Using a paint sprayer can virtually change the game, in terms of efficiency and time taken, as well as achieving a perfect finish. However, knowing which techniques to use for each type of spray is what separates amateurs from professionals. This applies to spraying wood, spraying metal or bricks, and any other materials. In any painting or coating project, knowing how to use a paint sprayer will always give you the best results. Here’s a quick overview of the most efficient techniques when using a Graco TC Pro Cordless Handheld Airless Sprayer Parts on different types of surfaces.

Wood Surfaces
Wood is one of the most frequently used materials in outside projects, such as fences, decks, or furniture. The most serious setback of spraying any narrow surface, in this case, wood, is how perfectly smooth one can coat the surface without the paint soaking into the grain of the wood.
Techniques for Wood:
- Prep and Sand: Prior to spraying, ensure that the surface is in the correct specification and smooth. Wipe any dusty areas, fill up any cracks, and sand down uneven parts.
- Primer Application: Carry out primer application prior to any painting activities in cases where there is a lot of bare wood. It protects the wood and prevents the paint from drying in the veins.
- Distance Matters: It is important to keep a distance of about 10-12 inches from the surface from which you are airbrushing. If too much of the airbrush is too close, you risk drips and uneven application will apply; if too little, it will result in a patchy and bite coat.
- Thin Coats: Apply multiple thin layers of paint to ensure the application of undisturbed surfaces, thinning each coat with an appropriate solvent and allowing it to dry adequately before application of the other layers. This enhances the coverage and counteracts the runs.
- Back Brushing: Follow the same as above, but after spraying do not, just flick, but use a brush and smooth a little and only where it is physically difficult otherwise; usually at the line joints and ribs. This helps to spread and level the brightness and hides any evidence of overspray.
Metal Surfaces
For furniture, fences, garden sculptures, or any other painting of metal surfaces, the painting process gets complicated because metals are light and shiny. Preparation has to be done correctly so that the paint can stick properly and not wear off easily over time.
Techniques for Metal:
- Prep and Prime: Before painting, metal surfaces have to be free of rust, oil, dirt, and dust. Ensure you wash the surface well and if rust is present, scrub it down with sandpaper or a wire brush. Get a metal bonding primer to make sure the paint sticks and doesn’t rust like Graco X7 and LTS 17.
- Use the right paint: Always ensure the paint used is paint made for metal finishing. Using normal paints will promote the peeling or chipping of normal paints applied over metal surfaces.
- Keep Paint Boom Inside the Shielding Boom: When working on metal materials, they are typically smaller and thinner as compared to wood or bricks and therefore tend to be painted using a narrower spray pattern. Stick to the same height and operate the sprayer using the bow and slide movement.
- Light Coating in Separate Step: Due to the nature of wood; it is always advisable to apply paint, in several thin layers, thus enabling better adhesion to the material and a finer smooth finish.
Brick and Masonry Surfaces
Compared to wood structures, the brick, stucco, and other masonry surfaces present challenges due to their porous and rough contours. Such irregular surfaces may make it difficult to use spray paints as required for proper coverage without blocking or jamming the sprayer.
Techniques for Brick, and Masonry:
- Prepare The Surface Completely: Scrape off the surface dirt, dust, and loose particles of mortar using a wire brush or a pressure washer. This is important to note since dirt will affect how the paint bonds to the surface to be painted.
- Use Special Spraying Machine with Higher Capacity: Because masonry surfaces usually soak up paint, one manages to achieve evenly and adequate coverage through spray guns that have higher volumes or on settings with higher pressure.
- Sealant Application. After the paint has dried, it is advisable to apply a clear sealer in order to prevent moisture and damage to the paint.
Concrete Surfaces
Concrete decorative painting can dramatically change the appearance of driveways, patios as well as walls. On the other hand, this ‘cheap’ aspect, with the use of concrete paint, becomes ‘expensive’ in seeking perfection in appearance due to the porosities of the surface.
Techniques for Concrete:
- Surface Preparation: As for bricks, the surface of a concrete structure should be cleaned before the paint application. Pressure washing is encouraged for cleaning dust, and oil, or even getting rid of old paint.
- Multiple Coats: When applying paint to concrete surfaces, it may be necessary to apply a few layers before the surface is adequately covered. Apply in thin layers making sure each one is perfectly dry before the next one is applied.
- Seal for Durability: If it is an outdoor project, a protective coating should be applied after the final coat of paint so that the paint doesn’t chip and crack over time including the sides of buildings.
Conclusion
The paint sprayer is a design tool that when used well, saves time and effort and enhances the quality of work done especially on painting projects. Mastering the various surface techniques is the most vital ingredient of this success. If the solution is sprayed and each surface is correctly prepared, the right sprayer and the right way of painting are therefore not a problem, professional wood, metal, brick, concrete, plastic, and glass are all achievable. With commitment and a sharp eye, mastering spraying is as easy as A B C and this assures you that you will do anything with absolute ease.
