Hi. I plan to use this as my chance to occasionally share my views on the painting business. This is written for customers, do it yourself homeowners, and customers.
So this has been a miserable April. unless you're a duck Cold weather plus rain. An exterior painter's nighhtmare. To be safe you need the temperature to remain above 40 degrees over night when painting outside. And you definitely need a dry surface. I find that many customers are under the (mistaken) belief that a strong power washing is the right way to start any exterior job. Not so fast. A common mistake is to blast your way to poor results. Angle, PSI (pounds per square inch), and area being painted should all be carefully considered before launching into power spray mode.
I'm the first to admit that power washing is fun, but remember that water trapped under a paint job is a ticket to a paint job that won't last. If you must power wash plan on letting cedar siding dry for at least a week. A deck should dry for 3 days assuming it gets sun. A better idea (more work, hence often skipped in favor of power washing) is to clean the surfaces with TSP (Tri sodium phosphate) and a good mildewcide/moldicide. In these parts it's common to find mold growing on the north side of structures.
Well my kids are getting a little loud downstairs so I'll be back when I have a minute.
