Beside this, how do you seal marble tile after grouting?

Use an impregnating sealer for best results.

1. Fill a spray bottle with a commercial stone cleanser or a mild, pH-neutral cleanser.
2. Sponge a thick, even layer of marble sealer onto the stones.
3. Wipe the excess sealer off the marble with a dry cloth after 15 minutes.
4. Apply a second coat of sealer and repeat the process.

One may also ask, what happens if you don't seal marble? In addition, if the marble is not absorbent, then it will not absorb the sealer, and the sealer wont work. Sealing the marble will reduce the chances of hard water stains from setting in, or at the very least make it much harder to accumulate calcium and lime deposits over time.

Also question is, do you need to seal polished marble?

If my marble surface is polished to a high finish, does it still need to be sealed? Yes. Marble and natural stone regardless of the finish is still porous and is susceptible to dirt penetrating the surface and staining. The surface still should be sealed with a penetrating sealer.

How often does marble need to be sealed?

3-6 months
