I'm using Ty Mawr, ready-mixed, fine-grade hemp plaster to do a base coat on an area of an interior brick and stone wall. Hopefully this picture links works ...View media item 97840
It's filling in area surrounded by good sound plaster (regular not lime) and going onto brick and stone. I applied it on a damp surface and I've sprayed it daily.
BUT after about a 1 week, it pulled away all around the edges and a crack of about 2mm has opened up when new meets old (as highlighted on the photo - but you can't really see it).
So what do I do? It's still a little bit flexible to the touch: do I add new plaster to the crack and push it in? Or leave it? Or try to push in the week-old plaster and hope it makes a new edge?
Lime plasterers - please help!!
Thanks
