You can help keep your exterior looking its best between paint jobs by performing some basic cleaning and maintenance as needed. This includes inspecting your exterior yearly for signs of damage, wood rot, insect activity, or mold. Addressing these issues quickly can help prevent them from getting worse. You can clean and remove dirt, debris, and moss from your siding using a pressure washer as needed.
Prep work should include removing all loose paint, either with a pressure washer or by scraping; removing any trace of mildew using bleach and water or a commercial solution, and sealing or covering dark stains; caulking all seams, corners and around windows or trim; applying epoxy filler to repair serious woodwork problems; covering dark stains; sanding all rough surfaces, and priming the bare wood with a bonding primer.
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 Louisville Colorado
Whether you decide to do the preparation work yourself or have a professional do it as part of your project, proper preparation makes all the difference in creating a smooth and lasting finish. Do it correctly the first time or you’ll quickly end up spending more to fix peeling and chipping paint. Follow this process before starting on your home's exterior. Keep in mind that the process may vary based on your siding materials:
Most surfaces that are being painted for the first time or that are making a significant color change need to be primed before they can be painted. Primer helps the paint adhere better to the surface, so it will last longer. In some cases, primer can also help prevent discoloration of the paint, such as is the case when painting cedar; cedar sap can bleed through paint in a condition known as cedar bleed. Priming blocks this sap discoloration so the paint job stays looking fresh longer. If you are making a significant color change, from light to dark or dark to light, primer can help bridge the gap more easily, cutting down on the number of finished coats of paint.
To calculate the cost of an interior paint job that you do yourself, measure the square footage of the interior space you need to paint. Consider whether you will need primer or multiple coats to help with your color transition. If you’re just adding another layer of the same color of paint you used a few years back, you may be able to use a single coat and skip the primer. House Painting Louisville Colorado
