Today is all about chemist tips on spray paint!
Spray is by far one of my favorite tools to use for just about everything! One of the best chemical inventions of all time!
And as a chemist, I have researched many things about it including how it works. I was recently approached for an interview regarding scientific facts about spray paint, and it inspired me to do a post on the blog!
First, what is spray paint? Spray paint is a combination of paint and gas propellant. The propellant used to be CFC (or Chlorofluorocarbons), but was banned due to the damaging effects on the environment. Now, most spray paints use hydroflourocarbons, made of hydrogen, flouride, and carbon. So, spray paint is no longer hazardous to the environment like it once was.
I don’t know about you, but I always like to get the most out of a can. Spray paint isn’t necessarily expensive, but it does add up! Here are my tips and tricks for spray paint:
1. Expensive spray paint doesn’t always matter!
I have used just about every brand of spray paint on the market. In short, expensive spray paints go much further because they are typically higher in paint concentrate. That doesn’t always matter though! If I am doing a project that requires very little spray paint, like a frame or a small box, I buy cheap! If I am doing an outdoor project or one that will require a large area to be covered, I will buy a better quality simply because it will last longer.
2. Always use short strokes!
Meaning, use short controlled sprays instead of just spraying down the entire time. Since spray paint is made with gas propellant, you will waste more paint by holding down the spray nozzle the entire time. It may go faster, but I would rather get the most out of a can. I always do short quick strokes. This also avoids dripping and concentrated areas of paint.
3. The best spray paint tool EVER!
This Standard Spray Grip tool is a MUST HAVE. It is so inexpensive, plus it will keep your hand clean and free from pain. As you know from my previous posts, I have RA which hinders my ability to grip well. This tool saves the day every time!
4. Mix colors!
I don’t always find the right shade I am looking for, so many times I will buy a good quality base shade and cover an item with that. Then, I will follow up with a cheap gold spray paint and lightly spray over that to create a pretty two toned color. Most projects I get the most compliments on are ones I have mixed colors with.
My favorite mixes: Rust-Oleum Bright Gold with Rust-Oleum Kona Brown. These two together makes this beautiful, almost bronze color. Many of the colors in my home are a goldish bronze, but I could never find a color that matched it. This combination comes very close. To create this, I first color the item with brown. After it dries, I lightly spray the gold over it. It creates a color like the one shown below.
5. Always use a top coat!
I used to never use a top coat, until I did some research years ago regarding paint preservation on certain surfaces. I realized that I needed to start using it!
To avoid paint rubbing off, or smelling like spray paint in your house, use a top coat of some kind. This keeps the paint protected and sealed. Especially if you are painting wood. Spray paint soaks into wood and rubs off more than other surfaces, so it can wear off quicker.
