all purpose plaster/filler any good?

[bludger]

Hello,

The last time I rewired one of my rooms I filled the cable channelling with one-coat plaster. I remember being dissatisified with it, but can't remember why.....

I'm now doing another room and this is a bigger job. Besides the cable channelling there are considerable gaps back to the cinderblocks where I've take away a cut-in extended stone fireplace surround. There's an area of mortar render which will have to be skimmed over, too.

My question is: is there any one plaster or filler which would do a good job on all the gaps, big and smalll? And on the skimming? If not, what two should I use?

Thanks in advance.

use one coat , if the chanels are deep then build up in layers , as when you do it all in one its packed but cracks when drying ...
hope this helps

I have used one coat. It is fine for amateur plasterers.

Hello Guys,

Thanks for your replies. I remember now I filled all the channels in one go last time. I'll use one-coat again and take it steadier. I appreciate your willingness to help.

Best wishes,

Just one tip bludger, do not get the mixture to wet or it is inclined to slump

I find, when filling chases, I'm happy with the result if I fill in near to the level, but a bit below, let it go stiff, then add a thinnish layer as smooth and flush as I can, and when that's gone stiff, scrape up with a filling knife to remove any overfill (I've seen people trying to level it with sandpaper after its gone fully hard )

Must admit I usually use Sirapite or whatever's to hand.

Hello All,

It's surprising how much info comes out of a simple question, isn't it? I like the tips that have come forth here.

I must remember to make sure the electricity is off if I thoroughly soak the cable chases!

Is it worth using a 5 to 1 mix of pva adhesive on the metal protective sheathing first? This ought to ensure good adhesion.
