How to Use Silicone Caulking to Glaze Windows
- 1). Slide the point of a utility knife blade around the connecting point between the plate glass -- whole or broken -- and the frame surrounding the windowpane. Ensure all existing glazing putty or caulk is scored.
- 2). Pry the wood stops -- securing the glass to the window frame -- by sliding the flat end of a regular screwdriver between the wood stop and the window frame and prying upward on the screwdriver handle. Set each wood stop in a safe location. Pull the glass gently from the frame.
- 3). Push the blade of a putty knife along the face of the plate glass to remove all remaining glazing putty from the edges of the pane.
- 4). Secure a tube of silicone caulk in a drop-in caulk gun. Apply a 3/16-inch wide bead a caulk to the face of the wood frame that will sit against the glass. Set one setting block 5 to 6 inches from each corner of the window frame. Press each block firmly into the bead of caulk.
- 5). Push the cleaned glass against the silicone caulk. Press one wood stop against the glass. Secure the stop with two finishing nails installed gently with a hammer. Install the remaining wood stops to install the window. Wet one finger. Run the finger over the caulk to smooth it to the window.
- 6). Allow the silicone caulk to cure for 24 hours. Scrape the glass face with a putty knife to clear the window of excess caulk
