Emerald exterior is the thickest most durable exterior paint we have encountered in our 17 years of painting exteriors in the Northwest.
Emerald Exterior paint fills cracks or gaps where moisture would otherwise penetrate
Perfect example: This board is about 24 feet off the ground. These split cracks are invisible to the homeowner but moisture will find them and saturate the board until it developed dry rot and becomes a very costly repair (that is if you can find a quality contractor willing to come out for a small job)
