K-PROOF®

The sealed premium line

K-PROOF® is the exclusive line of natural stone quartzites sourced from quarries worldwide and carefully selected by Marmotex. A single treatment seals every slab permanently.

What K-PROOF® does

Waterproof

The seal closes the pores — water, oils and acids no longer penetrate.

Food-safe

Certified for direct contact with food. Ideal for kitchen worktops.

Scratch- and impact-resistant

Quartzite is among the hardest natural stones. K-PROOF® reinforces that natural resilience.

Stain-resistant

Red wine, coffee, lemon, oil — they leave no mark and wipe off without effort.

Identified by the mark

Every treated slab carries the K-PROOF® mark. It guarantees that the single treatment is genuine and that the slab comes from the Marmotex selection.

The 13 K-PROOF® quartzites

All K-PROOF® materials are fully hardened quartzites — impact- and scratch-resistant by nature. The treatment adds the one property they lack: resistance to staining.
