Paint sprayer machines are a great tool for painters looking to take on large painting projects or achieve an even finish. With the right technique, paint sprayers can help you achieve a smooth, professional-looking paint job on walls, ceilings, doors, furniture and more.

Prepare the Paint Properly

Paint preparation is key to avoiding clogs and getting an even finish. Start by straining the paint through a fine mesh strainer or filter to remove any chunks or particles. This is especially important for older paint.

Check the paint's viscosity - thin paints may need thickening while thicker paints can be thinned with water. Paint should flow easily and evenly off a stick or through a viscosity cup. Refer to the paint directions for the ideal consistency.

Proper Thinning Ratios:

Latex paint: Add 1/4 cup water per 1 gallon paint

Oil-based paint: Add up to 1/2 cup mineral spirits per 1 gallon paint  

Stains: Thin up to 50% with recommended thinner

Setting Up the Spray Area

Choose an outdoor area or a room with plenty of ventilation and cover any nearby surfaces you don't want painted. Lay down a drop cloth to catch drips and overspray.

Hang painter's tape along the walls 2-3 feet up from the floor to protect them from stray spray. Also mask hinges, fixtures, outlets or trim with plastic sheeting and tape.

Priming and Preparation

Always start by priming bare drywall, wood, metal and other absorptive surfaces before applying colored paints. Primer helps the topcoat adhere evenly. Sand glossy surfaces lightly before priming to help it bind.

Fill any cracks, holes and imperfections with spackle; let dry fully then sand smooth. Finally, wipe down the entire surface with a tack cloth to remove dust right before spraying.

Setting Up Your Sprayer

Securely attach the hose to the gun and check for any air leaks. Attach the correct spray tip for the paint and job. Tips with smaller orifices produce finer atomization for detail work. Larger tips are needed for spraying thicker coatings.  

Adjust the controls to the proper settings for your paint's viscosity and desired spray pattern (horizontal fan, vertical fan or round). Adjust the flow control knob and regulator to achieve 25-40 psi for light coatings or 75-100 psi for latex house paint.

Time to Paint

Move the sprayer at a consistent speed, overlapping each pass by about 30%. Keep the sprayer perpendicular to the surface, about 8-12 inches away. Quick sweeps works better than holding it stationary.

Maintain consistent motion to avoid drips, runs and heavy buildup. Work in sections of 2x2 feet. Apply multiple light coats rather than one heavy coat for the best finish. Allow proper drying time between coats.

For corners and edges, spray perpendicular to adjacent walls. For balusters and decorative trim, spray vertically to cover all sides evenly.

Clean Up Properly

Follow all cleanup and storage steps in the owner's manual. Thoroughly rinse the sprayer, cups and hoses with warm water to remove residual paint and prevent clogging. Wipe the sprayer exterior clean. Store upright in a dry area.

Dispose of wash water appropriately as latex paint can harm the environment. Strain it through a cloth into a bucket first so pigment doesn't go down drains. Allow to dry fully before discarding or use a paint hardener product.
