These epoxy resin coatings are perfect for numerous projects
Which epoxy resin coatings are best?
Epoxy resin coatings are versatile and protective. They provide strength for numerous uses that adhesives and glues can’t match. That’s why these superior coatings are popular in industrial, construction, marine and creative applications when a durable, long-lasting coating is required.
It takes proper instructions and a little skill to mix and apply an epoxy resin coating properly. It also requires knowledge about this type of product to choose one that will match your needs. Our buying guide has you covered with everything you need to know about epoxy resin coatings plus a roundup of the best products on the market.
Why use epoxy resin coating?
There are many finishes available, from paints and varnishes to powder coatings, but none offer the combination of visual quality, hardness and ease of use. Most varnishes, though simple to apply, are neither particularly hard nor durable in extremes. Powder coating is very tough — it’s actually a form of epoxy — but requires baking in an industrial process, which is often impractical.
Epoxy resin coatings are a two-part mix — synthetic polymer (resin) plus hardener. They combine ease of application (via brush, roller, pad, or pour) with immense strength once cured properly. Epoxies also have numerous creative applications which can be interesting to explore.
Features of epoxy resin coatings
Clarity: For many uses, clarity is important. You should look for UV protection — which prevents yellowing in sunlight — but the effectiveness can be difficult to judge without experimentation and time to assess any change. It’s worth checking customer reviews to get a good idea of the actual clarity.
Chemistry: There are aspects of the chemistry that will have an impact on your choice. In particular, the chemistry of an epoxy resin coating impacts the curing time and temperature demands. While it’s not unheard of for epoxies to harden overnight, some can take several days — and the environment may need to be controlled to some extent.
Mixing: In order to make an epoxy resin coating, the first step requires mixing the resin and hardener together. Most formulas require equal parts or a 1:1 ratio. However, some epoxies must be mixed using a 2:1 ratio for them to cure properly. Each product includes instructions that will indicate the mixing ratio. Keep in mind that it’s important to follow the directions precisely for the components to turn into an epoxy that cures and produces a clear, bubble-free finish that’s hard and long-lasting.
Application: Workability is another aspect to consider. Technically, the two components in epoxy resin coatings start to harden as soon as they are mixed, but an “open time” is usually listed by the manufacturer during which they stay fairly liquid. This is vital for surfaces like countertops and other large areas so you have time to cover the whole surface uniformly. There are also self-leveling products, but they only help to a degree, mostly by filling in marks from your brush or other tools.
While larger bottles of course cover greater areas, one-gallon packs from different manufacturers won’t necessarily provide the same coverage. Expected coverage should be provided, usually in square feet at a specified thickness.
If you’re using epoxy resin coating for creative purposes, you may want to check for compatible pigments and whether it’s suitable for molding — there are often limits to size or thickness (although it may be possible to build up multiple layers).
Smell: Some epoxy resin coatings can give off an unpleasant smell, so you might want to look for one known for its low odor.
