How To Repair A Hole In An External Wall?

This video demonstrates how to fill small and large holes in your home’s exterior, including those going from the inside to the outside. Foam gap fillers are useful but not the best way to seal exterior surfaces, as they break down faster when exposed to sunlight and water. An exterior-grade caulk is recommended for this purpose.

To fix a hole in drywall, you will need repair patches for drywall, joint compound, drywall knife, and sanding block. Start by removing loose debris from the hole and cutting it. If you have an exterior wall that you plan to paint, the best way to fill exterior wall holes is to use a masonry filler. These are designed for external use, providing a strong, durable surface that can be painted.

For interior drywall, apply patching compound and a spackle or putty knife to smooth out the hole. Fill in the internal side with filler flush with the hole and do the same for the outside. Use a cement repair product like Earl’s 1kg Concremate Expanding Cement to fill the hole, and use a scraper to push it into the hole.

For a temporary seal, sheet plastic stapled on the studs can create dead air space and provide insulation. A good outdoors silicon caulk, either clear or paint-able white, is usually needed. Sanding everything can improve the end result, but it’s essential to follow proper procedures to prevent bugs from entering and maintain the appearance of your home.
