Back-rolling is suggested when spraying, working the finish smoothly and evenly to avoid lapping. Always apply a bit of product to a test area and allow to dry completely before coating an entire project to test for color and appearance.

The product should not be applied in the extreme heat of the day. Unfortunately, our deck faces south and we did the job in mid-summer. I discovered we had to work only in early morning, the product dried too quickly to prevent lap marks in the hot sun. Two coats are recommended in order to fill the large, 1/4-in. cracks. And, in a couple of areas we had to apply a third coat. Because the material goes on fairly thick you must brush between the deck boards to cover the sides of the joints.

Coverage may vary, but in most cases it will be 100 square feet per gallon for application of 1 to 2 coats. When filling deep cracks or locking down splinters on old, extremely damaged wood surfaces, additional coats may be required. The product comes with a limited lifetime warranty.

For the last coat Duckback Anti-Skid additive is added.

After the main deck was coated, we cut trim pieces to go around the awning posts and the pool edge. These pieces were precoated, then fastened in place. The pool railings were then reinstalled. We had discovered a lot of rot on the deck boards under the railings, so we raised the railings slightly with wood blocks.

The additive provides a slip-resistant, but comfortable surface.

Trim boards are first routed to create a rounded edge, then cut to 45 degree angles to fit around awing posts. The Bosch cordless miter saw makes the on-site work easy.

Pool railing and benches are stained using Superdeck Transparent stain. Note the benches were stained prior to deck coating. The railings were removed, stained and then reinstalled.
