An acceptance checklist for limestone coating samples covering substrate, texture, lighting, technique, protection, and document matching.

Direct answer
Accept limestone coating against a physical sample under project or comparable lighting. Confirm color, mineral texture, sheen, edges, and post-cleaning appearance, and record substrate, tools, coats, and protection. Screen images are not final acceptance standards. If a third-party report is cited, confirm the tested model matches the proposed SKU.
Lock the variables first
Record substrate, preparation, product model, batch if available, tools, coats, topcoat, and viewing light.
- Substrate and flatness
- Color and texture target
- Tools and technique
- Topcoat yes/no
- Viewing distance and lighting
Judge texture, not only color
Mineral texture changes with trowel direction, pressure, overlap, and drying rhythm. Review near texture, far overall look, and side-light contrast.
Test contact and cleaning
If the wall will be leaned on or cleaned often, test cleaning on the sample and confirm topcoat compatibility. Do not extend a dry-wall sample to wet zones.
Match documents to the model
The published third-party report covers Limestone Coating WWD-7001A. After sample approval, state whether the purchased model matches the tested sample and how the report may be used.
Frequently asked questions
Can phone photos replace sample acceptance?
No. White balance, compression, and screens differ; approve a physical sample under project lighting.
How large should the sample be?
Large enough to show texture repetition, edges, and overall atmosphere; tiny chips are insufficient.
Does a compliant report mean the sample passed?
No. The report covers listed determinations for an identified sample; the sample covers appearance, application, and maintenance.
