For some hobbyists and DIYers out there, one material that you’ve probably tried using is spray paint. I’ve had my share of boo-boos when using a can of spray paint that ever since then I’ve always paid attention to the nitty gritty details.

Now this how-to covers the most common of instructions using a can of aerosol-propelled spray paint. I know some serious hobbyists have invested in compressors and spray guns, and I believe that they already know what they’re doing. So this is more for the ordinary folks out there who’d like to spray paint.

Now there are quite a number of factors that you’d have to consider in spray painting. But more or less, here are the common steps and pointers on spray painting before giving your project a go.

1. Type of paint

   Consider what kind of surface you’d be painting on. There are basically two-types of paints latex and oil-based. Most spray paints I’ve used are lacquer acrylics which I use for most projects (Never use it for styros though, lacquer eats it up!). For more paint type FAQs, you can check here and here. Or you can consult your friendly neighborhood hardware or paintshop.

2. Prepare the surface

   Make sure your surface is clean, dry, sanded, and primed. Well, this depends on your surface. Some may not need sanding and priming.

3. Mask off other surfaces

   Make sure you mask off the other surfaces using layers of newspaper and masking tape. Make sure your tape is neat and conforms to surfaces. You don’t a want noticeable uneven patch of paint standing out.

4. Read the instructions

   Read the instructions on the can. You’d probably see warnings like “Flammable” or “Don’t use for surfaces such as…” Make sure you follow them.

5. Protect yourself

   Safety first! It’s best to work in protective overalls, a mask (so you won’t inhale the fumes) and goggles. Better work in a well-ventilated area.

6. Shake the can

   Shaking the can mixes the pigment inside the can that may have settled during storage. There’s a mixing ball inside the can that’s why there’s this rattling sound when you shake it. Make sure to shake it a bit more than what’s written in the instructions.

7. Test on a sheet of newspaper

   Practice spraying on a sheet of newspaper to make sure that the nozzle spray mechanism works. You should see a fine mist when you start spraying.

8. Test on the surface

   Find a discrete spot on the surface and test the paint out. Some surfaces may not react too well with the paint. It’s better to find out sooner than after you’ve finished with the painting.

9. Spray

   Check the distance as indicated by the can instructions. Spray evenly and quickly moving the can up-down and side-to-side direction. Go an inch over the edges (hence the need for masking). In most cases, it’s better to spray thin coats in 15 minute intervals. Shake the can and test spray before each go.

10. Let dry

    Leave the surface to dry for the instructed length of time.

11. Touch up

    If you need to touch up or sand-finish the paint do so after the paint has fully dried.
