Old hotel, render removed, approx 360m2, red grit applied to old, very porous stone walls, plasterers sand from Bradford’s is too gritty, mixing half soft and half sharp sand with hydrated lime and cement, in 3 sand, 1 lime, 1 cement mix, gear is nice to lay on, rule off, float and sponge, not too soft, not too gritty, sponges up and looks spot on, after a couple of days small cracks are appearing.
Could it be the use of the soft sand even though it’s mixed equally with the sharp? Any other suggestions would be appreciated, cheers.
