Technical help - final layer of plaster

[Chrissofsweden]

Now I'm going to apply the last layer of plaster that binds the old and the new together. The surface is fairly even but not smooth.

1. Spray water
2. Throw on plaster
3. Smooth out with the trowel

That's about as much as I know. Anything special I should think about?

It is the 3an that is difficult if you don't know. Not too early so it goes with it and not too late so it's too dry.

If we talk about minutes between thumb and forefinger? The layer will be about 5-10mm.

It completely depends on how the surface absorbs. And if it absorbs evenly across the entire area, it looks like you have different mortar there.

Well, it's old from the 60s on top and new underneath. It is what it is. Freshly polished, half burnt

Damn, what a shitty job/craft this was It was very difficult to say the least, to put it mildly.
