Porcelain from China

They might be pre-sealed....if they are shiny then NO wax coat is on them...

polished porcelain needs an impregnator to seal open pores that are exposed in the polishing of the tiles...but some tiles are pre-sealed..check on the box..sometimes it say's product is factory finished/sealed..summit like that.

Cheers Dave - I'm sure it says on the box that they need a sealer, however that could be them covering their rears. I'll oil and butter another random tile tonight and whack a bit of grout on - see how it goes. When you apply a proper sealer can you see it being absorbed? I can imagine it running straight off the surface.

I'm only a DIYer but have tiled a wet room in natural limestone and laid a couple of floors - 1 in slate and 1 in porcelain (The latter not being as highly polished) Limestone was a nightmare but happy enough in the end) The slate's over electric underfloor heating well pleased. The porcelain floor was a mate's kitchen - he's V.happy.

If it say's on the box to seal then use an impregnator suitablr for porcelain....leave it to dwell on the surface for about 15 to 20 mins then buff of any excess...you will be fine after that....the impregnator helps with the cleaning of the tiles in every day use...as dirt cannot grab into the open pores...totally different to working with stone...

I've laid some chinese porcelain before and could'nt even wipe off my felt tip marks. they were pants. also had black grout stain a porcelain tile too, so i'd definately seal them mate.

I fitted polished porcelain last week,600x300 brick bonded,then done glazed porcelain 600x300 herringbone in next job where i still am fitting 600x600 glazed porcelain of the same sort(american is the name,spanish made),top notch when cleaned up,my customer had a shine on by monday morning like nothing normal:smilewinkgrin: so i think ill let him finish the 50m2 of 60x60,the grouting took most of the wax off,i heard that dry grout rubbed about on the face works for removing wax?? anyone else heard this?

Did the same again to a randomly selected B&Q Chinese 600x600 milk chocolate porcelain to make sure (Whacked butter, cooking oil and shampoo on making sure it was on the edges and let it sit overnight) Wiped straight off no marks. Maybe I have a good batch. Move on to the next step I think - will let you know how it goes.
