Hi
I am a DIY plasterer rather than an expert. I've used both gypsum and Limelite and I find Limelite ok to use but you need to put the bonding on first or it doesn't stick to the walls very well.
However, I've plastered my house with Limelite Renovation plaster and top coat to treat damp issues after pulling off the old mix of Lime and gypsum plaster put on by an incompetent builder employed by the previous owner of my house. (which reacted badly due to salt issues).
Results are very good.
Limelite doesn't go off as quickly as conventional one coat Thistle plaster. Which for me was very good as I'm very slow at plastering. Which makes ceiling normally a nightmare with gypsum.
Major difference with Limelite is mixing. Start off with less water than normal and add slowly or you end up with really runny plaster. If you add too much Limelite too soon, it becomes to heavy to stick to the walls.
