How to properly prepare your concrete for epoxy

Proper preparation of your concrete for an epoxy coating

Properly preparing your concrete floor for epoxy is serious business, without doing this step absolutely perfect you may have coating failures such as peeling, hot tire pickup or a ruined floor.

This step is not one for the average house painter, it takes a lot of training, knowing and using the products on many projects. Sometimes you have to make quick changes on a job site to deal with surface conditions, access or the unexpected. Without having come across these before there isn't much that can help you.

Typically a diamond grinding or acid etching is needed. These are two totally different processes and each has their up and downsides.

Grinding a surface can be dusty even with the best of equipment, leading to dangerous silica thrown into the air as well as much more cleanup.
Acid etching can simply be dangerous from the fumes and the burns that can occur.

the goal of each is the same, rough up the surface for the coating to adhere to it better.

In recent years even special primers may be used in lieu of these two preparatory processes. Special primers for hard to bond surfaces can and have been used successfully, they are not inexpensive but in comparison to the other ways,they are similar in cost.

We have seen too many times homeowners and contractors take the chance by not prepping the surface due to either cost or laziness and it always ends the same, we come in and see sheets of epoxy that can be just pulled off of the floor.

Taking the time to properly prepare your floor will actually cost less in the future because you will be eliminating the repeated prep or removal of the failed coatings because once it starts to fail it needs to be removed before applying another system on it in many cases.

Once you take the time to do this concrete work and prep you can be assured your epoxy has the correct surface to be applied to and will last for years to come.
