Onoff

Had a go on a bit of MDF: White is Forever White, grey is Mapei: Same tool, same nozzle. Go figure??? Doesn't help I've run out of beer...well, beer that I want to drink.

A bit nearer & cheaper? https://www.gumtree.com/p/guttering-drainage/soak-away-crates-/1326705345

Impey Aqua Dec's a great idea imo. The plastic former stays in situ after you've screeded. If I hadn't gone with my angle iron idea I'd have made something similar.

These are what I have. Even these in the hands of someone competent should do the job I'm sure. As soon as the grey is dry I'll rip it out and try again taking on board all the above.

Lidl’s finest Parkside gun. Pretty good imo...I'm the problem! This Mapei stuff skins up real fast. Doesn't help titivating over it.

Giving up with worrying over what it looks like. Day hasn't been a complete waste of time and mastic. I now know I can't tile OR silicone!

Well that came out like crap after trying to tool it. Wiped it all off in the end.

Filling the bath so I can grout that: What a damn good idea it was (@Nickfromwales )to fit the outside tap before the PRV!

That looks good. With hindsight etc! Going to persevere with this perimeter wall/floor joint as I am and see what it looks like.

Setting up for a hopefully neat silicone bead where wall meets floor. Tried masking to a 7/8mm tile first but figured that'll look too wide across the "flat": Very impressed with Frog tape in comparison to ordinary masking tape. Re did with a 5mm pack. I'll now run a very small bead of clear CT1 along the joint keeping it clear of the tape. When dry I'll go over with silicone, probably Mapei grey depending on how it looks.

Nice and neat. Did you mask it up?

I can't really be raking grout out for fear of going through the tanking just behind. It's got to be something that goes over the top.

"Interlock"...no mortar or "glue"? It never dawned on me!

I don't know about that, tbh its the main area that lets the side down imo. With hindsight I'd have probably aimed from the beginning for a 2% fall. Tbh I sort of did I thought. Calc'd a 13 - 26mm fall and reckoned I'd end up at 18mm from memory because of accumulative issues. There were constraints with bending the mesh down and worries over concrete coverage over the pipes. The use of the angle iron formers proved a great idea if I say so myself! Should be able to make out the fall lines: You can see the (decent?) fall here: It's got to be the tiling bed thickness where I went "wrong". Tbh the concrete was all dead flat due to screed rails being used so ideal or tiling straight onto. I should have used maybe a 6mm bed under the falls area and 10mm on the main floor!

A problem..... The right hand grout joint of the mitre is quite wide. I've got cracks in there as shown below. I half worried about this as I've ply behind the mitre. I figure it'll expand / contract at a different rate to the wings either side where there's no ply. The mitre joints btw were taped and tanked. Do I re grout, CT1, white silicone? Cheers

Done after a beer but looks like 14/15mm just over the 1% fall wise. See how it goes in practice!

Thinking about it I scored some blue 10'x5' sheets from site about 15 or 16mm thick some years back. I used them horizontally. Soundbloc I assume.

Latest message: "*** has finally agreed to pay for a plumber as it’s beyond me to fix it... I’m admitting defeat. Do you fancy doing it for some money? If not I’ll book a plumber in, didn’t know if you fancied some extra cash x" Tbh cash job aren't my thing. I'd have rather had a look FOC before now. Have to let her down gently.

Travis Perkins do 2.7m. I had them in green, moisture resistant for the bathroom. Why you may ask? Because some idiot when he put his new ceiling joists in ended up with 2470mm as a room height and didn't want silly little bits of pb at the top/bottom. "He" didn't appreciate the knock on of this meant silly bits of TILE...

I think my fall came it at 18mm over 1.4m so about 1.5% I'll throw the laser line on it later.

You want 1-2% fall I think.

Are you tiling straight onto the concrete? What thickness of tile?

There you go, that's me happy!

I didn't mean underground but fair heads up. Meant say where pipes come up out of the slab etc.

Cordless angle grinder is my weapon of choice tbh with a flap disc. You have to be confident with it though and I appreciate they scare a lot of people.
