Painting the inside or outside of a home once involved a paintbrush or paint roller. These tools added hours to an ordinary job because the painter had to continuously lean over and grab more paint from the bucket. The invention of the paint sprayer completely changed the way people thought about painting. The sprayers work on a variety of different surfaces, including brick, stone work, metal, wood and even plastic.
How to Use it
Sprayers are very simple to use, even for beginners. The bottom consists of a small plastic, metal or glass bucket that holds the paint. The painter pours the paint inside the bucket until it reaches the fill line, and then snaps the bucket onto the bottom of the sprayer. He presses down on the trigger, which sends a small amount of paint through the nozzle. This step also removes any air trapped inside the nozzle and lets the paint come out evenly.
The painter stands at least six to eight inches away from the surface and presses down on the trigger. He slowly moves the sprayer back and forth across the surface. The paint slowly dispenses from the sprayer and attaches itself to the surface. He can also apply the paint vertically, but he should move from the top down, which prevents streaks and keeps the paint from dripping down the painted item.
Sprayer Types
All sprayers fall into one of four categories: cup, HLVP, air or airless. A cup sprayer is a smaller device best suited for those that need something for DIY projects. It holds a small amount of paint and has an electrical cord that plugs into any outlet. Air sprayers work with compressed air for a smooth and even coat of paint on any surface. The sprayer is suitable for home improvement projects, automotive painting and painting of large surfaces.
Airless sprayers rely on constant pressure, which keeps the paint moving through the nozzle. The device works equally well with both thicker and thinner paints and stains. It features a design for larger projects, including the painting of an entire house. HLVP sprayers feature compressed air that slowly pushes through the nozzle as the paint comes out to prevent clogs. The sprayers do not work well with thicker paints and the devices are sometimes too expensive for DIY enthusiasts.
Using the Sprayer
Applying paint with a paint sprayer provides an even coat of paint on the surface of the item. The further the painter holds the nozzle from the item, the less paint hits it. Keeping the sprayer a foot or more from the object gives the item a light and even coat of paint. This lets the painter decide how much he needs to completely cover the surface.
Stop Paint Clogs
The biggest problem that occurs with the sprayers is clogs. The clog relates to the paint coming out of the nozzle. Keep clogs from occurring by letting the sprayer sit for only ten minutes or less. If the sprayer sits for up to 20 minutes, the paint starts hardening inside, which can lead to clogs. Cleaning the tip of the nozzle with a toothpick and cleaning the device with fresh water after painting can also prevent clogs.
