Paint balcony railings and exterior handrails

Guided metal coating

Guide to painting balcony railings and exterior handrails

Balcony railings and exterior handrails need a coating build that grips the metal, resists weather and leaves a clean semi gloss finish on bars, joints and hand contact areas.

What do you need to paint balcony railings and exterior handrails?

Cleaning and degreasing

Mipa silicone remover in liquid or spray format removes grease, wax and silicone before sanding, primer or topcoat work starts.

Sanding and surface keying

MP Sanding Sponge helps dull old paint and smooth small edges so primer and finishing coats can grip the metal surface more evenly.

Epoxy primer for exposed metal

Mipa EP 100-20 with Mipa EP 950-25 hardener and Mipa EP Thinner gives the metal a 2K epoxy primer stage before the decorative finish.

Spray primer for small areas

Mipa 1K Epoxy Primer Spray is useful for smaller rubbed through areas, corners and local repairs where a spray can is the practical primer format.

Semi gloss polyurethane finish

Mipa PU 250-50 in price groups I, II and III creates the semi gloss colour finish, used with Mipa PUR Plus Hardener A60 net and Mipa 2K Thinner Normal V 25.

How to paint balcony railings and exterior handrails

1
Clean the metal

Remove dirt first, then degrease the railings and handrails with Mipa silicone remover so sanding dust and grease do not stay under the coating.
2
Sand and remove weak coating

Key sound paint, feather damaged edges and remove loose rust or peeling coating until the remaining surface is firm.
3
Prime bare or repaired areas

Use the specified primer stage on exposed metal and let it dry according to the technical information before the next layer.
4
Apply the colour coat

Apply the semi gloss polyurethane colour in controlled coats, keeping edges, welds, corners and underside returns covered.
5
Let the finish cure

Allow the coating to harden before assembly, handling or outdoor exposure, especially on parts that will be touched or cleaned often.

Which railing coating products should you choose?

Use the 2K system for exposed railings

Choose Mipa EP 100-20 under Mipa PU 250-50 when the railing is outdoors and needs a stronger primer and colour build.

Use spray primer only for local areas

Mipa 1K Epoxy Primer Spray is best kept for small bare spots, joints and repaired details rather than large railing runs.

Choose the colour group carefully

Mipa PU 250-50 price groups I, II and III let the final colour match the required railing finish while keeping the same coating role.

Technical details

Mipa PU 250-50 is the main semi gloss 2K PU finish for balcony railings and exterior handrails; it is matched with Mipa PUR Plus Hardener A60 net and Mipa 2K Thinner Normal V 25.
Mipa EP 100-20 is the 2K epoxy primer stage for steel, zinced steel, aluminium and GRP when the substrate and preparation match the technical data.
Mipa EP 100-20 must be used with Mipa EP 950-25 hardener and Mipa EP Thinner, not with the PU topcoat hardener.
Mipa 1K Epoxy Primer Spray is a local spray primer option for smaller areas, edges and spot repairs.
Clean first, sand second and degrease again before coating so hidden grease is not trapped under the primer or finish.

Practical suggestion

Remove loose rust thoroughly from welds, corners and underside areas before primer. These are the areas where outdoor railings usually fail first.
