Working on a paint job on my Formica counter top (primer, granite spray
paint, and polyurethane finish). This is the first time I've used
Polyurethane and I'm getting different directions from different sources.
My question for anyone who would know:
Do I need to sand between coats of Poly?
I'm going for 4-6 coats, have the first coat on and dry, and am not sure if
I should sand or not. The directions on the can say "recoat in 6 hours. If
first coat is allowed to dry 48 hours, sanding is necessary between coats."
Does this mean if I don't wait 48 hours that I do not need to sand?
Thanks in advance for any help.
