Dino-Power Airless Paint Sprayers Blog

• Airless paint sprayers can make painting a wall much easier and take less time. There are some tips that can help make using the sprayer and cleaning up afterward much more effective, especially to a new user of the machine. Keep in mind that it is a high-pressure tool that needs to be used with caution.
Coverage
• When using airless sprayers, there is often overspray due to the high pressure. Cover everything that is not meant to be painted with plastic. All your floors, furniture, and light fixtures need to be protected so no paint will get on them. Also, use painter’s tape on areas like your baseboards, doors and windows.
Pressure and Movement
• Maintaining even pressure and arm movement will create an even coat on the wall. Getting different tips for your sprayer will make a difference in the pressure. If a smaller area is being painted, move your arm in a line back and forth. If it is a larger area, use a wide fan-like motion. Should the paint be uneven, go back over it with a paintbrush. When the trigger is release on the sprayer, the paint does not stop flowing immediately, so keep your arm moving past the wall or edge of the object your are painting.
Practice
• Practicing is very important with airless spray painters. Get used to the pressure before you begin working. Also, it is a smart idea to experiment with which tips you think will work best for your job. Some machines allow you to adjust the amount of pressure that is released, so play around with that until you are satisfied. Use pieces of scrap wood, cardboard or layers of newspaper when practicing.
Cleaning
• Cleaning the airless spray painter immediately after use ensures that you can use it again. An effective way to do this is to run a cleaner through it. For example, if you used water-based paint then run water through the sprayer. If you used an oil-based paint, you are going to need to run something with paint thinner or other cleaning materials through it. Make sure your sprayer and area will not be damaged by these chemicals.

• Airless paint sprayers force paint through a small opening or tip with high pressure via a pump mechanism. Electric, gas and cordless models make short work out of a deck, house exterior or fence painting job. The lack of an air compressor makes most airless paint sprayers highly attractive to the average home improvement enthusiast. Before your next painting project, consider the different kinds of airless paint sprayers on the market today.
Diaphragm Pump
• A majority of the home-use airless paint sprayers utilize a diaphragm pump. The diaphragm pump pulls the paint from a container and forces it through the hose and gun. The mechanics involve a piston and hydraulic fluid, which cause a rapid up-and-down movement of the diaphragm to atomize the paint. Most diaphragm airless paint sprayers can only handle low-viscosity paints. In many cases, latex paints will require thinning before use.
Piston Pump
• For jobs requiring thicker paints and varnishes, check out piston pump airless paint sprayers. The main components of a piston pump include a main piston, packings and check valves. The piston moves up and down, pulling the paint up and then out through the hose. The packings provide an airtight seal on the reservoir to eliminate pressure loss while painting. Check valves provide another level of performance enhancement, preventing the paint from flowing back into the vacuum tube.
Twin Stroke Piston
• If you plan on tackling large painting projects on a regular basis, investigate twin- or double-stroke piston airless sprayers. Think of the twin-stroke, piston sprayer as the “Cadillac” of the airless paint sprayer category. Twin-stroke models command a high price, but their improved performance and extended life make them a solid investment for the regular painter. The double-stroke piston mechanism allows for consistent paint spray and little wear and tear on the parts and motor. Some models of the powerful twin-stroke sprayer accommodate two painters by simply attaching a second hose to the unit.
Compressor Assisted
• This kind of airless paint sprayer combines quick results with high finish quality for use in professional applications. The compressor-assisted sprayer provides high volume/low pressure output and the speed of airless painting in one piece of equipment. Paints move at lower pressure than conventional airless sprayers and partially atomize through a finer tip. To achieve full atomization, the sprayer introduces a small amount of compressed air to the edges of the spray fan. The added air results in a fine, professional finish. The benefits of this hybrid airless system include a soft spray pattern, increased control of flow and minimal over spray.

Without an airless paint sprayer, it takes days instead of hours to paint a house. Hard-to-paint surfaces such as acoustic popcorn ceilings or fences are difficult and messy to paint by hand but are a snap with an airless sprayer. The sprayer can be frustrating to use if not cleaned or maintained properly. Work stoppages due to a balky sprayer can make you tear your hair out; a single piece of grit in the paint can make the machine quit working. Troubleshooting an airless sprayer is a bit easier when you know how it works and can make quick on-the-job adjustments.
Difficulty: Moderately Challenging
Instructions
Things You’ll Need:
• Crescent wrenches
• Paint strainers
• Paint buckets
• Hammer
No Pressure
1. 1
Check the level of paint in the bucket or hopper first if the sprayer doesn’t build up enough pressure to spray. If it’s below the level of the intake filter, it’s sucking up some air along with the paint. Refill the paint bucket, remove the spray tip and run the sprayer for several minutes to purge air from the system.
2. 2
Thin your paint according to both sprayer manufacturer and paint label directions. More powerful contractor-grade airless sprayers can pull up and spray thick paints without a problem, but smaller sprayers often cannot. Make sure you’re using the correct size spray tip for the material.
3. 3
Tap the metal inlet hose housing (where the pickup tube attaches to the motor) sharply several times with a hammer. A ball valve inside can become stuck, but it’s easily jarred loose.
4. 4
Check the filters. If they’re clogged with dried paint or grit, the machine can’t build up pressure. Check the pickup tube filter first. If that is fine, turn off and unplug the sprayer, and check the bowl or inline filter. You will probably need a crescent wrench for these. Rinse them clean, or replace them if the paint has dried. As a last resort, take the spray gun apart, and check the gun filter.
Improper Spray Pattern
5. 1
Match the spray tip to the material and the job. You can’t use the same tip interchangeably for semi-transparent stain and latex paint. Spray tips are relatively inexpensive, and every sprayer dealer or paint store carries them. Worn spray tips will also cause uneven spray patterns.
6. 2
Check the pressure setting. If the spray pattern is weak and “grainy” looking, increase the pressure. If the paint runs and drips, turn the pressure down a notch.
7. 3
Strain the paint if the tip keeps clogging; there is probably debris or grit in there. It’s a good idea to strain all your paint through a strainer into a clean bucket in the first place, even if you are opening brand new cans. Keep the sprayer covered with plastic sheeting if you’re working in the sun or in a dusty environment to prevent the paint from skinning over or debris from falling into it.
Tips & Warnings
• Cleaning your airless sprayer and all the filters meticulously after every use and always storing it filled with mineral spirits instead of water will prevent a lot of problems.
• Use the throat seal liquid or lubricants suggested by the manufacturer on the recommended schedule.
• Always bleed pressure from the sprayer before dismantling any part of it. The pressure release valve is usually on the side of the motor housing. Once you’ve done that, unplug it from the power source.

Airless sprayers atomize the paint by forcing it through the tip of the sprayer, creating a flat fan of paint. Save time when painting textured or multiplaned surfaces difficult to paint evenly with a brush or roller by using an airless sprayer instead. When used correctly, airless sprayers can help you paint surfaces like stucco, shingles and latticework thoroughly and evenly.
Difficulty: Moderately Challenging
Instructions
Things You’ll Need:
• Drop cloths
• Tape
• Protective clothing
• Protective eyewear
• Gloves
• Airless sprayer
• Paint
• Thinner
• Solvent
1. 1
Use drop cloths, old sheets, plastic or tarps to protect a wide area around whatever you wish to paint, securing them with tape when possible. Because the paint is sprayed, it may land on surrounding surfaces.
2. 2
Wear gloves, goggles, a long-sleeved shirt and pants to protect yourself. The paint is coming out of the sprayer so quickly that it can be injected under your skin if you’re not careful. Consider wearing a hood as well.
3. 3
If your airless spray comes with interchangeable tips, choose the correct tip size for the type of paint you’re using . Each tip is numbered; consult the manufacturer’s information to choose the tip that’s right for your project. Generally, lacquer, shellac, stain and water sealer require .009 – .013 tips; enamel requires .013 – .015 tips; oil-based and interior latex paint requires .013 – .017 tips; and exterior latex paint requires .015 – .019 tips.
4. 4
Fill the sprayer’s cup with paint. Depending on your painting project, you may want to thin your paint first to help you achieve a smooth finish. Consider using naphtha if using oil-based paint and latex paint thinner if using water-based paint. Follow the manufacturer’s instructions regarding how much paint and/or thinner to use in the cup.
5. 5
Practice spraying the paint on a disposable object or surface until you are able to use the least amount of pressure on the trigger necessary to achieve even coverage.
6. 6
Position the airless sprayer about 12 inches away from the surface you wish to paint and, with a steady hand, spray in a straight line at a speed of about three inches per second. Use your arm, not your wrist, to keep the airless sprayer straight. At the end of a strip, release the sprayer’s trigger and re-engage it as you go back in the other direction, overlapping the first strip by roughly one inch. Begin moving your arm in a steady, three-inches-per-second fashion before pulling the trigger; this will help you apply the paint evenly.
7. 7
Take a break if needed. Always set the safety lock when not painting. Keep in mind that the paint in the sprayer will start to harden after 15 minutes. If you must take a longer break or if you have finished your painting project, turn off and unplug the sprayer and clean it.
8. 8
Remove the sprayer’s tip and soak it in an appropriate solvent: water if you used a water-based paint and thinner if you used an oil-based paint. Then use the same type of solvent to rinse out the sprayer’s cup. Run the solvent through the sprayer’s lines until all paint is removed and the solvent comes out of the sprayer clean

• An airless sprayer is a device that is powered by electricity and uses a pump system to pull paint from a container, using force to push it through a hose and spray head onto the object that you wish to paint. There are many uses for airless sprayers, and, when used correctly, they can provide a fast and easy way to complete many paint projects.
Paint a Car
• If you have never handled a paint sprayer or attempted to paint a car before, it is probably wise to pay someone else to do it for you. If you are not afraid of the end results, however, using an airless sprayer on a car is a fast and efficient way to paint one, since the sprayer allows you to evenly distribute the paint over the curves and edges of the vehicle.
Paint a Fence
• Perhaps one of the greatest things about an airless sprayer is its time-saving ability when painting fences. Instead of using a paint brush for each individual board on the fence, simply hold the paint sprayer in position and complete one fence section at a time. The only downfall to this method is that paint can go through the slits of the fence, covering nearby bushes, trees or even the family pet.
Paint the House
• Start at the top of the house and paint your way down. The most common reason that people purchase airless sprayers is for the sprayer’s ability to paint large areas in a short amount of time. If you will not need the sprayer for future projects, consider saving some of the cost and renting one from a local home improvement center. They will be happy to advise you on the right airless sprayer and paint to use for the job.

Airless paint guns, also called airless paint sprayers, are useful tools for painting houses and other buildings. By using this type of paint sprayer, you can apply an even coat of paint more quickly and efficiently than with a brush or roller.
Function
1. These tools are typically used for exterior painting of houses and other structures. They may be used by professional painters, or by do-it-yourselfers wishing to paint their own houses.
Types
2. There are two types of airless paint sprayers. One type employs a piston pump to create a vacuum to draw the paint in one end, and then force it back out through the other end. The second type uses a diaphragm pump, which requires hydraulic fluid to cycle the paint through the gun.
Parts
3. In addition to the pump, airless paint sprayers are composed of a gun with a hose and a tip. The gun is the part held in the hand, with a trigger used to control the flow of paint, which flows into the gun from the hose and out of the gun through the tip. Guns are available in two- and four-finger models.
Considerations
4. When buying components for your sprayer, you will have a series of choices to make. For the gun, choose either a two- or four-finger model based on which is more comfortable for you to hold. For the hose, choose one that is rated for the maximum output, described in pounds per square inch (psi), of your pump. When choosing a tip, consult the packaging on the paint you will be using to discover which tips work best with that paint.
Warnings
5. If the hose for your sprayer becomes damaged, do not attempt to repair it. Instead, purchase a new hose to avoid the risk of injury or a ruined paint job. Additionally, do not attempt to use a tip that is too small for the paint you will be using. The thicker the paint you use, the larger the tip you will need.

You can still paint via the traditional paintbrush and roller,
but a paint spray system can cut your painting time in half or more.
Paint spray guns are typically powered by compressed air,
but “airless” sprayers are also available.
The sprayer is considered “airless” because the electric turbine creates a high pressure within the pump mechanism to push out paint.
DINO AIRLESS produce air sprayers and airless sprayers.
In order to paint a project effectively with an airless system you’ll need to know how to properly use the it,
which is a bit different from compressed air sprayers.
