phhhhhhhhhhhh.....don't listen to em mate dont get bogged down in all this joist talk....just screw em where ever yer fancy...youl be paid before they fail ish maybes sometimes!!!:RpS_thumbsup:

Haha it's for my mum so ill be getting paid in sarnies a reasonable dinner and possibly a few tinnies after :)
 
I know i normally ask for some cookies aswell ! Dont be letting every one know u dont need to buy the cookies ! So prices stop now !
 
Had an uber big artex ceiling to do and I decided to reinforce existing board as it'd been tacked up with nails n ice cream..

My method..

find the first joist on one side of room, this can be done anyway you like but as I was not over boarding i drilled down from loft as I didn't want to bash the lid..

put a plasterboard screw in the centre of the joist, at both ends.. Leave it 2 or 3 turns off flush.

You now have two screws in two corners of the room, marking the centre of the first joist in the run. Find the joist pitch ( as I had access to loft was easy), then hook your tape on each screw in turn and mark out the rest of the joist runs with a pencil.....

Put a a single screw in each joist position you marked with pencil, at both ends of room just as you'd done with the first joist. Start with the furthest away joist.....if it hits home the likelihood is the rest of them will hit home....if not shift left and right an inch and have fingers crossed! , remembering to leave them 2 or 3 turns off flush with board..

when all your joist ends are marked with a screw ( again not fully home), get a string line, start in one corner and link all the screws with the string in one hit, tighten the last screw down on your string line and your ceiling is strung out for screwing!

maybe overkill but on your own, and where you don't want to disturb the existing too much, if works a treat and surprisingly efficient and far easier to do than explain!

I expect the the same could be done for over boarding but I normally just get my old mans old brick hammer out and make a proper mess!
 
You prepared to go into dusty attic? Nah - lath hammer will do - won't make big mess - first wet the artex then strike a blow.....

customer had been warned of the 'lethal' asbestos hazard, I even had a sprayer on hand to damp down any dust whilst screwing the screws home.....!

As it went, a very accessible loft, not boarded so was a 60 second job to pop a 2mm drill bit through a ceiling and measure the joist pitch.

Best part, the customer was so impressed at the effort I went to and how professional it was . now doing his daughters house ....top to bottom.
 
Thank feck i gave up the overboarding game........to complicated:rolleyes)

joists,chalk lines, drills, lath hammers..:RpS_scared:.....=sore head:RpS_lol:ffs
 
I normally run a circular saw down each edge of the ceiling, when sawdust falls then i know I've hit a joist.

It's the fastest way.
 
Ok,so we decided against overboarding due to A, not being able to fit boards into my van and B, breaking the board I put into my van when checking it would fit by closing the door and C, is A and B not sufficient enough? So we scraped around the damaged bit then overskimmed and this was the finished product. First ceiling attempt remember.

As the wand says it's bits you've missed when troweling. You can tell by the way it's drying, run your fingers over it and if it feels rough you will prob see it once painted.
 
get it covered quicker , then get over it softer ,constantly looking at your work from all different angles, by the time its set you should have spotted all misses, looks like you have done a hard trowel, try finish(cross trowel) just before it changes colour ,all same way ends up uniformed, opposite ways equal striped finish ,good luck in your plight for perfection !!
we all strive for this, its what keeps your work good and upto a decent standard, it wont happen overnight so be patient :RpS_thumbup:
 
Ah ok,how can you see it from the pic? Trowel lines? ( sorry for the stupid questions )

This was a ceiling I done few weeks back with the new unifinish. As you can see it's all drying the same colour and I've checked at all angles for any hollows or missis.
 
Bits you've missed when trowelling up

Bits you've missed when trowelling up


George..


you will hear people say, 'just get it on the wall and trowel up'.....or the like.. , they're either very good, or very stupid if they say this, as they ain't got a clue how you lay on..... As the wand says, 'misses' is the word used when you've left a void in the finish as you're laying on, ie you have not filled it with multi or whatever..


However, heres the secret to fewer misses and an easier troweling up routine... All about laying on properly in the first place


one you've laid your first coat, flatten off.....you'll then notice the low spots.....or 'misses'. Obviously, this ain't a problem as you're gonna smash a second coat on...this is they key stage to ensure you don't leave any misses......


the second layin coat should not leave any missus, cus if there are, you then gotta fill em in on 1st trowel...or second if unlucky enough to miss at 1st.


The secret is, take your time on the second layin, butter coat or whatever you call it.....this will pay dividends for the rest of the set.....don't labour on it but.....don't rush it.


As a rule, I'd overlap the previous line ( spread gear) with my trowel by 2/3 inches( maybe more depending how much gear you carry on your trowel and how you load it), until you notice the join between the stripe you're laying and the previous is nothing more than a seem.....which is easy to flatten off at the 1st trowel.. If there looks like a void between the two, that's a miss....it'll take 5 seconds at this point to quickly run your trowel down this with a little gear ....thus filling the miss.


So, you shouldn't have any misses at all when you arrive at the troweling up stage.....sadly I can't always practice what I'm preaching!


As always, all down to experience......keep it up and a switch will click one day and you'll master it.


Have a look at these I took a long time ago, it's all a uniform colour because I've not needed to spread weak gear into misses or trowel off high spots.....secret is in the second layin......
