Dusting

Definition

The application of dry portland cement to a wet floor or deck mortar surface, forming a pure coat by suction of the dry cement.

Purpose

Dusting is used to create a hard, durable surface on concrete floors or decks. This method enhances the strength and wear resistance of the surface, making it suitable for high-traffic or heavy-use areas.

Examples of Use

1. Industrial Floors: Applying dry cement to wet concrete surfaces to increase durability.
2. Garage Floors: Strengthening the surface to withstand vehicle traffic and wear.
3. Patios and Decks: Providing a durable finish for outdoor concrete surfaces.

Related Terms

• Topping: Applying a thin layer of concrete or mortar over an existing surface to improve its properties.
• Concrete Finishing: The process of creating a smooth, hard surface on concrete by various methods.
• Surface Hardener: A material applied to concrete to increase its surface hardness and durability.

Notes

• Proper application techniques are essential to ensure a uniform and durable finish.
• The timing of the dusting process is critical; it must be done while the surface is still wet enough to absorb the dry cement.
