Common Questions

FAQs — PR-602

What is PR-602 used for?

Natural stone and marble facade sealing, granite and stone cladding joints, stone flooring and stair edge sealing, and decorative stonework joints.

Will PR-602 stain the stone?

It uses a non-staining formula with 92% elastic recovery, designed to protect stone facades from permanent soiling. As with any stone project, test on an offcut of the actual stone before full application — porous stones vary.

Why is staining such an issue on stone?

Porous stone absorbs the plasticizer that some low-cost sealants bleed, and once it has migrated into the stone the mark is permanent and cannot be cleaned off. PR-602 uses a non-migrating system to avoid this.

What standard does PR-602 meet?

GB/T 14683-2017. Test report 2022MC076 is available on request.

What is the MOQ and lead time?

Standard OEM and private label MOQ is 1,000 pcs per model, with mixed-model trial orders from 3,000 pcs total and stock items from 500 pcs. Typical lead time is 15–25 days after artwork and sample approval.
