Can be coated/plastered over

Excellent adhesion of commercially available paints/plasters onto the sealant

Wide range of applications

Suitable for joints indoors subject to less stretching.


Resistant to ageing, weathering and UV


Not suitable for use in building construction joints in accordance with DIN 18540. Due to the wide variety of paint and lacquer formulas available, we recommend that you always carry out preliminary testing in order to rule out any interactions. Caution: Sealant joints that have been fully painted over tend to crack when movement occurs in the joint, as the applied paint is generally less elastic than the sealant. The setting speed is dependent on the application temperature, the weather and the surface moisture. The speed is greatly delayed in cold, damp weather. Discolouration may occur in wood containing tannic acid.

Not for use in contact with pre-compressed sealing tapes.

Acrylic sealant is not suitable for adhesive bonding or filling cavities. Due to the large number of varnish and glazing formulations available, always carry out your own tests on the area first, especially on alkyd resin paints and powder-coated aluminium.
