Advice needed for mosaic splash backs

[Rob70]

Hi,

I'm looking for some tips on installing mosaic sheets, they are going to be installed in a kitchen as spashbacks. I'm looking for advice on planning and how to cut them in around sockets. Also how to get them flat to the wall without them dipping and bowing out. I think they are glass material but will update when I seen them as I'm installing them for my son,

Regards Rob

What size are the mosaic pieces and how are they held together? (Paper faced, mesh etc)

They should be a doddle to cut around sockets.

Use a thin bed trowel for mosaics. There are mosaic backing sheets available to prevent slumping which require a slightly thicker bed of adhesive

Thanks for info, I will update when I see them tomorrow, thanks

Just use a decent white cement based adhesive (do not use a rapid set) and they shouldnt slump, if you find they are then just cut the sheets in half. When going around sockets etc just cut sheets into sections, no need to struggle with a whole sheet. The wall needs to be completely flat you cant use adhesive to pack them out as youll only be using a small trowel and itll get messy. Trowel size will depend on size and thickness of mosaics. 3 or 4mm are common sizes.
Backer sheets arent worth the hassle, the adhesive will need to go though the mesh and make contact with he mosaics.
Use a grout float to pat the mosaics flat.

Do the glass mosaics have a coating on the back? If so not all adhesives are compatible with the backing. Also the stone may need sealing.

I have used these before and I can confirm you are in for a headache...

Alot of the mosaics are stuck on squint, slightly different sizes. I ended up sticking them on and going back with a Stanley knife to cut and fix the worst offenders. Best of luck.

Dynamic, how did you cut around sockets etc ?

Yes, I can confirm that the glass has a white backing paper on them, can you link me a suitable adhesive and sealer ?

Use a Stanley knife to cut all the 'whole' tiles out that work in cuts at the socket. Once you have stuck your sheet on minus the socket tiles, go back and Mark the socket tiles, cut them and stick them.

You need to check with manufacturer/supplier.

Have a look at Mapei, AdesilexP10. Or P9.

 

[GoneGuy]

Mapei adhesives are readily available in most screwfix stores.

Can anyone advise on best way to cut these small mosaics, I'll cut out the sockets size and I will need to fill in the rest of the socket with the cut mosaics ? Also would I need a centre point as these are for splashbacks around the kitchen?

 

[GoneGuy]

I use montolit tile and glass nippers.
And I also centred as usual but best to ask @MissTiler.

I use Leponitt glass nippers to cut glass plus Rubi porc nippers to cut stone mosaics and chunky glass etc, also a Montolit cutter with a mosaic mat, plus a grinder with a glass blade.

I'm going to start the tiles at the worktop edge and as these tiles don't have a straight edge is it best to cut them in or cut the sheet down so its level with worktop?

Actually, would like some advice on the best starting position, i.e the centre of cooker between hob and fan or at worktop edge ?

it depends on which kind of edge finishing are you looking for. If the cut will be exposed I recommend a specific blade (that is slow) but is capable to give you factory edge on Porcelain, glass, stones and even metal mosaic. The blade is our Montolit CPF Perfetto. If the cut won't be exposed, Montolit Masterpiuma or Minipiuma + rubber Mat item 58 will work. You'll need a nipper to cut the stone pcs
