I signed up to your online plastering lessons to learn more about plastering (i'm still new at doing it).
I'm running in to a routine problem of getting the plaster flat, soon
as the first coat goes on I'm evening it out, but when it's dried I can see where it isn't flat.
Have you got any tips on how to avoid the issue?
Doing these may help:
Ensure the plaster you're applying is runny and not mixed too thickly.
Ensure the depth is no more than 1-2mm
Use as big/long trowel strokes as possible.
Push really firmly (ensure correct trowel angle)
Don't play around with it - make sure it is as firm as it should be to get the desired results in each relevant stage
Hope these may help
