thanks for all the advice guys.
with regards to the tile choice, i like the 7 quid b&q tiles fine, double poo you say? why is this? Are they defective?
I did look at other tiles, i saw some nice ones, and many nasty ones, but the cost was huge. yes i am spending quite a bit what with the ufh, the boards and the levelling etc, but these costs would be the same whatever the tile choice surely?
I do partly agree with "you get what you pay for", but in all parts of life, its always possible to spend an awful lot of money on rubbish. Just because its expensive, could just mean that someone is making lots of profit.
In addition, if i was spending £45 a square meter on tiles, i probably wouldnt have a go at it myself. so the costs would increase further.
I put the marmox boards down today, i first primed with mapei eco prim grip, which seemed a good choice to go over the black adhesive residue.
The first batch of adhesive i mixed up turned out a bit too runny, so was hard to work with. the second batch was much better, but i seemed to be spending more time mixing than anything else, so i mixed up a whole bag to finish off the boards. i did waste a bit doing this though.
question... if i mix up a bucket of adhesive, when i need more can i just add more water and adhesive then mix? or should i clean the bucket first?
It all went fairly well, except i made a fair amount of mess. Due to the rough surface of the marmox, any adhesive spillage cant be fixed, but i assume if i get any whilst tiling i can wash this off with a damp sponge?
so tomorrow i am laying the UFH mat then going for it with the ultraplan slc. i originally planned on 2 bags (the room is just under 9 m2), but reading here, it looks like i'll need 3 at least?
I have 4 bags of the stuff sat here, so thats all good. although i'll need to simultaneously mix 3 (or 4) buckets of slc... unless i can put 2 bags and double the water in the one bucket? Onced mixed, how long have i got before i need to pour it?
I got some latex SBR primer with the underfloor heating kit that i didnt use (as i used the eco prim grip) should i use this on top of the boards? or go again with the Mapei prim grip?
Cheers guys
most tillers on this forum hate fixing the B & Q cheap tiles, there sizes are all over the place, and there very poor quality, nothing worse than fixing a floor knowing it wont last as long as a decent porcelain tile......but its your choice and I hope it works well for you..
