how to build epoxy countertops?

Epoxy resin countertops are the perfect choice for any kitchen, bathroom, or bar. They are durable, stain-resistant, and easy to clean.

You can buy epoxy kits at home improvement stores and install them yourself, but if you want a higher quality product then it is better to have them professionally installed.

Here’s everything you need to know about how to install an epoxy countertop:

How do I make my own epoxy countertop?

Epoxy countertops can be made at home, and the process is pretty simple. The first step is to buy your epoxy resin, hardener, and wood (plywood or MDF).

You’ll also need tools for cutting the wood: a table saw to cut plywood into sheets, and a router if you want to do an edge treatment.

Next, mix up the epoxy. If you’re using a five-gallon bucket as your mixing container like I did here in my garage workshop then don’t worry about mixing cups; just use what comes with each kit of resin/hardener.

What kind of wood do you use for epoxy countertops?

You can use any hardwood plywood to build your epoxy countertops, but some are better than others. The best plywood for epoxy is marine-grade plywood, which has a waterproof coating on one side of the wood.

It’s often made with fir or poplar and is used in boat building because it is strong and durable.

When you buy your wood at a home improvement store, ask them what kind of wood they have available. If they don’t have marine-grade plywood, try to find someone who does—it will be worth it!

How much does it cost to make an epoxy countertop?

The cost of making an epoxy countertop depends on the size and thickness of the countertop, as well as what type of wood is used.

For example, a 4-foot by 8-foot sink cutout will cost more than a similar sink cutout in plywood because it’s made from hardwood instead of softwood.

Another way to determine how much an epoxy countertop will cost is by figuring out how many square feet you want covering with epoxy resin (1 gallon covers about 100 square feet), then multiplying that number by $2 per gallon.

For example: If you want to cover 400 square feet with epoxy resin, multiply 400 x $2 = $800 total cost for your project!

Why You Should not Do epoxy resin countertops?

Epoxy resin countertops are not easy to install.

Preparing the surface is a time-consuming and messy process, as you will need to clean off all dirt and debris from your countertop before applying the epoxy.

Epoxy resin countertops are not easy to repair.

The surface of an epoxy resin countertop may become damaged over time if it is scratched or scuffed too much, but repairing such damage can be difficult because performing repairs will require sanding off a portion of the top layer and then re-applying more epoxy resin onto that area—an undertaking which requires enough patience and skill (or lots of help) that few would choose this option instead of simply replacing their entire kitchen’s cabinets with new ones!

How thick should epoxy countertop be?

The thickness of the epoxy countertop depends on the look you want. Thinner epoxies will be easier to cut and more flexible.

Thicker epoxies are more rigid and can support weight better, but they’re also more expensive. One inch (1″) is a good thickness for most people; if you want thicker countertops, choose 1-1/2″ or even 2″.

Many people who use thick spacers between their stone tile and the epoxy say they wish they had gone with a thinner layer of epoxy instead so that there would be less gap between their tiles and the concrete slab underneath them.

If this sounds like something that would bother you, then consider going with a thinner coating than we recommend here: our own preference is 1/2″ thick by default because it’s affordable yet still leaves plenty of room for error when laying tile down on top later!

How long do epoxy countertops last?

Epoxy countertops can last for decades. The material is resistant to scratches, heat, chemicals, and water stains. It’s also very easy to clean—just wipe off any spills with a wet cloth or sponge and let it dry overnight.

Epoxy countertops are made from the same materials you find in your car windshields (e.g., epoxies), so they do have some similarities in their composition: Both contain oil that will trap dirt and debris within its surface if you don’t clean them regularly.

Can I epoxy over plywood?

The short answer is no, you can’t use plywood. Plywood is too thin to be used as countertops and will warp or crack after being coated with epoxy.

The longer answer: Plywood is intended for furniture and other projects where it can be completely hidden, like behind a cabinet door or inside of a drawer.

It’s not meant to be exposed on an open countertop. If you’re building a piece that needs support, then there are many other materials that would work better than plywood: OSB (oriented strand board), particleboard and even PVC boards could all be used instead of plywood since they are stronger and more durable while still having the same structural integrity as your original planks.

You’d want something with at least 1/2″ thickness so that when you cut it down into 2x4s they’ll still have enough mass in them so they don’t buckle under their own weight over time when exposed at all times like this project does!

Will epoxy countertops yellow?

Yes. Epoxy countertops will yellow over time, but that’s okay! The good news is that epoxy countertops are so durable that they’re likely to last for years (even decades) before they start to show signs of wear and tear.

In fact, it’s not uncommon for homeowners to have their epoxy countertops in place for 15 or more years before any discoloration takes place.

However, if you’re looking for a long-lasting kitchen remodel project with minimal upkeep required down the line, then epoxy might not be your best bet.

The reason being? Over time the ultraviolet rays from sunlight can damage the coating on your countertop—and once it starts to fade away or deteriorate entirely (which will happen eventually), then you’ll need to replace it sooner rather than later.


Epoxy countertops are a popular choice for many people because they are easy to install and durable. However, there are some drawbacks to consider before you make this decision.
