Staal & Plast polystyrene adhesive – for EBB & Flow trays

Staal & Plast Polystyrene Glue is a professional adhesive developed specifically for assembling, extending and repairing EBB & Flow trays made from high-impact polystyrene (HIPS). The formula is made from the same material used to manufacture Staal & Plast trays, ensuring an exceptionally strong, waterproof and long-lasting bond between individual elements. It is suitable for both new installations and repairs to professional irrigation systems.

Staal & Plast polystyrene glue is specially developed for the manufacturer's professional EBB & Flow systems and guarantees reliable, durable bonding of individual trays. Unlike universal adhesives, it contains high-impact polystyrene (HIPS), identical to the material used to manufacture the trays themselves. This allows the materials to bond virtually as one, providing a strong, watertight joint.

When building large EBB & Flow tables, the manufacturer recommends initially fixing the trays with hot-melt glue for correct positioning and to maintain the required installation joint. The polystyrene glue is then used to permanently bond the individual trays together, providing a strong connection.

The adhesive is suitable for both new installations and repairing damaged trays. Once fully cured, it forms a strong, durable bond that withstands constant contact with water, nutrient solutions and the usual conditions in greenhouses and professional production facilities.

The manufacturer recommends applying the adhesive evenly and sparingly. Excessive amounts can damage the trays, and such damage is not covered by the warranty.

📋 Instructions for use

1. Position the trays and leave the recommended installation joint.
2. Temporarily secure them with hot-melt adhesive if necessary.
3. Apply an even layer of polystyrene adhesive along the entire length of the joint.
4. Allow the adhesive to cure for 48–72 hours at a temperature of around 20°C.
5. Do not use or fill the system with water until the adhesive has fully cured.

⚠️ Important: Do not apply excessive amounts of adhesive. Excess adhesive can damage the trays, and such damage is not covered by the manufacturer's warranty.

💡 Urban Botaniks tip: When building large EBB & Flow tables, use the original Staal & Plast adhesive. Thanks to the same HIPS material used for the trays, it creates an exceptionally strong, durable bond that withstands daily use and constant contact with water and nutrient solutions.
