Coverage assumed: 225 sq ft / litre / coat for this surface (Dense, sealed surface — drinks little.). Soaks in, no film — best for natural stone. Coverage varies hugely with porosity, finish and how it's applied — test on a small patch first.

Protect your stone floors the right way
DesignAI can recommend the right sealer, finish and resealing schedule for your stone, climate and traffic.
Coverage varies. Real sealer usage depends on porosity, finish, temperature and application method. Do a water-drop test (water that soaks in = needs sealing) and seal a test patch to gauge actual coverage before buying in bulk. Porous stones like Kota and sandstone often need an extra coat.
