At a glance
What does factory and industrial painting actually cover?
The coated surfaces of a working plant: structural steel and PEB frames, shed walls and soffits, pipework and machinery, floors and bay markings. The specification is set substrate by substrate, because cleaned steel, galvanised sheet and plastered masonry each need different preparation and primer. Work runs to a written method statement, inside your shift or shutdown window.
When this is the answer, and when it is not.
Sending you to the wrong service wastes your money and our time. This is how to tell.
This is likely right if
- Shed walls, structural steel and soffits have gone chalky, patchy or grimy, and the plant wants one consistent finish again
- Rust is showing at connections, base plates and purlin cleats, and you want it taken back and re-coated before it eats into the section
- A new PEB shed or extension is being handed over and the shop coat on the steel needs completing on site
- A customer or client audit is due and safety colour coding, bay markings and clean wall lines have to be reinstated
Something else comes first if
- Steel has corroded through, deep pitting, flaking layers or lost section at base plates and purlins. That needs a structural engineer's assessment and fabrication repair first; a coating over a wasted member only hides it
- Roof sheets or wall cladding are leaking at laps and fixings. Water tracking behind the film lifts it off the substrate, so sheeting, laps and gutters are sealed before anything is coated
- The floor slab is pushing moisture up, or oil has soaked deep into the concrete. A floor coating over either will delaminate, so a moisture test and a grinding and degreasing regime come first
What the service includes.
Substrate survey and coating specification
We walk the plant with your maintenance team and record what each surface actually is, PEB steel, galvanised cladding, plastered block, concrete floor, pipework, with its rust grade, its oil contamination and how well the existing coating is still holding.
Method statement and permit coordination
A written sequence for each area: access method, preparation method, coating system and coat count, with height, hot work and confined space permits raised through your safety team before anyone starts.
Containment and protection of plant
Machinery, control panels, cable trays, conveyors and stock sheeted and taped, the working bay barricaded, and overspray and dust kept inside that bay rather than travelling down the shed.
Degreasing and mechanical preparation
Oil and process grease washed off first, because no coating bonds through it. Then loose rust, mill scale and flaking paint taken back by wire brush, needle gun or power disc, and sound old coating abraded and feathered.
Primer matched to the substrate
Anti-corrosive primer on cleaned steel, a zinc-tolerant system on galvanising, alkali-resistant primer on fresh plaster and concrete. One primer used across a mixed plant is how coatings end up failing in patches.
Application and film thickness records
Brush, roller or spray chosen per area and per constraint, with wet film readings taken during the coat and dry film readings on steel afterwards, recorded area by area and handed over with the work.
Not included, or quoted separately
- Structural steel repair, welding, and replacement of members that have lost metal, a fabricator's and a structural engineer's work
- Electrical isolation, lock-out and permit issue, which stays with your own plant team; we work to it, we don't hold it
- Roof sheet replacement, lap and fixing sealing, and gutter repair, quoted separately, and completed before coating wherever there's a leak
- Disturbing or removing asbestos cement sheeting and pipe lagging, specialist removal work with its own containment and disposal, and not a painting crew's to touch
- Machinery dismantling, cleaning of process residue, and removal of production waste from the working bay
The sequence.
Site walk and substrate survey
With your maintenance and safety people. We note every substrate and its condition, the live services overhead, what can be stopped and what can't, and where access equipment can physically stand.
Specification and quotation
A coating system written against each substrate, preparation standard, primer, coats and film build, with the area schedule it is measured from. This is what the quotation is built on.
Method statement, permits and induction
The method statement and risk assessment go to your safety team, our crew take your site induction, and isolation points, permit route and the shift or shutdown windows are fixed before mobilisation.
Containment and access
Bay barricaded, plant and stock sheeted, extraction and ventilation agreed, and access set up, mobile tower, scaffold or boom lift with harness points confirmed for work at the rafters and crane girders.
Preparation and priming
Degrease, mechanical clean back to sound metal or sound coating, then prime the cleaned steel before it flash rusts. Bare steel left standing in Bengaluru humidity blooms again, and priming over that bloom is priming over nothing.
Coat, check and hand the bay back
Coats applied to the stated build, film thickness checked and recorded, sheeting and barricades cleared, the bay swept, then walked with your engineer along with the coating schedule and a written warranty setting out its conditions.
What moves the price on this job.
We do not publish a rate, because it would change once someone measured your property. These are the variables that decide it.
- Measured coating area by substrate, developed area of the steelwork, wall and soffit area, floor area, not the plant's built-up figure
- The rust grade of the steel and how much scale and flaking coating has to come off before a primer can go on, which is the largest variable in the work
- Whether we work live in shift gaps, at night, or inside a shutdown, and how many times a bay has to be handed back part-finished
- Access to rafters, crane girders and high-level services, mobile tower, scaffold or boom lift, and whether it can be positioned over live plant at all
- The exposure the coating has to survive: a dry storage bay, a wash-down area, chemical splash zones and hot surfaces each call for a different system
- How much masking and containment the plant demands, exposed product, sensitive panels and running conveyors all add protection work before any painting starts
Factory and Industrial Painting — your questions.
Can you work while the plant is running?
Often yes, bay by bay. We agree which areas can be barricaded off, work to your permit system, and hand each bay back cleaned before the next one opens. Some work can't be done live, spraying near air intakes, coating over running conveyors, anything with a fume or spark risk beside solvent storage. That work goes into a night or shutdown window, and we tell you at the survey which is which.
How do you deal with rusted structural steel?
We take rust back mechanically, wire brushing, needle gun, power disc, until what's left is sound metal and firmly adherent old coating, then feather the edges and prime the cleaned steel before it flash rusts. Bare steel left standing overnight in humid weather blooms again, and priming over that bloom is priming over nothing. Where a member has pitted deeply or lost metal, that's a structural and fabrication matter, and we say so rather than coat over it.
Will you paint galvanised cladding and sheeting?
Yes, but not with an ordinary metal primer. Fresh zinc is smooth and chemically active; several common primers react with it and the film peels away in sheets a season later. Galvanised surfaces are washed to remove white rust, dust and site grime, abraded to give a key, and primed with a system meant for zinc. Weathered galvanising behaves differently from new, so we test adhesion on a patch before committing a whole elevation.
How do we know the coating went on at the thickness specified?
Wet film thickness is checked with a comb gauge while the coat is still wet and can be corrected, and dry film readings are taken on steel once it has cured. Those readings are recorded area by area on a sheet you keep, along with what was applied where. That record is what lets your maintenance team match a touch-up coat later instead of guessing, and it is what each area sign-off is based on.
What about odour, fumes and dust near production?
Solvent-based systems have odour and need ventilation, so where the plant is occupied or product is exposed we specify water-based systems and apply by roller and brush rather than spray. Where spray is the only sensible method on structural steel, the bay is sheeted, the work is placed in a shutdown window, and the air path is confirmed with your engineer first. Dust is the other risk: it settles into a wet film and stays there, so preparation and coating are separated rather than run side by side.
