Attaching Plastic Lattice To Concrete: Best Practices

how to attach plastic lattice to concrete

Plastic lattice is a common building material used for a variety of applications, including decks, patios, porches, and fences. When it comes to attaching plastic lattice to concrete, there are several methods that can be employed. One popular method is to use screws, typically stainless steel pan head screws for outdoor applications. It is recommended to pre-drill the plastic with holes slightly larger than the screw size to accommodate the expansion of the plastic lattice. Another method is to use glue or adhesive to attach the lattice to the concrete surface. Additionally, when working with lattice panels, it is advisable to set them in a wood frame for stability and ease of attachment.

Use glue to attach plastic lattice to cement block walls

While it is possible to attach plastic lattice to a cement block wall using glue, it is not recommended as the lattice may not hold for long and could take some of the wall with it when removed. If you do decide to use glue, a product called Liquid Nails LN903 is recommended, but only if it has a metal plug. This can be purchased at Home Depot or any hardware store. Elmer's glue is another option that some people have found to be more effective than Liquid Nails.

If you opt for Liquid Nails, you will need to use a concrete drill bit to drill holes into the mortar joints with a masonry bit and insert plastic anchors for added support.

An alternative method is to use a glue gun, which heats up a solid glue stick and forces the melted portion through a nozzle onto the surface you want to glue. This method is most often used for hobbies and crafts, but some people have found it effective for sticking things to cinder blocks.

Another option for attaching items to cinder block walls is to use self-adhesive hangers. These are foam-backed devices that stick to the wall by peeling off the back protective coating to reveal the adhesive. However, these are typically meant for lightweight items only.

Pre-drill holes in the plastic lattice

When attaching plastic lattice to concrete, it is important to pre-drill holes in the plastic lattice before screwing it in place. This is because plastic lattice expands a lot, so it needs to be able to float. By pre-drilling holes that are slightly larger than the screw size, you can accommodate this movement.

To pre-drill holes in the plastic lattice, start by measuring the size of your screws. It is recommended to use a stainless steel pan head type screw for outdoor installations. Select a drill bit that is slightly larger than the screw size to allow for the expansion and movement of the plastic lattice.

Mark the locations for the holes on the plastic lattice, spacing them evenly along the edges or any other areas where you plan to secure the lattice to the concrete. Make sure you have a stable work surface and clamp the lattice in place if needed to prevent it from shifting during drilling.

Use a power drill or a handheld drill with a drill bit that is appropriate for drilling through plastic. Place the drill bit at the marked location and drill slowly and carefully to create a smooth, even hole. Drill to a depth that is slightly deeper than the length of your screws to provide adequate clearance for the screw head.

By pre-drilling the holes in this manner, you allow for the natural expansion and contraction of the plastic lattice, reducing the risk of the material warping or cracking over time. This technique ensures that your lattice remains securely attached to the concrete while accommodating the inherent movement of the material.

Use stainless steel pan head screws for outside installation

When installing plastic lattice outdoors, it is recommended to use stainless steel pan head screws. Before screwing, it is important to pre-drill the plastic with holes slightly larger than the screw size. This is because plastic lattice expands, so the holes need to be oversized to accommodate this movement.

Stainless steel is the best choice for outdoor installation due to its corrosion resistance. The pan head screw type also provides a larger head, which is beneficial when using a smaller shaft. This allows for a slightly larger hole to be drilled, again accommodating the expansion of the plastic lattice.

When attaching the lattice to concrete, it is important to ensure that the concrete surface is clean and dry. You may also want to consider using a concrete anchor or sleeve to secure the screw in place. This will provide a stronger hold and distribute the weight of the lattice more evenly.

It is recommended to use a washer when installing the screws, as this will help to distribute the pressure and prevent the screw from pulling through the plastic lattice. Make sure to use a drill bit that is specifically designed for concrete or masonry drilling, and always wear appropriate safety gear, including eye protection and gloves.

By following these steps and using stainless steel pan head screws, you can securely attach plastic lattice to concrete for an outdoor installation that is both durable and stable.

Build a wood frame for the lattice panels for stability

Building a wood frame for your lattice panels can be a time-consuming process, especially if you opt for joinery techniques. However, there are ways to simplify the process and still achieve a good result.

Firstly, decide on the pattern of your lattice. You can choose between horizontal/vertical grid lattice or diagonal lattice. The square lattice pattern, where the lattice runs parallel to the edges of the board, is a nice option for a classic look.

Next, gather your materials. The lattice panels can be made with stock 2x8 panels, which are readily available in stores. For the frame, you can use 1x6 boards, and you will also need glue, screws, and cleats. If you're using a cap molding, ensure your screws go through the "meat" of it to avoid interference later. Use deck screws that blend in with the natural colour of the wood.

When constructing the frame, consider using a design that makes use of the sizes of material that are readily available to save time and money. Assemble the frame first and then attach the lattice panels to it. This will save you time and still yield good results. You can attach the lattice with 1-inch panhead screws driven through washers. Drill clearance holes that are slightly larger than the screw shanks to allow for the expansion and contraction of the lattice due to temperature changes.

If you're using vinyl or composite lattice, use a fine-toothed blade to prevent chipping or cracking. Before attaching the lattice, paint or stain it to protect all sides of the wood. You can skip this step if you're using composite or vinyl lattice, but be sure to clean the panels first.

Finally, hang the framed lattice panels using either 3- or 4-inch T- or strap hinges. The number of hinges depends on the length of your panels. For panels shorter than 8 feet, two hinges are sufficient, while longer panels require three hinges to distribute the weight evenly and prevent sagging.

Attach screening to the back of the lattice panels

Attaching screening to the back of lattice panels can be done in several ways. One option is to use glue or adhesive. For example, you could use a two-part epoxy or Loc-Tite PowerGrab, a general-purpose construction adhesive. However, you may need to be creative in keeping the screen tight while the glue sets. Alternatively, you could use a separate frame behind the lattice, with strips of wood lath or 1x2, one behind the lattice and one over the top of the screen to trim it.

Another method is to use screws. If you are installing the lattice outside, you should use stainless steel pan-head screws. It is recommended to pre-drill the plastic with holes slightly larger than the screw size to accommodate the movement of the plastic as it expands. You can also use strips of lattice, cut into two-cell-wide strips, and screw them on as a backer behind the screen.

If you are creating a privacy screen, you may want to consider painting or staining the panels before hanging them. You can then cut the panels to fit the bays and set them against the nailers. Hold the lattice in place and install 1x stops with finish nails. Remember to only drive fasteners into the posts and rails, not the lattice itself. For a snappier look, use 3/4-inch quarter-round for the stops instead of square stock. For a smaller reveal, use 5/4 stock for a 3/8-inch reveal on a 4x4 with 3/4-inch-thick lattice. Miter-cut the stop corners and use construction adhesive before nailing them.

When creating framed lattice panels, you will essentially be sandwiching the lattice fence panel between your frame. Layout your frame, place your lattice on top, and then add the top part of the frame. Use stainless steel screws to attach the frame to the lattice, staggering them to prevent warping. Screw from the inside out to ensure the visible side of the lattice is free of screws.
