A Coating for Worn Exterior Siding

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. Read more

Diamond Certified Expert Contributor, Greg Severs: Sometimes underneath the paint film you have non-breathing membrane, oil-based coatings, and you can get moisture underneath or you could get trapped gases.

And what happens is on the south and the southwestern exposed elevations, the film heats up, and it causes this to turn into a gas, and it gets trapped underneath and causes a bubble. Read more
