Porcelain installation

[RICHAS111]

Hi
We are going to be installing porcelain slabs next week and just have a couple of questions if anyone able to help. Planning to lay on a wet bed 6:1 (with sub base).

1. We understand that a bonding bridge primer is required. Can anyone recommend a decent one?
2. What type of saw allows for easiest/clean cuts? We will have to hire the equipment and then assume will need to purchase the special blade for cutting porcelain separately.
3. A few manufactures promote he use of Ardex Flex for jointing. Anyone have any experience of using this?

Many thanks
Suzie

1. larsen streetscape PS primer works well

2. a continuous diamond blade,these will cost a fair bit and need to be treated with care

3.I find it horrible to use,it goes off very fast and is hard to clean
however you can use tight joints

one word of advice,I wouldnt use a wet mix for porcelain,the slabs are very impervious,and can float around, a semi dry mix will be better IMHO

Thanks Luton,
Do you have any suggestions for a alternative jointing compound? Something that's easy to work with is important for us as its a diy job.

vdw 815 is a great finish IMHO
other may disagree but I like it
think you need at least 3 mm joints but 5 mm is better
