scrim and skim square edge. On tapered I scrim and fill the tapers out 1st.

I never use taper edge, it’s primarily designed for tape & fill which I will never do. Use square edge boards when skimming, taper edge just creates more work as you will have to fill out first.

Butt boards close (12.5mm) & apply reinforced fibre mesh scrim tape over the joints; float over the tape working plaster it well into the mash & rough fill the screw heads as you go.

rich on sq edge do you bother doing the joints first just before first coat or just as you go..and then second coat.
so just scrim, then two coats?

i never fill the taper in first and i find that you get a better result with taper as it covers the scrim better

so you just scrim up TE and skim..do you ever find the joints a bit sunken

Where I am we can't get square edged boards so I only use Taper edged boards, I put a coat on then the scrim, then bring it out to the board I usually do all the joints like this and skim when the joints have firmed up...Works for me If I am dot and dabbing then I will scrim and tape all my joints and angles with the board adhesive then the next day run over the joints with a roller with pva then skim the lot..

no never and i used to skim a couple hundred m2 of it a week, if you had a job where the partitioner hadent done his job proper "ie" boards are not straight or joins are not level you would sometimes see the scrim grin through on butt edge boards, ive seen this on quite a few sites, but with taper edge the scrim is sunk back a couple of mm looks a lot better, and all you would see is the Silhouette of the taper as the board dries out but it would be completely level

ive dug out some pics on my pc to show u look at, the top in the first pic you can see where the tapers are and you can see in the pics that the skim is flat View media item 26239 View media item 26240

yes inside you are doing to much just tape and skim

For me, if its tapered or square I scrim the joints, skim over the scrim first then carry on as normal.

Steve, in those photos, why does the finish not go all the way to the top?

because the false ceiling will be going up, the site agent will tell you how high he wants the skim to go, in this case i think it was 100mm over the ceiling line, the 100mm will be enough to get the ceiling fixings on

I see, it makes sense now. Cheers.
