How to prepare a wood substrate for epoxy floor installation

JetRock is designed for installation directly over the existing floor. There are specific steps that vary depending on the condition and type of existing floor present to ensure the lasting success of the floor.


A wood floor (in acceptable condition) requires the least amount of preparation compared to other existing floors due to its natural ability to form a very strong bond with epoxy. The greatest concern is that the existing floor is in stable enough shape to install over. The preparation prior to installation is incredibly important to the longevity and performance of the JetRock flooring system.

Here is how the Feature Flooring team prepares a wood floor.

Assess condition of the floor

Epoxy is able to form a strong bond with wood with little preparation. When installing a JetRock floor, the most important factor is the soundness of the existing floor. If there is any sign the floor has water damage or is rotting, it will need to be replaced prior to installation.


By sweeping or vacuuming loose dirt and debris, the epoxy is able to bond directly to the wood as opposed to whatever remains on the surface.

Fill Seams

The JetRock flooring system is a hand-troweled system that follows the natural contours of the existing floor. As a result, the seams, joints, or indents must be painted (or filled) with a resin-rich epoxy and grout mix that is able to fill the seams and result in an even surface. If the JetRock floor is placed directly over seams and joints from floor boards, the mixture will seap into seams and could result in visible lines following the application.

Allow Epoxy Fill to Cure

Once the epoxy used in seams is cured (about 1.5 hours), it is ready for the JetRock cove base and flooring application resulting in a fully integrated, seamless, watertight, and slip-resistant flooring solution that will last through the harshest conditions.
