Planter Box Waterproofing Membrane

Waterproofing Coating

Planter boxes are made of different materials; concrete, plastic, metal or wood which serve as raised flower beds. Plastic, metal or wooden planter boxes are generally small and portable, meant for domestic use. Whereas concrete ones are big built-in planter boxes as part of the building. In both cases planter boxes are constantly exposed to standing water, wet soil, fertilizers and of course, regional climate patterns. Regardless of their manufacturing material, they definitely need to be waterproofed before they cause water intrusion to the whole building.

Waterproofing big sized built-in Planter boxes

1. The interior of the planter box should be thoroughly clean and dry. So we need to scrap off all debris, soil or any kind of greasy contaminants.
2. Make sure all the gaps, voids and joints are repaired, filled and sealed to have a smooth, even surface. We need to pay extra attention to the drain assemblies to make them leak proof.
3. Thereafter, we brush primer coatings evenly to fill the minor gaps and ensure proper adhesion.
4. On top of it polyester reinforcing fabric and polypropylene can be laid over the primer layer saturating bottom up. Take care not to make any folds or wrinkles.
5. Membranes must to be flexible, durable and adhesive. The system can only be successful if it is done by an experienced and skillful applicator team following all specifications.

Small, Plastic/Metal/Wooden Planter box Waterproofing

1. Clean and dry the box properly. In order for primer to better cling in, scrub the surface (of wooden planter box) vigorously with a piece of sandpaper.
2. Seal the bottom/wall joints, and all other edges, cracks and joints.Polyurethane or silicon based caulk is recommended for this purpose.
3. Danish oil or an oil based varnish can be used inside or outside (in case of wood), for the UV rays protection,
4. Apply coats of sealant as per manufacturer’s instructions.
5. Avoid air pockets while making brush strokes. Brush/roll it backward or comb the wet surface lightly.
