Stripping – $54–$151/100 sq. ft.. “The principle of paint strippers is penetration of the paint film by the molecules of the active ingredient, causing its swelling; this volume increase causes internal strains, which, together with the weakening of the layer's adhesion to the underlying surface, leads to separation of the layer of the paint from the substrate.”— Wikipedia. All the stripper will do is soften the paint. You’ll still have to scrub or scrape it off. House Painting Thornton
One of the most common mistakes people make when it comes to exterior painting is skipping the primer. Applying primer is as essential to a quality paint job. In case the surface has never been painted before or if it has been thoroughly cleaned and stripped of previous paint, applying primer is paramount. You wouldn’t want the paint to adhere unevenly, right? So, apply a few coats of primer, finish up the prepping phase and only then move on to the painting. Thornton Home Painting
Scrub, then patch. Dirt, mildew, and chalky old paint prevent fresh paint from adhering properly. If your house was built before 1978, there might be lead paint below the surface. (See CR’s step-by-step guide for using a test kit to check for lead paint.) In that case, you’ll need to use a certified lead-abatement contractor to prep the surface. Otherwise, scrub the surface with a wire brush or scrub pad, or very carefully with a pressure washer, and clean with a detergent such as Red Devil TSP. Thornton House Painting
First of all, you have to get rid of old paint. That means, grab a paint scraper or a wire brush and get to work. It might be a little bit time consuming depending on the size of the house and how much paint you need to get rid of. If you want to speed up this process, there are electric paint removers out there that will make this job a lot faster and easier.
