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.
Hello I been reading your blog. Filled with great information thank you. I have a question. I have been doing projects for these people for some time. I do a lot of carpentry and painting. They want me to do their interior painting. 1 problem they are planing on retiring and selling the home. It is in great shape, but the wife wanted to paint every room in the 2100 sq foot home. They got a price of $14,000 from 1 painter. I spoke to them and told them the paint and walls for the most part are in good shape and they will not get the money back when they sell for painting. I recommended doing what really needs to be done. I know why did I talk them out of a good money job , I am honest thats why. Problem is the base molding being 8′ with quarter round on a wood floor throughout and all the window casings, doors and door casings need painting. Plus a wall over fireplace a full bedroom ceiling walls closet.Bathroom wall entry from garage room. but all base molding on lower floor and half on upper floor needs to be prep sanded and painted. I will be using epoxy to fill some areas and 2 doors need to come off and work in garage due to large cracks. How do I price such a job that is so spaced out? Please help me I am lost for a price and need the work but don’t want to give it away. Thank you jim House Painting Broomfield Colorado
