Sealing Polished Porcelain Tiles - TilersForums.com

Hi.
I have just finished laying a 30mtr floor using 600 x 600 CIMIC polished porcelain tiles.(Hards as nails and a nightmare to cut. )
The customer purchased the tiles and was told that they are double fired and they do not need any special aftercare.
The customer is now telling me that someone else has told her they have to be sealed.
Any advice would be appreciated. thanks

Polished porcelain needs to be sealed with a good impreganator sealer.

I use Fila porcelain impreg sealer, lay the tiles, give the the full floor a good coat of impreg sealer then grout.

Reason you seal polished porcelain is that the polishing process open millions of tiny hols in the tile surface and dirt and grime can get into them and cause dulling.

Matt porcelain needs sealing too.

so do you lay the floor then put the sealer on then grout?

I thought you sealed the tiles individually. dunno why I thought that but I assumed so lol.

With polished porcelain that is the way I would do it. Slate however, would be a different matter........

so lay, seal, grout? cheers.

got a porcelain floor job coming up and was just wondering

mate at TOPPS says I wont need to seal them though but they're polished so I dunno why they wouldn't need sealed.

You might find the tile manufacturer gives instructions with the tiles, maybe they say don't seal. Normal to seal polished porcelain though.

Be carful though. I sealed polished porcelain using a roller and it left too much on the tile which i then spent the next morning rubbing off. I would advise using it on a cloth and putting a thin layer over the tile just to seal the pours.

Then again i'm the forum muppet so your best off listening to the others lmao.

Test test and test again. Get an offcut, put some contaminates on it (things that are likely to get spilled on it) - tea, coffee, ketchup, vinegar or anything. Leave it on for a few hours, wipe it off and it it stains it will need sealing.

Apply with sponge / roller etc, leave it to fill the micro-pores then wipe off with a dry towell before the sealer dries. Could also give the grout a seal with the same method. Job done.
