What is Epoxy?

Epoxy is actually a refinishing product that is used to cover other counter materials to create a high gloss surface that is more durable. You can cover laminate, wood, concrete, or ceramic with epoxy to create a long-lasting countertop with a beautiful shine that will hold up for years to come.

Epoxy is poured over the other material and allowed to set up. It can be a very messy installation process as the epoxy itself comes in a box or a bottle that is then applied according to the manufacturer’s instructions. 

Epoxy products always combine resin and hardener products to create the trademark shine that is associated with these types of counters. Always make sure to read all of the instructions for the epoxy that you have purchased before you begin the installation process.

How to Pour an Epoxy Counter

The process of an epoxy counter installation can be messy and there are some steps that you must always follow to make sure that the end result is as shiny and level as you expected it would be.

Rout Your Corners

Applying epoxy to edges that have not been smoothed will result in a pour that is not smooth and could have bubbles included in it. You will need to make sure that any edges that you are pouring over are smooth.

Fill In Gaps and Seams

Fill in all gaps and seams with an all-purpose body filler. This also includes seams at miters, inside of corners at the front edge, and the gap from where the backsplash used to connect to the counters. It will harden quickly, and you can smooth any burred edges that are left readily.

Sand It Smooth

Smooth any high spots in your filler work with a paint scraper. You will then want to use your 60-grit sandpaper to smooth all surfaces that have required filler. Make sure to sand your rounded corners as well. This will make the epoxy bond better with the counter surface.

Mask Things Off

Epoxy is messy to apply. You will need to tape plastic over the cabinets, the dishwasher and the floors. Make sure that you cover any surfaces that you do not want epoxy to end up on. 

For the sink opening, you will need to tape plastic to the underside of the counter to catch the epoxy as it is poured. You should also put cardboard under the counters to collect any drips that might miss the plastic.

Prepare Your Materials

As soon as you apply the primer coat to the counters, you will need to move fast. Make sure that your materials are ready before you do that first step. Prepare everything that you will need and have it to hand so that you don’t have to stop along the way to find products or mix something.

Applying Primer

Use the paint roller to apply the primer. You will want to pour the two-part primer into a small bucket and then roll it from there onto the counters. If you can see any of the older counter showing through, prime these areas again.

Premix Epoxy

Your primer needs an hour to become tacky. You can mix your epoxy as you get close to the endpoint of the primer’s setting up period. If you are using a metallic powder to create swirls in the mix, stir these up as well in a separate cup. You will have 15 minutes or less to work with the epoxy from here.

Pour on Base Coat

Make sure your epoxy is mixed completely so there are no lumps or dry spots in the bucket. Pour into a second bucket and stir again. Make your first pour of the epoxy down the center of the counter then spread evenly with a roller. Spread to the edges but don’t push the excess puddle off the counter at this point. 

The layer should be 1/8 in thick across the entire counter. If you are adding highlights, do so at this point by pouring over the counter in swirls or thin lines to make veins that look like marble. Use a paintbrush to drag over the stripes to spread them out and make them look more natural.

Spray on Alcohol

Spritz the counter with rubbing alcohol and metallic powder solution. This makes for a natural sparkle that looks like natural stone.

Scrape Drips and Fill Divots

Fill in any divots you see in the countertop surface with leftover epoxy and scrape off the drips that are coming over the edges of the counter surface. Use a stir stick for your scraping process.

You can remove any dust or debris that have invaded the counters with tweezers or a toothpick.
