The Most Dangerous Playground I've Ever Built
What happens here
After the stain has dried, the creator applies Flex Seal Liquid (clear) to waterproof the entire structure. He explains that Flex Seal is a rubberized sealant that protects against rain, snow, sun, and UV degradation, and will also provide grip for climbing. He pours the Flex Seal into a paint tray and applies it using both a roller and a brush to ensure full coverage on all surfaces, including the top and inside areas.
Goal: Waterproof the stained wooden structure for long-lasting outdoor use.
