Up until recently, the idea of an epoxy spray paint has been a thing of fiction. Of course, this hasn’t stopped numerous brands from cashing in on the popularity that epoxy and epoxy products have gained in the past few years. Big companies are all to happy to put a name like ‘epoxy’ on one of their products, even if that isn’t quite true. For the most part, these sprays behave in ways that mimic the best qualities of epoxy. But in the end they are nothing more than spray paints that stay waterproof for… a while.
The thing is, epoxy must be mixed prior to application. You can’t exactly have a true epoxy paint in an aerosol can and expect anything to come out after more than a few minutes. The epoxy would cure in the can, and you’d be stuck with cylindrical paper weight.
So, what has happened recently, and what do you need to be aware of? Well, technology has progressed, as tends to happen, and we now have a number of aerosol cans that handle mixing just prior to spraying. Rust-oluem’s new spray includes a can with a rather ingenious method to mix the resin with the hardener. Releasing the hardener into the resin/paint is handled via a plunger that one inserts into a narrow tube at the base of the can. Now, as you might expect, you can’t exactly spray a little bit, put the can on a shelf in the garage, and come back out the following weekend to finish your painting project. But that’s a good thing. Once the hardener is released, the paint begins to cure, which is one of our definitive characteristics of all epoxies.
There is also a product from Rubber-Seal available, though I can’t provide as much commentary on this one, as it is a paint that I have yet to try. But, in the end, there is one thing that you need to remember first and foremost before making any kind of epoxy spray paint purchase. When you’re in the store shopping, look at the can and pay special attention for an indication that there are two parts within that require mixing. Because as we discussed in “What is Epoxy?,” epoxy is a two part compound that cures when mixed together. A plunger, like you’ll find on the Rust-oleum can, or some other apparatus should be visible that will be your hint that the product in your hands is an actual epoxy, and not just a large company praying on overly-trusting consumers.
You’re going to want a good quality, actual epoxy for use on your home. If you have insurance with a company such as Aviva, you probably understand the importance of looking after your home. Make sure you are extra careful when buying epoxy, so you don’t end up with an imitation.
