wrapping bollards done by installers in TorontoA few days ago, our team completed a bollard wrapping project at Toronto Pearson International Airport in Mississauga, Ontario, and we wanted to share our insights with you, our fellow installer.

Materials

Wrapping bollards with vinyl graphics is an effective way to enhance safety and, in some cases, provide branding or add decorative elements to a space. For this project, we utilized high-quality materials to wrap the bollards:

  • High-quality vinyl films (we used cast vinyl) to ensure UV resistance and weatherproofing for outdoor installations.
  • Protective laminate layer, crucial in high-traffic areas such as airport hangars and garages, to prevent scratches, fading, and other damage.
  • Surface primer to improve adhesion, especially on rough surfaces that required wrapping.
  • Surface cleaner to remove dirt, dust, and grease from the bollards prior to installation.

Preparation

Proper preparation is key to ensuring that the vinyl adheres securely to the bollard, preventing bubbles, peeling, or damage over time:

  • Our team begins by thoroughly cleaning the bollard to remove any dirt, dust, grime, or oil that might interfere with vinyl adhesion. For this task, we use a mixture of water and isopropyl alcohol (70-90% concentration).
  • Next, we use a microfiber cloth to scrub the surface, ensuring all contaminants are fully removed. Special attention is given to grease spots or tough stains, as they can cause poor adhesion over time.
  • After cleaning, we allow the surface to dry completely before moving on to the next steps, sometimes using a heat gun to speed up the drying process. It’s crucial to ensure no moisture remains, as it can lead to issues during installation.
  • We thoroughly inspect the bollard’s surface for any rust, cracks, or imperfections that could disrupt the vinyl application. For rust removal, we use a wire brush, and for more severe cases, a rust remover is necessary. Afterward, we clean the surface again to eliminate any remaining residue.
  • For bollards with deep scratches, we fill them with a suitable filler, allowing it to dry before sanding the area smooth to create a level surface for the vinyl.
  • At the end of the preparation, we conduct a final inspection to ensure the bollard is smooth and free from defects.
  • Next comes measuring and cutting. We start by measuring the bollard’s circumference and height using a flexible measuring tape, which guides the cutting of the vinyl for accurate application.
  • We add a small overlap (1-2 inches) to the circumference to ensure the vinyl fully wraps around the bollard without gaps, leaving a slight excess (about half an inch) at the top and bottom for trimming after installation.
  • Using a precision knife, we cut the vinyl film with clean, straight edges. For complex shapes, we pre-cut smaller sections of vinyl to help the film conform to those areas during installation.

Installation Process for Bollard Wraps

  • Our installers begin by peeling back a small portion of the backing at the top or bottom of the bollard, using alignment marks to position the vinyl precisely.
  • Slowly remove the backing as you work your way down, applying the vinyl section by section to prevent large portions of the vinyl from sticking prematurely.
  • Using a felt-edged squeegee, installers press the vinyl onto the bollard. Work from the center outward, using firm, even pressure to smooth the vinyl and push out air bubbles in small sections.
  • Tack down edges – we pay extra attention to the edges of the vinyl, ensuring they adhere well, especially around any curves, by applying additional pressure and heat.
  • Bollards at this project were cylindrical with curved tops, so gentle stretching was necessary to make the vinyl conform. While applying heat with the heat gun, we lightly stretch the vinyl to wrap around curves. General advice: be cautious not to overstretch, as this can lead to warping or weakening of the material.
  • For bollards with a rounded top, we cut the vinyl into small, evenly spaced slits (relief cuts) to allow it to fold neatly around the curve. We applied heat and stretched each section individually to eliminate wrinkles.
  • In the case of seam overlap, we ensure that the vinyl overlaps slightly at the seam where the edges meet. A 1/4 to 1/2-inch overlap is typically enough to prevent peeling while keeping the seam inconspicuous. For straight seams, we use a straightedge and precision knife to trim the overlap for a clean, straight seam. Keeping the seam straight not only improves the appearance but also reduces the likelihood of dirt and moisture collecting at the joint.
  • When most of the vinyl is applied, we trim any excess material around the top or bottom of the bollard using a sharp precision knife to ensure clean, straight cuts for a professional finish. After that, we go over the entire surface again with the heat gun, focusing on the edges and seams. This final heat treatment activates the adhesive, promoting a stronger bond and helping the vinyl fully conform to the surface.
  • For extra durability, based on the high-traffic and outdoor conditions at Pearson Airport, we apply an edge sealer to protect the vinyl’s edges from peeling or lifting over time.
  • Lastly, we inspect surfaces for bubbles. For small bubbles, we use a pin to puncture them and smooth out the air with a squeegee. Finally, our installers ensure that all edges and seams are properly adhered and that there are no visible wrinkles or defects, so the wrap will be durable and long-lasting.

Challenges to Avoid

One common issue is air bubbles forming under the vinyl. Using a proper felt-edged squeegee and working slowly in small sections can help minimize this risk. Begin smoothing from the center and push outward toward the edges to prevent bubbles from becoming trapped. In cases where bubbles remain, carefully puncture them with a pin and apply heat while pressing out the air with a squeegee. Heat softens the vinyl, making it easier to smooth out stubborn bubbles, but it must be applied evenly to avoid distorting the material.

If the seams are misaligned or poorly cut, they can become more noticeable and lead to premature peeling. Seam overlap should be measured accurately, and the alignment should be straight for a clean look. Use a straightedge and a precision knife to create straight, professional seams. Double-check measurements before cutting to avoid alignment issues. Seams that overlap too little may lift over time, while excessive overlap can appear bulky.

Even small amounts of dirt, dust, or oil on the bollard can prevent proper adhesion of the vinyl. Any contamination can create bumps or gaps that affect the overall appearance and reduce the longevity of the wrap. Be meticulous during the cleaning process by using a 50/50 isopropyl alcohol and water solution to thoroughly clean the surface. Make sure to dry the bollard completely before starting the vinyl application.

Excessive stretching, especially around curved surfaces, can lead to premature wear, distortion of printed graphics, or vinyl tearing. Apply heat gradually and stretch the vinyl just enough to mold it into place, avoiding overstretching. Stretching should be minimal and controlled, particularly around seams and edges where vinyl is most vulnerable to warping.

Uneven or excessive heat can cause the vinyl to warp, weaken, or lose its adhesive properties. Use a heat gun at a moderate temperature, applying heat consistently and evenly across the surface. Keep the gun moving to prevent burning or bubbling of the vinyl, especially around curves and edges.

Vinyl edges are prone to lifting if not properly adhered, particularly in high-traffic or outdoor environments. Ensure that all edges are pressed down firmly and use an edge sealer for added protection. Edge sealing is particularly crucial for bollards in high-impact areas to prevent peeling.

Durability Considerations

Outdoor bollards are exposed to various weather conditions, from rain and snow to high heat and UV exposure. Vinyl rated for outdoor use is essential, particularly in regions with extreme climates, such as Toronto’s winters. Vinyl wraps designed for cold weather conditions are easier to install and maintain adhesion during temperature fluctuations. Choose weather-resistant vinyl with UV protection and cold-weather adhesive. This helps prevent fading, cracking, or peeling due to environmental factors. Laminating the wrap can further enhance its weather resistance.

Bollards in high-traffic areas, such as parking lots or airports, are likely to experience more wear and tear from frequent contact or accidental bumps. Thicker vinyl with protective laminates will enhance durability. Use a thicker vinyl (e.g., 3M IJ180mC or Avery Dennison MPI 1105) along with a strong over-laminate to withstand scratches, scuffs, and minor impacts. A matte or gloss laminate can also protect the print from abrasion.

In areas where bollards are likely to be hit by vehicles, the wrap must withstand impacts without tearing or peeling. Standard vinyl may not hold up well in such situations, especially without proper reinforcement so consider using impact-resistant or reinforced films, such as reflective or protective overlays, to extend the wrap’s lifespan. Vinyl with built-in protection against scuffing, abrasion, and minor impacts can significantly enhance durability.

Prolonged exposure to sunlight can cause the vinyl to fade or degrade over time, especially for brightly colored wraps. Select vinyl with built-in UV protection to minimize fading and discoloration. Laminating with a UV-resistant laminate will provide additional protection against the sun’s harmful rays.

Bollards exposed to de-icing salts or industrial chemicals need wraps that can resist these corrosive elements. Salt, in particular, can break down vinyl and adhesives over time, causing wraps to peel or degrade. Choose vinyl wraps and laminates that are specifically designed to resist salt and chemicals. Regular cleaning of the bollard surface also helps to prolong the life of the wrap in these environments.
