Painting the Vacuum Pump

(Revised 10/29/15)

AP1

Painting the pump does not take very long and the pump looks great afterwards.

AP2

But preparing the parts for painting can take some time depending on how much work needs to be done.

A degreaser like Pine Sol should help remove the oil, you may also need sandpaper

AP3

All the parts you do not want painted need to be removed. For example, the rubber feet on the base of the pump.

AP5

There may also be portions of a part that you do not want to paint and those parts should be covered with masking tape.

AP6

There may also be portions of a part that you do not want to paint and those parts should be covered with masking tape.

AP7

Once the parts are clean and the parts you do not want painted removed and the portions of parts you do not want painted masked you can choose a paint.

I chose a spray paint from Wal Mart, it gives very good coverage in 1-2 coats and it takes about 24 hours for each coat to dry.

AP8 & AP9

Apply the paint in light coats using a back and forth motion in warm temperatures.

I did have a problem with overspray because I did not cover the area around the part well enough.

AP10 & AP11

Apply the paint in light coats using a back and forth motion in warm temperatures.
