For bigger houses or for faster work on smaller ones, rent a high-pressure spray cleaner. This device attaches to your home's water-supply system and puts out a jet of water at a pressure of about 600 pounds per square inch. It is equipped with a handheld wand tipped with a trigger-activated nozzle. The pressure is high enough to dislodge not only stubborn dirt, mildew, stains, and dried-on sea-spray salt, it's enough to remove peeling paint. In fact, if the jet nozzle is held too close to the surface it can even peel off perfectly sound paint, split open shingles, and drill a hole in siding. So follow the manufacturer's directions and wear goggles and protective clothing.
All colors have a base tone which might not be as apparent on a small swatch, but when the color is painted over an entire wall or room – the base color will stand out. Brown colors will sometimes appear to have a pink hue to them, and greys very often have some purple or blue to them. To avoid being surprised by a base color, take some time to look at the color fan deck for the selected paint color to see where the color comes from.
If there is any peeling — and there usually is somewhere — it's essential to scrape off any loose paint. This doesn't just mean the parts that are already separated from the wood and ready to fall off on their own. Each spot where paint has peeled loose needs to be scraped thoroughly until you can no longer get the sharp corner of a putty knife under any of the surrounding edges of paint. Then, the bare spot needs to be sanded until the paint edges are smooth.
