Product information and data sheets

The right joint filling compound for domestic stoves

A tiled stove is truly a feature that can turn a house into a home. The sealants used on these masonry heaters have to overcome a number of challenges. Due to the heat that is generated inside, they must be particularly resistant to high temperatures. One product that has been specially developed for these conditions is our 420 Kachelofen. The plasto-elastic, acrylic-based joint sealant can withstand temperatures of up to 180°C and is compatible with natural stone. Thanks to its odourless and low-emitting properties, it is a safe bet for indoor use. Plus, the sealant comes ready-to-use, making it much easier to apply.
