Got the first coat onto three walls of the inside of the shed over the last few days:
The last few sessions I’ve been doing 4 or 5 mixer loads, rather than 8-9, and that seems to be keeping the worst of the lime burns at bay – not sure whether I get careless as I get tired, or if it’s just a gradual buildup of lime over time.
One change I did make was to tweak the order of mixing each batch to put more water in earlier. This seems to do a good job of keeping the mix mobile instead of clumping up on the bottom of the mixer, which means I don’t spend so much time poking around in the mixer, which means less render getting on my arm and clothes.
