Proper Cleaning

1. Immediate Cleaning: Always clean your trowel immediately after use to prevent plaster from hardening on the blade. Use a bucket of clean water and a sponge or brush to remove any leftover material.
2. Scraping: For stubborn residues, use a plastic scraper rather than a metal one to avoid scratching the surface.

Storage

1. Dry Storage: Store your trowel in a dry place to prevent rusting. Moist conditions can deteriorate the metal blade over time.
2. Protect the Blade: Use a blade guard or sheath to protect the trowel when it’s not in use.

Maintenance

1. Regular Inspection: Periodically check the trowel for any signs of wear, such as nicks, warping, or corrosion.
2. Oil the Blade: A light coat of oil can help protect the metal from moisture and rust. Use a lint-free cloth to apply and wipe off excess oil.
3. Tighten Screws: Ensure that the screws connecting the handle to the blade are tight. Loose screws can result in uneven application and can damage the trowel over time.

Proper Usage

1. Right Pressure: Don’t apply excessive pressure while using the trowel; this can lead to premature wear and bending of the blade.
2. Use the Right Trowel for the Right Job: Plastering trowels come in different shapes and sizes for specific tasks. Using the correct type will help prolong its lifespan.

Protective Measures

1. Handle with Care: While cork handles are durable, it’s good to avoid dropping the trowel as it can affect the alignment and even crack the handle.
2. Avoid Prying: Never use your plastering trowel as a pry bar or hammer. This can severely damage the blade and handle.
