With the significant amount of wall and ceiling area, I wasn’t looking forward to using a roller to paint the inside of the shop. I’ve used air-spray guns to apply lacquer to my woodworking projects so I
decided to try an airless paint sprayer. I was going to rent one for 3 days but my neighbour Barry said I could borrow his, so I took him up on the offer.
The paint store recommended a coat of latex primer followed by two coats of latex semi-gloss finish.
We calculated I needed 5 gallons of each and it came out nearly perfectly. I had to buy one extra gallon of primer but that was probably due to my still-learning technique and the bare drywall in the primer phase.
I used TSP to clean and de-glaze the existing painted walls, then went ahead, painting one coat each day for 3 consecutive days. What did I learn?
With the windows completely masked off and the fluorescent light fixtures removed, it was too dark to get good pictures of the process. Here is a picture before painting, and several views after the final
painting coat and cleanup:
