Q: What is the best way to go
about sealing our windows? The drywall is slightly cracked around
the windowpane. Is there anything we should do to prep this area
before caulking?A: If this is a standard drywall material around the window, I would open the crack approximately twice its size (if a hair line crack), then mix up some 20 minute drywall compound (or use pre-mixed) and apply it into the crack with my finger, using slight pressure. Prior to the mixture hard setting, use a clean damp cloth and wipe down the wall to get rid of any lines or marks from the over fill and allow the existing texture of the wall to bleed through.
The other alternative, if this occurs repeatedly, would be to apply a paintable caulk that is also water washable directly into the crack, again with the finger. Before it sets (usually within 30 minutes), wipe down with a clean damp cloth, again to smooth and to allow the existing texture to bleed through.
Widen small holes and cracks in drywall with a sharp tool. Push the paper covering in so that a ridge doesn't appear underneath the patching. Fill the holes with a spackling compound. Some cracks may require a second application. After the compound has dried, sand with fine-grit paper and prime.
