How can I repair cracks in my bathtub?

You can repair it with Poxipol Transparente.

Before using it, make sure the surfaces to be joined are clean, dry, and free of grease or rust. Sanding very smooth or shiny surfaces is recommended.

It is very easy to use. Follow these steps:

1) Dispense equal parts of each component. Make sure to apply a bead of at least 2 cm of each component.

2) Mix for at least approximately one minute, until obtaining a uniform colour.

3) Apply the mixture to one of the surfaces to be joined and hold the parts together for 10 minutes.

Keep in mind that the product hardens in just 10 minutes, but reaches its maximum strength after 24 hours.
