Repair Cracked Plexiglass Windshield

Although plexiglass windshields are resistant, they still can crack due to accidents, harsh weather, or general wear and tear. These cracks may start small, but if they are not fixed timely, they may grow larger and weaken the windshield. 

Start by cleaning the area around the crack using a soft cloth and mild soap. Once it’s clean, apply clear glue along the crack. Gently press the edges together, then let the glue dry. After it dries, sand any extra glue for a smooth finish. If the cracks are major and can’t be fixed easily, seek professional windshield repair services.

4 Simple Ways To Repair Cracked Plexiglass Windshields

Fortunately, there are easy ways to repair cracked plexiglass windshields, and if the case is not too severe, you can even try fixing it yourself. 

1. First, Properly Clean the Area

Before starting, clean the cracked plexiglass with a soft cloth and mild soap. Wipe the surface in circles to remove dirt. Rinse the cloth and wipe again to remove any soap.

2. You Can Try Acrylic Polish

Another effective way to repair a cracked plexiglass windshield is to use acrylic polish. However, this method is only effective for small cracks. It helps fill the minor scratches and smooth the surface. All you have to do is rub the polish in circles, then clean it with a microfiber cloth. 

3. Buffing Compound is Another Option

For bigger cracks, try a buffing compound. To use this method, a small amount of buffing compound is applied to the cracked plexiglass. Spread it evenly using a brush or a towel. Then, use a dual-action polisher with a foam compounding pad. Move the polisher straight across the cracked area, ensuring overlap. This technique helps make the surface even and reduces the crack’s visibility.

4. Solvent Cement is a Great Option

Another great option to repair cracked plexiglass windshields is solvent cement. This is how to use it for the repair process:

  • Gently apply the cement along the crack, being careful not to use too much. 
  • After applying the cement, press the cracked parts together and hold them firmly until the glue dries. 
  • You can also use clamps or strong tape to hold the parts in place but don’t tighten them too much. 
  • Once the glue is dry, you may smooth out the edges.
  • It is recommended to start with a rough sandpaper and then move to a finer one for a smooth finish. 
  • After sanding, polish the plexiglass with plastic polish and a soft cloth to make it look shiny and clear again.

How to Repair Cracks in Clear Plastic?

You can fix cracks in clear plastic using plastic glue. Apply the glue along the crack, press the edges together, and let it dry. This works well for small cracks. However, for larger or more complex damage, it’s advisable to consult professionals experienced in auto glass repair or plastic repair to ensure a durable fix. Sanding and polishing the area afterward can help restore the clarity of the plastic.

How to Make Plexiglass Clear Again?

To make plexiglass clear again, use acrylic polish paste and rub it gently in circles. Be careful not to overdo it. For deeper scratches, you may need to sand the area lightly with fine-grit sandpaper before applying the polish for a smoother finish.

Can Cracked Acrylic Be Repaired?

Yes, drill small holes at the crack’s ends to stop it from spreading, then fill the crack with silicone sealant. Let it dry to restore the acrylic. For best results, ensure the area is clean and free of debris before applying the sealant, as this will improve adhesion and durability.
