Hardened polyurethane foam should be protected against UV exposure by painting over or sealing with e.g. silicone, polyurethane, acrylic or hybrid polymer, or by covering. Primer should be applied to porous and absorbent substrates. Joint foam B1 can be used in the PURlogic Xpress, art. no. 0891 152 4 foam guns. Other guns are not compatible!
The usage instructions are recommendations based on the tests we have conducted and based on our experience; carry out your own tests before each application. Due to the large number of applications and storage and processing conditions, we do not assume any liability for a specific application result. Insofar as our free customer service provides technical information or acts as an advisory service, no responsibility is assumed by this service except where the advice or information given falls within the scope of our specified, contractually agreed service or the advisor was acting deliberately.

Joint foam B1 is a flame-resistant, ready-to-use, single-component, self-expanding polyurethane foam delivering excellent filling properties. Ideally suited for applications with B1 requirements such as filling joints, holes and cavities with foam, i.e. between insulating panels, roof finishings, roller shutter boxes, as well as in the construction of equipment and metalworking. For insulating window sills, window frames as well as in refrigerated lorries and walk-in refrigeration construction.
Protect the surfaces adjacent to the working area against contamination before starting work. Ensure that elements that can become deformed such as window sills and door frames are sufficiently secure. Shake can vigorously 20 times before use. Screw the can all the way into the gun support - do not screw too far or tilt. Foam continues to expand after application. Immediately remove splashes of foam with PURlogic Clean, art. no. 0892 160. Thoroughly clean the gun and valve after use. Always leave the open can screwed onto the gun. For more information, please refer to the technical data sheet.
