.
  N.B. Test for compatibility with existing paint by painting a small test panel area first. Any compatibility problems will be evident within the first hour after application. It there is a reaction remove all paint by most suitable means back to bare metal before apply Hammerite Direct to Rust Metal Paint directly to the ferrous metal.

Shiny, Smooth Metal Surfaces:

•  Extra abrasion is required to ensure maximum adhesion.
• Degrease with Hammerite Brush Cleaner & Thinner.

Unpainted/Bare Galvanised, Aluminium and Non Ferrous Metal Surfaces:

• Notes: In many areas, industrial and coastal districts in particular, soluble salts may contaminate the substrate. It is essential to scrub and rinse repeatedly with clean water to remove this contamination.
• To ensure maximum adhesion on aluminium and non-ferrous metal surfaces prime with Hammerite Special Metals Primer before applying Hammerite Direct to Rust Metal Paint.

• Brush: Suitable for small flat areas and intricate wrought ironwork. Do not thin. Apply 2 coats to achieve recommended dry film thickness. Allow minimum 4 hours between coats. Ensure that all edges and corners are adequately covered. Do not over-apply, as sagging will occur.
• Conventional Spray: Suitable for large, flat and uneven surfaces.
  N.B. The following products contain silicone, which affects the spraying of the product: Hammerite Hammered finish – all colours. Hammerite Smooth finish – gold, silver and copper.
  Thin with Hammerite Brush Cleaner & Thinner at a ratio of 15% thinner to paint. Set spray gun at 25/35psi approximately 2 Bar) and use full fan spray at maximum volume.
  Apply 4 thin coats allowing approximately 1 hour between coats. Do not leave too long between coats as this could lead to wrinkles forming. The final coat should be sprayed heavily enough to flow to a glossy finish avoiding runs and sags.
  Refer to spray equipment guidelines for the correct and safe use of sprayers. Shake spray gun before and during use to ensure an even colour.
• Airless Spray. If necessary thin with Hammerite Brush Cleaner & Thinner at a ratio of 15% thinner to paint. Fluid pressure: 2500 – 3000 psi (approximately 170 Bar). Nozzle size: 375-500 microns/0.015 – 0.020″. Apply 2-3 coats, leaving each coat for a minimum of 1 hour or until it is touch dry before applying further coats. Shake spray gun before and during use to ensure an even colour
• Aerosol. Suitable for touch-up/small applications. Store aerosol at room temperature for 2 hours prior to use.
  Shake can vigorously for a full 3 minutes AFTER the agitator ball is heard. Use a vertical rather than a horizontal motion.
  Apply light even coats from a distance of approx. 25-30cm.To avoid runs and sags keep the aerosol moving. Do not concentrate the spray in any one spot.
  Several thin coats are recommended, particularly on intricate and vertical surfaces. Allow approx. 15 minutes between coats.
  To avoid blockages, invert the can and spray for 2 seconds between coats and after final use.
