Our products featuring the EMICODE label are low emission/environmentally compatible. The EMICODE classification system awards labels to construction products that comply with the very stringent health and environmental requirements of recognised institutes.
- It should be painted over within the first three days after sufficient skin formation. Subsequent application of paint may cause adhesion problems.
- Due to the large number of varnish and glazing formulations, preliminary testing is required in order to rule out any interactions
- Take care with sealant joints that have been fully painted over. These tend to develop cracks when movement occurs in the joint, as the applied paint is generally less elastic than the sealant and then causes cracks to form in the paint.
- Alkyd resin paints can cause drying problems
- Risk of yellowing in contact with white alkyd resin paints and substances containing plasticiser, such as butyl, bitumen and VKP tapes, cannot be excluded
- As a general rule, in line with DIN 52452 Part 4, sealants should not be painted over
- In the case of particularly sensitive natural stone, such as Jura and Carrara marble, preliminary testing is required
- Remove excess smoothing agent from surfaces
- Not suitable for use in floor joints for traffic routes
