A method example makes the gap in “stain resistant” easy to see. Imagine an RFQ with two candidate lines: “matt, 0.3 mm wear layer” and “high gloss, 0.5 mm wear layer.” They are not a fair performance comparison until decor, core, backing and sample reference are also stated. The example is a purchasing exercise, not a Lanhe customer case.
What should stain resistance mean in an SPC flooring specification
In that exercise, the facilities note says that a colored drink is wiped with the site cleaner during the same shift. The record therefore needs the substance, approximate contact time, tool and drying point. If the project team cannot supply those details, the open item is the maintenance routine, not a missing stain adjective.
A second project could have a different note. A home may care about food; a hotel may care about repeated mopping; a shop with entry mats may ask about rubber contact. These conditions should not be blended into one score. Each belongs to the type of exposure the building is expected to create.
Which SPC layers affect the result
When the example sample dries, the reviewer writes two observations. “No residue at close view” describes removal. “A dull patch beside the control” describes appearance. A printed grain may make a trace harder to see, so distance and light belong on the sheet. The record is stronger when the reviewer reports what changed rather than choosing a single pass word.
Wear layer and surface treatment
The product line can use facts on Lanhe’s SPC page: wear-layer choices of 0.2, 0.3, 0.4 or 0.5 mm, or a buyer-specified value; B/P, matt, high-gloss, EIR, crystal and stone-grain finishes; total thickness options from 3.5 to 8 mm or customized; IXPE or EVA back foam; and Unilin or Valinge click systems. The page describes the wear layer as stain resistant, but does not publish a stain-test method for each combination. The supplier must identify which configuration the evidence covers.
Texture can change how a mark is seen
The method example uses the actual decor under the planned light. A dark oak print can hide a small trace that would stand out on pale stone. That observation concerns visibility, not removal. A close inspection and a normal viewing-distance inspection may both be useful, provided the sheet says which decision each one supports.
How to test samples before bulk ordering
The review sheet has an exposed plank and an untouched control. Before the liquid is applied, it records product code, finish, cleaner and contact time. After drying, the reviewer writes residue, sheen and texture in separate fields and attaches photographs. If another supplier uses a different cleaner or wait period, the two records answer different questions and should not be ranked as if they were one test.
Use representative exposures
The facilities note can include dilution and tool. Neutral detergent is a sensible starting point only when it is the normal site routine. A solvent or dye needs a project reason. Keeping the same procedure across samples matters more than adding a long chemical list that no one at the site will use.
Do not treat a visual wipe check as a certification
A hand wipe in this method example is a screen. Formal evidence has a different shape. ASTM F3261 covers modular resilient flooring with a rigid polymeric core, while ISO 26987:2008 specifies a procedure for staining and chemical response in resilient floor coverings. If the tender names one, the lab or supplier should confirm scope, specimen build-up and reporting for the quoted construction. A standard title is not a product result.
What to request in the RFQ and pre-shipment check
RFQ line: product code, decor, finish, wear-layer value, core, backing, total thickness and click system.
Sample note: physical reference, format, finish, lighting condition and date.
Review note: substance, contact time, tool, drying point, acceptance wording and formal method if required.
Receipt note: carton or production lot tied to the sample.
Evidence note: method, specimen build-up, result and limitations.
Care note: instructions for the named finish and restricted cleaners.
The receiving part of the example happens before cartons are distributed. One plank is placed beside the saved sample under the same light. Face finish, decor and visible edge are compared, and the carton label is retained if anything differs. Lanhe’s quality page describes raw-material, process, surface and packaging checks; the buyer can ask which record accompanies the shipment and whether it identifies the lot.

How to compare options for different project conditions
The example also shows why wear layer cannot carry the whole decision. If the matt option is 0.3 mm and the gloss option is 0.5 mm, a different observation could arise from finish, layer or both. A like-for-like surface comparison comes first. The layer can then be assessed for the project’s abrasion requirement, while a stain or chemical requirement stays tied to its own evidence.
When a project review is needed
A specialty cleaner belongs in the RFQ by name. Its label or safety-sheet description gives the supplier a defined input. The response should say whether the quoted finish was reviewed and whether the return is an observation, an internal comparison or a report against a method. That wording prevents the maintenance team from inheriting a broad sales phrase with no scope.
How Lanhe can support the sourcing discussion
Lanhe’s SPC page supplies the available surface and construction fields. Its quality page describes raw-material selection, precision manufacturing, durability checks, surface inspection and packaging integrity. Those pages help shape the request. Neither states a chemical-resistance method for every configuration, so the evidence request should name finish, wear layer, backing and lot.
A custom finish needs a dated physical reference. If sampling changes the decor or treatment, the earlier piece should be superseded rather than left beside the new one. The order line, signed description and inspection record then point to the same production setup. This is a traceability practice, not a claim that a customized surface has a standard test result.
Conclusion
The finished file answers a limited question: how did this identified surface look after this agreed exposure, and which lot arrived? Keep the quote, sample sheet, images, care note and delivery reference together. A later concern can then be investigated against a known configuration without extending the result to every chemical or cleaning method.
FAQs
Does a thicker wear layer automatically make SPC flooring stain proof
No. It is a construction value. The selected surface and exposure still need evidence.
Can a sample wipe test replace a laboratory report
No. A wipe can screen samples; a formal requirement needs its stated method, specimen and report.
Should buyers compare matt and high gloss finishes in the same way
Yes. Matt and high gloss are separate surfaces for approval.
