How To Choose and Use Spray Paint

Spray painting older pieces of furniture and decor is a quick and easy way to give your home’s interior a new look. From metal and plastic to wood and masonry, this versatile medium can transform old objects or add a pop of color to your latest do-it-yourself (DIY) project. In this guide, we’ll explore the different types of spray paint, how to choose the right one for your project, and key techniques for achieving a flawless finish. This Old House landscape contractor, Roger Cook, demonstrates proper spray painting techniques and shares valuable tips in the video above.

Types of Spray Paint

Spray paint comes in several finishes and formulations and has specific applications and surfaces.

Finishes

These are the most common spray paint finishes:

• Hammered: Produces a unique, dimpled metal effect
• High-gloss: Has a shiny, reflective appearance
• Metallic: Creates a lustrous, metal-like appearance
• Satin: Offers a subtle sheen with a smooth finish
• Textured: Mimics the look of stone or other textured surfaces

Specialty Formulations

For specific projects or surfaces, consider these specialty spray paint options:

• All-surface paint: Versatile option for use on wood, metal, plastic, and masonry
• Chalkboard paint: Transforms surfaces into writable chalkboards
• High-heat paint: Withstands temperatures up to 1,200 degrees Fahrenheit, ideal for grills and radiators
• Plastic-specific paint: Adheres to plastic surfaces

Choosing the Right Spray Paint

Before choosing spray paint for your project, consider the color, surface material, and environmental factors.

Surface Material

Different materials require specific types of spray paint for optimal adhesion and durability. Additionally, surfaces such as metal and plastic can benefit from a primer for better adhesion and a longer-lasting finish. Here are some paint recommendations based on your surface material:

• Masonry: Choose a paint formulated for concrete, brick, or stone surfaces.
• Metal: Select a paint designed for metal surfaces or use an all-surface formula.
• Plastic: Opt for plastic-specific paint or an all-surface option.
• Wood: Use a primer for raw wood before applying your chosen color.

Color and Coverage

When selecting a color, think about the existing color of the surface, your desired final color, and the number of coats required for full coverage. For darker surfaces or when making a significant color change, use a primer. This technique, highlighted by Cook, is essential for achieving professional results.

Environmental Factors

Factor in the conditions where you’ll use the painted item, and choose a paint that can withstand the specific environmental challenges your project will face. For outdoor projects, especially those exposed to the elements, select a high-durability paint.

Preparation for Spray Painting

Follow these steps to make sure your surface is ready for paint:

1. Clean the surface thoroughly with soap and water.
2. Remove any rust, dirt, or loose paint using wire brushes, sandpaper, or steel wool.
3. For plastic surfaces, use denatured alcohol to remove any oil residue.
4. Allow the surface to dry completely.
5. Mark off areas you don’t want to paint using painter’s tape and newspaper.

Spray Painting Techniques

To achieve a smooth, even finish, follow these spray painting techniques:

• Shake the can vigorously for at least one minute before use to mix the paint.
• Hold the can 12 inches away from the surface to prevent the paint from pooling or dripping.
• Apply the paint in a sweeping motion, keeping the can moving at all times.
• Use light, even coats to prevent drips and runs.
• Allow each coat to dry completely before applying the next.
• Apply a second coat for full coverage and a more durable finish.

Tips for Successful Spray Painting

When spray painting surfaces, work in a well-ventilated area or outdoors. If you’re painting outdoors, wait for a calm day to avoid wind-blown debris sticking to wet paint. Test the spray pattern on a piece of cardboard before starting your project to ensure even application. You may want to use a spray paint handle attachment to reduce hand fatigue and improve control.

Cleaning and Maintenance of Your Project

After completing your spray painting project, clear the nozzle by turning the can upside down and spraying until only clear propellant comes out. This prevents clogging for future use. Wipe the nozzle clean with a cloth or paper towel to remove any residual paint.

Store any unused paint in a cool, dry place away from direct sunlight to extend the life of your paint. Allow painted items to cure fully before use or handling. For painted outdoor items, periodically clean and inspect the surface for any signs of wear or damage.

Chalkboard paint and high-heat paint require specific maintenance. Clean chalkboard paint surfaces with chalkboard cleaner, and check items painted with high-heat paint for heat-related wear.

Advanced Spray Painting Projects

For enthusiasts wanting to take their spray painting skills to the next level, there are a few DIY projects you can tackle.

Creating Custom Furniture

Transform old furniture into unique statement pieces with spray paint. Start by sanding down the furniture to remove any old finish or paint. Apply a primer suitable for the material, followed by multiple coats of your selected spray paint. You can use metallic or textured finishes to give the project more character.

Revamping Outdoor Decor

Spruce up your garden or patio with newly painted outdoor decor. Use paint designed for outdoor use, and consider adding a clear topcoat for extra protection against the elements.

Designing Art Pieces

Experiment with different techniques, such as stenciling or layering colors, to produce unique artwork for your home. Wood panels and metal sheets can serve as your canvas.
