How to seal siding from water.

Butt the siding next to each other so you can cover more than one piece of siding at a time with the sealer.

Lp recommends applying primer the foundation of the house before painting the siding to prevent moisture from wicking into the siding. The temperature should be be no colder.

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. After the paint dries apply caulk and then paint the rest of the siding. Stack your new siding on top of some scrap wood on a level place in the yard. Lay the siding out on sawhorses or on a horizontal surface to make applying the sealer easier.

Set up your saw horses about 6 feet apart in a shady area. Using a standard sized roller instead of a short roller speeds the process of applying the sealer. Check to be sure weep holes are open along bottom of window openings.
