How to fix cracked window ledge.

Apply the putty to fill the damaged areas smoothing it off even with the sill s surface. Wash the glass around the crack with a drop or two of dishwashing soap on a damp cloth. Then we used a hammer and banged popped the sill upwards being careful to avoid any further damage. 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.

Fit the narrow tip of a bottle of silicone latex caulk into each crack and overfill it by about inch. Remove any dust with a soft brush. Around all the edges including between the underneath trim and the window sill. I prefer using a glue brush to help the epoxy work down into cracks and crevices.

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. Use a stiff wire brush to remove all the loose paint and dirt before rubbing down the existing paint with medium grade sandpaper. Once it is ready you can apply it to the surfaces that require stabilization and repair. At this stage the biggest thing to watch for is any rot that may be around the frame.

We pulled out the rest of the nails that were left behind. Mix only what you can use in five minutes or less. Spread and flatten the caulk with a small putty knife. You ll want to remove any dust oil or fingerprints and then wipe.

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. Mix 10 parts of putty to one part activator with a flexible metal putty knife. Thoroughly clean the break flushing out any potential debris with an eyedropper before applying tape to the back of the crack.

Fill any chipped or dinged areas with auto body filler putty. This will keep the adhesive from leaking out the opposite side of the window.
