Soudal Firecement HT° - High Temperature Cement Sealant

Substrate Suitability:

Soudal Firecement HT° is suitable for application on brick, concrete, and metals. These rigid substrates offer a solid foundation for the fire cement sealant to adhere to effectively.

Surface Preparation:

Before applying Soudal Firecement HT°, it is essential to ensure that the surfaces are clean, dry, and free of dust and grease. Any loose debris or contaminants should be removed thoroughly.

In the case of porous surfaces, slightly moistening them can improve adhesion. It is always recommended to conduct a preliminary adhesion test on the specific substrate to ensure compatibility and optimal performance.

Application Method:

1. Cut the Nozzle: Cut the nozzle of the cartridge at a 45-degree angle to control the size of the bead. The size of the nozzle opening should match the width of the joint or gap you are sealing.
   
   

2. Load the Cartridge: Load the cartridge into the caulking gun according to the manufacturer's instructions. Make sure it is securely in place.
   
   

3. Apply Consistent Pressure: Apply consistent pressure on the caulking gun trigger to dispense the sealant. Start at one end of the joint or gap and steadily move along its length.
   
   

4. Fill the Gap: Apply the sealant directly into the joint or gap, ensuring it is completely filled. Make sure the sealant makes contact with both sides of the joint for optimal adhesion.
   
   

5. Smooth the Surface: For best results, spray the surface with a soapy solution before the sealant begins to skin. This solution enables easy smoothing and ensures a smooth, professional finish. You can use a caulking tool or a wet finger to smooth the caulk and remove any excess.
   
   

6. Curing Time: Allow the sealant to dry and cure according to the manufacturer's instructions. The curing time may vary depending on environmental conditions, but ensure the caulk is fully cured before painting or finishing.

Finishing:

Once the sealant is applied, it can be smoothly finished using the Soudaglatt Smoothing Tool or a similar tool of your choice. Simply run the tool smoothly along the sealant line to create an even finish.

If a smoothing tool is not available, a wetted finger can be used to achieve a similar effect. Perform the finishing process before the sealant begins to skin, ensuring a neat and tidy appearance.

Coverage of any sealant product varies depending on Joint Width and Joint Depth.

Joint Dimensions:

• Minimum Width for Joints: 5 mm
  
  

• Maximum Width for Joints: 15 mm

Cleaning:

Clean any uncured sealant immediately after use with water. Wipe off any excess sealant to avoid it drying on surfaces. Please note that once the sealant cures, it becomes difficult to remove. Therefore, it is essential to clean the product residue promptly.

Remarks:

• A slight heating up of the installation during 12 hours after application of Firecement HT° will prevent the forming of bubbles and improve the sealant structure.
  
  

• Do not apply in situations where constant water immersion is possible
