How to seal siding from water.

Set up your saw horses about 6 feet apart in a shady area. Check to be sure weep holes are open along bottom of window openings. Cover it with a tarp to keep it from sustaining sun or water. Stack your new siding on top of some scrap wood on a level place in the yard.

Since water runs downward unless it s being driven by strong winds the standard method for creating water resistant vinyl cladding is to start at the bottom and work up. Inspect the area above the leak including both indoors and out. After the paint dries apply caulk and then paint the rest of the siding. Butt the siding next to each other so you can cover more than one piece of siding at a time with the sealer.

Lay the siding out on sawhorses or on a horizontal surface to make applying the sealer easier. If you prefer to caulk before painting you should still paint the cut ends first. Use a caulking gun to apply a continuous bead of silicone sealant along the vertical seams between the vinyl j channels and the exterior window casings.
