Should You Seal Marble Before Grouting

All natural stone tiles polished shiny honed matte or tumbled antiqued are porous therefore sealing before grouting is essential to fill these pores with protective sealer.

Should you seal marble before grouting. Marble sometimes gets circulary etches scrathed into its polished face with sanded grout. If this is not done minute particles of grout will sit in the pores and result in a hazy surface appearance. Can you please tell me what the issues or risks are with not sealing before grouting so i can make the call. Then grout anytime after the sealer has dried to the touch.

Should we seal our honed calacatta oro tile before or after we grout. If you must pre seal apply the sealer according to the product label but in such a way as to keep it off the edges that will need to bond with the grout. On the other hand if we seal after we can seal the grout at the same time. Then wait 3 days minimum after grouting giving time for grout to cure and then seal the grout.

If you seal the marble first then at least you have a better chance of using acid to remove any grout staining on the tiles cuz of the thin film of sealer between the acid and the marble. If you try removing any discolouration on the marble with acid then you re going to muck up the surface of the marble. Sealing the stone before grouting is also essential. While not all marbles are delicate most are highly absorbent and thus easy to stain and etch.

He will be using a light grey flexable grout. Polished marble shouldn t need sealing before you apply. On the one hand if we seal before it seems like we ll protect the marble from being discolored by the grout and make it easier to clean the grout off the tile. Mongo and bill do you have a view.

Use the normal grouting technique and let it dry completely before applying another sealer application to the tile and the grout. Because marble is a natural stone and will absorb color you need to seal them before you grout to prevent the grout from discoloring the tile. You can apply another coat of sealer on the tile too. Then grout using non sanded grout.

I used this sealer and just put it in a spray bottle and sprayed three coats on the ungrouted tile. However you have previously recommended to me that the tiles be sealed prior to grouting and i have read that recommendation several times in other posts and on other forums.
