Marble is porous. Coffee, tea and oil seep into the pores and leave dark stains that are hard to draw out. A sealer fills those pores, so a spill sits on the surface longer and you have time to wipe it before it gets in.
What a sealer protects against
Coffee, tea and coloured juice stains.
Oil in the kitchen and around the dining table.
Water rings in entrances and bathrooms.
What it does not protect against
A sealer does not stop acid etching. Lemon and limescale remover still eat the surface through a sealer. We explain this in why acid ruins marble.
When to apply it
Right after grinding and polishing, with the floor clean and fully dry.
Kitchens, majlis rooms and entrances first, since they take the most spills.
Renew it every one to two years, depending on use.
