Guide to painting a new steel gate or railing

A new steel gate or railing needs degreasing, keying, corrosion resistant primer and a durable semi gloss topcoat before it is exposed outdoors. This guide uses Mipa EP 100-20, Mipa PU 250-50 and the matching components for a complete steel coating method.

What do you need to paint a new steel gate or railing?

Cleaning and degreasing

Mipa silicone remover in liquid format or Mipa silicone remover spray removes grease, dirt and handling residue before sanding, priming or topcoating.

Surface keying

MP Sanding Sponge prepares corners, bars and detailed metal surfaces so the next coating layer has a clean mechanical profile.

Epoxy primer for steel

Mipa EP 100-20 with Mipa EP 950-25 hardener and Mipa EP Thinner creates the corrosion resistant primer stage for steel gates and railings.

Aerosol primer for detail areas

Mipa 1K Epoxy Primer Spray supports small repair areas, posts, welds and edges where aerosol application is more practical.

Semi gloss PU topcoat

Mipa PU 250-50 in the relevant price groups gives the fence or railing a durable semi gloss industrial finish in the chosen colour method.

Topcoat components

Mipa PUR Plus Hardener A60 and Mipa 2K Thinner Normal V 25 are used in the PU topcoat stage and help the final coating cure and apply correctly.

How to paint a new steel gate or railing

  1. 1
    Wash and degrease

    Clean the new steel gate or railing thoroughly so dirt, oils and surface contamination do not reduce adhesion.

  2. 2
    Remove loose material

    Key edges, welds and detailed areas so the primer stage can bond to a clean and stable surface.

  3. 3
    Prime the substrate

    Use the epoxy primer method matched to the metal type before the final semi gloss coating is applied.

  4. 4
    Apply the PU finish

    Apply Mipa PU 250-50 with the correct hardener and thinner so the final layer protects the prepared metal and gives an even semi gloss look.

  5. 5
    Respect drying before service

    Let the new steel gate or railing cure before frequent touching, gate movement, cleaning or weather exposure becomes heavy.

Which steel gate coating method should you choose?

Full steel coating method

Choose EP 100-20 primer and PU 250-50 topcoat for a complete system on new or bare steel gate and railing work.

Aerosol primer for small details

Choose 1K Epoxy Primer Spray for compact details, small edges and isolated prepared spots before the topcoat.

Brush or roller friendly finish

PU 250-50 is suited to metal constructions where controlled brush or roller application is useful on bars and railings.
