If you want a big bang for your renovation buck, painting the exterior of your house can make a huge difference. Before you get started though, make sure you avoid these 4 common house painting mistakes.
First, you need to make sure that the surface you are going to paint is ready. On wood, run your hand along the siding. If a chalky residue is left, you need to wash the house down with trisodium phosphate (TSP). This is a caustic substance; so take proper precautions before using it. Wear gloves and eye protection, and cover nearby foliage. After applying TSP, rinse the area thoroughly with water. Seal the areas you are painting with an alkyd primer to prevent bleeding through the paint.
Next, inspect the structure for loose paint and imperfections. Use a scraper or sander to remove any loose paint, and fill in any holes with a quality Spackle. Once the Spackle is dry, sand it down and reapply the primer. Sanding all the surfaces with 125 grit sandpaper will help the paint adhere to your surface.
Spills and runs happen while painting. Masking off the places where you do not want paint can save a long clean up when the job is over. Not only should you mask off trim and cover windows, also make sure you mask off places where you do not want paint to bleed, such as vents and downspouts. Use quality masking tape, and carefully remove it as soon as the paint has dried.
Choosing The Wrong Paint Type
There is a definite difference between indoor and exterior paint. Choose a high-quality acrylic latex exterior paint. Latex paint is basically an elastic seal on the outside of your house that will withstand weathering, and expand and contract with the changing temperatures.
Speak with painting professionals to see what they recommend. Choose a paint that works on your particular exterior, and the typical weather patterns in your area.
Once you have selected your paint, begin by cutting in around doors, windows, along the edges of overlapped siding and along the top of the siding where it meets the fascia. Once this is complete, you can use a 3/4 inch roller to finish the job. Watch for runs in the paint, and correct them before they dry. You should wait at least 24 hours before applying a second coat, if necessary.
Painting In The Wrong Weather
Weather can play an important factor in how smoothly your house painting job will go. Obviously, you cannot paint in the rain. You should also wait until the morning dew has burned off before beginning.
Painting when the temperatures are above 90 degrees is not only dangerous to your health; it causes the paint to dry improperly. On the other hand, you also do not want to paint when the temperatures are close to freezing. A frost at night over your new paint job can ruin all your hard work.
