The sealant can be coated/plastered, excellent adhesion to most common paints and brushes
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.
- Highly elastic
- Broad adhesive range on a range of standard construction surfaces
- Building material class B2 according to DIN 4102
- Silicone-free
- Resistant to ageing, weathering and UV
- Odourless
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.
- Not suitable for use in building construction joints in accordance with DIN 18540
- 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.
- The setting speed is dependent on the application temperature, the weather and the surface moisture. The setting speed is greatly delayed in cold, damp weather.
- Discolouration may occur in wood containing tannic acid
- For vertical joints, please observe the run-off behaviour of the sealant
- May cause corrosion on metals such as steel, copper and zinc-plated surfaces
- Standing water should be prevented in the acrylic joint as this can lead to erosion
- Acrylic is very unstable in terms of water absorption and release. Since the diffusion behaviour also changes as a result of the differences in water adsorption in the material, neither the water vapour diffusion resistance (μ) nor the diffusion-equivalent air layer thickness (SD) can be measured on this material in accordance with DIN EN 12572. The value of 5,000 is the average value obtained through testing.
- Not to be used in conjunction with pre-compressed sealing tapes
- Not suitable for bonding or filling cavities
- Due to the large number of varnish and glazing formulations, always carry out your own tests on the area first, especially on alkyd resin paints and powder-coated aluminium
- For sealing indoor and outdoor expansion joints
- For window sealing in the system with Window and façade-tight. The painter's acrylic is used for indoor sealing and the window and façade sealant for the outdoor sealing.
- Adhesion surfaces must be clean, dry and firm
- A primer, e.g. with Silicone primer, improves the adhesion for absorbent or porous surfaces
- Please observe the "General Notes on Application for Sealants" overview sheet. For more information, please refer to the technical data sheet.
