How to fix cracked window ledge.

Use a stiff wire brush to remove all the loose paint and dirt before rubbing down the existing paint with medium grade sandpaper. Fill any chipped or dinged areas with auto body filler putty. Once it is ready you can apply it to the surfaces that require stabilization and repair. Thoroughly clean the break flushing out any potential debris with an eyedropper before applying tape to the back of the crack.

Around all the edges including between the underneath trim and the window sill. Apply the putty to fill the damaged areas smoothing it off even with the sill s surface. Remove any dust with a soft brush. 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.

I prefer using a glue brush to help the epoxy work down into cracks and crevices. Fix any small or medium cracks in your concrete window sill with caulk. 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.

Mix 10 parts of putty to one part activator with a flexible metal putty knife. Then we used a hammer and banged popped the sill upwards being careful to avoid any further damage. Spread and flatten the caulk with a small putty knife. In a disposable container mix up your batch of liquidwood remember the 1 to 1 proportions and let it setup for about 15 minutes.

Clean the glass with dish soap. Mix only what you can use in five minutes or less. Fit the narrow tip of a bottle of silicone latex caulk into each crack and overfill it by about inch. As this may prevent the filler from making a good seal.

Using a syringe or brush apply the adhesive to the crack and allow it to dry completely before you remove the tape. This will keep the adhesive from leaking out the opposite side of the window.
