When Does a Concrete Floor Need an Epoxy Primer?
Primer choice depends on the substrate and the coating system.
What primers do
A specified primer may help wet the prepared substrate and support adhesion, but it does not repair weak concrete or eliminate moisture.
Not always the same product
Some systems require a dedicated primer; others use a designated base coat. Follow the approved sequence rather than adding arbitrary layers.
Check recoat windows
Confirm preparation, application rate and the time allowed before the next layer.
Plan your project
Browse the available systems and products. Always check the manufacturer’s technical data before selecting an application method.
