Looks like i will be fitting 50m2 of the above tiles very shortly.Can these tiles be sealed prior to grouting? They are 10mm thick porcelain,available in multiple sizes and have chiselled edges and a rough surface which looks like they might be a nightmare to clean up the grout haze.
I have tried Bal temporary sealer on riven porcelain before,but with limited success,so need some ideas what to use to ease the grout clean up

Dont know the tiles myself. Do they need sealing? Might be that they just need a bit more care when washing off?

[swanman]

These tiles proberly wont need sealing

Just have a nice clean sponge clean water beside you and clean as you lay them

Do you use a wash boy?

[nybor62]

dont know the tile , as above dont think they will need sealing , as there not polished

Hi Swanman, Yes, I always use a washboy(and plenty of clean water)

[wrighty]

Hi nybor,No they are def not polished.But they have a grippy texture to them

[Alan.P]

As above, don't know the tile, a quick look on their web site doesn't throw much light onto the subject, you could always do a stain test on a tile prior to fixing. If they don't stain then just plenty of cleaning with the washboy.

[swanman]

Well that should do the trick

You cant go wrong with a wash boy

One little tip for you is just add a smidge of washing up liquid to the water it cleans off any grout and adhesive better

[swanman]

Thanks Wrighty

Good luck with the tiling job

[Rich]

If you are in any doubt then do a test or give the supplier a call. I dont think you need a sealer myself but as I have said i dont know the tiles. I would use your wash boy but keep another sponge in the bucket as well, I find that it is easier to remove the grout from the pits with a sponge. Just work methodically and dont grout to much at once, you dont want the grout going off on you to quick.

Not wanting to conflict advice with the above but I wouldn't use washing up liquid, never used it to wash off with before but I would be worried that it would react with/dis colour the grout. They should be fine to clean off with just water IMO.

[swanman]

No it dosent react to grout washing up liquid is very mild

All you need is a small amount

Try it you might be surprised

They don't need sealing. Just use plenty of clean water and then use micro fibre cloths. Grout them,wash them leave for about 45mins-1hr, wash them again just with a slightly damp sponge and then use the cloths to dry them. Lifts the haze pretty well.

Personally i wouldnt use washing up liquid to clean up,

Ive heard a lot of strange things over the years but never this.

I wouldnt use too much water either as this can affect your grout.

Run your washboy sponge as dry as you can get it, It will still have plenty of water in it though.

The only trouble we have had with grout haze is with Limestone tiles. These had loads of pores in them.

These ones http://www.google.com.au/url?sa=t&rc...XxUEvO8ionTbEQ

do they go darker when wiped with water(just wipe half the tile with a damp sponge )

I have heard if Fairy Liquid is added to s+c mortar(as a plasticiser) that it can rot the mortar!!!!

DO NOT add/use washing up liquid..

This product is an aggressive degreaser and will attack polymers etc in the adhesive/grout...

Use a grout haze remover if residue is left after clean up.... also adding a small amount to your washboy during clean up helps as well...

With this type of tile that has a rough surface then grout just the joint and try to keep the surface clean from excessive grout... a light wipe quicker than you normally would to remove the thick and then leave joints to set up, then clean down..

[swanman]

It not strange at all


Ive been using washing up liquid in water for 10years never had aproplem

but hey

Everyone has different methods

[jay]

If they are porous then just before grouting give them a light wipe with a wet sponge to stop then absorbing the grout

So does that make it right...?. if you wish to use that method then so be it but i cannot condone using such methods in the tiling game, one day you will be caught out and then you might also learn something..

[Dave]

Jay, they are glazed porcs and deffo not one bit porous... i have the same ones in Ocra colour on my kitchen floor..

Bugger missed any info on them being glazed .good thing your around Dave

[wrighty]

Just an update to the OP....these tiles were nothing to worry about.Cleaned up a real treat, didn't even have to use a rag to buff up the tile.Thanks all the same!

[John Benton]

Just for future ref. what i tend to do is grout the area and because the tiles are pitted, the grout obviously dries quicker than in the joints, I just go over the tile with a sponge and clean water being careful not to let the sponge touch the joint, leaving 3-4mm from the edge of the tile. It lifts the still wet grout out of the pitting leaving less work to do when you go to the joints. I find this works for ok.
