Window and Door Frame Sealant

Preparation

1. Joint surfaces must be sound, clean and free from contaminants such as dust, oil, grease and any loose material. 

2. If desired, place masking tape along the joint edges before application.  

Application

3. Unscrew the nozzle, and using a sharp knife, carefully cut off the dome of the window and door frame sealant, taking care not to damage the thread. Screw the nozzle on to the cartridge. 

4. Cut off the tapered end of the nozzle at a 45° angle, to a width matching the gap to be sealed. 

5. Fit the cartridge into the cartridge gun by pressing the release plate and pulling out the plunger. Insert cartridge and repeatedly squeeze the trigger until the sealant appears. 

6. Place the nozzle at the start of the gap and gently squeeze the trigger. Push forward slowly, ensuring that contact is made by the sealant with both sides of the gap. At the end of the run, release the trigger and press the plunger release plate of the gun. 

7. Smooth the sealant with a wet, round ended tool (do not use a wetted finger), remove any excess with a cloth moistened with white spirit and then remove the masking tape (if used) from either side of the bead. 

8. After use, ensure to wipe away any excess sealant from the nozzle. Replace the cap.

How to remove

• Uncured sealant: Excess uncured sealant should be removed carefully using a soft scraper. The remainder can be removed using a cloth moistened with white spirit. Repeat using another clean cloth moistened with white spirit. 
• Cured sealant: There is no adequate solvent; carefully cut away excess with a very sharp knife. Do not use solvent to remove product from skin – use soap and water.
