Exterior wood siding has never lost its popularity. Many opt for authentic wood siding and even if other materials are chosen, very often they go for the 'wood-like' look. The only downfall for exterior wood siding is its maintenance. One practical way to paint it is by using a paint sprayer. Here are the basic steps to follow to do this.

Step 1 – Cleaning the Exterior Wood Siding

Keep in mind that you need to wear appropriate clothing for this job. For this reason, make sure that while working you are wearing a hat, gloves, sunglasses, and sunscreen. In order to clean your exterior wood siding, utilize a pressure washer to get rid of any peeled-off paint, dirt or mildew that has accumulated on the wood.

Be careful when you are using a pressure washer because it is a very powerful tool and you risk damaging the wood if you do not handle it properly. If you want, you can make use of a solution made from bleach and detergent to remove the dirt and mildew. Pay attention as well when using bleach because it can be very dangerous for your health. Let the wood dry thoroughly for 48 hours.

Step 2 – Sealing the Exterior Wood Siding

If you notice that there is too much old paint peeling off the surface of the wood is cracked, apply a coating of sealer to avoid any further cracking of the wood and paint peeling off. You can also cover any peeled areas with latex-based primer. If you have any joints, cracks or openings of doors and windows, apply caulk to them.

Step 3 – Painting the Exterior Wood Siding

When using a paint sprayer, keep in mind that paint will come out immediately, as soon as you pull the sprayer’s trigger. In order to have excellent results, you should place your hand with the sprayer at the appropriate distance away from the wood. Ideally, about 8 to 12 inches away. If the paint sprayer is too close, the wood will be overpainted. However, on the other hand, if you hold the sprayer too far from the wood, you will release more paint in the air than onto your surface. Keep in mind that the appropriate distance depends on the paint’s viscosity and the pressure at which the paint sprayer is operating.

In order to prevent the area around the wood from being painted as well, cut many cardboard pieces and use them as a protective shield over the areas that you want to leave untouched with the paint. Put the cardboard pieces aside when they become all wet with paint. Allow them to dry and use them again later on. Keep a sponge and a bucket full of clear water nearby so that if any paint falls on such an area, you can remove it with ease.

Do not paint exterior wood siding on the side of a building that faces the sun. You may have to turn the wood around before you finish the other side. Remember also to allow one color to dry thoroughly if you are going to use multiple colors to paint your exterior wood siding.
