⚡ At a Glance
- • Adhesion Strength: Strong initial tack and long-term elastic hold on timber, glass, metals, ceramics and plastics
- • Best for: Caravan and motorhome owners and repair professionals needing hygienic, weatherproof seals
- • Not ideal for: Applications requiring silicone or solvent-based formulations or non-white colour matching
Moisture-curing, silicone and solvent-free sealant formulated for caravan and motorhome repairs. Contains fungicidal ingredients and meets ISEGA hygiene standards for use where food is prepared.
Durable, flexible sealing - with moisture-curing, silicone and solvent-free chemistry
Moisture-curing chemistry allows the sealant to cure into an elastic polymer without silicone or solvents, helping maintain flexibility over time. The formulation resists cracking under movement common in caravans and motorhomes.
Elastic seals remain watertight through vibration and thermal movement, reducing the need for repeat repairs. Users get a reliable joint that keeps its shape rather than becoming brittle.
Hygienic, mould-resistant finish - thanks to high fungicidal ingredients and ISEGA certification
Contains fungicidal agents designed to reduce mould growth in areas with ventilation and air conditioning, and holds ISEGA certification for use where foodstuffs are prepared. The chemistry supports use in hygiene-sensitive interiors.
Seals in kitchens and food-preparation areas stay cleaner for longer, lowering the risk of mould and odours. Ideal for cramped or damp caravan interiors where airflow is limited.
Stable white finish outdoors - with UV and weather-resistant formulation
Formulated to resist the effects of UV exposure and weathering, improving colour stability for white finishes exposed to sunlight. The UV tolerance reduces yellowing and discolouration over time.
Exterior joints retain a neater, whiter appearance after prolonged sun exposure, saving time on touch-ups. Good choice for visible seams on motorhome exteriors.
