25mm PVC Channel

[pauldreed]

I'm using lengths of 25mm PVC channel to bury some cables in plaster/breeze, but despite trying several nail sizes, the channel keeps splitting & cracking when I secure it.
What nails are recommended to avoid this please.

I only have one question. Why?

 

[Richard Burns]

Yes they do crack, if the capping is warmer it is easier to get the nail through without cracking, alternatively use a capping nail just to the side of the capping so the washer holds the capping in place.

Thanks Richard, looks like a good solution.

You could use platerboard nails, as the capping nails tend to bend or ping out sometimes but richards alternative is a good solution

Clout nails, it's like they were made to be used on the edge of capping

T+E clips work just as well seen as it's getting plastered over.

 

[swparksey]

I just don't bother, it offers little or no additional protection anyway.
Just clip direct and plaster over.

That's a pretty risky strategy.....only takes one slice with the plastering trowel and it's game over. In fact, most spreads I know would ask for capping to be put on first.

T+E clips to hold the capping...

I know it's late but come one, get with the programme... :lol:

Alright, alright. I'm still trying to get my head clear after Cheryl. Though in fairness, not so sure about our friends post in #8

True but I have found it depends on the width of the channel. I myself have dabbled in the dark and mysterious art called plastering and haven't managed to scrape a cable yet, just depends how you hold your tool... :lol:

I'd use clout nails as well.
Capping nails were the worst invention ever.

 

[jase]

whatever you use, dont go through the capping, go to the side of it, is why clout nails are good cos they have a nice wide head on em

Ah - so we're assuming that it's cable in a channel, rather than on a blank wall??? See, makes a difference, doesn't it.

For the record, clout nails everytime but I've also got a favourite trick for where you've got 2 or 3 cables on a short length of just a few inches and the channel is fairly narrow, try using a big penny washer (or 'repair' washer as they now seem to be called) across them and put the nail inbetween the cables. Works a treat.
