Great vid! Potassium bitartrate (cream of tartar) is used in some commercial gypsum plaster retarders. It’s even listed as an appropriate retarder in some plaster manufacturers’ literature. Works like most acids for slowing the set- citric acid and vinegar are two other household chemicals that work similarly. A saturated solution of borax works really well though. You can add it to your mix water in any proportion you want to precisely delay the set time. Anything from one part solution to twelve parts of water (~15 minute delay) to one part solution to one part water (12 hour delay). Most retarders won’t effect strength in any way so long as your plaster doesn’t dry out before curing. Another class of retarders that work in another way include gelatin, hide glue, some plant products, etc- many of these types of retarders will increase the strength of the plaster 👍

Also, in another great video you guide through the stages (which trowel and plastering step when)... Please make a video how to identify those stages and what to look for. Your guidance is supremely valuable. I have to plaster a home and just go semi-blindly, but there is no way I can afford a professional.

I used to use it while running in situ cornices in lime and plaster of Paris, the cream of tartar extended the normally very quick set of the gypsum by about three times. I noticed that the longer it took to set the harder the plaster became. I had one job that I overdosed that took 3 days to harden

Hello fantastic video. My comment isn’t about this though. I’m wondering how your getting on with the Venetian plaster work. I’m wondering if it would be worth while adding to my arsenal.

i would love to see a video where you repair a wall, i saw the one with the mesh, but that was for an exterior and in a small area such as a bathroom, every mm reduces the amount of space after you do your waterproofing membrane, tile adhesive and thick tiles. How would you repair the cement render in a shower after you remove old ceramic tiles and it takes chunks of the render off with it exposing the brick, can i just fill in where the chunks come off and prep the wall with SBR and cement slurry?

Off topic but do you pros take rads off the wall to skim behind? I'm a DIYer and will start tackling my house soon. I'm not sure skimming around rads feels right but taking them off seems like a faff if not necessary... And feedback is welcome!

because this is what british people been taught using 100 years ago and they don't like changes and upgrades that's why you'll only see one type of plaster and everyone only using trowel. They didn't even hear about roll on plasters

The gypsum in the uk quarry where it’s been taking from is that colour. Skim coat in Ireland is grey and drys out pure white. Carlite finish in Northern Ireland comes in grey or that brown colour. Depends what quarry it’s taken from.
@dannyboy98176 ай бұрын
Thistle Bonding in the UK is sometimes pink and sometimes grey. The pink stuff is made from natural quarried gypsum. The grey stuff is made from desulphogypsum (bi product of flue gas desulphurisation process in coal fired power stations). I personally find the grey stuff less sticky and a bit more gritty than the natural stuff and I'm always slightly relieved when I open the bag and find it to be pink, with the reassuring aroma of cat wee (🐈🐱).
