[@Onthetrowel]

Thanks Dean. Appreciate you mate 🙂👍

[@m.c.SHoppIng.cenTrE]

as a tiler, whenever someone says 'we have a plasterer coming in first to get the walls ready' i always shudder, 90% of the walls i'm given are nice and shiny and are never flat enough to even stick small tiles on, let alone these massive 900mm tiles that are popular at the moment, well done mate on highlighting the right way to straighten up wonky walls .. :) cheers bud

[@Lemon-squeezer]

That’s because the tight arse customers only want you to skim it they don’t want you dubbing out as it costs more and they all ways say its just for the tiles to go over

[@ksmith7611]

And you shouldn't tile onto skim neither

[@muhammada5178]

@@ksmith7611no mate you can. You can’t tile onto bonding or hard wall. You’re just limited to 20kg/sqm weight with plastered walls which is pointless is walls are boarded well, as the plasterboard holds 32kg/sqm before the skim!

[@m.c.SHoppIng.cenTrE]

@@muhammada5178 in 25 years of removing tiles i've found that tiles on bonding is better than skim, although removing them will take the bonding off the wall with it if sealed correctly, often back to the brickwork. but i agree that plasterboard is the best for large format & porcelain tiles , unfortunately Tile shops are selling tiles to the public that are unsuitable for average housebuilds in the U.K.

[@m.c.SHoppIng.cenTrE]

@@Lemon-squeezer this is why many customers either get a massive shock when theyre told the walls are unsuitable and require levelling again, or end up with a really crap tiling job. next time a customer says that to you, explain how important it is to get a nice finish from the tiler, it will save them alot of heartache in the end.

[@rumar4u]

Here in Latin America during phase 1 (prep day) and depending on how big the wall is, master plasters make 2 guiders with plaster (around 2 inches wide) and use a level on both of them, making sure is perfectly straight from top to bottom. Next day when they plaster the whole wall, the aluminum scratches perfectly using the dried plaster from previous day as base guiders. Works great

[@AdamCiernicki]

Most of the plastering I’ve seen in England would result in nonpayment in places like Poland or Germany. After plastering is done they come with massive 2m+ level, push it against the wall and shine bright light on one side. Building standard demands the wall to be flat across that distance. We use rough plaster under coat that goes on the brickwork, only then actual plasterer comes in and does the final coat using finishing white plaster that’s NOT cement based. It’s softer allowing for the wall to be sanded down, then primed giving you the above mentioned flatness.

[@johnsmart4692]

[@Dutchy8ball]

Respect there mate as a Plasterer for 40 years bathrooms are the worst jobs of all I’d say, no room to swing a cat, bathroom installers and tilers all think you can plaster them in a few hours and work you do doesn’t get seen at the end of the job as it’s all behind the tiles, well done good vid 👍🏻

[@m.c.SHoppIng.cenTrE]

i know, us Tilers get most of the praise on completion, but i always appreciate the chaps who prep the room , it's the most important of the process, except maube the Plumber, LOL

[@stevelopez372]

Plasterers prepping walls for Tile. Never heard of it in California. Old tilers took care of prepping their own walls. The Building Code allows up to a 1/4 variation in 4-5 ft. Straight edge for exterior plastered walls. No good for tilers. However in UK or other countries it’s interesting that plasterers would do that prep and understand what’s necessary for tile work.

[@chrismulhearn7903]

Agree wholeheartedly. I can attest from experience as a tiler, plasterer responsible for everything from design, to demolition, making good and true through to tiling, grouting and siliconing, whilst traversing every error made by plumbers and electricians along the way.

[@162tsb7]

A vital aspect of plastering that is all but forgotten or ignored. Dot and dab generation have never been taught this skill. My 1mtr and 2mtr feather edge's are 2 of my most important pieces of equipment. Well done mate keep up the good work.

[@Mateus-sz4je]

👍Sometimes i'd dab/level up 3" wide strips of plasterboard floor to ceiling in 1mtr bays, float up bays in no time using the strips as guide for straight edge then pop them out and fill in.

Nice work pal, I also prefer sand & cement

[@TRMNNYC]

Some years ago, I began learning three coat plaster in the wake of a disaster involving joint compound on old plaster walls. Entire first floor of a house and an orbital sander with a serious grit to reverse the mistake. It hurt. Finding no one in the NY metro area to at least give me pointers, I embarked on my own trial and error program-do I really have to say mostly error?! Recently, I decided to attempt a screeding concept using metal corner beads. Yeah, kinda pathetic. But how to achieve those elusive flat walls that I just could never get? Well, I own a feather board and a Darby, but I was uncertain just how to use either? This video has provided the next steps of my learning process that would have taken a lot more time without it. I really appreciate your instruction. Thank you so very much for your time and your effort.

[@daveblack9105]

Great video, thanks for making something so useful. I'm literally doing the same job on a bathroom that looks exactly the same!

[@marklundeberg7006]

Fun mathematical fact: if you darby a surface horizontally and darby it vertically over and over again, until straight both ways, it doesn't mean it is flat. Rather it can be a "bilinear surface" - look that up. So checking at odd angles may be important.

[@NiktheEnglishGreekCypriot]

Very true indeed. Same as an artex ceiling, flat but not remotely level

[@DMark-c3r]

I believe both you and @NiktheEnglishGreekCypriot are wrong. If your straight edge is long enough to go wall to wall, ceiling to floor, then your surface might not be plumb but will be straight and possibly flat.

[@marklundeberg7006]

@@DMark-c3r I really do mean it as a mathematical fact. A bilinear surface has the horizontals and verticals as all perfectly straight lines, yet the diagonals are curved. So if you darby a surface to perfection both horizontally and vertically, you can still end up with a curved surface. Not that this is necessarily a bad thing! If the four edges of the wall are not coplanar then the wall cannot be a plane. The curving may be imperceptible and practically necessary.

[@DMark-c3r]

@@marklundeberg7006 I know you do. But just for a second try imagining a straight edge moving from the floor up to the ceiling without you ever seeing any gap between the edge and the plaster surface, and then do the same thing while moving it from left to right....and tell me what you see? Flat surface or you still see some curvature in the corners? If you have problem imagining it, just put a piece of paper on the table and move a ruler across the paper, up and down, left to right...no gap, right? Now move the paper to the table edge and let it hang in one corner (to simulate your "curve") and move the ruler. When you pass over that "hanging" corner you will see a gap between paper and the ruler. That gap is not there when a whole piece of paper is flat on the table.

This guy is young and strong as an Ox most of us couldn't pull this off, I would like to see him get these walls ready for painting, that would be next level.

[@mickygism]

The whole point of keying a wall was to provide a mechanical key for skim coat, if you look closely at bonding you will see tiny pockets and holes for skimming to grab onto . This is what the old timers fail to understand, it has its own key

[@petemoring67]

Regarding the Devil-Float? .... Your Dad is Right! ... Most! Plasterers think it's all about KEY! ... It's NOT! .... Thistle/Siraphite/Statite would ALWAYS stick to Sand & Cement Render whether 'keyed' or not! ... The purpose of the Devil-Float is primarily to get the surface 'Flat & Closed' ... Rather like using a 'Cross-Grain' as the No2 Float in a 3 x coat finish .... When you can lay a render wall on pretty flat anyway, you don't need a rule - Just a GOOD Devil-Float and it'll come out Perfect!! 👍🤠

[@poohpot4462]

Really liked this one Kirk. When is the vid with screeds coming out? Can't wait!

[@johnturrell942]

Great demonstration Kirk. You are a true skilled tradesman. However as its a bathroom I would have lined it out with insulated tile backer boards.

[@johnwarwick4105]

Funny I was thinking why bother with the skim coats if you are tiling it anyway, reading the comments some say that they won’t stick to bonding coat, can’t understand why as that tile adhesive sticks to most things 🤷‍♂️🤷‍♂️

[@muhammada5178]

Hi Kirk, as my brother who has taught me a lot about plastering. Since you’ve helped me become a better plasterer, as a bathroom specialist myself. I just thought I’d mention that you should have used Sand and Cement instead of the bonding and tiled straight onto that, this would have allowed you to put any tile onto the wall.. Whilst your method is also correct you are now limited to 20kg per sqm in tiles and adhesive and grout once you skim the walls this is again if tiling the walls meaning your safest bet is to use a ceramic wall tile and not porcelain as it would be too heavy. Regards Shiv. Hopefully this comment reaches you before you get to tiling. If you would like me to do it for you for free pls give me a message id be honoured to help you.

[@muhammada5178]

Also Kirk you will be ok regarding tile on plasterboard as it’s 32kg per kilo. It’s recommended to tank shower area also

[@whippetRalph]

Cheers, just ordered a Carly.

[@elliotcarter6907]

Kirk, can you do some solid wall plastering. Particularly internal exterior walls like window walls and how to combat them. Im facing an issue where i cant baton and foil back the board due to the style of window and unsure on rendering and skimming without stopping damp etc. Quite new to the game. It would be great to see. Your content is great. Elliot

[@yfelwulf]

I only plaster at home every few years just replaced some heaters watching you I realise I'm a far too harsh Critic of my work. I get frustrated at how long it takes me to get a good finish. Cheers me up when AC installers and the original fitter said I can't see any sign of the Hole I made and was there a heater here. Still hate plastering.

[@WombleUK]

Kirk you better have put a rip of plywood over that lintel where you dot & dabbed above that window? Because us Carpenters get asked to put some curtain poles/rails up & you blimming plasterers have just dot & dabbed & there is nothing there to get a decent fixing to. Now we got that bollocking out of the way, keep up the vids you do some great videos & very informative 😊

[@NiktheEnglishGreekCypriot]

It’s really not hard to fix onto plasterboard. Wall dog screws go straight into board, or you can screw through into the brick

[@WombleUK]

Good luck hanging curtain pole brackets on whirlie fixings into plaster board & there is no brickwork where the steel/lintel is. I been a Carpenter & Joiner for 37yrs so more than the familiar with the nothing to fix to above the window nonsense. We always do some solid blocking in steels where we think brackets might go but a solid rip of plywood/OSB just solves the problem completely & isn't hard to do at the time.

[@WolvesValleyFarm]

I have a question for you. I'm renovating an extremely old house that was built with brick and clay mortar. The joints were completely gone, it looked like the bricks where held up by air and sheer refusal to fall over alone. I've covered the walls with a metal mesh, then primed them with a watery sand-cement mix. I then put a vertical line of sand-cement on every meter or so which I leveled. (the was were significantly out of plum) Then filled up the space between with more sand-cement. In the first room I did I then wen't over with gypsum finishing plaster, and that turned out to be a major mistake. I put on 2 coats with a fibreglass mesh stuck in between but the result is shit. It looks absolutely terrible. What can I do to fix this and get my walls nice and smooth and level? Also, I''m puting on the sand-cement in the next room. What can I do to make sure I get it right the first time? Thanks for your great content. I subbed immediately!

[@162tsb7]

I feel your pain. Did a job in an old terrace house years back the walls knocked off to brick. The supporting wall between the front and back room was double brick no cavity. On one side it was 4 inch out at the top to nothing at the bottom vice verser on other side. It was solid even though 100 years old. We screwed roof lattes to it each side and middle packing them out so as plumb to use as rails for our feather edges left to dry remove lattes and fill. Then plaster. Sometimes you're faced with a pile of shite which cannot be polished, but you can sprinkle glitter on it mate. Keep going always a way.

Good one kirk . Is scratch coat cement ? If that was leveled can the tiles go straigh onto that , as i know tile cement is a really adhesive.

I simply don't have time to build experience but I DO like to understand the process...been subbed a good while now too ! 😎👍 One job I did do here was to rout out the old lime mortar between the stone using a cordless drill & a 1/2" masonry bit to almost 6" depth ( doing sections at a time so it didn't collapse in on me !! 😮) and re-pointing every single sq. inch of the inside of the exterior wall surfaces... the old stuff was virtually just sand, spilling out... 🙄 No DPC in the floors so I put a layer of 25mm rigid insulation down followed by poly followed by 22mm flooring ply and laminate flooring on top (vinyl laminate in the kitchen /bathroom) I would have liked more floor insulation but was limited by the internal doorway heights... Speaking of doorways, when re-pointing the walls over the doors, I found old tree branches used as lintels !! 😂 they crumbled when I just looked at them ! 😮... new concrete lintels were installed, heavy work on yer own .. 😤 I lowered every ceiling by a foot, dry-lined, plumbed and re-wired ... and filled it with rigid foil-backed insulation , 8" in the ceilings, 3" in the studded walls ( I built 3 x 2 studded internal walls stepped an inch away from the old stone external walls to allow for breathing up into the vented loft area) and 38mm insulated drywall over that for a 100% thermal break...

Hi. Is there a reason why you wouldn't put sand and cement on low suction backgrounds? As in applying SBR, let it dry and then S&C. Thank you.

[@Onthetrowel]

So bonding coat is light, sand and cement is fairly heavy. I'm not saying it wouldn't stay on if it was thin but I wouldn't like to guarantee it. Probably not worth taking the chance. It's the same with hardwall, it would probably be OK but we have a product that is specifically for it. Don't fancy taking any chances when my tiles have cost a small fortune 😂😂

[@andreyutzu9421]

@@Onthetrowel I think I understand by what you mean with low suction background. I've DIY my render on bare brick and blocks and applied SBR but did not let in fully go dry. I applied S&C on the fairly wet SBR so I could get a better adhesion. I've also done my render mix with water and 3 parts SBR. Hopefully nothing wrong with that and the render won't start falling. I also thought about the whole thing falling which is why I'm going to stick XPS boards on top of the render with adhesive in the bathroom and mechanically fix each board with multiple concrete screws.
