Sealing porcelain tiles

[andyb_987]

I would normally seal before laying .However I left my tub of sealer at my mates last week after I tiled his fire place.And I will get it back tonight -laying today hopefully.
have had a wee look around other threads to see if I can find the answer( I am sure its there) cant find it.

Is it ok to seal polished porcelain once it has been layed on the floor?


Many thanks.:hurray:

You might get away with it, depends on the tile I suppose. Adhesive is much more course than grout so it may not stain in the same way. Can you not get a temp sealer and try that?

some tilers only seal before grouting or after grouting,will maybe work if you hve worked very cleanly throughout!

i tend to lay then seal then grout and seal again depending on the tile if you do go for that then keep the tiles clean

 

[mhtiler]

i agree with lm ceramics,i do it the same way.

Polished porcelain is generally not too porous.
I would fix, then clean and seal, then grout. If the first lot of sealer was swallowed pretty fast then seal again, if it just sat on top then I just buff the tiles up after grouting.

Cannot see a problem in laying then sealing. Then grout. then re-seal.
LTP mpg pol porcelain sealer is very good for this. Pol Porc is not very porous at all and so seal needs leaving on a short while before buffing up to a shine.

if its cheap and nasty from b and q its a different story.

Pilkington recommend sealing their polished porc before laying, so I think a lot depends on the manufacturer.
