There are a number of measures you can take to prevent mold on the exterior of your home. Anti-mold paint works to stop mold from spreading. Still, anti-mold paint does deteriorate when exposed to prolonged sunlight and moisture. To prevent mold damage from spreading, it’s best to act fast. In order to ensure that all the mold is eradicated, we recommend calling a professional mold removal company.
However, some water-based paints are easier to work with than others. The first coat of paint may not provide complete wall coverage, or the color may not be quite as saturated. Some of these problems can be addressed with a separate primer coat, but this is a time-consuming project. The ideal solution is using a higher-quality paint that combines a primer and a finish paint in a “one coat” product.

For trim and doors, start with 1 gallon (3.8 L) of trim paint for every 600 sq feet of floor space. Purchase more at the store if/when needed. Trim is something that is difficult to calculate exactly, and it is more time-efficient to simply start with less than you need, and go buy more after you have used up the first round of paint and determined how much you will need to finish by seeing how much you have painted so far, compared to the gallons used.
Paper drop cloths: $3 to $5 for 9x12-feet. Paper drop cloths provide a cheap way to cover furniture or windows while painting small, indoor jobs, such as touching up window trim. They're absorbent and textured to hold paint. When you're finished, you can just fold them up and throw them away. However, paper cloths are not the best option for protecting floors since they can tear easily.
Paint acts as a protectant on wooden siding, slowing down the rotting process. This makes it incredibly important to fully coat the undersides of corner boards on the exterior of your home. Whether you’re undertaking a DIY house painting endeavor or have hired professionals, you should check corner boards and shutters to make sure they’re fully painted.
Begin prepping your walls by removing any outlet covers or lighting fixtures (if possible). Next, inspect your walls for any defects. If you encounter cracks, dents, or holes in your walls, simply fill them in with caulk or spackling compound. There are also a number of DIY tips to fill nail holes. Once your repairs dry, smooth them down with sandpaper and wipe the walls down with a damp sponge.
Another type of paint is on the market that claims to be a primer and paint in one. Basically, it’s just thicker paint and costs twice as much as regular paint. Most professional painters aren’t fans, but if you have exterior walls in excellent condition already, and the self-priming paint is the same color as the original paint color, it could certainly save painting time with one coat going on instead of two.
You can expect to pay between $700 to $3,000 to paint wood siding. You’ll end up spending $1 to $3 per square foot, but typically you’ll find this material is cheaper than brick or vinyl. Wood requires some type of sealant, be it paint, stain or oil. Lumber takes well to a wide variety of coverings giving you endless options for modern, contemporary or classic looks.
