I am painting some wood with Helmi primer having sanded the old paint flat. Some areas were thinner so you can see those patches. I have applied one coat and it has flattened nicely. I am not sure if I should add another coat of primer or go for two coats of Helmi 5 Matt? I really think more primer coats is best but would appreciate the views of more experienced users.
What would fellow Tikkurila users do?
