When you build your outside space with composite decking. What a lovely material for a composite deck! It improves the appearance of your outside space and boosts the value of your home. Composite wood decking, on the other hand, lacks scalloped edges and requires finishing elements to look excellent. What should we do with the composite decking’s scalloped ends?

Composite wood decking with scalloped ends can be installed in a variety of ways. However, many strategies have advantages and disadvantages that distinguish them from one another. To choose the best strategy, we must first determine what is truly going on.

A picture frame’s edge

A deck with a picture frame border has one or more layers of boards surrounding the deck’s perimeter. The deck used as a border is usually parallel to the deck used in the middle. A frame is one of the most typical techniques to finish the ends of composite decking planks.

A picture frame border can be used for more than just concealing the end of an outdoor deck. You may, for example, improve the appearance of your outdoor deck. Whether you choose a frame with one, two, or three boards, it adds a polished, classy aspect to your composite wood deck. Furthermore, it can provide designers with more alternatives for how their designs appear. You can achieve a subtle design by utilizing boards of the same hue, or a dramatic look by using boards of various colors.

The most expensive aspect of a picture frame border is its pricing. An extra joist and blocking must be installed to the deck’s edge. This allows for extra decking to run perpendicular to the deck, allowing the ends to be buried.

Mitered cuts can make picture frame borders difficult to work with. If the mitered joints are not properly assembled. The mitered joints will then open up when the temperature changes and the board expands and shrinks, destroying the appearance of the outdoor composite deck.

Composite fascia board with raised edges

Lintels are also known as “edge joist covers” and “deck lintels.” It is typically used to cover the cutouts at the extremities of the deck frame and the board’s edge joists. Lintels are not difficult to install. During installation, the deck is placed on the deck and trimmed to fit against the edge joists. Simply place the composite fascia board flush with the top of the deck.

Lintels have a clear disadvantage. Place the trim board flush with the end joists, then cover it with the fascia board. Water is likely to become trapped between the fascia and the joists. If water sits on the deck, it will rust.

Even though a joist membrane reduces this risk, it is still a flaw in the design.

Paint the composite deck’s ends

The issue with composite wood decking ends is that they do not match the color of the decking. The composite decking is wrapped in the color of your choosing. The ends, on the other hand, are whatever color you have in your plastic bags and sawdust. Which can vary from board to board. The solution is to paint all of the ends the same color as the decking, as well as the polymer cap. Getting the composite decking ends to match the rest of the deck.

Painting traditional wood decks is a better approach to maintain them. However, painting does not work as well on composite decks. Because the colors will not match, painting the end of the deck may make it seem awful.
