Exterior Paint Preparation Techniques for a Lasting Finish
You may think that superior quality paint is the most important aspect to a lasting paint finish, but you’re only half right; what’s primarily needed is proper paint and surface preparation. Paint must be adequately prepared to ensure that it won’t prematurely fail. This is the main cause of paint failures in a finish’s integrity. You must also prepare for ever-changing weather and sunlight conditions that your paint will have to stand up to.
Almost 50% of time devoted to painting projects is the prep work.
In tackling a painting project, the proper foundation must be laid, and you must know the extent to which your surface needs to be prepped. When setting up, take the entire home into account as well. Taking on a new painting project should be done with the upmost vigilance. Take one step at a time and address any areas that require repair .
The vast majority of the time, the areas that need extra care are the doors, windows, wood trim, and fascia boards. If you have light rot and damage, that can be handled with epoxy wood filler or bonding glue, but if an area is critically exhausted or rotten, it should be replaced. Seattle painting At Shearer Painting, we frequently restore fascia boards, window casings, and other exposed substrates.
Prevention Can Save Time and Money
Certain additions can radically enhance a paint finish’s lasting power and also avoid repairs in the future; adding items like metal flashing, which can protect your home from rain and ice, is a good idea. Often times, a home may be constructed without these additions, and all that’s used for protection is caulk. All fascia boards should have metal flashings that come out from the underside of the roof and overhang past the fascia. Metal flashings are important, as they provide proper roof drainage and can be installed even if they weren’t originally there.
Another area susceptible to rot are the areas where flashing over windows and doors should be, called, drip edge. Many homes have drip edges, but if your house is older, it may not have it, and only have caulking to seal the edges of the frame.
You should study your old paint’s current condition – it can indicate trouble areas. You can tell that you may have a water leak if you see an area with blistering and peeling or discoloration. Areas that are prone to excess moisture are more likely to have mold, mildew, and peeling paint. If mildew and mold does exist, it should be removed, and all leaks should be sealed before primer application.
Readying Your Exterior
Shearer Painting pressure washes shingles, siding, and stucco to remove chalk deposits on the current finish. A clean surface is paramount in providing a proper base for a new finish and is one of the primary steps in the paint preparation process. If your building is being restained, pay close attention to detail, as a clean surface is, again, of the upmost importance.
After a home is pressure-washed, we move on to scraping and sanding away loose paint. It’s good practice use both techniques and alternate between the two to ensure no loose paint is left on the exterior surface.
Make sure to use a wire brush when rough-cut wood, like rough sawn cedar is being prepared. Wire paint stripping attachments for power drills make the process smoother as well.
Preparation is one of the more physically demanding aspects to exterior refinishing, but it’s definitely the most important. By removing all loose paint from the surface, a groundwork for a lasting finish is being made.
Do it right the first time.
Lead paint is a major concern for homeowners today, especially in homes built prior to 1978. To take proper action in ensuring that you’re following lead-safe practices, research how to handle the situation; find a contractor, like Shearer Painting, that is an EPA certified lead renovator.
You’ll want to use the best quality items available to make sure that you have a great-looking and durable finish that won’t fail prematurely when masking, caulking, and priming. You should employ this technique when choosing paint and painting techniques as well. When choosing a painting professional, be aware of their credentials and references, as choosing a good contractor can save you time, money, and repair work.
Remember that some work may need a building permit and inspection. While a good contractor is very knowledgeable, he or she may not be able to take on your repair job by themselves because of their qualifications. In the United States, you may contact your local building authority for more information on permits and inspection. Canadian residents also have great resources like the one here, which have information on Canadian building permits.
If you take the proper time and care in prepping your home for a new paint job, you could have a finish that lasts 10 years or more.
