Den Braven K2 AKRYL BIAŁY 300 ml is a white acrylic sealant formulated for interior sealing and filling tasks. Supplied in a 300 ml cartridge, this acrylic product bonds to common building substrates such as wood, plaster and masonry and remains paintable after curing. It is intended for finishing around window and door frames, skirting boards, crown mouldings and for repairing narrow cracks and gaps in indoor environments.
Advantages
The sealant cures to a flexible, paintable joint that accommodates minor substrate movement while maintaining adhesion. Its white colour provides a neutral finish that is easy to overpaint with water-based and many solvent-based interior paints. The cartridge format fits standard caulking guns for controlled application, and the acrylic formulation is easy to tool and clean from tools and fresh joints with water.
Suitable for
- Sealing joints around interior window and door frames
- Filling gaps between skirting boards and walls
- Repairing hairline cracks in plaster and masonry
- General finishing and trim work in dry interior spaces
When it may not be suitable
This acrylic sealant is formulated for indoor use and is not intended for continuous exposure to water or for exterior joints that face severe weathering. It is not recommended for use on some plastics, bituminous substrates or metals subject to significant movement without prior compatibility testing. For high-movement expansion joints or waterproofing applications, a silicone or polyurethane product designed for those conditions should be considered.
Key specifications
- Formulation: acrylic-based sealant
- Appearance: white, paintable finish
- Packaging: 300 ml cartridge suitable for standard caulking guns
- Elasticity: provides flexible cured joint for minor movement
- Application: interior use on porous and painted surfaces such as wood, plaster and masonry
How to use
Ensure surfaces are clean, dry and free from dust, grease and loose particles. Cut the cartridge nozzle to the required bead size, insert into a standard caulking gun and apply an even bead into the joint. Tool the sealant within the skinning time to obtain a smooth finish and remove excess with a damp cloth while still fresh. Allow the joint to cure fully before painting; drying time depends on bead size, temperature and humidity.
What to consider before purchase
- Intended location: designed for interior use only
- Substrate compatibility: suitable for porous materials like wood, plaster and masonry; test on non-porous or unknown plastics
- Finish requirements: white and paintable—ensure paint compatibility
- Movement expectations: suitable for minor movement but not for large expansion joints
Usage recommendations
For best results, apply at room temperature on dry surfaces and tool the joint within the sealant’s working time. Prime non-porous or problematic substrates if necessary, and allow adequate curing before painting or exposing the joint to regular cleaning.
