A useful epoxy coating quotation starts with a clear description of the work, rather than a product name and an approximate number of kilograms. The substrate, its existing condition, the operating exposure and the preparation that can actually be achieved all belong in the same enquiry. Without that information, two prices may appear comparable while covering different requirements. One supplier may include only the finish, another may include a primer and ancillary materials, and the quantity may refer either to the complete two-component pack or to the base component alone. Preparing the information before requesting a price makes these differences visible.
This guide sets out an epoxy-specific enquiry approach for technical buyers, maintenance teams and application contractors. Before choosing an epoxy topcoat, define the boundaries of the work. Products within the same resin family should not be assumed suitable for every substrate, chemical or operating condition. A well-prepared enquiry identifies the basis for selection, the questions that still need an answer and the requested pack quantities. The commercial discussion can then proceed with an explicit technical scope instead of assumptions that may change after an order has been placed.
1. Establish the project scope on a single opening page
Start with the project name, the facility or component group, whether the work concerns new fabrication or maintenance, and the person responsible for the technical decision. A description such as “protection of metal surfaces” is too broad to support a reliable assessment. Structural steel, machinery housings, equipment in storage areas and concrete floors can present different coating requirements. Identify the included components, the surfaces that must remain uncoated and whether application will take place in a workshop or on site. These boundaries influence material evaluation as well as quantity and delivery planning.
Separate material supply from application services. If the enquiry concerns paint alone, it should not imply that abrasive blasting, labour, access equipment or scaffolding are included. Where an applicator has already been appointed, provide relevant contact and equipment information. If that appointment is still outstanding, say so. When reviewing industrial coating solutions, make the requested supplier contribution clear: identify products against an existing specification, assess a possible system alternative, or highlight missing project information. These are different assignments and may require different supporting evidence. Clear responsibilities at this stage prevent a provisional product suggestion being mistaken for approval of the complete works.
2. Distinguish the substrate, existing coating and local variations
Do not combine steel, galvanised surfaces, aluminium, concrete and previously coated substrates into one undifferentiated area figure. Where several materials occur within the same structure, identify them by location or component reference. New steel may require consideration of fabrication contamination and weld areas, while maintenance work also involves corrosion, the condition of existing layers and difficult access. For concrete, “looks dry” is not an adequate description: record its known age, existing coating, the available moisture assessment and the intended service. These details are starting information for a technical review, rather than an unsupported diagnosis.
If the existing coating is known, record the product code and application history. If it is unknown, keep a suspected coating family clearly separate from confirmed information. Include overview and close-up photographs showing detachment, rust and contamination. The need for an epoxy primer does not follow automatically from the name of the finish; it depends on the substrate and preparation conditions as well. Whether an apparently sound old film can receive a new coating should not be decided from a photograph alone. Any required investigation or compatibility trial belongs in the enquiry as an open technical item, with an identified decision owner.
3. Describe exposure through operating information
Expressions such as “heavy-duty service”, “chemical resistant” or “marine environment” do not provide enough information on their own. Record indoor or outdoor location, exposure to sunlight, the form of water contact, cleaning practices, temperature changes and mechanical wear separately. Where chemicals are involved, request the substance identity, known concentration, temperature and whether contact is occasional splashing or continuous exposure. If the operating information is unavailable, request confirmation rather than hiding the uncertainty. Continuous immersion, food contact and potable-water use require documented suitability for the exact product and system.
ISO 12944-2 addresses the classification of environments relevant to protective paint systems for steel structures. It provides context for recording exposure; it does not automatically certify a supplier or establish the suitability of a particular product. Where a project specifies a category, attach its basis and the applicable specification revision. Using a shared coatings glossary helps the parties distinguish terms such as drying, curing, coating system and exposure. If a classification is unknown, agree who will assess it instead of expecting a supplier to guess. The enquiry should distinguish measured conditions, client requirements and items awaiting technical confirmation.
4. Define surface preparation that can realistically be achieved
An ideal preparation method written into a quotation is not evidence that it can be carried out on site. Access, working hours, dust control, nearby sensitive equipment and the available shutdown period may restrict the work. Identify the feasible method, available equipment, isolation period and inspection responsibility. If the project specifies a cleanliness or profile requirement, communicate it accurately; do not invent a universal preparation grade for every product. Handling and waiting arrangements that prevent recontamination after preparation also form part of the work and should not disappear between the specification and the enquiry.
For components that received temporary workshop protection, request the earlier product code and information about compatibility with subsequent coats. An epoxy shop primer should not be assumed to perform the same role as the final system primer. Repairs following welding, cutting or assembly can be identified separately. Uncertainty caused by inadequate preparation cannot simply be resolved by ordering more paint. Marking areas as “subject to pre-application assessment” makes the conditions behind the quotation understandable and helps avoid unexpected changes after ordering. The enquiry should state what is known, what can be achieved and what requires further approval.
5. Assess the finish within the complete coating system
A request for an epoxy finish should not overlook the layers beneath it. List the existing or proposed primer, intermediate coat, finish and local repair products in their intended sequence. For each layer, request the product code, function, planned application method and any film thickness defined by the project. Where these details have not been established, retain a visible “to be confirmed” entry. This prevents missing layers being filled through unrecorded supplier assumptions and stops different quotations being treated as though they describe the same system.
Outdoor appearance and colour retention requirements may lead to an assessment of alternative finishes. Options such as a gloss polyurethane topcoat should not be recommended over an existing epoxy merely because of their resin-family description. The exact product, substrate, intercoat compatibility and intended application must be checked together. This guide does not prescribe one coating build-up for every project. Its purpose is to make the conditions and evidence behind a system decision explicit. Where a substitution is proposed, retain both the original requirement and the reason for the alternative so that the buyer can assess the change.
6. Separate area, theoretical consumption and purchase quantity
Link the coating area to drawings or an identified measurement source wherever possible. Component count, repeated geometries, elements coated on both sides, corners and restricted areas influence how the calculation is made. If the area is estimated, identify the limits of that estimate and the responsible party. A total mass stated before the area is established remains an initial planning figure. Showing each coat and its applicable area separately helps prevent the same surface being counted twice or omitted. Where the coating scope varies between components, use separate lines rather than forcing the variation into a single average.
A coverage figure in a technical document is meaningful alongside the stated film thickness and conditions. It is not automatically the order quantity: application losses, geometry, substrate condition and application method also require consideration. Consumption data for materials in the product range should be compared on a consistent basis. Do not treat kilograms and litres as interchangeable without confirmed density information. The quotation table should distinguish area, calculation basis, allowance assumptions and recommended purchase quantity. Retaining those assumptions makes it easier to understand whether a later quantity change results from revised area, a different system or a commercial pack-size adjustment.
7. Make complete-pack quantities and component scope explicit
For a two-component product, “one pail” does not establish whether the request refers to the base component or to the supplied base-and-hardener set. State the total pack mass, number of packs and, where required, the confirmed A/B breakdown. The website pack selector organises an enquiry; final availability and component information are confirmed before ordering. Do not transfer the component distribution of one epoxy product to every other two-component material. When a product code changes, check the pack contents again instead of carrying over a familiar ratio from an earlier purchase.
Small maintenance areas and extensive workshop application may benefit from different pack arrangements. Assess daily application capacity, work divisions and the relevant mixed-material working time alongside the unit cost of a larger pack. Show thinners and ancillary products as separate lines. During discussions about transport, pack count and staged deliveries, distinguish net material quantity from the transport unit. At the end of the quotation, each line should clearly represent a coating product, a complete set or an ancillary material. A simple pack reconciliation prevents the hardener being counted twice or excluded from a comparison of competing prices.
8. Assign different roles to hardener and thinner
The hardener is a specified component of a two-component system; thinner is an ancillary material used under the conditions applicable to the exact product and method. These items are not substitutes in a quantity schedule. Confirm the base and hardener codes together and identify the appropriate thinner separately. Selecting an epoxy thinner requires more information than the generic word “thinner”. A material used with another coating system is not established as compatible simply because its appearance or trade description seems similar.
When a mixing ratio is communicated, make its mass or volume basis and product reference visible. An archive catalogue value should not become a site instruction without confirmation against the current product and application conditions. If partial packs are proposed, the measurement and preparation method should follow the relevant manufacturer instructions; splitting a pack by eye is not an appropriate enquiry assumption. Stating equipment, method and daily work quantity together also supports realistic packaging decisions. The published guide to two-component paint, hardeners and thinners provides further explanation of these distinct roles.
9. Keep concrete-floor work separate from metal coating items
Steel equipment and concrete flooring may form part of the same factory maintenance programme, but they should remain separate items in the enquiry. Floor work requires its own description of traffic, cleaning practices, existing coating, joints, water contact and the commissioning programme. A finish selected for metal should not be assumed to meet every flooring requirement. First establish whether the intended work is thin-film painting, local correction or a different floor-coating system. The area alone cannot describe that difference, and it should not be concealed in a general request for epoxy paint.
Products such as self-levelling epoxy paint and a clear epoxy coating represent options with different functions, rather than interchangeable entries using the same quantity calculation. Where concrete assessment and scope definition are necessary, state them as prerequisites. Tie the proposed programme, material quantity and product recommendation to those findings. The project team can also consult the published epoxy-floor guide covering moisture, loads and commissioning when completing the enquiry. Keep any unresolved substrate issue visible until a responsible technical decision has been made.
10. Specify colour, appearance and acceptance expectations
Where a colour code is supplied, identify the reference system and the substrate on which a sample will be assessed. The same nominal colour may be perceived differently with a different sheen or surface texture. For appearance-sensitive components, an approved sample provides a clearer reference than a verbal description. The enquiry can distinguish sheen expectations, visible surfaces and agreed assessment conditions. A photograph or screen image should not become the sole colour acceptance criterion. If several parties will approve the finish, identify the reference sample they will all use.
When specifying RAL colours, explain how the requirement will be verified as well as providing the code. Film thickness, appearance and other necessary checks should follow the project scope. ISO 19840 addresses dry-film thickness verification on rough surfaces; it should not be used to invent one universal reading count or acceptance value for every job. Define who inspects, how results are recorded and who can decide on a deviation. These arrangements allow the quotation to support an accountable coating project instead of remaining a list of products and quantities.
11. Manage the application programme and unanswered questions together
Delivery, application start and return to service are separate events. Material arriving on site does not establish that preparation can begin immediately or that application can be completed the same day. Weather, ventilation arrangements, access and coordination with other work affect the programme. Touch dryness, handling suitability and full service release are also different criteria. Numeric times should be assessed from the relevant product information in relation to actual conditions. A buyer should therefore request the programme basis, rather than treating a catalogue drying value as a guaranteed shutdown period.
Maintain a separate open-items list. For each question, identify the information owner, expected answer date and effect on the quotation. An unknown old coating, an unconfirmed area and an undefined chemical exposure are different uncertainties and deserve different priorities. Where detachment exists, the published epoxy adhesion-loss investigation guide can help the team record the affected areas. That investigation should not be reduced to a decision to cover the defect with fresh paint. A firm system or quantity decision requires the relevant preparation and repair scope to be established.
12. Complete the quotation basket alongside the technical file
Adding products with their pack choices and quantities to the website quotation basket provides a practical way to organise a request. It is an enquiry workflow, not an online purchase or payment transaction. Include colour, project notes and the intended area so that the first technical discussion can address the relevant issues promptly. Where the same product will serve different locations or delivery stages, make that distinction clear in the notes. A well-organised basket supports the project file, but it does not replace information about the substrate, exposure or specification.
Before sending, check product codes, complete-pack quantities, ancillary materials and contact details. If a specification, survey summary or photographs are available, identify the file name and revision. Commercial terms, final availability and application suitability are clarified during assessment. When contacting Versan Boya for technical assistance, the most useful file is not the largest collection of unrelated documents. It is a readable record of the decision basis from substrate to packaging. This preparation makes quotation scope easier to compare and helps the buyer ask the right questions before committing to an order.
13. Read the file from another team member's perspective
Ask someone outside the immediate preparation team to review the enquiry before submission. Can they identify what will be coated, how many complete packs are requested and which technical points remain open? Conflicting units or inconsistent product codes often become visible in this review. If photographs cannot be matched to locations, rename them with useful references. Where an earlier specification and a current request share a folder, state which version governs the enquiry. These small checks improve clarity without increasing the technical scope or creating unnecessary administrative work.
Once responses arrive, retain the original enquiry unchanged and keep dated questions and answers in an accompanying record. If a supplier proposes a different product or quantity, record the reason in the same decision trail. Purchasing, maintenance and application teams can then work from a common version rather than separate email interpretations. The purpose is traceability, not document volume. Assigning an owner and answer date to an unresolved technical item is more useful than silently accepting the uncertainty. Place the final order only after the relevant technical and commercial conditions have been agreed.
Sources and document scope
Product descriptions were checked against the technical catalogue documents available on the website. An archive document does not replace confirmation of the current product code, revision or project-specific suitability. This article does not prescribe a universal mixing ratio, film thickness, service-life guarantee or resistance to all chemicals. It provides a method for preparing information that supports a technical quotation assessment.
