WHAT DOES SPEED UP PAINT DRYING AND CURING MEAN?

How long should in hold out in between expenditures for painting trim? Waited 24 hrs soon after initial coat, paint was dry so I used 2nd coat. Am i able to apply third coat just after 24 hrs or must I wait longer? I do think it needs 3 coats of paint.Closing Touches: After the final coat totally dries, inspect for virtually any uneven spots. Conta
