Planter Box Waterproofing
- Surface Preparation:
- Clean and Dry: Remove all dirt, dust, and debris. The surface must be completely dry to ensure the waterproofing bonds properly.
- Repair Defects: Fill visible cracks or gaps with a suitable filler, such as cement grout or wood filler, to create a smooth substrate.
- Sanding (for wood): Use sandpaper (e.g., 200 grit) to smooth out imperfections before applying sealers.
- Drainage and Joint Sealing:
- Install Drainage: Ensure there is a drainage outlet or holes. For larger boxes, a minimum of 25mm diameter holes is recommended.
- Seal Corners: Apply a heavy coat of sealant or polyurethane seal to joints and corners, as these are primary targets for leaks.
- Reinforcement: Embed a waterproof bandage or geo-textile fabric into the wet sealant at corners and joints for added strength.
- First Coat: Apply a continuous, even coat over the entire interior surface using a brush or roller.
- Second Coat: After the first coat has cured properly (usually several hours to a day), apply a second coat to ensure full coverage.
- Height Requirement: Extend the membrane at least 100mm above the expected soil fill level.
