Looking at the pic and seeing that the tile is 45cmx45cm, I'm guessing there are 4 stars per each individual tile? To keep the effect of individual smaller tiles it looks like you could get away with a cement grey coloured grout, personally I think black would be too stark against anything other than a black tile. I'm based in Cornwall but at the moment just so stacked out to take anything else on (will already be working Good Friday and Bank holiday Monday, plus have smaller jobs to fit in when I can). Sounds like could all be pretty much done in a day. If you were really stuck and could hang on I have some outside tiling during April. If the weather's really bad might be able to do it then.
I think you might be right, now I'm considering silver grey or manhattan grout. I think we'll probably do it ourselves, I'm breathing, sleeping and eating tiling at the moment so I can't imagine going back to blissful ignorance as just a client now.
Could you comment on my plan of events? I'll recreate it below so you don't have to scroll back:-
I'm thinking we sand back paint to 90% gone,
apply Bal Prime APD or BAL bond SBR or Mapei primer G (anyone got any thoughts on picking between these, is price a good enough reason?) to surface,
cut tiles,
use a 10 mm (would 12mm be better?) notched trowel to apply Mapei Keraflex Maxi Flexible S1 adhesive,
stick tiles on, probably turn air blue in process,
regret ever beginning this, lose will to live, drown sorrows.
Wait until next day for adhesive to set,
Mix and apply Mapei Ultracolour silver grey or manhattan grout while wearing gloves and make sure to clean it off super good using endless buckets of water and a normal sponge? Or some kind of special, magic sponge?
Does that sound right? Should ceramic tiles and grout be sealed with something afterwards? If so what would you suggest (brand name etc?) I was led to believe by other thread that it should be Keraflex Maxi S1 and not Keraquick because of the size of the tiles, is this correct?
Thanks a lot.
