To apply small speckles, create a fine mist further away from the specimen. Quickly move the spray stream across the
specimen. If large paint drops are landing on the specimen, consider holding the specimen above the spray stream, as to
allow the larger drops to fall below. The specimen below is a 1” IC that was coated in this manner.
For larger fields, larger speckles must be produced. This can be accomplished by either modifying the spray nozzle or
throttling the spray. One effective technique is to place the surface horizontal and spray down onto in. If the spray nozzle is
barely pushed down, large blobs will come out and fall onto the surface.
The 48” panel below was painted this way.
NOTE: SPRAY PAINT TECHNIQUES ARE PRONE TO VERY FINE MIST ON THE SURFACE, WHICH CAN SOMETIMES CAUSE
ALIASING.
