About kota stone sealing
Sealing, done the right way.
Sealing is protection. Most natural stone is porous — an impregnating (penetrating) sealer soaks into the surface and lines the pores so water, oil and stains bead up and sit on top instead of soaking in. It does not change the look or add a film; it buys you time to wipe a spill before it becomes a stain, and makes daily cleaning easier.
Kota is hard and slightly porous, with natural pin-holes and colour variation from green-grey to brown. It grinds and polishes well but needs its holes and joints grouted with a colour-matched slurry during the process, or the finish looks pitted.
The process
How kota stone sealing works.
Step 01
Test & clean
We test how absorbent the surface is and deep-clean it — a sealer applied over dirt seals the dirt in.
Step 02
Dry
The floor is left to dry fully; residual moisture stops the sealer penetrating.
Step 03
Apply
The right sealer for the stone and its use is applied evenly, worked in, and the excess wiped before it hazes.
Step 04
Cure & check
After curing we water-test the surface to confirm it is repelling, and give you the re-seal interval.

Frequently asked questions
Common questions, answered.
How often does stone need re-sealing?
Every 1–3 years indoors depending on traffic and cleaning, and every 2–3 years outdoors. The simplest test: drop water on the floor — if it darkens the stone instead of beading, it is time.
My kota stone has dull, grey, blotchy surface with no consistent finish — can sealing fix that?
Yes — that is exactly what sealing addresses on kota stone. We confirm the cause on the free site visit and quote the fix in writing. Seal after any polishing or restoration, when water no longer beads on the surface, before a stone floor goes into a kitchen or bathroom, or on new stone before it is used for the first time.
How do I keep my kota stone looking good afterwards?
The essentials: sweep daily — grit is Kota's main enemy once it is polished; mop with pH-neutral cleaner; avoid acid descalers. We leave you a written care plan for the specific finish.
