Curved chimney breast

[FreeD]

How to you render the curve? I tried beading it, was a nightmare, I'm thinking of fixing hardboard underneath?

 

[mark ross]

Put about 10 or so evenly spaced cuts in the bead and jently ease it into the shape

 

[FreeD]

Yea I tried that m8, do you fix with muc? or screws and washers?

[mark ross]

If you have cut the bead on one edge it will give to a degree, especially a shallow curve like that. mark a level line each side then dab it up, as you have the sides.

 

[FreeD]

Thanks Mark, would you normally bead the head first with these?

 

[mark ross]

No, because until I put the sides in level 1st, I would not know how far out / or in the head would be. If you get what I mean.

 

[DannyMac]

Dosen't matter what order you do it in.

 

[mark ross]

Bit like beading a window, sides first always

 

[DannyMac]

How do you measure the extra length on the head bead created by the arc Mark?

 

[FreeD]

Thanks Mark, I'll give it another go, hadn't seen the job until today, i've freehanded these before but builder wanted it bang on, he showed me one downstairs and said I want it like that and I thought f**k lol

One last thing what did you mean by this?

'mark a level line each side then dab it up, as you have the sides'

Cheers

 

[FreeD]

mark a level line on the beads?

 

[DannyMac]

He means place your level across the aperture and mark each side where it meets the uprights

 

[flynnyman]

Before you skim it get yourself a skim bead the mesh ones and it will bend to this shape easily.

 

[mark ross]

He means place your level across the aperture and mark each side where it meets the uprights

Thats it, also, if you have shapped your head first to fit across the aperture, then bead sides, offer the shapped head to the uprights upside down ( mirror of right way on), mark with pencil where they meet the uprights and cut. Shoud fit nicely then.

oh and make sure you plumb beads of the existing plaster.

 

[mark ross]

Freehand it , then get your queenie out.

Why not do it freehand easy enough to get that shape and skim with a external corner trowel or render it first then use a plastic arch bead but not if a wood burner is going in

 

[Gibbo]

What mark means is you make a springing line on your beads so the head curved one looks right

 

[DannyMac]

Freehand it , then get your queenie out.

By queenie do you mean a flowery frock?

 

[spread1970]

my auntie was called queenie.

i did one of these the other week but it was on the reveals of the chimney.(if you understand) all i did was as mark said cut evenly little triangles out of the wings and stuck it up with muck then just tacked a few clouts in to hold it till it set

For the backing coat I would either freehand it or use a 2" plastic strip that window-fitters use. Then use a mesh skim bead for the finish coat, probs about the only time I would use one of them beads cos generally they're shoit :RpS_thumbup:

No they are great for slightly obtuse angles. And there's no "O" in sh1t:RpS_biggrin:

 

[bubbles65]

I'll give you that one Danny...................isn't JJ slightly obtuse? :RpS_laugh:

 

[DannyMac]

Not sure, I don't know him but from what ive seen he's definitley a good spread! Really nice guy too.

why bead the reveals first? i cut the reveals to length then the head then hold the head and reveal up together and see whats what then nail on

 

[DannyMac]

why bead the reveals first?

Because it's hard to guess plumb on both sides, but equally as hard to guess is the extra length added by the arch on the top bead.

So on balance after weighing it all up, it's all guesswork unless you trial fit like you say, but who can be arsed to do that...not me.

I say put the top bead on too long, plumb the sides up, and snip the extra length off the top bead where the sides meet it....carefully.

If you freehanded it first, would a 3mm stop not flex enough to fit?

 

[spread1970]

for the best curve would a profile under the head not be better?

soz mate i was on about on a window not the fireplace

 

[NPS]

why not just use a plastic render bead?

i use alsort of different methods it always depends on the time, arch, mess and so on

This forum is the most amazing place for hearing how to make a simple task sound like brain surgery.

 

[Jace]

snip the wing muck it in and tack a few nails in it for a while till its set up a bit simples
