What to know before buying

Listing details to confirm

The listing gives a 24-hour full cure, but its application text separately says to protect the sealant from water for at least 3 hours and describes a surface skin forming in 5–20 minutes, with curing around 4–5 mm per day depending on conditions and bead thickness. It also conflicts on colour, describing grey elsewhere as brown, black and clear, and on application details, referring variously to a nozzle, direct squeeze use and clear silicone. Confirm the exact product colour and follow the packaging instructions for preparation, application and water exposure.

Customer feedback describes good results on small jobs, quick drying and colour matching, but also reports messy application and some tubes splitting at the bottom. Views on size and value are mixed. That feedback is relevant to this 50 ml squeeze tube: its quantity can suit a small repair, but it may disappoint on larger work or if the tube proves difficult to handle.

Positive themes

Customers report that it works well for small jobs, dries fast and matches colours well.

Negative themes

Customers report messy application and tube bottoms splitting.

Mixed feedback

Feedback is divided on whether the small size and price are worthwhile.
