............ so , i have glazed porcelain mosaic ( 50 x 50 on a 300 x 300 sheet ) the grout is going to be light grey / silver , and they are going to mounted on backer board , i was kind of hoping i could use some form of readymix addy but i suspect that i will not be able to , if that is the case then what would give me the best pot time , think thats it for now

hi paul you will want something with a good grab either bal mosaic fix or pci nanolite is what i normally use for maosaics mate

The Mapei Kera-Flex Maxi would give you the longest working tile I should think. Nice stuff to work with as well.

ok , so i am stuck to mixing this stuff up in a bucket , do i need to buy a whisk to go in my drill ?? , also , what do you reckon is the best trowel notch to use ??

It only takes a few minutes Paul! A whisk in your drill might burn your drill out I would just mix it with a bucket trowel, you only need a 4mm trowel so you won't use a lot of addy

so it is pretty easy to mix then , that helps , any idea what size bag i am going to need to do 3 square metres ?? , i was in topps today and they were wanting £55 for a big bag ( guess 25kg ) , surely i wont need that much will i

The problem is that you get a lot more for your money if you buy it in bigger bags. I dont use topps so I dont know what sizes they do but if your likely to use this addy in the future it might be worth buying a bigger bag then you need and keeping it for next time.

Have a look in CTD on Portrack Lane mate, they'll stock Mapei and BAL products for you and should be a bit cheaper than the Topps price you have.

If you can't get the Mapei Keraflex there (which in my opinion is your best bet) then ask for BAL Single Part Flexible - might be an idea to get white adhesive, which will be a little bit more expensive than grey, if your grout is really light coloured

Just remember to put the water in fiorst when you come to mix the adhesive.
