BaliAntiCorrosion started in 2017 with a simple observation: every gate, railing and roof truss on this island was being painted by general handymen with one tin of enamel and no primer — and being repainted again twelve months later. We came at it from the other direction, borrowing the materials and discipline of marine and industrial coating: proper surface preparation, zinc-rich primers, measured film thickness, and systems specified to the actual exposure of the site. Nine seasons later, that approach has gone onto metal on hundreds of properties spread across the southern coastline and inland toward Ubud.
How a Job Actually Runs
We diagnose from a photo before we ever drive out. Send pictures over WhatsApp and you'll have an estimate the same day, including an honest steer toward DIY or even away from restoring it at all — our own DIY guide exists because plenty of rust spots genuinely don't need a professional.
The paint is the easy part. Grinding, sanding, rust-converting and priming eat up most of every job — unglamorous work nobody photographs, and the actual reason a coating from us holds for 3–6 years while a bucket-and-brush repaint fails within one.
No single coating fits every address. A gate sitting inland in Denpasar and a railing on a Uluwatu cliff face are fighting completely different conditions, so we spec the system to distance from the sea, wind exposure and the base metal — that reasoning is spelled out on each service page.
What we quote is what we invoice. Should a section turn out worse underneath than the surface suggested, work stops there and then — you get photos and a revised number to approve before anyone continues.
Our Guarantee, Spelled Out
Every job leaves with a written 12-month promise behind it: peeling, blistering or returning rust on a section we treated inside that year gets redone at no cost, materials included. Beachfront jobs aren't excluded from this — they're most of our workload, which is exactly why we push marine-grade systems where ordinary paint would fail early anyway. What it doesn't cover is new damage (a scooter clipping the gate) or any section you specifically told us to skip against our recommendation, which we always confirm in writing once the job wraps up.
What's Actually in the Tin
Bare steel gets zinc-phosphate or zinc-rich primer, full stop. Coastal jobs move up to high-solids epoxy barrier coats with an aliphatic polyurethane topcoat; inland work runs on premium alkyd or polyurethane enamel; pitted surfaces get a phosphoric-acid converter before anything else touches them. Every tin comes from marine or industrial suppliers rather than a hardware-store paint aisle, and we'll show you the actual labels on site — hiding what's going onto your steel isn't something an honest contractor does.
Where the Crew Works, Day to Day
Denpasar, Sanur, Jimbaran, Nusa Dua, Uluwatu, Kuta, Seminyak, Berawa, Canggu and Ubud — ten districts, one price sheet, 08:00 to 20:00 every day of the year. Full numbers live on the pricing page.
