The most important step in exterior house painting does not involve a paintbrush or a paint roller. In fact it doesn't involve paint at all. Preparing the surface of your home prior to painting will make or break your exterior paint job. It is rarely the paint itself that fails over the years but rather the adhesion of the paint to the surface below or substrate. The #1 reason paint fails to adhere is because the surface to which it was applied was either dirty, wet or was loose itself. Or possibly all 3. So making sure your paint surface is clean, dry, free from grease, oils and flaking or loose paint will give your primer and paint a good substrate with which to bond. Painting the exterior of your house over a dirty or poorly prepared surface is like building a house on a bad foundation, and no one is going to do that.
Before you begin your Denver exterior home painting project you will first need to do some prep work around the house. You will need to protect the surrounding landscape plantings, air conditioning units, BBQ grills and such from cleaning agents, paint chips, paint splatters and other debris. Always use canvas drop cloths to cover all delicate plants that could be damaged. Never use plastic since they do not breathe like canvas and the plantings will swelter under the plastic sheets.
After the prep work around the house is complete, it's time to prepare your home's exterior. One method used to clean the house and at the same time remove loose paint is power washing. A power washer uses water from your garden hose and increases the water pressure as it leaves the pressure wand to between 2,000 to 3,300 psi. This tool can be useful, however in the hands of someone inexperienced it can cause damage to your home. Power washing is no substitute for hand scraping. Since the power washer does not fully remove all loose paint, the wall still needs hand scraping after the power washing and drying period.
Once the loose paint is scraped away and all remaining paint has good bond to the substrate, the next step is to sand the surfaces. Before sanding, be sure to fill any cracks or holes with exterior wood filler and let dry. If you have any large areas that need patching, you should replace the wood instead of using wood filler. It is important to blend and minimize the hard edge visible at the seam of where paint has been removed and where it remains. Feathering is especially important on wood siding since siding is smoother than say a painted brick surface where surface irregularities are less noticeable.
After the surrounding landscape and appliances are protected with drop cloths and the substrate is scraped and sanded, it's time to give your house a good washing. A substrate free of dirt and grease is essential for the primer and paint to properly adhere.
