PondMax PondShield 2L Black Waterproofing Paint

PondMax PondShield 2L Black Waterproofing Paint – Pond Sealant

There are four main reliable options for pond construction: fibreglass, EPDM rubber liner, prefabricated hard plastic ponds, or waterproofing paint.

Fibreglass is typically the most long-lasting and solid option, though it can be expensive and requires a professional. We like EPDM rubber (never use plastic liner) and prefab ponds, as they are durable with good warranty periods. Pond paint is a great next-best option, often ideal for smaller projects such as revitalising a fountain or small pond, or sealing water bowls. Our favourite and most recommended pond paint is this one.

The PondMax PondShield Starter 2L is a thick, black membranous sealant designed to protect and seal ponds and water features. Easy to apply and water-resistant, it contains reinforcing fibres to seal fine cracks and provide long-lasting coverage.

Features & Benefits

• Water-resistant, contains reinforcing fibres to seal fine cracks
• Treats up to 2 m² with 2 coats
• Suitable for concrete, brick, stone and timber
• Tough, long-lasting protective membrane

Surface Preparation

Ensure all surfaces are clean, dry and free of dirt, grease, algae, loose paint or rust. Sand old timber surfaces smooth. Porous surfaces may need priming with a diluted mixture (1 part PondShield Starter to 2 parts water), left to dry for 1 hour before applying full coats.

Application Instructions

Allow surfaces to dry completely before applying. Test moisture by taping a clear plastic sheet over the area for 2 hours; if moisture appears underneath, wait until dry. Stir well before use and apply with a brush, roller or soft broom.

Apply in two coats at 0.5L per m² per coat, allowing 24 hours drying between coats, with each wet coat no more than 1mm thick. Apply the second coat at a 90 degree angle to the first for best results. For timber, apply at least 2 coats at a maximum of 1mm per wet coat. For hairline cracks in masonry, prime with diluted PondShield, then fill cracks with PondShield Starter mixed with sand while still tacky, and allow 48 hours to dry before overcoating.
