This Mastic Sealant is designed for caravan, motorhome, and boat owners needing a durable, waterproof seal for overlap joints, awning rails, rooflights, and window surrounds. Its key benefit is providing a reliable, long-lasting barrier against the elements. A potential caveat is its specific application focus, requiring careful surface preparation for optimal adhesion.

It is designed for use on common materials found on caravans, motorhomes, and boats, including aluminum, fiberglass, plastics, and wood.
When applied correctly to prepared surfaces, the seal is designed to be durable and long-lasting, providing a reliable barrier against the elements for an extended period.
This product is typically not designed to be painted over. It is a sealant intended to provide a visible waterproof barrier.
This specific product is a 5-meter length roll with a 32mm width.
While primarily designed for external applications on vehicles, it can be used for interior sealing tasks requiring a durable, waterproof joint where its properties are beneficial.
Store the roll in its original packaging, in a cool, dry place away from direct sunlight and extreme temperatures to maintain its adhesive properties.
Ensure surfaces are thoroughly cleaned, dry, and free from contaminants like dust, oil, or old sealant residue. Apply firm, even pressure during application.
This can occur if the surfaces were not properly prepared or if the tape was stretched too thinly during application. Ensure adequate overlap and even pressure. For existing gaps, consider re-applying sealant after proper surface preparation.
Apply only the necessary amount of tape. Trim excess sealant carefully after application if required, once it has slightly set but is still workable.
Ensure your fingers are dry and try using a small tool like a craft knife to gently lift the edge of the liner before peeling.
Setup: Ensure the surfaces to be sealed are clean, dry, and free from dust, grease, or old sealant. Cut the mastic tape to the required length. Peel back the release liner and apply the tape firmly to one surface. Press down to ensure good contact. For overlap joints, apply to one surface, then position the second surface over the tape and press firmly to create the seal. Ensure even pressure is applied across the width of the tape.
Compatibility: This mastic sealant is generally compatible with common materials found on caravans, motorhomes, and boats, including aluminum, fiberglass, plastics, and wood. Always test on an inconspicuous area if unsure.
Care: Once applied, the sealant requires minimal care. Regularly inspect sealed areas for any signs of dislodgement or damage. Clean the exterior of the sealed area with mild soap and water; avoid abrasive cleaners or solvents that could degrade the sealant.
