Hello,
I'm trying to match ten foot square area 1940 interior plaster sand float finish. From what I have heard, plasterers used to mix the aggregated basecoat 1:1 with gyp and apply that as finish coat and float it. Because of materials that are avIlable, I am using 1/2 structolite and 1/2 imperial veneer finish ( in USA) floated with fine green sponge float.
I can get the texture pretty close, but sponge
leaves light lines or trails in plaster from aggregate pulled or dragged down from sponge. Original plasterers work shows no trails at all, just a light texture of sand or perlite. What am I missing? Did those old timers also use a sponge, or did they use some sort of other float? Is my plaster mix ok u think? I am waiting to float until it's set up a bit, but always the same end result-- a sand float finish with lines that does not look smooth. Any ideas or help would be much appreciated.
