Placco for tall walls

[Gyn_Paul]

Calling on the vast repository of knowlege and experience of other Bricoleurs...

What does everyone find is the easiest way to extend placco rails for a wall which is higher than 2400mm ?

Do you just slot another piece of vertical rail into the top of the

first one, snipping a bit off the wrap-around edges to make it fit, or

do you screw a top horizontal rail on and then another 'bottom' rail on

top of that, and then more side pieces? (This is largely diagonal loft

work, so none of the extension pieces is wide enough to need a centre

support)

Either way it looks like a pain in the goal (fr).  I would have

framed it in wood but had the metal rail lying around looking

reproachfully at me; wish I hadn't started now !

We fitted a horizontal top rail, then onto that a horizontal bottom rail + verticals. Hasn't fallen down yet.

Don't know what I'm allowed to post any more (so I hope this wont get me banned).

You can get montants up to 3m long. Plasterboard 3m as well. It's heavy (the 3m plasterboard that is) but I managed to make a room from the stuff. I would not like to be joining montants as they are bendy enough already. When I did a load recently I doubled-up the montants (back to backed them) to help make the wall a bit more ridgid.

Much better to do this (provided it is high enough) as all the plasterboard I've seen does not have tapered ends (just sides), this they don't fill well and you will probably end-up with a line showing (or a small crack or something non-fatal but non-ideal).

I use 2 methods, the first is to use an 18" section of  rail R48 (what you use on the floor and ceiling) to overlap the butt joint between the montants, I then use my crimp tool (essential for placo in my mind) to rivet the assembly together.

The result is reasonably rigid but where it is an issue I do something similar to Deimos' method, I prepare two assemblies as above, fix them to each other back to back but with one butt joint near the top the other at the bottom.

I find 3m plasterboard too difficult to source and manouevre (and to expensive) so just accept the extra horizontal joints.

I agree with you, J.R., about how essential a crimp tool is: I've

turned the air black and blue while trying to screw the V's to the H's

with 1) just a black placo screw; 2) starter hole punched into the V;

3) pre-drilled pilot hole' 4)  all the above with a wooden backing

block

I was moaning about how vile the stuff was to a friend who lent me his

crimping tool (just to shut me up probably); Such Bliss !!

That and the clutch-thingy that stops you driving the screw into the

plasterboard too far are the two vital things you need to do any placo

work, I reckon.
