Masking a Perforated Area

Question:

I am looking for some advice on masking the far side of a perforated area. Whenever we do this, we get paint buildup in the perforated holes and have to brush it after removing the masking material. Is there a material that will absorb the powder/wet paint so it won't build up in the holes? J. F.

Answer:

I recommend that you discuss this problem with a masking supplier. One can be located in the PF Online web site (www.pfonline.com/suppliers.html). You are probably using tape that when removed leaves the powder coating inside the perforation hole. Try to use tapered plugs from the backside. Depending upon the size of your holes, these can mask one side of your part and still let some powder coat the inside of the holes. If you don’t want any powder in the holes, use hole plugs (not tapered). In any case, talking to a reputable masking supplier will ensure that you get the latest technology to solve your problem.
