At least 90% of painting time goes into setup, prep work, and priming. The method of prepping required varies for each type of exterior material on the home, but every project must be patched and cleaned. The more thoroughly you prep and prime your home’s exterior, the longer your paint job will last. You could save quite a bit if you do this part yourself, but it must be done correctly, or your contractor will have to go over what you missed. The prices mentioned are based on paying a contractor to do each job rather than one overall quote for the work from start to finish.

Of course, paint brushes and rollers are also important line items on your budget sheet. A 3-inch-wide paint brush costs, on average, $10 to $20—though you'll likely need an assortment of paint brush sizes for trim, corners, and narrow surface areas. Brushes come in a variety of bristle types and qualities, and each has a different purpose. Some are intended for specific paint types, finishes, and surfaces, so be sure to buy the right brushes for your painting job.

Supplies and Equipment – Scraping, sanding, and stripping tools and supplies; patching compound; power washer rental; primer; caulk; masking supplies; painters’ tape; ladders and scaffolding; paint pans; brushes, sprayers, and roller brushes all cost money, even if you do it yourself. Consider all of those tools and equipment sitting in your garage for the rest of your life vs. paying an experienced painter to do it all for you at a price that saves you weeks of time. Expect to pay $5–$6 per 100 sq. ft. for supplies and materials.

Paint supplies cost anywhere from $10 to $100 or more depending on what you need. Painters will typically provide most of the supplies for a project, but sometimes they will allow you to pay for solely labor if you provide all the materials yourself. You might decide to do a DIY paint job down the road. In which case having these supplies on-hand will save you time and money.
You’ll spend between $500 and $3,000 or $1 to $3.50 per square foot to paint concrete. However, expect to pay $2 to $7 per square foot since concrete almost always needs a coat of primer first. Double that price if the concrete requires stripping. Concrete is porous. Sealing it not only helps blend foundations and walls with your home’s aesthetic, but also seals it against water. Repairing or resurfacing concrete costs $300 to $500 for every 100 square feet.
