Easy Guide: Installing Plastic Lattice On Your Deck

how to install plastic lattice on deck

Installing plastic lattice under your deck can improve your home's exterior while offering practical benefits such as storage and pest control. Plastic lattice is made of vinyl, which is durable and water-resistant, reducing maintenance. It is also lightweight, making it easier to handle and install. Plastic lattice is commonly available in 2-foot and 4-foot heights, and 8-foot lengths. Before installing, ensure that there are no animals living underneath your deck. You can do this by allowing as much light in as possible and running a water hose next to the deck. To install, you will need to drill holes and use wood screws to attach the lattice to the deck's rim joist or beam.

Plastic lattice installation tools and requirements

Plastic lattice is a great, low-cost way to refresh your deck, providing privacy and a clean, unified look. It is also easy to install, with no special tools required. However, it is important to plan carefully and gather the necessary tools and materials to ensure a successful installation.

First, you will need to select the right type of plastic lattice for your needs. Plastic lattice is typically made of vinyl, which is durable, water-resistant, and low-maintenance. It is commonly available in 8-foot lengths and 2 to 4-foot heights, with diamond and square styles being the most popular. If you prefer a different colour to the standard white, you can special order colours like black, green, grey, or brown.

Next, you will need to measure the area where you plan to install the lattice and transfer those measurements to the lattice panels. If you need to cut the lattice, use a blade suitable for cutting plastic. Pre-drill holes every 24 inches around the perimeter of the lattice, making them slightly larger than the screws you will use to fasten the lattice to the deck. You may also want to drill pilot holes when screwing into two pieces of framework, especially if it is close to the end or side of the material.

To attach the lattice to your deck, you can screw it directly into the vertical posts and rim joist or beam. Use screws that are long enough to securely attach the lattice but not so long that they protrude through the other side. You may also want to use straps or T-hinges to attach framed lattice panels. To stabilise the lattice and reduce any flimsy movement, you can install vertical 2x2s at 4-foot intervals.

Finally, consider adding trim pieces, decorative caps, or finials to enhance the appearance of your lattice and provide a more finished look. You can also paint the lattice to match your deck, but this will require touch-ups if it gets scratched during installation. Alternatively, you can leave the plastic lattice as it is, as the colour is baked-in, and benefit from its inherent durability.

Removing old lattice

To remove old lattice from your deck, you will need a few tools. A flat pry bar will be essential for this task, so make sure you have one at hand. If you encounter any issues with removing the lattice, a reciprocating saw can be used to cut the lattice into pieces, making it easier to pry off. A small carpenter's cat's paw will also be useful for pulling out nails, and if the lattice is stapled, a flat-head screwdriver can be used to gently pry off the staples.

Before beginning the removal process, inspect the lattice to identify how it is attached to the deck. Look for nails, screws, or staples, and take note of any damage to the lattice or the deck itself. If you notice any animals living under the deck, it is important to encourage them to leave by allowing natural light to enter the space and running a water hose nearby.

Once you have assessed the situation, start by carefully prying off the lattice from the deck using the flat pry bar. Be cautious not to damage the deck's surface, support columns, or fascia boards during this process. Work slowly and methodically, using the other tools as needed to remove nails, screws, or staples. Cut the lattice into smaller sections with the reciprocating saw if it is difficult to remove in one piece.

After removing the lattice, inspect the area for any remaining fasteners or debris. Ensure that all nails, screws, or staples are removed, and use a putty knife or a similar tool to scrape away any residual adhesive or caulk. Sweep or vacuum the area to remove any dirt, leaves, or other debris that may have accumulated.

Finally, examine the deck for any damage that may have been hidden by the lattice. Look for signs of rot, insect infestation, or structural issues. Address any problems you find before installing the new lattice. This may include repairing or replacing damaged wood, reinforcing structural components, or seeking professional advice if you encounter complex issues. Remember to wear protective gear, such as gloves and safety goggles, during the removal process to safeguard against any sharp objects or debris.

Attaching the lattice to the deck

  • Measure the openings between the columns or posts of your deck. Lattice is commonly available in 2-foot and 4-foot heights, and 8-foot lengths, so you may need multiple pieces for taller decks.
  • Cut the lattice to the required size. For vinyl lattice, use a blade suitable for cutting plastics, and for wood lattice, use a fine-toothed blade.
  • If you are joining two pieces of lattice, secure the seam by screwing the panels together where they meet at the center stile. Use 1-inch pan-head screws with washers, and drill two rows of screws for added strength.
  • Pre-drill holes around the perimeter of the lattice, approximately every 24 inches. The holes should be slightly larger than the screws you will use to attach the lattice to the deck.
  • Position the lattice against the installation area and screw it into place. Use wood screws or, if screwing into framework, consider drilling a small pilot hole first. The lattice should be slightly movable to allow for expansion and contraction.
  • If desired, attach trim pieces or moulding to the edges of the lattice for a more finished look. You can also paint or stain the lattice to complement your deck and home's architecture.

It is important to note that plastic lattice may require additional support due to its flimsy nature. You can install vertical 2x2s at 4-foot intervals to stabilize the lattice, with all framing on the inside for a neat appearance.

Stabilising the lattice

Planning and Preparation:

Before you begin, it's important to select a lattice design that complements your deck and meets your personal preferences. Consider factors such as the desired level of privacy and airflow, as tighter spacing offers more privacy, while wider spacing enhances airflow. Additionally, decide whether you will paint or stain the lattice, as this can impact its overall aesthetic and longevity.

Framing Techniques:

To stabilise plastic lattice effectively, you can implement the following framing techniques:

  • Install a horizontal cross-member along the bottom, using a 2 x 4 outdoor wood piece.
  • For raised decks, consider installing vertical supports at 4-foot intervals. This can be achieved using 2 x 2s, placed inside the framework for a neat appearance.
  • Cut the frame parts to the desired length and assemble them face down on a flat surface.
  • Strengthen the frame by installing a 6-inch mending plate and a 3 1/2-inch flat corner brace at each corner joint. Position the hardware pieces about 1/4 inch from the edge of the frame and secure them with 3/4-inch-long flathead screws.

Securing the Lattice:

Once the framing is complete, it's time to secure the lattice panels:

  • Pre-drill holes around the perimeter of the lattice approximately every 24 inches. Ensure the holes are slightly larger in diameter than the screws you will use.
  • Hold the lattice against the installation area and screw it into place using suitable screws and washers. Ensure the lattice can slightly move to allow for expansion and contraction.
  • If you are joining multiple pieces of lattice, create a seam on the centre stile and secure it with two rows of screws.
  • Attach the framed lattice panel to the deck using straps or T-hinges. Screw the hinges to the lattice frames first, then to the deck using a drill with a screwdriver head.

Remember to follow the specific instructions provided by the manufacturer of your chosen lattice product, as well as adhering to any relevant safety guidelines when undertaking this project.

Maintaining the lattice

Regular Cleaning:

It is important to regularly clean your plastic lattice to prevent the buildup of dirt, debris, and grime. Use a mild detergent, warm water, and a soft-bristled brush or cloth to gently clean the lattice. Avoid using abrasive cleaning tools or strong chemicals as they may damage the plastic.

Protect from Weather Conditions:

Weather conditions such as rain, snow, and sunlight can impact the condition of the plastic lattice over time. Consider applying a UV-resistant and waterproof sealant to protect the lattice from fading, cracking, or warping due to exposure to sunlight and moisture.

Stabilize with Additional Supports:

Plastic lattice can be slightly flimsy, so it is recommended to stabilize it with vertical supports at regular intervals. Install vertical 2x2s or similar supports at 4-foot intervals to provide additional stability and reduce any wobbling. This will also create a neater and more robust overall appearance.

Inspect for Damage:

Periodically inspect the lattice for any damage, such as cracks, holes, or loose sections. Repair any damage promptly to prevent it from worsening. You can use plastic-compatible adhesives or, as one source suggests, stainless steel staples to secure any loose sections or make repairs.

Consider Privacy and Aesthetics:

If you wish to enhance privacy or create a cleaner aesthetic, you can attach vinyl sheets to the lattice. Use clear vinyl sheets and attach them with compatible glue, double-sided tape, silicone, or construction adhesive. Ensure that the adhesive is clear and compatible with both plastic and vinyl to avoid any visible seams.

By following these maintenance instructions, you can help ensure that your plastic lattice remains in good condition and retains its functionality and appearance. Regular care and prompt repairs will extend the lifespan of the lattice and maintain the overall appeal of your deck area.
