Can I Brush On Epoxy Resin?

Applying epoxy resin correctly is a crucial step in the application process. Failing to apply epoxy properly will not only prolong the curing time but can affect the entire item’s quality. In order to achieve the best possible epoxy finish, it’s essential that you use the correct materials. If you’ve been asking yourself the question, “Can I brush on epoxy resin?” you have come to the right place to find the answer.

In short, foam roller brushes work best for applying epoxy resin. This is primarily due to the uneven application that can occur when brushing on epoxy resin with a bristle brush. Oftentimes, the bristles will weigh down with the resin, leading to an uneven coat.

While it is possible to use a brush for applying epoxy resin, foam brushes and rollers work best during the application process. If you’re still unsure how to effectively apply epoxy resin, have no worries! In this article, we’ll walk you through a step-by-step guide for applying epoxy products using a foam roller brush.

Can Epoxy Resin be Applied with a Brush?

Using proper materials is essential for achieving the glossy appearance epoxy resin is admired for. Because an uneven coat will affect the epoxy finish, it’s important to carefully apply the epoxy resin with an appropriate brush. If you’re struggling to decide whether to use a bristle brush or foam brush, consider how a brush affects your epoxy products.

Generally, foam roller brushes are recommended for applying epoxy resin. Because bristle brushes can become weighed down by the resin, an uneven coat may occur during the application process. Foam brushes, on the other hand, smoothly apply epoxy for a glossy, even finish.

A squeegee also works well for applying epoxy resin to products. To increase the polished appearance of epoxy pieces, consider using a squeegee along with your foam roller. This will promote a smooth coat while preventing any bubbles from forming.

If you decide to use a bristle brush, it’s extremely important that the brush is fresh and clean. Before pouring the epoxy, use a piece of tape to remove any loose fibers or debris on the brush. Bristle brushes work best for projects that require sanding between applications. For the last coat, it is best to use a foam brush to ensure an even surface.

How to Apply Epoxy Resin

When using the correct tools, applying epoxy resin can be a relatively easy process. Whether you’re working with large epoxy flooring, or you’re crafting small jewelry pieces, spreading a coat of epoxy is an easy project for both the beginner and the expert. Here, we’ll walk you through everything you need to know about applying epoxy resin to a variety of surfaces.

Prepare the Epoxy Resin

Mixing the epoxy resin is the first step towards application. Epoxy consists of two parts: resin and hardener. When these two elements are combined, a chemical reaction will cause the liquid ingredients to become solid material. In order for epoxy to apply smoothly, the mixture must be precise. Using the incorrect mixing ratio will result in uneven surfaces or a prolonged curing time.

Because every mixture is different, it’s important to always follow the manufacturer’s instructions written on the epoxy’s label. Most epoxy resins require a 1:1 or 2:1 mixing ratio. To mix the elements, use a flat spatula similar to a paint stirrer to gently stir the resin. Another method is to use two buckets for pouring epoxy resin back and forth. After pouring it several times, mix the epoxy with a spatula.

Before working with epoxy resin, make sure you are wearing protective clothing. Items such as safety gloves and goggles are essential, especially when working with epoxy indoors.

Applying the Epoxy Resin

Once you have gathered your tools and carefully mixed the epoxy, the next step is applying it to your products. Begin by pouring the epoxy on the center of your project. From here, spread a thin layer of epoxy across the surface using either a foam roller or squeegee. To ensure an even coat, consider using the “W” method for spreading epoxy resin.

Depending on the type of project you’re working with, you may find yourself dealing with edges. Edges are typically more difficult to paint, since they may lead to dripping. If you’re worried about the epoxy running over the edge of your piece, use tape for catching the drips. To paint the edges, use either a foam brush or the tip of your finger to gently spread the epoxy. As previously mentioned, always wear latex gloves when working with epoxy. 

Apply a Second Coat of Epoxy

Once the epoxy has had time to cure, you will likely want to apply a second coat. A second coat increases the glassy appearance while protecting the surface from damage. For many projects, multiple layers are desired, particularly when working with art pieces or epoxy furniture.

Before sanding down the surface for a second coat, allow the initial coat of epoxy to cure for at least 24 hours. The curing process may take longer in some projects, especially if you applied it in thick layers. Once the epoxy is dry to the touch, use high grit sandpaper for smoothing out the surface. Remove any debris or residue with a cloth before continuing on with applying subsequent coats.

Applying the second layer of epoxy is similar to applying the first coat. Using a foam roller or squeegee, spread a thin layer of epoxy across the surface. Once again, consider using the “W” method, which applies the epoxy in a criss-cross manner. If you plan on applying more layers, allow the epoxy to dry before sanding down the surface again.

Apply Epoxy Resin at the Correct Temperature

Applying epoxy resin at the correct temperature is crucial for ensuring a smooth, uniform layer. For best results, keep the temperature between 75 to 85°F during application. Temperatures too low or with too high of humidity can significantly affect the epoxy’s ability to cure.

We hope this guide helped answer any questions you had about applying epoxy resin to projects. By using the right tools, you can rest assured your epoxy products will maintain their glossy appearance for years to come.
