After painting the ceiling, work from the top down: Start with the crown molding, then do the walls and then paint the casement molding around the windows and doors. Do baseboard molding last. "Painting the baseboards last keeps dust and grit from traveling off the floor, onto the brush and then up onto the freshly painted casements," explains Weeks.
Most of us can do an okay job of painting a room. But a seasoned professional does a great job. Obviously, pros have more experience than the average homeowner, but they also know techniques and tricks that make them better painters. We asked six pro painters to share those secrets. They probably kept a few tips to themselves, but they provided us with more than enough to help you work more efficiently and get better results. Some of what you'll read may surprise you. For instance, their secrets won't cut painting time. Painters spend two to four days on an average-size room. That's how long it takes to prep, prime and paint correctly. It's more work, but when you stand back to admire the results, you'll agree it's time well spent.
This article is outdated. Deep based colors were an increase in price back in the 90's. Most stores have a standard price for all colors now. The problems the author are citing are outdated and rarely happen. This is the 2nd time I've seen this article being emailed out, it's irresponsible of angies list to keep sending out this poorly written and inaccurate article.
Back to the article. You can add water to all latex based paints / thinner to oil based paint. The tinting base has absolutely nothing to do with it. Say you are working outside and throughout the day you have to add a little water to keep the same consistency. If somebody really tried to add 20% to 50% water they no longer would be painting they'd be performing a whitewash or pickle finish.
