Plastering Trowel with Teeth Uses 

1. Texturing and Pattern Creation:
   • The teeth or serrations on the trowel are designed to create textures and patterns in the applied plaster or stucco.
   • Common patterns include swirls, waves, or other decorative textures that add visual interest to the finished surface.
2. Keying Plaster:
   • The teeth help to create a textured surface that enhances the bond between the plaster and the substrate, providing better adhesion.
   • This is especially useful in situations where a smooth surface alone might not ensure a strong bond.
3. Creating Grooves:
   • The trowel’s teeth can be used to create grooves or channels in the plaster for functional or aesthetic purposes.
   • Grooves may serve as expansion joints, allowing for movement without cracking, or as a design element.
4. Repair and Patching:
   • Plastering trowels with teeth are handy for repairing or patching existing plasterwork, helping to match textures on repaired areas with the surrounding surface.
5. Artistic Applications:
   • In artistic or decorative plasterwork, these trowels are used to create unique and customized patterns, contributing to the overall design.
6. Creating Non-Slip Surfaces:
   • The teeth on the trowel can be used to create a textured, non-slip surface, which is beneficial in areas prone to wet conditions or where additional grip is needed.
7. Enhancing Durability:
   • By providing texture and keying the plaster to the substrate, the trowel helps improve the durability of the plastered surface over time.
8. Traditional Plastering Techniques:
   • In traditional plastering methods, these trowels are commonly used to achieve specific textures and finishes that may be required for historical or architectural authenticity.
