Substrates

• HMG SPS Primer Finish is suitable as a primer/finish coat for suitably prepared metals, clean and free of grease, oils and other contaminants
• Not suitable for coating over bitumen or chlorinated rubber coatings

Application Climate

• Substrate temperature should be 5⁰C or above for application and during cure, and a minimum of 3⁰C above the dew point
• Adequate dry air ventilation should be supplied during drying

Application Information

• Thinning should only take place after material is thoroughly mixed
• Application and use should always conform with the codes of practice described in BS 6150 and BS 5493

Surface Preparation

• Ensure surfaces are clean, dry and free from grease, oils, dust and other contamination prior to application
• Thoroughly clean and degrease using suitable HMG Prep Clean 2802, HMG 2803 or HMG 2804
• Rust/corrosion to be removed to Sa or St standards, remove to clean metallic appearance with little or no rust/corrosion present
• Areas where blast cleaning is not cost effective or practical, then the use of HMG Ferrozinc is an alternative
• Though Ferrozinc is not an equivalent alternative to shot blasting, it does offer a far superior performance than conventional coatings applied to slightly rusted surfaces
• Read and follow safety data sheet, technical data sheet (see section above) and label instructions
• Stir paint thoroughly before use
• Always use the same batch number on the same job
• Filter the product immediately before use
• Reduce emissions and maintain quality by replacing tin lid after use

Bare substrates

• Mild steel – Remove millscale and thoroughly degrease using suitable HMG Prep Clean. Abrade with P80 – P180 if necessary, prior to application of primer
• Shot Blasted Steel – Remove all traces of blast grit/sand prior to application of primer
• Aluminium – Abrade with P180 – P320, degrease with suitable HMG Prep Clean prior to application of primer
• Galvanised Steel – Degrease with suitable HMG Prep Clean, apply HMG Mordant Wash, apply HMG Etch Primer and if required use appropriate HMG Primer

Previously Painted

• High pressure wash to remove all loose debris and poorly adhered previous coatings to remove all salts and other contaminants
• Degrease using suitable HMG Degreaser 2800 to remove grease and oils not removed with pressure washing alone
• Existing coatings to be well adhered with all edges tight and well feathered. Rust/corrosion to be removed back to clean metallic appearance
• Abrade to provide good adhesion
• Wipe over with degreaser to remove loose debris from abrasion
• Substrate to be clean, free of grease, oils, dust and completely dry prior to application
