Description

Raptor Acid Etch Primer Aerosol 450ml Grey is a 1K etch primer formulated to promote paint adhesion on difficult metal surfaces. Its phosphoric acid-based formula etches and primes bare metal in one step, while creating a protective barrier to help prevent steel corrosion. The flat-fan spray nozzle provides even application and broad coverage.

What Raptor Acid Etch Primer Aerosol is for

This primer is designed for preparing bare metal panels and repairing areas where the existing primer has been rubbed through. It is particularly suitable for aluminium and galvanised steel, helping create a surface that is ready for compatible paint systems. It can be overcoated directly under suitable conditions without sanding.

For surfaces that need additional adhesion promotion rather than acid etching, Raptor Adhesion Promoter Aerosol 450ml Clear is designed for suitable automotive substrates, including plastics, aluminium and galvanised metal. For added corrosion protection and a primer layer beneath a compatible protective coating, consider Raptor Anti-Corrosive Epoxy Primer 1.5L Kit Grey.

How to apply the Raptor Acid Etch Primer Aerosol

1. Ensure the surface is clean, dry and free from grease, dirt and loose corrosion.
2. Shake the aerosol thoroughly before use.
3. Spray evenly over the prepared bare metal, keeping the can moving to achieve a uniform coat.
4. Allow the primer to dry according to the product’s application conditions.
5. Overcoat with a compatible water-based or solvent-based basecoat or solid colour. Under normal conditions, sanding before overcoating is not required.
6. If additional filling or film build is needed, apply a suitable primer filler before the topcoat.
