The Crafco Mastic Tank Scraper easily removes excess mastic from your tank

The Crafco mastic tank scraper is a crucial tool designed for the efficient and safe maintenance of a mastic melter-applicator. Its primary purpose is to manage the hot mastic material inside the machine's heated tank, ensuring a clean and consistent operation. The scraper is specifically engineered to handle the unique properties of the hot, high-viscosity, and aggregate-laden mastic without damaging the tank's interior or the agitator's components. Proper use of this tool is essential for preventing material waste, minimizing downtime, and ensuring the quality of the final repair.

One of the most important uses of the scraper is to prevent material from building up and hardening inside the tank. Throughout the day, as hot material is dispensed, a layer can remain stuck to the tank walls, bottom, and around the agitator blades. The scraper is used to break this material free and push it toward the discharge gate for application. This ensures that all heated material is used effectively and prevents the buildup of hardened residue, which can negatively impact the melter's heating efficiency and lead to costly clogs and component damage over time.

The scraper is also a key tool for the end-of-day shutdown and cleaning procedure. Once the day's work is complete, the machine must be thoroughly cleaned to prevent any remaining material from hardening overnight. The scraper is used to systematically clean out the tank, pushing all residual mastic towards the discharge gate to be drained. This ensures that the melter is ready for a quick and efficient startup the next morning, as a tank with hardened material can take hours to heat and clear.

A critical safety note is to never use the scraper while the agitator is running. The agitator's powerful blades can pose a severe safety hazard to the operator and can cause significant damage to the scraper and the machine itself. Operators must always turn off the agitator and the main burner, allowing the machine to cool slightly before inserting the scraper. Adhering to this safety protocol is non-negotiable and protects both the operator and the integrity of the mastic application equipment.
