Cornice

[flynnyman]

@mikeadams1985 on a Job at the minute he has this I suspect it was run in situ coz of the deep bit in the middle. I am replacing with the same is it possible to run this style on a bench or would it have to be run in situ again? Cheers

 

[mikeadams1985]

You can run in a bench. You will just have to remove a section of the ceiling where the 'cove' will be deep.

I am going to drop an mf ceiling in below the existing cornice so if I left a section of the ceiling out and also a section of the wall out that would be sound? Also do you have that perticular style running mould to make one?

 

[superspread]

Make a mould and cast out is the easiest way and less messy ,becareful as it might be undercut although you can get away with this by softening the cove part of the cornice no one would ever notice ,especially as your not matching in as such

 

[flynnyman]

I will bell you might be easier lol

with the ceiling being dropped, and the cost to run in situ, its far quicker cheaper and less mess do off site casts of the cornice and install that way.

Also if cost is an issue , as opposed to an exact replica a stock cornice close to the profile should be easy enough to find,
If an exact copy is required then what mike said makes sense

John, drawn this up from the picture you sent, if you want to have a double check, you an see the alteration ive made to the cove part so it sits below the ceiling, as the two are not joining each other it wont be ever noticeable.

 

[mikeadams1985]

Ok, no idea why that was so small here it is again

 

[mikeadams1985]

And a 3rd attempt|!

Nice one mate looks good but I think a part is slightly wrong I think it should be a Cyma reversa or Cyma recta lol I'm sure you will correct me

 

[mikeadams1985]

thought that was a bit iffy when i drew it, will re do that. nice one mate.

 

[mikeadams1985]

Making a reverse mould, then casting from that. Bringing casts to site and fitting.
Wont need a loose piece mould, should just about come off, theres a bit of flexibility in the cast before its fully set.

 

[mikeadams1985]

Nah, that will come off fine, It may be a little tight but will come off. Good polish of the mould shall sort that.

 

[mikeadams1985]

John - redraw that, dimensions are the same, just altered that one section

this ok with you? Ill also PM you with confirmation of all the details and stuff

Looks spot on

 

[topstrop1]

Ryan is spot on . A loose piece reverse mould and cast it. Well done lad at least you have given the proper answer.

it wont need a loose piece. Guarantee it wont need one. Im hopefully going run it tomorrow and do a couple of casts so will post a vid of it popping of

Lift ceiling side of first, then it will pop out. :RpS_thumbsup:

 

[mikeadams1985]

Will be running it either tomorrow or friday.
Did a cast today that was even more undercut! and it came off

A lose piece is the right way, but with experience you will be able to look at profiles and just go 'that will come off' / 'No chance'

 

[mikeadams1985]

Hi ryan, the mould is a plaster mould. So probably wont come of the bench in once piece, One its complete, i will cut it in half (5ft) and put it in the van, if i can get it off the bench, your welcome to take it from there as its no use to me. (plus if something goes wrong on the job i can cast a new piece in the back of the van! haha)

 

[mikeadams1985]

Profile being cut





Core has been run and final profile on the mould ready for running




Ran it just before finishing work so will try and do some casts tomorrow and show you how it releases

 

[flynnyman]

Well mike came to this job the other day and battered it in no time, nice watching someone else work for a change also Ryan turned up to pick his brains which is what I was also doing. Picked up a few tips that will make my job a lot easier next time I'm fitting some cornice anyway here are a few pics.

 

[flynnyman]

Gonna get some more once it's painted the customer was over the moon and not very easy to please.

 

[flynnyman]

These pics aren't that great I'm sure mike has got some better

 

[flynnyman]

I learned a lot of tips from Mike and I have got guinea pig's old Victoria lodge to try - I run the mould and fix up - will send pics! Thanks to you great guys!

Guinea pigs lodge what's that?

 

[flynnyman]

I bet he agreed lol look forward to seeing the pics

I am trying to revive lovely fibrous cornices to go into pre 1919 houses in Grimbo as tired of boring gyproc covings where don't match the house character as I go fibrous as too much competition of cowboy solid plasterers.

its nice to see someone so keen !!! a lot of us SOLID PLASTERERS are also fibrous plasterers ryan!! back in the day we were just plasterers ( seems to be now solid, fibrous, floor layers, tackers , tape and jointers, renderers, skimmers, dot and dabbers!!!!!and it just goes on!!!) it is a pity that it has come of a bit of a separate trade, but again you are really keen to learn which a refreshing change well done mate stuy

 

[faithful]

Really interesting thread.......well done

 

[mikeadams1985]

Yeah was all one trade at one point. That's why so many jack in the box plasterers are popping up!


Btw that cornice looks amazing. Must have been a pro who fitted it. Sure I seen a pic of flynnyman fitting it???

[mikeadams1985]

No wasn't having ago at u Ryan. Just mean now since plastering is split like mentioned before its quicker to become a plasterer as u only have the solid side so to speak.
