DIY Epoxy Countertops Made Easy: A Complete Guide for Beginners

If you’re looking for a cost-effective way to upgrade your worn countertops, DIY Epoxy Countertops are the way to go. This coating will make your countertops look amazing while increasing their resistance to scratches, chipping, and stains. For example, Jane, a DIY enthusiast, transformed her outdated kitchen countertops into stunning epoxy surfaces, saving over $2000 compared to professional installation costs. Epoxy countertops offer unparalleled customization options, allowing you to create designs that perfectly match your home’s décor.

Different Types of Countertop Materials

There are many different types of countertop materials on the market that you can purchase to upgrade the existing countertops in your kitchen, bathroom, or laundry. These include:

• Granite countertops: Durable but expensive and difficult to install.
• Engineered stone countertops: Cost-effective and easier to install than natural stone.
• Concrete countertops: Customizable but require sealing.
• Marble countertops: Luxurious and elegant but prone to staining.
• Bamboo countertops: Eco-friendly but less durable.
• Hardwood countertops: Warm and classic but require maintenance.
• Butcherblock countertops: Great for food prep but can show cuts and stains.
• Reclaimed wood countertops: Sustainable and unique but may need extra treatment.
• Stainless steel countertops: Perfect for modern kitchens but can dent and scratch.
• Laminate countertops: Affordable and easy to install but less durable.
• Tile countertops: Customizable but grout lines can be hard to clean.
• Recycled glass countertops: Eco-friendly and stylish but can be expensive.
• Synthetic solid surface countertops: Seamless and easy to repair but can be less heat resistant.

Epoxy resin stands out due to its versatility, durability, and ability to adhere to almost any surface. Unlike granite and marble, epoxy can be customized with colors, patterns, and embedded objects to create unique designs. For instance, a homeowner in Texas embedded seashells and sand into their epoxy countertop, creating a personalized beach-themed kitchen.

Tools & Materials you’ll need for Making DIY Epoxy Countertops

One good thing about making an epoxy countertop is that you don’t need a lot of tools. Surprisingly, you probably have some of these tools in your workshop already.

Let’s look at the things you will need to get started with your DIY Epoxy Countertops project. Here’s why each item is essential:

Tools

• An oscillating tool: For precise cutting and sanding in tight spaces.
• Orbital sander: To smooth the surface for better epoxy adhesion.
• Brushes: For applying primer and topcoat.
• 6” paint roller: For spreading epoxy evenly.
• Drill and drill bits: To prepare surfaces and mix epoxy.
• Trim router: To create smooth, rounded edges.
• Heat gun: To remove air bubbles from the epoxy.
• Respirator & Safety Glasses: To protect from fumes and dust.

Materials

• Primer & hardener: Seals the surface and provides a smooth, non-porous base that improves the adhesion of the epoxy resin.
• Epoxy resin & hardener: The main components of your countertop, creating a durable, glossy, and heat-resistant surface.
• Stirring sticks: To mix the epoxy resin and hardener thoroughly to ensure a proper chemical reaction.
• Topcoat & hardener: Provides an additional protective layer over the epoxy resin, enhancing durability and gloss.
• Plastic sheet: Protects the surrounding areas from spills and drips during the epoxy application.
• 60, 80 & 220-grit sanding pads: Different grits are used for various stages of surface preparation and finishing.
• Spray bottle: Useful for misting surfaces to help with cleaning or for applying certain additives.
• Painter’s tape: Masks off areas that should not be covered with epoxy and helps create clean edges.
• 4 x 1-quartz measuring cups: Used for measuring out precise amounts of resin, hardener, and additives.
• 2 x 2-gallon buckets: Large containers for mixing larger batches of epoxy resin and hardener.
• 2 x paddle mixers: Attach to a drill for thorough mixing of resin and hardener in large quantities.
• Wiping cloths: Clean up spills, wipe surfaces, and remove dust.
• Microfiber cloth: For final cleaning and polishing of the cured epoxy surface.
• Polishing compound: Enhances the gloss and smoothness of the epoxy surface.
• Nitrile gloves: Protect your hands from the chemicals in epoxy resin and hardener.

Surface Preparation for Your Old Countertops

Before you start your epoxy project, you need to prepare the surface of your old countertop. Follow these detailed steps to ensure the best results:

1. Remove The Backsplash: This adds extra work but provides a seamless finish. Use a carbide blade and oscillating tool to cut and remove the backsplash until it’s flush with the rest of your counter. Fill gaps with a sawdust and wood glue mixture, let it dry, and sand it flat.
2. Remove The Sink: This allows for easier epoxy application and protects the sink from being sealed. Carefully tape the counter and reach tight areas.
3. Rout The Corners: Epoxy runs off sharp edges, so use a router with a 3/8” or ¼” round-over bit to create rounded corners. This ensures the epoxy flows and bonds well.
4. Fill In Any Gaps: Use a multi-purpose body filler to fill seams and gaps. Mix the filler components quickly as they harden fast.
5. Sand The Countertop Surface: Use a paint scraper and 60-grit sandpaper to smooth the surface and rounded corners.
6. Clean The Old Countertop Surface: Thoroughly clean to remove dirt and dust, preventing them from being sealed into the epoxy.
7. Protect The Surrounding Floors And Furniture: Tape plastic sheeting over floors and mask walls near the counter. Add a wooden barrier around your countertop to contain the epoxy.
8. Prepare Your Materials: Ensure all necessary materials are within reach before starting.
9. Prime The Surface: Mix a 2-part primer and apply it with a brush/roller. If the old counter pattern/color is still visible, apply more primer. Let it cure for 24 hours, then sand with 120-grit sandpaper.

Steps for Applying Epoxy Resin to the Old Countertop

Once you’ve prepared the countertop surface and gathered all your essential equipment, it’s time to start the coating process.

1. Use Safety Equipment: Wear disposable nitrile gloves, old work clothes, a respirator mask, and safety goggles to protect yourself from epoxy fumes and spills.
2. Choose A Design: Decide on a clear or colored epoxy finish. For example, you can mix different colors to create a marbled effect or embed decorative items for a unique look.
3. Mix Your Resin And Hardener: Measure equal amounts of resin and hardener, considering the dimensions of your countertop. Mix slowly with a stirring stick to avoid bubbles. If using pigments, mix them in separate containers for consistent colors.
4. Apply A Thin Epoxy Layer: Pour a thin layer down the center of the countertop and spread it evenly with a roller. This base coat reduces bubbles.
5. Roll The Edges: Pour leftover mix along the edges and use a saturated roller sleeve to spread it evenly.
6. Remove Air Bubbles: Use a butane torch or heat gun to gently move over the wet resin surface and remove bubbles. Ensure your butane torch is full before starting.
7. Allow The First Layer To Cure: Let the first layer harden for 4 to 20 hours, depending on the manufacturer’s instructions.
8. Apply The Second Layer: Use the same pouring technique as the first layer, ensuring both layers have a uniform thickness of about 1/8”. Use a scraper to smooth the surface.
9. Leave The Epoxy To Cure: Allow the second layer to cure for 24 hours to the touch and 2-3 days for full curing.
10. Finish Your Countertop: Remove painter’s tape, sand off drips with 120-grit sandpaper, and apply 4-5 layers of polyurethane for durability. Let each layer dry before applying the next. Allow the surface to cure for another 5 days before use.

Conclusion

Making DIY Epoxy Countertops is one of the most cost-effective ways to transform your bathroom and kitchen. If you feel like making one yourself, follow the steps I’ve listed above. But if the task feels like too much, hire a professional to install one for you.
