Painting the outside of your home is much more labor-intensive than painting the inside. Some people think that painting their exterior walls will be just as easy as painting their interior drywall. The process is much harder because you need to use thicker paint and the surface is usually much rougher. You also need to remember that weather conditions could make the painting more difficult. Painting your exterior walls will be much easier if you rent or buy a pneumatic spray gun. Here is how to use a spray gun to paint like a pro.
Masking and Taping Off
When painting your exterior, you need to do a lot more masking off. Overspray can be problematic, especially on a windy day. This is why you should wait for the weather to be good before you paint. No matter when you paint, you will need to extensively mask off using painter's plastic. Lightweight plastic sheets are often 0.2mm thick. This thin plastic is strong enough to protect against large spills and light enough to be tape over window and door fixtures.
First, cover all the door, window, vents and eaves with the plastic. Tape the edges of wooden frames tightly using 2" wide painter's tape. You can also drape the plastic over bushes and grass directly underneath the walls you are painting. Cut a large square sheet that you move along with you as you progress in your painting (so, don't tape it down). To cover the ground, you should use construction paper. This is safer to walk on than the plastic. It also provides better grip for ladders or scaffolding.
How to Spray Like a Pro
First, you need to realize that you are not going to be able to paint like Picasso the first time you use a gun. Practice on a throw away piece of wood or plastic before you start spraying your walls. It is important to never hold the trigger down while the gun is stationary.
In fact, you should start by spraying at an angle and then moving your arm across the wall. Go back and forth, without ever stopping. Try to keep the nozzle an equal distance from the wall whenever you are spraying. It is also very important to thoroughly clean your gun nozzle after every paint sessions. If the gun is not going to be used for over an hour, you need to remove the nozzle and soak it in water. Once you get a little more comfortable with your spray gun, you will be able to paint much quicker. For assistance, talk to a professional like All Seasons Painting & Decorating.Share
