12 Step-by-step Instructions on How to Finish Composite Deck Stairs

Step 1: Select the Right Materials for Your Project. 

The type of material you use will determine the longevity and durability of your stairs. Composite decking is a popular choice for many homeowners due to its low-maintenance, long-lasting properties.

However, there are other materials that you may want to consider such as natural wood, PVC or aluminum. If you’re unsure of what type of material to use, consult with a professional or research the different options available. But, whatever you decide, make sure the material is strong, durable and designed for outdoor use.

Step 2: Measure Out the Length and Width of Your Staircase

Before you start constructing your stairs, it is important to accurately measure the length and width of your staircase. This will help you determine how much material you will need for the project as well as plan out a more precise design for your stairs.

It is also important to consider any existing structures, such as railings, that you might need to work around. This will help you to come up with a unique design that fits your vision and space.

Step 3: Install the Stringers (the Structure that Supports the Steps)

Installing stringers is an essential step in building composite deck stairs. These provide stability and act as a foundation for your steps. When installing stringers, make sure that you level them correctly and use the correct hardware to keep them in place.

Installing Stringers is an Essential Step

If you are unsure of how to do this, it is best to consult with a professional who can provide guidance and advice. it also important to note that the number of stringers you use will depend on the size and shape of your stairs.

Step 4: Cut the Treads (the Actual Steps)

Once the stringers are in place, it is time to cut your treads or steps for your staircase. This can be done by either using a circular saw or pre-made composite stair risers. Make sure that your measurements are precise and double check them before cutting!

Although this may take some time, it’s important to get the measurements right if you want a professional-looking finish. But don’t stress if you make a mistake – there is always the option to start over and try again.

Step 5: Place Your Composite Decking Boards in Place

When placing boards into place, start from the bottom of the stairs and work up toward the top. Attach each board with deck screws and drill pilot holes beforehand to avoid splitting. Be sure to double check that your boards are level and secure. It is also important to note that a minimum of 25mm should be left between each board.

Step 6: Add Composite Skirting

Composite skirting is a great way to give your stairs a polished, finished look. You can find composite skirting in various colors and designs to match the existing design of your staircase. Place the skirting around the edges where needed and attach it with deck screws.

Handrails serve as an important safety measure

But be sure to measure and cut carefully, so that the skirting fits snugly and looks professional. This will also help ensure that the skirting stays in place and does not move or shift.

Step 7: Install Handrails

Handrails serve as an important safety measure for stairs, so make sure to install them properly! Attach handrails on both sides of the stairway at an appropriate height (typically between 36-42 inches). When installing handrails, be sure to use lag bolts or another type of strong fastener to keep them secure.

Step 8: Add Finishing Touches

Add any additional finishing touches such as lighting, post caps or decorative accents to make your stairs more attractive and customizable. Be sure to take into account the overall design of the space before adding any decorative elements. It is best to keep the design cohesive and make sure everything works together.

Step 9: Clean Up Your Work Area

Once you have finished constructing your composite deck stairs, it is time to clean up the work area. Remove any tools that were used in the process and dispose of any debris properly. You want to make sure that all surfaces are free from dirt in order to prevent slips or falls. But don’t forget to sweep away any sawdust or material particles that may remain!
