Installing New Window Trim On The Exterior Of A House.

What happens here

With all the new trim installed, the final step before painting is to caulk all joints, seams, and nail heads. Load a caulk gun with exterior-grade caulk and apply a bead along all edges where the trim meets the window and the siding. Also, fill any visible nail holes. Smooth the caulk with a finger or a caulk tool for a clean, weather-tight seal. This prepares the trim for a smooth paint finish and protects against moisture intrusion.

Goal: Seal all gaps and nail holes for a finished and weather-resistant trim.

What they say

Hide

you take it down and recut it. Now, I got this the window trim all installed and we're out here painting and I'm going to get this thing caulked right now. The joints got little gaps on the joints and caulked nail heads prior to painting that. So, this is the last process of installing this new window trim.
