Small random-orbit or pad sanders make this job go faster. (Wallis first covers these boundaries with Synkoloid patching compound so no edge is visible after sanding.) As shown, you want to make sure that there is a feathered, smooth transition from exposed wood to old paint. For areas that might get close scrutiny, you can follow up with a 100- or 120-grit rubdown to erase any scratches.
Yet another 5 star for them. They already have a perfect 5 stars with 246 reviews at the time of this writing--I feel like they're hoarding all the 5 stars... Anyway, they deserve it. I interviewed a number of different painters, and they were the most responsive and professional. Their rates were competitive too. So, I went with them. I had paint done inside and outside my house. Some of it was rather tricky--the outside is on a hill, and the inside has some funky artsy stuff going on that I had them do. The people doing the painting were very professional, and did a very detailed job of prep work before the actual painting, which is something this detailed-eye notices. The final result was impressive.
The best time of the year to paint your home is typically in late spring and early summer when it’s warm outside and moisture is low. This can change based on your geographic location. For example, fall can be a good time to paint in California when the difference between high and low temperatures is low. Your painter will select the optimal time to start your exterior painting project.
