Installing epoxy coating over a plywood surface can be done successfully if you know exactly what to do. This article presents two step-by-step guides on how to install epoxy on a plywood surface.

Applying Epoxy Over Plywood

It can be a tricky business to install epoxy over plywood because unlike concrete, plywood usually has a glossy surface. Asides this, plywood is flexible and also unlike concrete substrate, it contracts and expands. This may cause the epoxy you install to crack after some time. But you can avoid these eventualities if you do the right thing.

How To Install Epoxy Over Plywood

The following is one method to install epoxy on plywood:

5 Easy Steps to Install Epoxy Over Plywood

  1. First you have to prepare the surface of the plywood. You have to make it gritty to allow the epoxy to stay on it. You should sand the surface of the plywood with a 40/60 power floor sander. Your aim is to make sure the glossiness of the plywood is totally removed.
  2. As you work the plywood may crack in places. Also there are usually joints in plywood. You need to fix these joints by first applying the epoxy in those joints.
  3. Next, you need a self leveling concrete. Pour the concrete in metal lath.
  4. Add self leveling epoxy in the concrete and mix together.
  5. Apply the mix on the plywood slowly until it is evenly spread.

 

A second method is this:

  1. First apply a light brushing of epoxy on the plywood after sanding. Doing this fills up any holes and prevents air bubbles from developing during the task.
  2. 4 to 10 hours later, pour self leveling epoxy on the dried surface and it will level out.

 

It is important to note that you have to get the time between the seal application and the final application accurately. Epoxy hardens to a very strong consistency. So it is important not to allow the wait to exceed 10 hours. If this happens you will need to sand again.

Conclusion

Epoxy can be installed on many surfaces as long as you understand what to do.oat times you just have to sand down on surfaces. And also to not wait too long before installing the epoxy. And you can apply epoxy several times if you feel the first coat of epoxy is too thin. Allow nothing less than 10 hours to pass before pouring another layer.
