There are many ways of applying paint or other coatings to a surface. Thorough preparation of any surface to be coated is imperative to achieve a quality final finish.

Painting preparation usually follows these steps;

Clean or wash down the surface to be painted to remove all contaminants.
Remove all loose or poorly adheard old coatings.
Sand or abrade to promote adhesion for the new coatings and to improve the existing surface if required.
Fill any cracks, blemishes or holes.
Remove and clean up any debris and dust from painting preparation works before commencing painting.
Mask out any areas that are not to be painted and cover all areas not being painted with drop sheets.
The most common method of applying paint and other coatings in most cases is by using a paint brush. Load the brush with the coating then use the brush to spread the paint evenly onto the surface to achieve a consistent film build.

If broader areas are involved time to apply the coating can often be reduced by using a paint pad or paint roller, or even by spraying the coating onto the surface with spray painting equipment or a power roller.

Painting takes time, dont try to rush the job. Apply each coat as evenly as possible and avoid runs by not trying to apply too much at once. A better finish will usually be acheived by applying 2 or more even coats than trying to acheive coverage with one coat.

Check with the coatings manufacturer and follow the recommendations for any prepatory coatings such as primers and undercoats, allow the specified times between applying coats and apply the recommended number of coats at the specified thickness to ensure a quality finish is achieved and the coatings manufacturers waranties will not be voided.

Airless sprayers work by pumping out paint from a small tip on a spray gun. There are no air compressors, nor is air involved in any way to move the paint. Airless sprayers are very efficient and will apply paint very quickly over a large area. If you are using an airless sprayer to paint your car, there are a few things to keep in mind.
Difficulty: Moderate
Instructions
1. 1
Cover all areas of your car that are not to be painted. An airless sprayer is not as easy to control as a brush, so do not take any chances that you may accidently spray a mirror or glass. When spraying, the airless sprayer paint will create a cloud of paint that will settle. Wear a protective covering.
2. 2
Keep the spray gun aimed at the area that you want to paint. Never point it towards yourself. Move your hand in a horizontal motion while spraying. Do not stop to spray as you will create a heavy concentration of paint in one area.
3. 3
Begin moving your hand from side to side. Once you have a steady motion, begin to pull the trigger.
4. 4
Release the trigger before stopping motion of your hands when you are ready to quit painting.
5. 5
Clean the sprayer so that no paint builds up and dries up inside.

Tips & Warnings
• Do not mix oil-based and latex-based paints in the spray. Never mix a paint thinner with a latex paint.
• Sprayers operate at high pressure, do not spray yourself or any one around you as this may cause injury.

Instructions

 

Things You’ll Need

  • Paint Sprayer
  • Extension Cord
  • Drop Cloth
  • Spray Shield
  • Rags
  • Ladder

Set-up Sprayer and Start Practicing.

Before starting your painting project, reference the owner’s manual and read all of the warnings.

To get familiar with paint spraying, use a large scrap piece of cardboard or plywood and practice your spraying technique. Move your sprayer vertically and horizontally to get a feel for how the spray gun will distribute paint.

  • 2

    Position Sprayer and Drop Cloth.

    To ensure that your sprayer will not mix with any paint chips or dust, shake out any debris from your ground drop cloth. Place clean drop cloth below the area you are about to spray. Move drop cloth as you progress along siding.

  • 3

    Start Spraying.

    Hold the spraying perpendicular to the siding, moving in slow even strokes. Keep the spray gun at right angels to the surface. This means moving your entire arm back and forth rather than just your wrist. Overlap the spray by a third to ensure even paint coverage.

    In order to spray like a pro following these guidelines:

    - Keep each stroke smooth and at an even speed
    - Keep the spray gun perpendicular to surface
    - Do not bend wrist while spraying
    - When spraying, always trigger the spray gun after spray pass has begun and release trigger before stopping. This will avoid heavy paint built-up on the surface.
    - Get the best finish by spraying multiple thin coats rather than a few heavy ones.

    Spray Garage Door.

    Make sure you have cleaned the surface you are about to paint. If you have used water to clean your surface, make sure you have allowed a minimum of three days drying time. Place a drop cloth at the base of your paint location. Consistently move your sprayer across your garage door holding the trigger as you proceed.

How to Adjust an Airless Paint Sprayer

If you rent a paint sprayer to paint or stain your home, you will almost certainly be renting an airless sprayer. These handy tools make quick work of painting — you can paint the exterior of your home in a day or two, instead of spending countless hours (or weeks) doing it by hand. It’s frustrating when the sprayer doesn’t operate correctly, though. Most of the time the fix is an easy adjustment and you’re back to work within minutes.

Difficulty:
Moderately Easy

Instructions

things you’ll need:

  • Clean bucket
    • 1

      Turn the pressure control knob counterclockwise to the lowest setting before plugging in and flushing the airless sprayer. The pressure control knob is usually on top of the motor housing and can be turned by hand. All sprayers are stored with mineral spirits in the pump and need to be flushed before starting to paint.

    • 2

      Flush the mineral spirits with water or solvent (if using solvent-based material) and place the pickup tube and siphon in your paint bucket. Push the prime valve until it’s pointing straight down in the open position. The prime valve is a lever, usually on the side of the motor housing.

    • 3

      Trigger the spray gun into the bucket and allow the paint to flow until it is running smoothly without spitting or bubbles. Turn the pressure control valve up — for most paint it should be turned about 2/3 or a turn clockwise. Thinner materials, like stain and varnish, require slightly lower pressure. Install the spray tip, and you are ready to paint.

    • 4

      Increase the pressure a little if the motor runs but does not build pressure or if paint won’t come out at all, or comes out in a thin, weak spray. decrease pressure if the paint comes out with such force that you feel it “kicking” your hand back, or if it applies the paint too heavily in an uneven spray pattern.

    • 5

      Change to a new spray tip if no matter how you tweak the pressure, you cannot get the paint to flow in an even spray pattern without runs or spattering. Spray tips are replacement parts and can wear out quickly with some materials such as latex paint sprayed at high pressure.

    • 6

      Repeat steps 2 and 3 if the airless sprayer continues to be slow about building up enough pressure to spray.

Tips & Warnings

  • Strain paint into a clean bucket through a paint strainer or clean pantyhose before spraying. It cuts down work stoppages due to clogged tips and filters, and makes all the airless sprayer components last longer.

Paint sprayers are a wonderful aid to painting large areas quickly and efficiently. The problem with paint sprayers, however, is the nozzle through which the paint is actually sprayed. These nozzles have small openings through which the paint must travel, and these tiny openings can easily get clogged. They can become clogged if there are any impurities in the paint itself, or they can become clogged when paint left in the sprayer thickens or dries. Fortunately, there are relatively simple ways for homeowners to clean their airless paint sprayers after each use and keep their sprayers working just like new every time.
How to Clean Water-Based Paint
• 1
Clean your sprayer immediately after using. Replace the paint container with a container of warm water Spray this warm water through the gun, adding fresh water as necessary, until the spray coming out of your sprayer is clear. Do not run the same water through the sprayer twice.
• 2
Add 1 tbsp. of dish soap to the warm water and run a full cycle of warm, soapy water through the sprayer, making certain that the spray that comes out of the gun is clean.
• 3
Take the sprayer apart and soak all parts in warm, soapy water. Rub parts gently with your fingers if necessary to loosen and remove any visible paint.
• 4
Reassemble the sprayer and run plain warm water through the system if the gun will not be stored, but be used again regularly. If the sprayer is to be stored, especially over winter where it might freeze, run a small amount of paint thinner (never lacquer thinner) through the sprayer to remove any water which could freeze.
• 5
Soak any filters in warm soapy water as well, rubbing them gently with your fingers to get them as clean as possible. Rinse filters with running warm water to remove any soap once they are clean and allow them to air dry.
How to Clean Oil-Based Paint
• 1
Remove the paint canister and replace it with a can or jar of paint thinner (never lacquer thinner, which could damage internal parts of the sprayer). Run paint thinner through the sprayer until the thinner comes of the sprayer clean. Do not run the same thinner through the sprayer more than once.
• 2
Take the sprayer apart and soak all of the parts in paint thinner. Rub parts gently with your fingers to remove any paint if necessary.
• 3
Soak any filters in paint thinner and rub them gently with your fingers if necessary to remove any last vestiges of paint. Rinse the filter in paint thinner and allow the filter to air dry.
• 4
Reassemble the sprayer.
Tips & Warnings
• It is an excellent idea to have extra O-rings and spray tips on hand as these parts frequently need replacement, rather than a simple cleaning to keep your machine running like-new.
• Many sprayers have a “wet cup” that must be kept one-third full of Throat Seal Liquid (TSL) in order to work properly. Consult your owner’s manual.
• Some airless sprayers have a hose attachment which can be used to aid in cleaning water-based paints (but not oil-based paints or stains).

Airless Paint Sprayer Tips

172 comments

• 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.

An airless paint sprayer is the fastest and easiest way to paint just about anything. It has an electrically run hydraulically pump that moves the paint along through a tube from the paint can or bucket to a high pressure hose to a sprayer and out of the nozzle onto the painting surface. It’s an easy concept but it does take a little bit of a knack to do it well so plan on some practice time on some old boards or even newspapers before you use it anywhere that matters.

Difficulty:

Moderately Easy

Instructions

things you’ll need:

  • Paint
  • Water
  • Mineral oil
  • Stocking or pantyhose
  • Masking or painter’s tape
  • Drop cloths
  • 1

Start with the preparation. You need to mask off everything really well. A paint sprayer uses a fine mist that can speckle everything around it so keep the whole area around what you’re painting taped off and covered up with drop cloths, including floors (even if you’re working on the ceiling). Open the house up if you’ll be using this indoors and turn on exhaust fans if you have them. You’ll need plenty of ventilation, especially if you’re working with an oil-based paint which has much stronger fumes. Make sure you have on a hat, gloves, long sleeves and pants and glasses.

  • 2

Flush the airless paint sprayer with a cleansing solvent before each use. If you’re using enamel paint you can flush it with clean lukewarm water. For oil-based paints you need to flush it with mineral spirits. Each paint sprayer is a little different so read the instructions for specific details. What you’re doing is just running the water or mineral oil through the tubing and out of the sprayer.

  • 3

Thin the paint according to the manufacturer’s instructions. The type of paint and the type of sprayer determines exactly what the mix is so follow the directions exactly. If it’s too thin or too thick it will make a terrible mess and it could gunk up the sprayer so you’ll have to tear it down and clean it before you can use it again.

  • 4

Paint by holding the spray gun steadily at about eight to twelve inches from the surface so that the paint will go on uniformly. Make sure to keep the nozzle of the paint sprayer pointed straight ahead. If it’s tipped up or down it will have a heavier concentration of paint at the top of bottom that you’ll be able to see. Paint horizontally in a stripe about three feet wide going from the top of the surface to the bottom. Then overlap the next three foot section just a few inches and work the same way.

  • 5

Know the tricks of paint sprayers. The whole key to using this sprayer is to get the right amount of paint on the surface. Too little paint shows the surface underneath it and too much paint will make a mess by dripping. Move the gun a tiny bit before you start to spray to prevent paint blobs when you start. Also, let go of the handle just a split second before you get to the end of the area you’re spraying so it won’t blob up there. Never hold the sprayer still. As long as it’s spraying you have to keep it moving. Move it regularly at the same steady speed holding the nozzle straight for the best results. Although there are filters in the sprayer, many pros paint through a piece of old stocking to filter it even better.

  • 6

Know the safety tips. Never point the gun at anyone. The paint is released at up to 200 mph with up to 3,000 pounds of pressure per square inch which is enough to cause real damage. Don’t use this in an area with any ventilation as the fumes can cause you to become dizzy or worse. Keep your fingers away from the nozzle when it’s spraying. Don’t touch the tip at all when it’s on. Always unplug the unit before you clean it. After it’s unplugged, squeeze the trigger to release any paint left in the line. If you’re outside, keep all your supplies in the shade. Even the paint shouldn’t sit in the sun, now should any solvents you may be using.

Paint can be applied in a variety of ways.

There are a variety of different paint sprayers on the market. One of the most common is the airless paint sprayer, which is useful for large paint projects, such as a spacious living room.

  1. Function
  • Airless models use a high powered point on the end of the sprayer to push paint out onto the targeted surface. The amount of paint a unit can hold varies, from 1 quart in a smaller sprayer to multiple quarts or gallons if attached to a stationary paint holder.

Types

  • Airless paint sprayers come in three pump varieties, including the diaphragm pump, piston pump, and double stroke pump. The lower end diaphragm pumped sprayer is for the weekend paint warriors, whereas the higher end double stroke pump is mainly used by professional painters.

Significance

  • The use of airless paint sprayers allows the user to apply paint, from thin viscosity to thick viscosity, in a clean, even way. Also, it enhances safety by alleviating the need to bend and apply paint to a brush or roller multiple times during a job, which can stress the body or cause injury.

• 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.
