How to properly prepare a floor for a JetRock epoxy floor installation

 

The preparation of an epoxy floor installation is the most important factor determining performance over its lifespan. 

Here is a break down of how to properly prepare a concrete substrate. Read the Quick Guide to Epoxy Floor Preparation. 

1. Scarifying techniques

Epoxy, as a flooring material, requires a rough surface to form an extremely strong mechanical bond. To achieve the optimal conditions for this to occur, you must thoroughly scarify the surface by either grinding, etching, or shot-blasting the surface.

Grinding

This is the most common method as it is more consistent, less disruptive, and able to access corners, edges, and hard to reach areas.

NOTE: As JetRock has been designed to go directly over existing floors, we exclusively use diamond grinders as it scarifies all surfaces from quarry tile to concrete. We have a shop-vac that attaches to the grinder and sucks up the dust as it grinds.

Etching

Another way to scarify the surface is etching. Acid etching provides smoother indentations compared to other methods. It is often considered the least expensive means yet it can be dangerous, environmentally detrimental, and ineffective if not done properly.

 

Shot blasting

Provides varying levels of coarseness depending on equipment and settings used; usually fastest way to prepare floor yet experience is strongly suggested.

NOTE: Extra care must be taken by installer to prevent stripe pattern from blast impact that could affect overall aesthetics and functionality.

Summarily, some methods have benefits such as time or cost efficiency, consider what method will produce the best results for your specific needs and to ensure your floor replacement will last. 

It is important to note that every space is different and although this will cover the basic concepts of how, what, and why these steps are taken, the process can vary greatly depending on the specific size, scope, and scale of a space.

 

2. Cleaning

Once the floor is thoroughly scarified, the installers will vacuum (with a shopvac) the remaining dust and debris. This is followed by a thorough cleaning. The floor is saturated with warm soapy water and a deck brush is used to agitate the surface. The remaining solution is squeegeed to drains or vacuumed and allowed to dry.

Essentially, by creating the ideal conditions for a mechanical bond between epoxy and the floor you will eliminate the chance that epoxy will bond to loose debris or dust instead.  Do not skimp on preparation or else you will jeopardize the integrity of your new floor. 

Once the floor is scarified, clean and dry, it is ready for the JetRock floor installation.

By taking the time to prepare your floor, you can ensure a lasting bond that will withstand the harshest back-of-house conditions for years to come.
