3. Painting method
a. On wooden cabinets, paint can be applied with any method, brush, roller or spray. Metal cabinets look best when sprayed.
4. Painting the grills
a. Painting the grill is the most challenging part of refinishing a loudspeaker. Grills MUST be sprayed. Here are the steps necessary to
properly paint a grill.
i. Lightly sand or Scotch-Bright the grill to remove the gloss of the finish.
ii. Degrease the grill with mineral sprits or alcohol and allow to completely dry.
iii. Spray the grill at a low angle so the paint enters the holes in the grill.
iv. You will need to apply eight light coats of paint to the grill, four coats on the back, one from each direction; and four more on the
front, again, one from each direction.
v. If you don’t get the paint all the way into the holes in the grill, the grill will appear to change color as the observer moves off axis.
