Underseal, black

Clean the surfaces to be treated thoroughly in advance and remove rust. The surfaces must be dry and free of wax, dirt and grease and largely free of dust.

Shake well before use! The adhesion is improved if the surface to be treated is roughened first. Can be applied with the UBS Spray Gun (part no. 6219) or the Compressed Air Can Gun (part no. 6220) at an operating pressure of 2 – 4 bar depending on the desired spray pattern. Can be painted over after approx. 60 – 90 min. (depending on film thickness, temperature and humidity). Most of the usual water and solvent-based 2C paints and base coats can be used here. When using a 2C paint, we recommend using a coat of plastic primer first and painting over this coat after it is completely dry, as recommended by most paint manufacturers.

Recommended application temperature: 15 – 25 °C

We recommend applying thin coats. Depending on the desired layer thickness, intermediate drying should be carried out after each layer. If the stoneguard is subsequently painted over, the coats will become increasingly hard. In other words, the treated surface should be treated accordingly with adhesive primer for plastics in the same way a plastic surface would be.

Do not leave containers standing open as a skin will form on the surface of the material.
