Frost King 350B Polyethylene Sheeting – 3' x 50' x 4 Mil, Black

Overview

Frost King 350B polyethylene sheeting arrives as a sturdy black roll, measuring 3 ft by 50 ft with a 4 mil thickness. The material is designed to help manage ground moisture and create a simple barrier between soil, rock, and the air above. It’s lightweight enough to handle with basic tools, yet thick enough to stand up to outdoor conditions under typical DIY use.

Built for a range of tasks around the home, garden, and garage, this sheet pairs well with decorative rock and gravel to help create clean, weed-controlled beds and display areas. The 4 mil film provides a robust layer that resists tearing and holds its form when laid over uneven ground or across materials that need protection. The black color helps minimize visible wear and blends with many landscape palettes.
