Homeowners with wood siding have the option of staining or painting siding that has been worn down by the elements -- especially if they need to increase its defenses against the sun or extreme humidity. Holes, missing pieces or other problems will increase the overall cost of the painting project. You can expect to pay between $700 (~250 sq. ft.) and $2,000 (~1,000 sq. ft.) to paint wood siding, but this project will also help to protect the home's exterior from more extensive repairs down the road.
Freshly painted walls often look blotchy. The color is uniform, but the sheen isn’t consistent. This usually occurs over the holes and cracks you patched with a filler or drywall compound. The porous fillers absorb the paint, dulling the surface (a problem called “flashing”). When light hits these dull spots, they stick out like a sore thumb. The smooth patch also stands out in contrast to the slightly bumpy texture of the rest of the wall. A quick coat of primer is all it takes to eliminate ﬂashing and texture differences.
When you go to the home improvement store, find out how much 12 gallons of the paint you want would cost, and that will help you determine your cost. Maybe it's a low-quality paint that costs $30, in which case you're looking at about $360 for paint. If you choose high-quality paint that costs around $70, your total paint cost could be closer to $840. Professionals also recommend that you add an extra 10 or 20 percent to your total square footage, depending on the type of siding you have. Some textures require extra paint because they're rough. This is especially true with wood and stucco siding.
