Sealer Calculator

Floor Sealer Calculator

Enter your floor area, the surface and how many coats. Get the litres of sealer you need, the number of bottles and an indicative cost for penetrating or topical sealing of marble, granite, Kota, sandstone, terrazzo or grout. Indicative India 2026 — coverage varies, always do a water-drop test.

Your floor

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.

Coverage (sq ft per litre, per coat) by surface — your selection highlighted. Lower bar = thirstier = more sealer.

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.
