What happens here

Move to the exterior of the window to apply caulk. For exterior gaps, which may be larger, adjust the cut on the caulk tube tip to create a wider bead if necessary. Apply the Tower Sealants AU-1 caulk carefully into the exterior gaps. Pay close attention to environmental conditions, particularly heat, as high temperatures can cause the caulk to skim over and dry quickly, making it difficult to tool. Apply caulk in manageable sections to ensure it can be smoothed before it dries.

Goal: Seal exterior window frames against weather and drafts

Tools and materials

  • Caulk Gun — Dispensing caulk for exterior application

What they say

now so i got my gap on the outsides is bigger than in the inside so i'm going to cut my tube of my caulking a little bit bigger still at a 45 degree angle none of these gaps are big enough that i need to use the backer rod on the other window i had with gap that was big enough i used bachelor rod [Music] it's really hot outside so you can't go very far before your caulking will start to skim over on the top and not be very toolable so you want to be aware of how hot it is how fast your caulking is drying [Music]
