+1 any old plaster rather than filler.

I have had problems paining, i.e. bubbling. I try the recommended mist coat, but I don't know what I'm doing, I'm not sure that it always works. So sometimes I spray stain blocker coat on.

As I mentuioned upthread, it seems to have a half-decent OS and access to apps like iPlayer.

This is probably the best chase plastering video you will find

He does explain making a deep fill with easy fill and the beauty of this method is if you do not get it smooth with your trowel or scraper you can always sand it smooth as it sands very well once set.

Thanks, that's very handy. Bookmarked.

Oh dear, I may need to spend some quality time watching that channel :-)

But doing it before you have to decorate :)

I would also advise sealing all surfaces of a chase with some 50:50 pva:water and letting that dry before filling. Any brickwork, old plaster or edges of cut plasterboard can/will suck the moisture out of a filler if not sealed. Sealing will help avoid any cracking as the filler dries or cures. If you do find that the fill is still cracking lightly dampen down future fills using a spray bottle and water a few minutes before filling.

I find it better not to overfill too much but I tend to fill twice. Bulk filling first to flush and once cured/dried lightly sand and fill again. Despite claims about no shrinkage I've found fillers/ plasters do shrink and a second top coat just fills in minor gaps.

For small jobs like a filled chases hand sanding (if required) produces less airbourne dust than machine sanding. I use a GOOD quality 180 grit sanding block for light sanding of filler.

I've found Easy Fill 60 (60 minute) a good product. Be aware it takes more water in the mix than you may first think. It a bit like some tiling grouts in that the power seems to be a tiny bit waterproof at first :) Take time to mix it thoroughly, leave it a few minutes and mix it again - adding a little more water if required.

The product has a shelf life - which is the same with most plasters but I've managed to keep some and used it successfully after around 3 years and it behaved the same way (drying/curing) as when used originally. I filled some empty Douwe Egberts coffee jars which come with airtight glass lids with a plastic seal. I filled the jars to the very top and then tapped them on the floor to vibrate all the air out of the power, filled the new void, repeated again and jammed on the lids.

He does explain things well, however he does make things look easy which comes of many years in te trade.

For drywall/plasterboard fitting and/or filling of joint and patches, without plaster skimming, try the Vancouver Carpenter Youtube channel.

Thing I didn't appreciate was how well modern pigments keep their colour and how touching up a wall with the same paint was pretty much invisible
