How to fix cracked window ledge.

Fix any small or medium cracks in your concrete window sill with caulk. Wash the glass around the crack with a drop or two of dishwashing soap on a damp cloth. Using a syringe or brush apply the adhesive to the crack and allow it to dry completely before you remove the tape. I prefer using a glue brush to help the epoxy work down into cracks and crevices.

Thoroughly clean the break flushing out any potential debris with an eyedropper before applying tape to the back of the crack. We pulled out the rest of the nails that were left behind. At this stage the biggest thing to watch for is any rot that may be around the frame. Remove any dust with a soft brush.

Spread and flatten the caulk with a small putty knife. Rub off flaking paint or loose concrete along the crack with the wire brush and make sure to clean out any moss that may be growing inside. Fill any chipped or dinged areas with auto body filler putty. As this may prevent the filler from making a good seal.

Once it is ready you can apply it to the surfaces that require stabilization and repair. In a disposable container mix up your batch of liquidwood remember the 1 to 1 proportions and let it setup for about 15 minutes. Apply the putty to fill the damaged areas smoothing it off even with the sill s surface. Around all the edges including between the underneath trim and the window sill.

Fit the narrow tip of a bottle of silicone latex caulk into each crack and overfill it by about inch. Mix only what you can use in five minutes or less. Mix 10 parts of putty to one part activator with a flexible metal putty knife. You ll want to remove any dust oil or fingerprints and then wipe.

Use a stiff wire brush to remove all the loose paint and dirt before rubbing down the existing paint with medium grade sandpaper. Be careful to rub down the edges where any larger flakes of paint came away so that you have a nice smooth gradient for the new paint.
