Flame-spread claims: check what the paint report covers

Identify the requirement behind the sales language

For a Saskatoon commercial interior, start with the finish specification or the owner's request that prompted the fire-performance discussion. Ask the responsible designer which requirement applies to each affected wall or ceiling. Keep an unexplained fire-rated paint description unresolved until the supplier identifies the exact claim. The purchasing team needs a defined requirement before it can evaluate a proposed upgrade.

UL Solutions' Canadian surface-burning overview explains that CAN/ULC-S102 reports flame-spread and smoke-development values for the particular product or assembly evaluated. This supports asking what was tested. It does not establish the applicable requirement for your building, approve a paint product or demonstrate the performance of an unexamined existing wall.

Keep the two fire-performance questions separate

UL 723's published scope describes comparative surface flame spread and smoke density under a test fire. It points separately to UL 263 for evaluating building constructions under fire exposure. These are different evidence questions. Do not convert a surface-burning result into an hourly wall rating or treat a US test reference as automatic acceptance for a Canadian project.

Have the designer identify the required test reference, relevant edition and review authority. Ask the supplier for the underlying report or applicable listing, including the specimen description and stated restrictions. If the proposal concerns existing intumescent protection on structural steel, route it into a separate specialist redecoration review; this article concerns evidence offered for an interior finish purchase.

Do not ask property staff to perform a flame demonstration or infer performance from a sample's appearance. A demonstration would not answer whether the supplied documentation applies to the proposed work. Keep testing and any code interpretation with the appropriate qualified parties.

Compare the tested specimen with the proposed wall

Give the reviewer a paired record: what the report describes and what the contractor proposes. Include the exact coating identity, substrate, underlying finish information, proposed layers and locations. Ask the reviewer which differences matter and what additional information is required. Mark unknown existing layers explicitly rather than silently treating an old painted wall as the report's new test panel.

In an illustrative office refurbishment, a supplier might submit evidence for a coating on one identified backing while the quotation includes several existing wall constructions. The next decision is which locations the evidence supports. Ask for clarification or a revised proposal for the remaining areas. Neither the coating's colour nor its use elsewhere establishes acceptance across the whole suite.

Request any actual cost and scheduling effects after the technical response. Keep an optional appearance change separate from work needed to satisfy the specified requirement. A lower price does not resolve an unanswered evidence question, and a higher price does not prove stronger protection.

Carry the reviewed limits into the purchase

Attach the accepted report reference, location schedule and reviewer's decision to the material approval. Return a changed product or substrate proposal for review before application. At handover, reconcile recorded materials and affected surfaces with that approval, leaving discrepancies visible until the responsible reviewer resolves them.

Bring the released decorative scope to a commercial interior painting discussion with PainterzRus and confirm the work offered. Specialist fire assessment, testing and certification require separate arrangements. This guide supplies no passing value, fire rating, product approval or claim that the business provides those specialist services.

Does a flame-spread result establish an hourly fire rating for the wall?

No. Keep the surface-burning claim within its tested scope. Ask the qualified project reviewer to identify the separate evidence needed for any claimed assembly fire resistance.
