Surface Condition
For ideal results, the garage floor must be in sound physical condition, free of extensive cracking, pitting and spalling. The surface must also be dry and clean and free of dust, dirt, efflorescence, oil, chemicals, pevious flaking coatings and other contaminants which may block effective long-term adhesion.

Repairs
For best visual results and long-term performance, cracks, holes and significant surface pitting should be filled with a cement patch material and allowed to cure fully before proceeding.

Expansion Joints
Expansion joints in the concrete slab serve an important purpose, guarding against cracking in the slab due to movement — and should NOT be filled.

Smooth Surfaces
Very smooth or power troweled concrete (often found on garage floors) lacks optimal surface profile for optimal bond. In such cases, etching the concrete is recommended to ensure good penetration and "grab" of the coating. Etching will also remove efflorescence from the surface.

Washing the Surface
Removing all dirt, debris and other contaminants is key for ensuring long term beauty and performance. For easiest and best results cleaning with a pressure washer is highly recommended.

Good surface preparation is easy if performed with attention to a few key details. For best results, follow written product instructions. For more helpful information, a visit to the surface preparation page is also recommended.
