Burlap Rub

Definition

A burlap rub is a finish obtained by rubbing burlap to remove surface irregularities from concrete.

Purpose

The burlap rub technique is used to smooth and refine the surface of concrete after it has partially set. This process enhances the aesthetic appearance of the concrete and helps to remove minor surface imperfections.

Examples of Use

1. Concrete Walls: Applying a burlap rub to exposed concrete walls to achieve a smoother and more uniform surface.
2. Columns and Beams: Finishing concrete structural elements with a burlap rub to improve their visual appeal.
3. Architectural Concrete: Using burlap rub on decorative concrete surfaces to achieve the desired texture and finish.

• Sacking: A technique where a cement grout is applied to the concrete surface and then rubbed with a burlap sack to fill in voids and imperfections.

Notes

The timing of the burlap rub is crucial for achieving the best results. It should be performed when the concrete is firm enough to withstand rubbing but not fully hardened.
