DIY Tiler - 90 sq m of large format porcelaine tiling making me nervous!

[PJPro]

Sorry, I'm deffo getting bogged down here, I'll re-read the posts,if you have a mixture of wooden and concrete / screed floors then yes, you'll need a decoupler on the wood and advisable for the screed, and also an expansion joint between and directly over where the substrates meet.

Apologies Alan.P. I am probably not explaining myself well.

The upstairs bathroom is wood topped out with No More Ply. There are no transitions to any other substrate.

The downstairs, featuring a hall, downstairs cloakroom, dining room and kitchen, is concrete/screed with underfloor heating. There are no transitions to any other substrate.

OK. The tiles arrived today. There's 64 packs each containing 5 tiles. The pallets wouldn't fit through the back gate so I had to lug them through by hand. Man, they're heavy. They're stacked up in the back garden on a couple of pallets and covered with thick plastic sheeting held down with bricks. There were two boxes of tiles which are broken, so I'll have to return them for exchange.

The adhesive is Topps Trader Quick Set White....not BAL. Is this any good? The manager at Topps agreed to swap any bags I wanted to change, so have the option ot upgrade to BAL if I choose....but suspect it would come at a premium. I've been supplied with 20 x 20kg bags.

The grout is BAL Super Flexible Ivory. I've got 5 x 10 kg bags.

I'm going to start laying tiles in the upstairs bathroom later this week so I'd be grateful if someone could answer a few more questions.

Do I need the Dural matting on the floor (chipboard topped with NMP)?

Should I lay the floor tiles first or the walls? I was thinking that I'd prime the walls, fit the waterproof membrane to the walls around the shower and then crack on with the floor.

I am uncetain whether the tiles are covered in transit wax. How can I tell? Do I need to clean the wax off before I lay the tiles or can I do it after I have laid them but before I apply the grout?

 

[White Room]

Do mean Topfix adhesive, never had a problem with it

 

[PJPro]

No, I mean this stuff. Link Toppfix Rapidset Flexible White | Topps Tiles

OK. Here's a few pictures to to illustrate the job. The work is more advanced than the pictures might suggest but, unfortunately, I don't have any later photos which are relevant to this thread.

The first picture shows the downstairs cloakroom. It's 2m x 0.8m and around 2.4m high. Clearly, the photo is taken from above. The second picture shows a part of the hallway which will also be tiled on the floor. The final picture shows the upstairs bathroom. It's at the far end of building and starts directly after the red RSJ. It's about 2m x 3m and 2.4m high and is located above the downstairs cloak so that it can share the same stench pipe.

Not had the chance to read all this thread but have perused it enough(i think).

Honestly and truthfully this job is way to big for a diy job(way to big),the money your going to pay on tools alone,would go a way to paying a pro then the astonomical prices topps charge on top of that,i done a job last week were i knocked £15 per bag off what the client was quoted and still made a little.

I think the money you would have saved hiring a pro,would have outweighed the cost of you doing it yourself(imho).

 

[doug boardley]

...but at least if PJ wantsto tackle it himself he's come to the right place for advice

 

[mz30]

wholly agree doug with him comin to the right place,however its hard to explain to a guy next to you the work involved in this project (apprentice etc).never mind explaining it on the internet.

No diy'er in my opinion should take on this sort of project,when the money he has to spend to do the job and the money he has already spent,will outweigh the pitfalls he will hit and regardless of all the info he is given,he will hit problems beyond what he knows .

Pj am not trying to say you shouldnt do the job by any means mate,what am saying is weigh up the consequences,your spending x amount of money on materials ,tools etc,and you have spent time on here asking how you should do said job.

You want a professional finish but given the size of the job and the materials your using,from what i can gather your not confident you can deliver that.

Well, I'm committed now! Just spent about £800 on tools! 😱mg_smile:

I'm feeling a little more relaxed about the whole thing. What's the worst that can happen (don't answer that)?

The plasterers have started dry lining in the bathroom. They're putting up green board (a moisture resistant plaster board) in the bathroom with normal stuff elsewhere in the house. We had a bit of a debate about using aquaboard instead for the bathroom but somehow ended up back the green board. They were intending to put a skim over the top but I've asked them not to bother...as I'd have to wait however many weeks for it to dry before tiling.

I'm going to buy some BAL APD primer tomorrow and will slap that on all over the walls. I'll also talk to my local tile shop (who supplies the trade) about suitable waterproofing in the vicinity of the shower. My concern is if I use membrane I'll make the wall thicker due to the adhesive used and it'll give me more difficulties later. If I can get away with it, I'd rather use a paint on solution with tape for the corners, etc.

I'm still not sure if I should be using the matting on the bathroom floor...this question has gone unanswered for some reason....so I guess it's either not needed or requires a complex answer. Clearly, the retailer is gonna want to sell me some so I'll have to make a judgement on the spur of the moment, weighing up the costs against the likely impact of not using the matting.

I understand where you're coming from mz30. The pro tiler would have come in at around £3K to do the whole job....and as I've read in many threads on this forum, getting in a pro doesn't necessarily mean a good end result. That said, the guys working on site seem like nice fellas and know their trades, so I suspect the tiler would have been a good guy.....that's why I used the PM that I did....to identify the good tradesmen and avoid the duffers. Sometimes I perceive the work as being a bit, err, sloppy, but most of the time it's just me wanting perfection in areas that don't really matter.

I suspect my attempts at tiling will be far from perfect. But I hope, with the help so generously offered on this forum, I can get the fundamentals right so at worst I end up with a bit of lippage, sloppy cuts and the odd poorly fitting tile rather than tiles falling off the walls or lifting from the floor.

That said, I'm grateful for your concern and welcome your advice.

 

[PJPro]

OK. Some more up to date photos taken this evening

Looking from the kitchen into the dining room. This whole area will be tiled. Hopefully, you can see the door liner on the right. This leads to the hall.

Looking through from the dining room into the hall. To the left is where the stairs are going in. This whole area will be tiled.

The stairs will go here. They're being fitted tomorrow.

Here's another picture of the hall. You'll notice a door liner on the left. This leads into the downstairs cloakroom.

Here's the downstairs cloakroom. The floor and walls will be tiled.

The next few photos show the upstairs bathroom with the green board on some of the walls and the moisture proof chip board on the floor. The NMP has yet to go down on the floor.


I've surveyed the walls with a straight end and it seems they are each flat but there's an angle at the join of the boards i.e. they are not true with each other. I'm going to speak with the plasterer tomorrow but I suspect they would ordinarily take this lack of trueness out with the skim coat. It looks like I'm going to have to take it out with adhesive, possibly applying a scratch coat?

I'll see if he can do better on the remaining bathroom walls.

Everything was purchased from TradeTiler except for the drills, which I bought from 365Drills.

I have a lot of additional gear already (grinders, drills, drill press, levels, various hand tools, safety gear) so this above does not necessarily reflect what I think I use on the job.

 

[DHTiling]

It is a tapered edge board.. and will be fine.. Make sure you tape the joints.

 

[Bathfix Bob]

Are you saying when you offer up the straight edge to the two moisture resistant boards there is a V shaped hollow? Is it just in the middle (tapered edges) or accross the whole boards?

I've done my fair share of plastering and never not got two boards flat with each other when dot & dabbing.

Edit: Ah my 100th post, nearly catching up to you Dave!

 

[White Room]

The boards need to be laid flat rather than leaned against the wall

 

[Dan]

I thought that you know.

 

[PJPro]

I've had a word with the plasterer and, using one of his long straight edges, the boards are almost perfectly flat. I told him "spot on" would be adequate ;-)

The bad news is that the plumber is moving house today and won't be back in until Friday. This means I won't be able to do the setting out to ensure that, for instance, the flushing plate for the wall mounted toilet falls across two tiles, enabling me the cut them. The setting out is actually going to be quite tricky. I need to consider where the tiles will be pierced by pipes, where they will meet the ceiling and where they will meet the doors and windows if I am to avoid silly thin slithers of tile which I will be unable to cut.

In fact, I think the actual laying of the tiles will be fairly straight forward (fingers crossed). From where I sit today, the biggest challenge appears to the setting out, especially as the walls/floor all seem to be more or less flat. I intend to spent a lot of time working out where to place the bottom baton and the vertical alignment of the tiles before I actually commit to laying any tiles. If I get this right, I hope to avoid insurrmountable difficulties later.

 

[doug boardley]

while you have this downtime PJ I'd suggest marking some datums on your walls then, I'd find the centre (vertical and horizontal) and level them round (and up). Then make yourself a guaging staff so that you can get an idea of where your tiles will pan out.

 

[PJPro]

Thanks for the advice. I'll do that. I also need to get my primer and waterproof solution. I'll use BAL ADP for the primer and am considering BAL WP1 and tape for the waterproofing. I intend to get that on the walls as soon as I can.

 

[PJPro]

Well, I've got the BAL ADP and a BAL Showerkit. The latter was on a special trade deal at The Tile Source (£39?) down from £75. I provided a card from one of the builders on site (with his permission) and got trade prices. Also got some trim but couldn't get a threshold I liked.

I asked about sealant for the grout and they didn't have any. I forgot the tape and the wax remover (doh). I'll use someone more local tomorrow to get the last bits a pieces.

 

[PJPro]

The builders on site are keen to see what sort of mess I'm going to make of the tiling. Clearly, as the client, I've been doing a bit of snagging of their work along the way. This is their opportunity for a bit of payback. It's all in good humour and the foreman has been giving me the benefit of his advice where he can. Apparently, they are going to give me a score out of ten.

[jay]

this could be good

 

[PJPro]

this could be good

Well, he does oversee jobs where pro-tilers are used so he knows the materials they use and has observed them going about their work. But I know what you're saying.

 

[PJPro]

I've marked out the walls to arrive at the centres and drawn floor to ceiling lines at each centre and the horizontal line all around the wall. I need to make up some guide battens to start sussing out how I'm going to set these tiles out.

Oh, the drills from 365Drills arrived today. Seems they bunged in a free guide with a suction cup for the 80mm bit. It's too small from the 120mm but, then again, I'll be using my drill press for that.

Nothing from TradeTiler yet so I'll be unable to make my guides battens until the delivery arrives including the spacers. I did expect something today.

 

[Bathfix Bob]

PJ, Have you received your text yet from Trade Tiler? He texted me to say my box was on its way.

 

[PJPro]

Received the goods today. Looks like it's all there. The clinker is, err, massive!

 

[PJPro]

Just had a go with the clinker on some large format (600x300) 10mm porcelaine tiles I've got hanging around. It was a reassuring experience. I managed to cut strips down to about 20mm without difficulty. Smaller than that ended up breaking the tile. Angled cuts were easy too. I didn't break a single tile, other than the 15mm strip. Things are looking up.

 

[Dan]

Hats off to you for taking on the task PJ. Not many DIYers would.

This will be a good before/after thread when it's completed. 😀

 

[PJPro]

Thanks Dan. Lets hope I end up with a good job!

The foreman has strongly recommended that I put (dry) underfloor heating under the tiles in the bathroom. My wife has been hassling me to do this to. I've always said that downstairs is the underfloor heating for upstairs. However, given the foreman's comments, I'm considering putting something in.

I've spoken with the spark who says he'll still be able to supply the necessary feed and fit the thermostat, etc. His company doesn't supply the matting but he's recommended warmup. I have to ring him tomorrow if I want to go ahead with the installation. Is there anything I need to be considering? I looked at the forum member's video blog (Gary?) and the tiling disaster partly due to the underfloor heating being put on high too soon so I've taken that on board.

The first coat of ADP primer is on the walls and I'm waiting for it to dry before applying the second coat.

 

[PJPro]

Well, the second coat of ADP is on and I've used the BAL Shower Kit to waterproof the vicinity of the shower. All the plasterboard joints have been taped.....and I'm finishing a lot later than I would have liked.

Oh, I also bought some mosaic tiles today. Small travertine rectangles on a mesh. They were reduced from £8 a sheet to £3.99. I'll cut them into rows of three and use them as a detail to break up the large format tiles. I think I'll go for somewhere around eye level.
