CASTRO VALLEY — When preparing for an exterior painting project, it’s important to inspect the condition of your siding. Particularly on the southern and western exposed elevations, standard plywood siding commonly sustains splits and cracks (known as “face-checking”), which is caused by expansion and contraction over time. Since plywood siding is composed of several layers glued together, if these splits and cracks go deeper than the outermost layer, they’ll pose an increased risk of moisture intrusion. Merely painting over them won’t resolve the issue—the splits and cracks will return soon after, and along with them, the risk of dry rot from moisture intrusion.
Fortunately, there’s a product that can prolong the life of worn siding boards: elastomeric polymer waterproof coating. Applied prior to painting, this coating fills in cracks and splits and seals the siding from moisture intrusion. It’s also flexible, which means it won’t fail when the plywood expands and contracts. By prolonging the life of your siding boards, an elastomeric polymer waterproof coating will secure the integrity of your paint job and prevent dry rot and similar problems.
