Products for painting steel or aluminium boat hardware

Steel and aluminium boat hardware above the waterline needs a clean, keyed surface, a suitable primer stage and a durable finish that can handle handling, weather and occasional water contact.

What do you need to paint steel or aluminium boat hardware?

Cleaning and degreasing

Mipa silicone remover in liquid or spray format removes oil, wax and handling residue from brackets, covers, handles and fittings before coating work begins.

Epoxy primer stage

Mipa EP primer filler with EP Hardener E 25 normal and EP Thinner gives prepared metal hardware a stable epoxy base before the colour coat.

Satin gloss 2K PU topcoat

Mipa PU 250-70 in the matching price group gives a satin gloss polyurethane colour finish for prepared steel or aluminium parts, used with PU 912-25 hardener.

Aerosol coating option

Mipa DS 4 in 1 Spray is useful for small hardware where a high-build acrylic aerosol with corrosion protection, primer and topcoat function is the most practical method.

2K thinner

Mipa 2K Thinner Normal V 25 adjusts compatible 2K coatings to the intended working viscosity when the chosen system calls for standard thinner.

How to paint steel or aluminium boat hardware

1
Remove and clean parts

Take off loose fittings where possible, wash away salt and dirt, then dry thoroughly before surface preparation.
2
Sand to a firm key

Abrade old paint and bare metal until the surface is solid, dull and free from oxidation, loose corrosion or glossy patches.
3
Degrease before coating

Use Mipa silicone remover after sanding so fingerprints, wax and dust do not sit under the primer or topcoat.
4
Prime and finish

Use the epoxy primer stage for bare metal hardware, then finish with Mipa PU 250-70 or use Mipa DS 4 in 1 Spray for small aerosol jobs.
5
Refit carefully

Allow the coating to cure before tightening fasteners, reinstalling covers or exposing the parts to weather and handling.

Which hardware coating method fits the part?

Use 2K PU for the strongest finish

Choose Mipa PU 250-70 with PU 912-25 for prepared metal hardware when a durable satin gloss colour coat is preferred.

Use DS 4 in 1 for small parts

Choose Mipa DS 4 in 1 Spray for small brackets and covers where aerosol application is faster and easier than mixing a liquid 2K system.

Use epoxy primer on exposed metal

Prepared aluminium or steel benefits from the epoxy primer stage before a separate colour coat, especially on edges and drilled fixing points.

Technical details

Mipa PU 250-70 is a 2K polyurethane topcoat in satin gloss for prepared metal parts, structures and facade type elements.
Mipa DS 4 in 1 Spray is a fast drying high-build acrylic single-layer aerosol with corrosion protection, primer and topcoat functions.
Aluminium must be abraded and cleaned carefully because smooth oxidised aluminium gives paint less mechanical grip.
Avoid coating parts that remain constantly underwater unless the complete marine coating method has been checked for that exposure.

Practical suggestion

For mixed steel and aluminium hardware, sort the parts first. Small brackets can be sprayed separately, while larger or more exposed parts usually deserve the epoxy primer and 2K PU method.
