CERESIT TS22 is a universal polyurethane foam featuring innovative combined straw and gun adapter, which allows the user to choose the preferred application method to use, depending on the need. Product can be applied up to -10°C temperature. Application comfort is ensured both with a gun and the delivered applicator. Straw-applicator offers opportunity to use the product already familiar to the user and also for applications, where straw-applicator is more beneficial and effective. In comparison with traditional strawfoams Ceresit TS22 ensures improved foam structure and higher yield output due to special narrower straw-applicator. Gun-applicator offers more convenience and ergonomic comfort as well as more accurate dosage. The foam is self-expanding and during the curing process expands about 2 to 2.5 times until cured, due to which some free space for expanding must be considered. 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 -10°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 either screw the plastic pipe tightly onto the can or screw the can direct and tightly onto the can. 
  • Shake the can vigorously before use (15 - 20 times).

Application with the straw

  • Shake the can vigorously before use (15 - 20 times).
  • Attach the fixing end of the foaming straw adapter tightly into the slot provided on the gun-adapter by turning the straw 90° and pushing the connecting tube-detail firmly onto the valve, avoiding undesirable opening of the valve.
  • A slight click will indicate that the straw tube-connection is properly attached.
  • Dosage of the product can be adjusted by pressing the trigger.
  • Since the foam is expanding 2 to 2.5 times until cured, some free space for expanding should be left. If there are longer pauses than 5 minutes during working, the nozzle and valve must be cleaned.
  • For cleaning, the straw can be clicked onto the PU Foam cleaner valve.
  • Important is to clean thoroughly the connecting parts – valve and straw tube-detail to avoid undesirable valve opening during repeated application.

Application with the gun

  • Shake the can vigorously before use (15 - 20 times).
  • Screw the can tightly onto the gun. When working with the gun always keep the can upside 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. 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.
