Scarifier

Definition

A scarifier is a piece of thin metal with teeth or serrations cut in the edge, used to roughen fresh mortar or concrete surfaces to achieve a good bond for tiles or other finishes.

Purpose

The purpose of a scarifier is to create a rough texture on mortar or concrete surfaces, improving the adhesion of subsequent layers or finishes.

Examples of Use

• Tile installers use scarifiers to roughen mortar beds for better tile adhesion.
• Concrete workers use scarifiers to prepare surfaces for overlays or coatings.
• Scarifiers are used in road maintenance to roughen surfaces before applying new asphalt.

Related Terms

• Trowel: A tool used to apply and shape mortar or concrete.
• Float: A tool used to smooth and level fresh concrete surfaces.
• Surface Preparation: The process of treating a surface to ensure proper bonding of coatings or finishes.

Notes

Proper use of a scarifier ensures that surfaces are adequately prepared for finishing materials, preventing issues like delamination or poor adhesion.
