How to fix cracked window ledge.

Apply the putty to fill the damaged areas smoothing it off even with the sill s surface. Thoroughly clean the break flushing out any potential debris with an eyedropper before applying tape to the back of the crack. Fit the narrow tip of a bottle of silicone latex caulk into each crack and overfill it by about inch. I prefer using a glue brush to help the epoxy work down into cracks and crevices.

Mix 10 parts of putty to one part activator with a flexible metal putty knife. This will keep the adhesive from leaking out the opposite side of the window. 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. As this may prevent the filler from making a good seal.

At this stage the biggest thing to watch for is any rot that may be around the frame. Using a syringe or brush apply the adhesive to the crack and allow it to dry completely before you remove the tape. Fill any chipped or dinged areas with auto body filler putty. Mix only what you can use in five minutes or less.

Scrape away any mess with the edge of the knife. Spread and flatten the caulk with a small putty knife. Fix any small or medium cracks in your concrete window sill with caulk. Then we used a hammer and banged popped the sill upwards being careful to avoid any further damage.

Use a stiff wire brush to remove all the loose paint and dirt before rubbing down the existing paint with medium grade sandpaper. We pulled out the rest of the nails that were left behind.

Wash the glass around the crack with a drop or two of dishwashing soap on a damp cloth. In a disposable container mix up your batch of liquidwood remember the 1 to 1 proportions and let it setup for about 15 minutes.
