Spraying Baseboards on Wall
You don't normally go to this extreme painting baseboards but this custom built house on Eagle Mountain Homes in Abbotsford, BC, had so much trim in it that I completely masked the hardwood flooring off to spray the baseeboards and all the other trim at the same time.
Preparing for spaying like this was a ton of work but it produced silk smooth results and reduced at least 80 hours labour in comparison to traditional brush and roll.
Below is a picture of me taping off the boaseboards.
