What is Rush Coat and How to Apply Rush Coat
When it comes to enhancing the durability and aesthetics of concrete surfaces, rush coats play a vital role.

What is a Rush Coat?
Understanding Rush Coat
Rush coat is a protective layer applied to the surface of concrete or masonry structures. It is typically a mixture of cement, sand, and water, sometimes enhanced with additives to improve its performance. The primary purpose of a rush coat is to provide a smooth, durable, and visually appealing finish to concrete surfaces.
Why Use a Rush Coat?
Rush coat serves several purposes:
- Protection: It shields the underlying concrete from environmental factors like moisture, chemicals, and physical wear.
- Aesthetics: It provides a uniform and smooth surface, improving the visual appeal of the structure.
- Bonding: It enhances the bond between the old and new layers of concrete, especially in repair and renovation projects.
How to Apply Rush Coat
- Preparation of the Surface
Before applying a rush coat, proper surface preparation is crucial. Ensure that the surface is clean, dry, and free from dust, grease, or any loose particles. Any existing cracks or imperfections should be repaired to ensure a smooth application.
- Mixing the Rush Coat
Prepare the rush coat mixture by combining cement, sand, and water in the correct proportions. The typical ratio is one part cement to three parts sand, with enough water to achieve a workable consistency. For enhanced performance, you may add bonding agents or plasticizers as recommended.
- Application Process
- Application: Using a trowel or a brush, apply the rush coat evenly across the surface. Start from one end and work your way to the other, ensuring consistent coverage.
- Smoothing: After application, smooth the surface with a float or trowel to remove any trowel marks and achieve a level finish.
- Curing: Allow the rush coat to cure properly. This usually involves keeping the surface moist for a specified period to prevent cracks and ensure proper bonding.
- Final Touches
Once the rush coat has dried, inspect the surface for any imperfections. Any minor issues can be corrected with additional touch-ups to ensure a flawless finish.
