Hi,
Would somebody please be able to provide some guidelines as to the grit sizes to use for various stages of painting.
Stage 1 - Bare wood stripped of paint with heat gun and sanded with 120 grit, next step is to prime with aluminium wood primer. Do I need to sand with a finer grit such as 180 before priming?
Stage 2 - Primed wood to be undercoated. Is 180 grit OK for a light sand of the primed coat or should I go finer to 240 grit?
Stage 3a - Undercoated ready for gloss. Is 180 grit OK for a light sand or should I go finer to 240 grit
Stage 3b - Old gloss paint, not removed but sanded with 120 grit to take off the gloss effect and provide a key. Do I need to sand with a finer grit such as 180 or 240 or is 120 OK?
