Why seal marble and granite?
Both marble and granite are natural stones with tiny pores that can absorb liquids, leading to stains if spills sit. Sealing applies an impregnating treatment that fills or coats those pores so spills bead on the surface long enough to wipe away. Marble, being softer and more porous, especially benefits; granite is denser but still benefits from periodic sealing. Sealing doesn’t make stone bulletproof, but it buys time and keeps worktops, floors and vanities looking fresh.
How to seal marble step by step
First, learn how to seal marble in order: clean the surface with a pH-neutral stone cleaner and let it dry fully (ideally 24 hours); choose a penetrating (impregnating) sealer suited to marble or granite; test it on a spare offcut; then apply an even coat with a soft cloth or pad, let it dwell as the maker directs, and buff off the excess before it hazes. Apply a second coat if the stone still absorbs water.
Choosing the right sealer
Use a penetrating (impregnating) sealer — it soaks in and protects from within while keeping the stone’s natural look and breathability — rather than a topical coating that sits on the surface and can peel. For kitchen worktops choose a food-safe sealer. The same type works for both Egyptian marble and granite; just follow the product’s coverage and dwell-time guidance.
How often to reseal
Resealing frequency depends on the stone, finish and use. A simple test: drop a little water on the surface — if it soaks in and darkens within a few minutes, it’s time to reseal. Porous marble and busy kitchen worktops may need it every 6–12 months; dense granite and low-use areas last longer. Honed surfaces absorb more than polished, so they may need sealing sooner.
Care after sealing
Sealed stone still needs gentle care: clean with pH-neutral products only, never acidic cleaners like vinegar or lemon (which etch marble), wipe spills promptly, and use coasters and chopping boards. Avoid abrasive pads. These habits, plus resealing on schedule, keep Egyptian marble and granite looking their best for decades.

Frequently asked questions
How do you seal marble and granite?
Clean the stone with a pH-neutral cleaner and let it dry fully, choose a penetrating (impregnating) sealer, test it on an offcut, then apply an even coat, let it dwell and buff off the excess before it hazes. Add a second coat if the stone still absorbs water. Use a food-safe sealer on kitchen worktops.
How often should you reseal marble or granite?
Reseal when water dropped on the surface soaks in and darkens within a few minutes. Porous marble and busy worktops may need it every 6-12 months, while dense granite and low-use areas last longer. Honed finishes absorb more than polished and may need sealing sooner.
