Ask five painters in Bali to repaint a metal fence and four will arrive with one tin of enamel and no primer. That single-coat habit is why most metal here gets repainted every year. A protective coating is a system, not a colour: a zinc-rich primer that bonds to steel and fights corrosion sacrificially, a high-build intermediate coat that gives the film its thickness, and a UV-stable topcoat that takes the sun and the cleaning. Applied correctly, that stack lasts 4–6 years inland — and we have eight years of repaint records across the island to prove it.
What Goes Into a Three-Layer System
Zinc-Phosphate Primer
The corrosion protection layer. Applied to cleaned bare metal at 40–60 microns; zinc keeps protecting even when the film gets chipped.
High-Build Intermediate
The thickness layer — 60–80 microns of build coat that levels grinding marks and gives the system its barrier mass.
UV-Stable Topcoat
Polyurethane or premium alkyd finish in any RAL colour, gloss to matt. This is the layer Bali's sun attacks, so we never economise on it.
Application to Suit the Site
Spray for large even surfaces, brush and roller where overspray would land on cars, pools or plants. Same film build either way.
Why Three Layers and Not One Thick One
Each layer has a different job, and no single product does all three. Primer adheres and protects; topcoat resists UV and rain but sticks poorly to bare steel; build coat bonds the two and adds thickness. Skip the primer and the system peels; skip the topcoat and the epoxy or alkyd chalks to powder within a year of Bali sun. Total dry film of 120–160 microns is our standard — most one-coat repaints here measure under 40. For coastal properties we step up to the 250+ micron marine-grade specification.
Preparation is half of every coating job, which is why our quotes always include proper rust removal rather than listing it as an optional extra. And if you are weighing liquid coating against powder coating for a new fabrication, our comparison of powder coating vs paint in Bali walks through cost and durability honestly.
How It Works
Photos and measurements
Send photos and rough dimensions on WhatsApp. We reply with a per-m² or per-item quote the same day.
Surface preparation
Degreasing, rust removal and sanding for adhesion. Existing sound coatings are scuffed and feathered, failed ones stripped.
Three coats, correct intervals
Primer, build coat and finish applied within proper overcoat windows — rushing recoats is a classic cause of early failure.
Film check and guarantee
We measure dry film thickness on completion and back the system with a written 12-month guarantee.
What It Costs
Protective coating runs IDR 120,000–200,000 per m² including preparation, primer and two coats. Small fabricated items are priced individually — a garden bench from IDR 400,000, a window grille from IDR 250,000. Marine-grade upgrades add 30–40%. Full tables on the pricing page.
