Some of the window sills in the new condo have paint which is chipping or flaking. The worst one was just over the kitchen sink.
I used a putty knife to pry away loose paint, and tried sanding the result.
I decided to get more aggressive and remove all the paint, and applied some paint remover. I scraped this off 30 minutes later with mixed results. I ended up scraping it all off with a putty knife, a rather difficult and tedious job. Then I sanded it all nice and smooth and applied a primer coat.
One good result from this effort was the ability to take a large paint chip down to the paint store where they have a tool to read the color from a customer’s sample and provide a formula to match it. This yielded a color similar to Navajo white and we decided on this color for all the walls and trim (baseboards, window sills).
We applied some of this paint to an existing surface of this color and we can’t tell the difference between old and new. This gives us the option to repaint a wall entirely (like those of a different color), or to simply touch-up areas with the original color that need it. We are amazed at this technology and are pleased with how it is turning out.
