First tiling job - spookily similar to dantheram's thread

[Colour Republic]

Also you may want to check about priming the boards as it is required.

normal order is to prime the boards, lay the heating, don't get dust on the floor then SLC

like I said ive covered loads of heating mats and always allow 2/3m2 per bag..

 

[dantheram]

I fear you're going to be a bag short there at least.

yes on paper your mathematics work. Sub floor + 2mm heating wire + 1.5mm of SLC over = 3.5mm. However unless all of your heating wires are perfectly laying flat to the sub floor (which I have never seen!) then some will be poking through the top of your SLC at 3.5mm, also keeping in if you have used a heating mat that adds another 1mm. So now your playing with 0.5mm of SLC over the wires. Now unless you're some sort of SLCing God, it's never gonna happen!

I'd allow for minimum of 5mm SLC and even then I'd like a spare bag as back up.

thanks for for the advice. I've got another bag to give 5mm SLC

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

Just looked at the floor primer bottle and it says it should be applied 12 hours prior to the heat mat being installed.

This isnt going to work for me and i need to get the floor levelled tomorrow too... should i use the prim grip instead?

Thanks

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..

 

[Chalker]

Gorilla buckets are great for mixing slc.

There's lots of information on how to do each of the stages of the job that you're doing.
Lots of products, lots of tools, lots of advice from tech people, and on here obviously. You can check and double check...

But tiling isn't as easy as it looks. As it sounds like you are experiencing.

Good luck with the diy project and hope it turns out successful.

Question about the perimeter - obviously I'm leaving a gap (5mm) where a insulation board meets a wall so do I maintain this gap when I pour SLC? So erect a dam around the entire SLC area or leave it to fill the wall gap? I'm 99% certain this is a stupid question but just checking.

 

[dantheram]

How's this job coming on?

Mine is complete now - posted a few pics on the thread.

Just bumping some of the older popular (sometimes not so popular) threads. Probably wont be current discussion these days but I just need to do it. So just ignore the thread if it's not current for you.
