CERESIT  TS67 WINDOW PRO is a high quality polyurethane foam that delivers excellent results in various weather conditions up to –10°C. Product was specially designed for durable external insulation of windows and doors. High movement capacity of the cured foam reliably compensates the movements of the joint caused by temperature changes and movements of construction materials. Elastic foam practically does not have shrinkage and does not crack. High thermal and sound insulation contributes to the optimal temperature and perfect soundproof in room. It is easily usable and specially made for application with an application gun. The foam is self-expanding having very minimal post expansion and curing pressure, contributing further to convenience and accurate dosage during application. At minus temperatures the expansion of the foam is lower. Has excellent adhesion on wood, concrete, stone, metal etc. Yield of the cured foam largely depends on working conditions - temperature, air humidity, available space for expanding, etc. Product does not contain CFC-propellants.

Step by step

Substrate preparation

 

  • Ensure substrates are stable, clean and free of substances likely to impair adhesion.
  • Moisturize mineral, porous substrates (brickwork, concrete, limestone) with water spray for enhanced adhesion.
  • Mask off adjacent areas with foil.
  • The application surfaces must be clean and free from dust. They can be moist, but not iced.

Can preparation

 

  • Application temperature (environment) of this product is +5°C to +30°C.
  • Recomended can temperature is +5 … +30 °C.
  • Store can preferably for at least 12 hours in room temperature.
  • Remove the plastic cap from the can and screw the can tightly onto the can.
  • Shake the can vigorously before use (15 - 20 times).

Application

 

  • When working with the can always keep the can upside down (valve down).
  • The outflow rate of the foam is controlled by pressing the gun trigger.
  • Dispense the foam sparingly to avoid excess overflows. Repeat shaking regularly during application.
  • It is not recommendable to remove the can before it is totally empty. When replacing the can shake the new can vigorously. Unscrew the empty can and replace it immediately to ensure that there is no air left in the gun.
  • If you do not want to replace the can, remove the foam from the gun using PU foam cleaner (e.g CERESIT CLEANER TS100).
  • Hardened foam can only be removed mechanically.

Recommendations

 

Limitations to joint maximal width exist in regard of ambient temperature and humidity levels. In dry conditions (during winter time, in rooms with central heating etc.), in order to get best foam structure and foam properties it is recommendable to fill gaps and joints in several layers by the application of smaller foam strings (up to 3 -4 cm thickness) and slightly moisturizing between every layer.

Please use the applicator tested and approved by producer of the can for best working experience.
