Coating systems

Metal coating systems for Hampshire buildings

Painted metal fails from underneath. On Hampshire buildings — especially those catching salt-laden air — the answer is preparation grade first and product second.

Property managers and building owners with railings, gates, staircases, balustrade or plant screens showing rust breakthrough.

Direct-to-metal coating systems carried out by Dynamic Decorating across Hampshire

What the system is

Direct-to-metal systems combine a corrosion-inhibiting primer with a topcoat that tolerates movement and weather. Preparation grade sets the lifespan: wire-brushed rust bloom lasts a season, mechanically abraded and spot-primed steel lasts years. We describe systems generically and select from the manufacturer's data sheet for the substrate in front of us.

Preparation this system depends on

  • Rust graded by area and depth before any product is specified
  • Mechanical abrasion back to sound, keyed metal where breakthrough has started
  • Salt and contaminant wash-down on exposed coastal elevations
  • Corrosion-inhibiting primer applied within the same working day as preparation
  • Edges, welds and fixings stripe-coated before the full coat
  • Topcoat film build checked as work progresses

Where it is usually specified

  • External railings, gates and estate boundary metalwork
  • Fire escapes, external staircases and walkway balustrade
  • Plant screens, louvres and roof-level metalwork
  • Bollards, cycle stores and bin-store frames
  • Structural columns and exposed steelwork inside buildings
  • Metal doors, frames and roller shutter housings

Trade-offs worth knowing before you commit

  • Coastal exposure shortens the recoat interval — plan maintenance, not a one-off
  • Access equipment can cost more than the coating on high-level metalwork
  • Weather windows matter: cold, damp steel will not take a sound film
  • Galvanised and previously powder-coated surfaces need different primers
  • Heavily pitted metalwork may need fabrication repair before coating

Questions we get about metal coatings

Can you paint over existing rust in Hampshire?

Loose corrosion has to come off. We abrade back to sound metal, spot-prime the same day and then coat — painting straight over active rust simply hides it for a winter.

How long will a metal coating last around the Portsmouth and Southampton area?

It depends on exposure and preparation grade. Sheltered internal steelwork goes many years; exposed coastal railings need checking annually and recoating far sooner. We give a realistic interval, not a slogan.

Do you work on galvanised metal?

Yes, with a primer suited to galvanising. New galvanising in particular needs the right etch or adhesion primer or the topcoat will peel in sheets.

Is spraying or brushing better for railings?

Detailed railings around Hampshire are usually brushed for coverage into edges and joints; larger flat metalwork is often sprayed. Frequently we combine the two.

Can the work be done without closing access near Portsmouth?

Usually. We section the run, coat in phases and leave safe passage — the programme is written round access rather than the other way about.

Do you handle the access equipment?

Yes. Towers, MEWPs or scaffold are specified with the quote so the access cost is visible rather than a surprise on the invoice.

Send photographs of the metalwork at your Hampshire property and we will grade the corrosion before quoting.

Metal coating work in Hampshire lives or dies on preparation — we grade it, write it down and price it openly.
