How best to Tile a room?

thanks chaps, the first challenging part for me will be putting on the SLC I guess.

..after you've confirmed there's no deflection in the floor of course.

Just caught up with this. Fascinated to see how this goes. My advice @mp3wizard is don't be a stranger, ask, ask and ask again, many on here happy to help out. Best of luck.

Back butter also. And leave space from the walls.

Hi All,

Installing Insulation boards

I have got the 6mm Deltaboards, so firstly I was going to sweep the floor clean, then clean the floor with a sponge, wait until it's dry then paint the entire area with heatflex, once dry I was then going to lay the boards in a brick fashion, I was going to use 15 25mm screws on 35mm washers per board at 300mm differences to fix the boards down, once fixed I was then going to use some special thermal tape to tape the joints, and put a light skim of tile adhesive over the joints as per 3-falls picture on page 2.

Are there any problems with my plan so far?

I understand that I need to leave a 5mm gap all around the edges for expansion/movement is that correct? and because I will be looking to put the SLC ontop, would it be wise to purchase and install the spongy foam spacers all around the room for this purpose? because I'm worried that when I pour the SLC out, especially around the bifold doors that it will just go into the tracks if I don't protect it...

Your half way right, your best sticking the boards with tile adhesive as well as screwing. Use a 6 or 8mm notch trowel, no dot and dab.

The bigger the tile the harder to fit ,best get someone to do it ,just being honest ,good luck

The expansion is around perimeter only.
The adhesive is to stick the board tapes down.
Word of caution, slc is not completely self levelling, you can easily easily make it worse!
Research techniques first.
If you can get help, do so.
On average consumption rate is 1.7kg per mm per m2 make sure you have enough.
Mix exact water quants as per instructions, mix and let it rest for 2-3 mins, mix again and use.
Get a mechanical whisk that inserts in to a drill, and a spiked roller.
The roller will expel excess air and help level it.
Topps will sell them.

all around the perimeter yep, would the foam be the best method to avoid getting slc in the frame of bifolds?

 

[Flintstone]

Yes or expanding foam if there are large gaps

I've got 5 x 25kg bags of slc, that should be enough shouldn't it.
