Give your deck that updated look with Lowe’s Severe Weather™ composite railings and lattice. If you haven’t already, review the instructions for part one of this series, which will explain how to install the composite posts. In this part, we’re going to show you how to attach the composite railings and lattice.
Use this checklist when you go to the store and purchase your items.
Measure the distance between the posts. Also, account for the brackets when determining rail length. For example, with our railing system, we subtracted ½ inch for the brackets.
Place the bottom rail next to the top rail, line up the holes and mark the length.
Cut the rails to length with a saw.
Attach the crush block to the middle of the bottom rail using PVC glue, following the manufacturer’s instructions. The crush block helps provide support to the middle of the rails.
Once the PVC glue has cured, assemble the railings. Insert the spindles in the holes on the top and bottom rails. Slide the end caps on the rails.
Hold the railing in place between the posts, making sure the end caps are centered, and lightly trace around them. You might need help holding the railing in place.
Set the railing aside and remove the end caps.
Hold the railing assembly between the posts above the flanges, then press downward to lock all the caps.
Replace the railing posts as needed following the previous instructions.
Place the top and bottom rails with attached brackets on the stairs, next to the posts, as shown in the diagram. Make sure the end baluster holes are equal distance to each post. Use a pencil to mark the angle of the rail to the perpendicular post. Typically, it will be about 32 degrees.
Cut the rails and attached brackets with a saw. Be sure the precut baluster holes are lined up on the top and bottom rails.
Assemble the railings as noted in the previous instructions.
Position the assembled rail section on the posts and mark the screw locations.
Drill the bracket holes with a 1/8-inch drill bit.
Attach the brackets to the posts with screws to secure the railing.
Install the post caps. Many simply snap into place.
You can cover bolt holes from old posts by installing fascia boards. For best results, use treated lumber about 2 inches narrower than the rim and end joists, then you can attach lattice to the exposed joist areas.
Install the vinyl lattice.
