Abstract
A hand tamper includes a handle and a tamping head. The handle has a cavity to hold a fluid. The tamping head includes apertures in the bottom. Fluid can flow from the handle through the apertures of the tamping head to coat a tamping surface on the bottom of the hand tamper. The fluid can, for example, prevent asphalt from sticking to the tamping head.
