Onoff

If you go 150mm centres then about 68 per full board sitting over 4 vertical studs at 400mm centres. At 200mm centres then 52 screws. Squirt some low expansion foam in the gap behind the batten and cut flush with the batten when dry. You can patch plaster the missing area later on. Shouldn't affect what you're doing now.

My wet room corner is 1400x1400. If too much water escapes outside this area I'll be back here looking for door / screen ideas!

This will be the second one of your sermons I print off and laminate for future reference. Mainly so I can keep reading until I fully absorb it all!

Another m2 'ish done as per the Welsh Wizard's expicit instruction! I actually got brave tonight and LIFTED 3 tiles I felt were low. More muck and re-levelled. It's not the best but it's the best bit yet! Had to trim 3 tiles that were tight when I dry fitted them tbh. Out the door tomorrow hopefully!

I do NOW! Before I thought you'd made a typo! I'd be fitting them portrait. If you can find what Jewson code, on your invoice maybe, it is then you might find the manufacturer's part number. If it's: 01129/0 then its "4TE" as in 4 tapered edges.

Just got another 4 bags of adhesive (£11/20kg), can of primer and... Naughty, naughty, very naughty!

Yep & yep

Primer.... If I've already primed an area but then not tiled it, should I prime it again circa 24hrs later when I come to to tile that bit?

@CC45 try Palace Chemicals Ltd in Liverpool for this, the stuff I have. EDIT: Think I'd just get that £12 one you linked, flexible, good for UFH, long pot time. Ardex is a good brand I think. Just looked at the £18 one and it's non slip. Presumably less worries about it sliding down the wall.

Bit of Unistrut, some studding....I have an idea! (I'm not kidding either!)

330x330mm tiles. 3mm spacers, 6mm trowel, this one: https://www.screwfix.com/p/rubi-open-handle-6mm-notched-steel-trowel/6228F? I also have the 10mm version of the trowel.

Guess so...where are you?

Hasn't yet killed my 25 year old Wickes (aka Earlex 1000) vac...

Laticrete 335 I paid £11 / 20kg

You'll want: - self adhesive tape (T'station 61291 £3.65) - a wide filling knife (T'station 25000 £5.39) Next day free delivery at TS over £10 btw. - joint filler (Gyproc Easi-Fill for example). Shop around. Can get ready mixed or powder. I splashed out on the Mirka sanding kit at Toolstation. It's excellent. Attached to a Hoover and is virtually dust free. Lidl occasionally do a cheapo version.

@Nickfromwales, page 1 of this thread: The top of the timber for the pocket is 366mm from the datum i.e 378 - 12.5. NOT 378 as @Construction Channel kindly picked up on. Still processing your words of wisdom!

Because you don't have a depression where the boards meet, if you taped then filled you end up with a shallow "hump". The skill is then feathering this out so it's less noticeable. Sorry, I really don't know what it would end up looking like! Or as Peter says fill and use lining paper but that's more faff/time etc. Try it I guess if only a small area. I wonder if you should be running a bead of No Nails type stuff where the boards meet...? Someone else will dive in shortly... I hope!

I wonder if you could fill the cracks with say molten solder then seal over the top...

Wade through this from the beginning, enjoy! https://flic.kr/s/aHsk23FYzd

I'm getting there I think. Looked this morning at the bit I did last night and happy enough. Interesting how a tap on the setting tiles last night rang a little "hollow" but this morning they seem rock solid. Like the adhesive has sucked them down or something? One bit tonight then out the door Weds night hopefully. GROUT Grouting Thursday night so what do I need? I have buckets & sponges. Think I've a grout float in the shed though God knows where it came from or how old it is. Must have been from my last foray 30 years ago! I've been looking at it for years trying to figure what it is, photo later. Any tools, rubber spreaders etc that'll make this easier? I have time to get anything. Mop head. Came across an abandoned, dusty, traditional mop head. If I can sneak it through the washing machine I wonder if it'll be of any use? WALLS Probably popping to the tile place later this afternoon. Figuring to get another primer and a couple or 4 bags of adhesive and maybe one grout. The Laticrete 335 is seemingly OK for the walls. Not sure if I trust their data sheets tbh, coverage seems more like half that stated. Maybe it's if you don't back butter is the figures they're giving? Whereas previous stuff I read termed a large format tile as >300x300 I came across this on their site: "Back butter large tile >200 mm x 200 mm to provide full bedding and firm support if required". My wall tiles are 400x250 and will be laid horizontally. The 335 has a 30 minute open time. Loads of questions keep popping into my head! I presume to start "one tile up" or maybe even just under the pockets to ensure they look spot on then cut the bottom tile against the floor... Got a 6mm and 10mm trowel, which is better? How many rows can I lay without it slipping? Drilling big holes in them...for pan inlet/outlet... Sorry Nick, it ain't over yet!

Didn't I sketch what a tapered edge board looks like? And write "tapered"...with an arrow...28 July? If I pm you my address can you send me some of whatever you're on?

Out of interest can you extend the set time of rapid set tile adhesive with cream of tartar?

I did ask if I could have the sieve for recycling and sifting blast media! -What really pi$$es her off is... - taking what I thought was the old washing up bowl for engine/gearbox oil changes, - nicking her cheap crappy plastic brooms / dust pans (and breaking them). Along with "loading the dishwasher" / "folding the towels" the wrong way...."not filling the water filter up"..... The list is endless tbh...

Why not, more absorbent?
