How long does it take to cure?

Plan on 18 to 24 hours of ventilation after applying. Thin coats and good airflow help it set evenly.

Will it really dry clear?

Yes, the cured film is transparent, which is why it suits visible repairs. Thick beads can look slightly cloudy until fully cured.

What surfaces does it work on?

It bonds to many common materials, including tile, glass, metal, plastic and wood. Test a hidden spot first on delicate or painted surfaces.

Can it be used underwater or on wet surfaces?

No. The surface must be dry and free of water stains before application. It resists water after curing, not during.

Is it a substitute for structural adhesive?

No. It is a flexible sealant and repair glue for light household use, not for load-bearing or safety-critical joints.

How much area does 300g cover?

Coverage depends on thickness. Applied in thin coats, one tube handles several small repairs; large areas will need more than one.

Our take on the Transparent Waterproof Glue

A 300g tube of clear polyurethane, silicone rubber and acrylic adhesive meant for sealing and bonding around the home. It cures clear so repairs stay invisible, and it is flexible and water resistant once set. The 18 to 24 hour cure is slow compared with fast-setting silicone sealants, and it is not a structural adhesive. Best for small household leaks, tile and trim repairs, and outdoor touch-ups where appearance matters.
