You may think that plastic signs are virtually indestructible, but think again! Taking proper care of these signs is crucial to ensure their longevity and effectiveness.

From cleaning and washing to protecting them from sunlight and weather conditions, there are dos and don’ts that every sign owner should be aware of.

In this discussion, we will explore the best practices for maintaining and caring for plastic signs, giving you the knowledge you need to keep your signs looking their best and conveying your message with clarity.

So, let’s dive into the dos and don’ts of plastic sign maintenance and care!

Cleaning and Washing

To keep your plastic sign looking its best, regularly clean and wash it using mild soap and water. This simple maintenance routine will ensure that your sign remains vibrant and appealing, creating a sense of belonging and connection for your audience.

Start by preparing a cleaning solution with mild soap and warm water. Avoid using harsh chemicals or abrasive cleaners, as they can damage the surface of the sign. Gently scrub the sign with a soft cloth or sponge, focusing on any dirt or stains. Rinse thoroughly with clean water to remove any soap residue.

If your plastic board sign has stubborn stains or grime, you can use a non-abrasive cleaner specifically designed for plastic surfaces. Apply the cleaner according to the manufacturer’s instructions and use a soft cloth or sponge to scrub away the stains. Rinse thoroughly afterward to remove any residue.

In addition to regular cleaning, it’s important to inspect your plastic sign for any signs of damage or wear. If you notice any cracks, scratches, or fading, it’s best to address them promptly to maintain the sign’s appearance and effectiveness.

Protection From Sunlight and Weather

Protect your Corrugated Plastic Signs from the damaging effects of sunlight and weather by taking proactive measures. By protecting your sign, you can ensure its longevity and maintain its vibrant appearance.

The sun’s UV rays can cause the colors on your sign to fade over time, making it less effective in conveying your message. To prevent this, consider applying a UV protective coating to your sign. This will create a barrier between the sign and the sun, reducing the harmful effects of UV radiation.

Weather conditions such as rain, snow, and extreme temperatures can also impact the durability of your plastic sign. Moisture can seep into the sign’s material, causing it to warp or crack. To avoid this, make sure your sign is properly sealed and waterproofed. Use weather-resistant adhesives and ensure all seams and edges are sealed tightly.

In addition, consider placing your sign in a location that offers some natural protection from the elements. For example, positioning it under an overhang or in a shaded area can help minimize exposure to direct sunlight and reduce the risk of damage.

Regularly inspect your sign for any signs of wear or damage. If you notice any cracks, scratches, or fading, take immediate action to address the issue.

Storage and Handling

Ensure the longevity and effectiveness of your plastic sign by properly storing and handling it. By following these guidelines, you can keep your sign in pristine condition and maximize its impact:

  • Clean and dry before storage: Before storing your plastic sign, make sure it’s clean and dry. Remove any dirt or debris using a mild detergent and a soft cloth. This will prevent any build-up that could damage the sign over time.
  • Avoid excessive heat: Plastic signs are susceptible to warping and distortion when exposed to high temperatures. Store your sign in a cool, dry place away from direct sunlight or heat sources to prevent any damage.
  • Handle with care: When moving or handling your plastic sign, be gentle to avoid scratching or cracking the surface. Use both hands and avoid applying excessive pressure or force.
  • Store in a protective sleeve or cover: To provide additional protection, consider storing your plastic sign in a protective sleeve or cover. This will prevent any accidental scratches or other damage that could occur during storage or transportation.
  • Store vertically or flat: When storing your plastic sign, ensure it’s kept upright or flat. Storing it on its side or at an angle may cause it to bend or warp over time.

Avoiding Harsh Chemicals and Abrasives

When caring for your plastic sign, it’s important to avoid using harsh chemicals or abrasives. These substances can cause damage to the sign’s surface, leading to discoloration, scratches, or even permanent marks. Instead, opt for gentle cleaning solutions and soft materials that will effectively clean your sign without causing any harm.

To clean your plastic sign, start by using a mild soap or detergent mixed with warm water. Apply the solution to a soft cloth or sponge and gently wipe the surface of the sign in a circular motion. Avoid using excessive force or scrubbing vigorously, as this can cause scratches or other damage.

When it comes to choosing cleaning materials, opt for non-abrasive options such as microfiber cloths or soft-bristled brushes. These materials are gentle enough to clean the sign without causing any harm. Avoid using abrasive materials like steel wool or rough sponges, as they can scratch the surface of the sign.

It is also important to avoid using harsh chemicals such as bleach, ammonia, or solvents. These chemicals can cause the sign’s colors to fade or even dissolve the plastic material. Stick to mild cleaning solutions and avoid anything that’s too strong or corrosive.

Regular Inspections and Maintenance

To keep your Corrugated Plastic Sign Boards in optimal condition, regularly inspecting and maintaining it’s essential. By taking the time to perform routine inspections and maintenance tasks, you can ensure that your sign remains attractive and functional for years to come. Here are five important steps to include in your regular sign maintenance routine:

  • Clean the sign surface: Use a mild detergent and a soft cloth to gently clean the sign surface. Avoid using harsh chemicals or abrasive materials, as they can damage the plastic and cause it to deteriorate over time.
  • Check for any cracks or damage: Inspect the sign carefully for any cracks, chips, or other signs of damage. If you notice any issues, it’s important to address them promptly to prevent further deterioration and potential safety hazards.
  • Inspect the mounting hardware: Check the mounting hardware to ensure it’s securely fastened and in good condition. Loose or damaged hardware can compromise the stability of the sign and increase the risk of it falling or becoming damaged.
  • Monitor the sign for fading or discoloration: Over time, exposure to sunlight and other environmental factors can cause plastic signs to fade or become discolored. Regularly monitor your sign for any changes in color and take appropriate steps to protect it from further damage.
  • Remove any debris or obstructions: Keep the area around your sign clear of debris, such as leaves, dirt, or other obstructions. These can’t only detract from the appearance of your sign but also potentially cause damage if left unattended.

Conclusion

So there you have it! By following these simple dos and don’ts, you’ll be well on your way to giving your printed plastic board signs the love and care they deserve.

Remember, the irony here is that while plastic signs are often seen as low-maintenance, they still require a little TLC to stay looking their best.

But hey, who said taking care of signs couldn’t be a fun and rewarding experience?

Happy sign-keeping!
