Develop a workable steelwork coating specification covering exposure, preparation, edges, welds and primer–finish compatibility.
Describe exposure rather than location alone
“Inside a factory” is not a complete exposure description. Condensation, process vapour, chemical splashes and washdown may vary across the structure. Assess columns, platforms and external projections separately, including future maintenance access in the coating decision.
Connect fabrication details with coating preparation
Sharp edges, weld spatter and water traps can complicate application. Review these details before the coating team arrives. Preparation grade, surface profile and cleanliness acceptance are separate specification items; simply writing “blast clean” does not define all inspection requirements.
Approve the system by exact product code
An epoxy primer and polyurethane finish may be considered, but generic names do not complete approval. Verify the exact products, recoating requirements, preparation and specified thickness against project conditions. Site touch-ups also need a procedure compatible with the shop-applied system.
Technical framework: from substrate to system
An industrial coating specification must connect service exposure with the capabilities of the production line. Steel, galvanised steel, aluminium and previously coated surfaces cannot automatically share the same preparation procedure. Choosing by resin name alone is incomplete without identifying whether the component will operate outdoors, face chemical splashes or remain in a dry interior. Chemical identity, concentration, temperature and duration of contact all matter.
Define the system as primer, any required intermediate coat, finish and approved thinner. Similar product names are not evidence of intercoat compatibility. A sample prepared or applied differently from production may not represent the finished component. Technical approval should ensure that purchasing, application and inspection teams use the same product codes and document revisions.
Start this assessment with the Industrial Coatings range and refer to the coatings glossary for terminology.
Example project scenario
Consider a steel platform destined for an outdoor site. Plan for bolts, field welds and transport damage as well as flat shop-coated surfaces. Include product codes, inspection records and a repair procedure in the handover file. Prioritise areas that become inaccessible after assembly, turning coating selection into a decision covering installation and maintenance rather than initial application price alone.
Checks before making the decision
- Exposure: map condensation, sunlight and chemical-contact zones.
- Preparation: specify cleanliness, profile and edge treatment separately.
- Inspection: include difficult areas in the measurement plan.
- Maintenance: agree site repairs and future access in advance.
Relevant products and system components
These records support comparison and technical discussion. Listing them together does not constitute an approved application system for every condition. Follow the links for packaging, technical scope and product-specific questions.
Nanomix Epoxy Primer
Epoxy Primer is a professional primer that promotes more uniform topcoat adhesion and provides a controlled foundation for the coating system.
Application scope: Prepared metal, light metal or other suitable industrial surfaces.
Nanomix Gloss Polyurethane Topcoat
Gloss Polyurethane Topcoat is a Nanomix coating solution developed to combine protection, an attractive finish and professional application performance on selected surfaces.
Application scope: Metal, wood, mineral or industrial surfaces specified in the product technical description.
Nanomix Epoxy Shop Primer
Epoxy Shop Primer is a professional primer that promotes more uniform topcoat adhesion and provides a controlled foundation for the coating system.
Application scope: Prepared metal, light metal or other suitable industrial surfaces.
Nanomix Polyurethane Thinner
Polyurethane Thinner is an auxiliary product developed to adjust the application viscosity of the corresponding coating system in a controlled manner and support professional application quality.
Application scope: Thinning the relevant Nanomix paint, primer or varnish systems; equipment cleaning where expressly specified as suitable.
Application, acceptance and maintenance planning
Do not restrict inspection to final appearance. Address preparation, cleanliness, application conditions, mixing records and wet and dry film checks at the appropriate stages. Instruments must suit the substrate and be checked before use; a single thickness reading cannot represent an entire component. Establish additional inspection points at edges, welds and inaccessible areas.
Touch dryness, handling strength and full chemical resistance are different release criteria. Tie dispatch, stacking and commissioning to the conditions in the current technical data sheet. Food contact, potable water, fire protection and continuous immersion require documented suitability for the exact product and system; they cannot be inferred from the coating family.
Preparing a technical enquiry and quotation request
Before contacting the technical team, prepare overall and close-up photographs. Identify substrate, any previous product, area or component count, colour and appearance requirements. State the application location, equipment and required completion date. Flag chemical contact, continuous immersion, food-related use or any other condition requiring specific documentation at the beginning of the enquiry.
Request separate identification of primers, finishes and auxiliaries alongside exact product codes. List unresolved technical values as items requiring written confirmation instead of filling them with assumptions. Keeping the approved sample, current technical data sheet and application records together allows purchasing and production to work from the same decision. Packaging information supports ordering, but product-page options do not represent live stock or a guaranteed delivery date.

Frequently asked questions
Is one thick coat sufficient?
It depends on the permitted coat thickness and approved system design. Extra thickness does not automatically improve protection and can cause drying or film defects. Do not reduce coat count arbitrarily for cost or speed.
Is a shop primer the final protective system?
Not necessarily. Confirm the shop primer’s purpose, overcoating compatibility and application limits. Subsequent fabrication or welding requires separate assessment; the presence of a primer does not establish a complete protective system.
