METHOD OF APPLICATION

PREPARATION

The application temperature is between +5 °C and +30 °C. For a more effective application and expansion, the packaging must be at a temperature of +20 °C. It should be kept at room temperature for at least 12 hours before application.
Shake can vigorously for approximately 1 minute before use, with valve turned low.
Screw the foam can onto the applicator gun, the foam output can be adjusted with the trigger and controlled with the adjustment screw on the back of the gun OR in case of manual application place the cannula on the can, the foam extrusion can be controlled by varying the pressure on the adapter.

APPLICATION

You should always keep the can head to bottom during application.
It is recommended to moisten the area before applying the foam, humidity speeds up the cure time, better adhesion and guarantees a better result.
Apply to foam by pressing the trigger, not material to be cast in horizontal and vertical strips 2-3 cm long. The application surface must be 5 cm inside the edges. Wait 1 minute after applying the foam and you can join the surfaces. If the material is heavy, it must be clamped at the end of the cure. The application can be corrected in 5 minutes.
When the application is interrupted for a period between 5 and 10 minutes, it is necessary to clean the gun, using CHEMIFOAM POLYURETHANE FOAM CLEANING SPRAY.

CLEANING

The fresh foam can be cleaned with the CHEMIFOAM POLYURETHANE FOAM CLEANING SPRAY, just like the gun used in the application.
Cured foam can be cleaned mechanically with a knife or spatula.

PAINT

Cured foam will discolor if exposed to ultraviolet light.
Paint or coat cured foam for best results in outdoor applications.

RESTRICTIONS OF USE

Does not adhere to PE, PP, PTFE, PMMA, neoprene, and silicone.
Not UV-resistant, painting is recommended to prevent fading.
Due to the wide variety of possible substrates, a prior compatibility test is recommended.
For joints deeper than 5 cm, fill with multiple layers.
