Bond and Seal 290ml Cartridge

Primary Pro Bond & Seal is a specialist sealant designed to work with Primary Pro insulation, helping create strong, weather-resistant seals on external heat pump pipework.

Bond & Seal is used to seal insulation joints and pipe entry points. When applied correctly, it helps prevent moisture ingress, heat loss and weather exposure, ensuring the insulation system performs as intended.

The sealant can also be used to secure Primary Pro insulation or pre-insulated flexible pipes to the heat pump, helping maintain a durable seal even where vibration from the heat pump may occur.

Bond & Seal remains flexible even once cured, allowing it to expand and contract with temperature changes and outdoor conditions.
