I did 2 coats of the mix on the inside of my tongue box on a thursday i think. On the saterday i did one more coat inside it and then about 5 coats back to back on the outside of it and the lid.
When the mix dried on the inside saterday it left white chalky powder everywhere.
Tuesday i did a second coat on the outside and as it dried i got white powder everywhere.
Is it bad? Am i doing something wrong? Or is it normal?
