Plastering sand, Bulk Bag

Bought 2 bags, both had black stone mixed in with the sand (a lot of it about an inch diameter, and a lot of it pea shingle size). Save your sanity and buy from somewhere else

No I Know that we have been in lockdown for some time and just coming out of it but there's no need to let the quality of your products drop Plastering sand is ment to be pure sand and now there's small stones all the way through it no good for plastering...

This is more like builders sand than plastering sand, is it possible to get it without stone or supplied with a micron sieve?

I've used this sand with NHL 3.5 for bricklaying & pointing over the past couple of years, and have also used it for some exterior render (OPC:Sand 1:6), no problems with any jobs so far (no issues with cracking / shrinkage etc.). Provided you're laying a bed of render (or repointing) that's ~3mm depth, you'll be fine with this grade - granted, you'll struggle to feather it out without needing to brush out the courser aggregate.

This is meant to be for plastering, the only way I can see it being usable if you were applying 5-10mm thickness at a time. The bags either have inch wide pieces of black stone or the stones have been ground down to small stones which drag through the mix as you try to smooth it over. I spent ages with a stick flicking them out of the render I'd mixed which doubled my time doing the job. Never again!
