How to Break Plexiglass with Hammer

Last Updated on January 10, 2023

It is important to understand that Plexiglass is not a fragile item like glass and requires specific methods to break it safely and successfully. Taking the wrong approach can lead to dangerous splinters and shards of plastic being flung around, or worse yet, serious injuries due to improper use of a hammer.

Plexiglass is durable and resistant to most types of impacts, making it difficult to break without specialized tools. With a hammer and some force, you can break plexiglass into smaller pieces. But it isn’t as simple as just hitting it with a hammer. The best way to break a plexiglass with a hammer is to use a chisel-pointed hammer.

If you’re looking for techniques for how to break plexiglass with a hammer, then read on. We’ll explain the right way to use a hammer and chisel to break plexiglass safely and effectively.

Step-By-Step Guide on How to Break Plexiglass with Hammer

Step-By-Step Guide on How to Break Plexiglass with Hammer

Breaking Plexiglass with a hammer is an effective and efficient way to cut through the strong and durable material. The trick is to hit the plexiglass with enough force in one area for it to break, without shattering it completely. Here’s a step-by-step guide that will help you break plexiglass with a hammer:

The very first step is to make sure you have all the necessary tools before attempting to break the plexiglass. You will need to gather the following materials:

  • Chisel-pointed hammer
  • Rubber mallet hammer
  • Glass cutter
  • Safety glasses
  • Thick gloves
  • Protective clothing or suit
  • Plywood board or other protective surfaces

Once you have all of the necessary tools, it’s time to start breaking the plexiglass. Let’s get started:

Step 1: Prepare the Work Area

Before beginning the process of hammering plexiglass, prepare the work area for safety. It is important to cover your work area properly with sheets of newspaper or plastic bags, as this will help contain any flying shards of glass during the breaking process.

Step 2: Place the Plexiglass on a Firm Surface

The process of breaking plexiglass requires a firm and stable surface to ensure that force is correctly applied and that the breakage is achieved as desired. It’s important to make sure the surface is flat and free from any obstructions.

Place the plexiglass on top of a solid wood cutting board or other durable, high-density material to ensure it does not move when being struck. If possible, secure it with clamps to avoid any risk of movement during the breaking process.

Step 3: Mark the BreakPoint with a Glass Cutter

To accurately mark your break point with precision before using a hammer, you should use a glass cutter or another sharp marking tool to score along it. This helps create an exact breaking point for when you begin to apply force with your hammer.

The scoring is recommended to be around 0.4 to 0.5 cm deep so that you can clearly see where you will want to apply pressure when striking downwards later. Be sure not to press too hard when scoring, as this could cause misalignment or cracking of the material around where you intend to break it off.

Step 4: Putting Force on the Plexiglass with Hammer 

Once your line has been scored accurately and firmly, it is time to put force onto the plexiglass using an appropriate-sized rubber mallet or hammer (depending on preference). While doing this step, make sure that you’re wearing protective gloves as well as safety goggles since there may be flying pieces after impact.

Then strike directly over your marked line with one or two strong blows depending on how thick your piece of plexiglass is and if it requires extra force due to its thickness/strength.

Each hit should be a few millimeters apart so that it creates pressure and stresses only at one point instead of multiple ones, which will cause unwanted cracks around your breaking point rather than exactly where you wanted them to happen.

Step 5: Finishing Touches After Successful Breakage Occurs

Once successful breakage has occurred, there are some finishing touches that can be done to make sure everything looks smooth and clean afterward. In most cases, simply running your hand along both edges of each side should provide adequate smoothing out of any rough edges caused by excess pressure during striking.

Still, additional sanding can also be used so that all surfaces are flush with one another when reassembled if required. This will prevent any potential injury from occurring if anyone happens to touch them accidentally later on down the road when handling/moving around pieces of broken plexiglass glassware in general.

Also, if there were bits left behind which did not get completely broken off during the initial attempt, then lightly tap them once more until they completely disconnect. Don’t forget to collect any fallen glass shards and dispose of them properly. You can sweep them up or even use a vacuum cleaner with a special bag to collect them safely.

By following the above steps, you can safely break plexiglass using a hammer and ensure that your home depot project turns out just as expected. It is easy to work with this material with the right tools and safety protocol.

Important Tips When Breaking Plexiglass With a Hammer

Important Tips When Breaking Plexiglass With a Hammer

Using a hammer to break plexiglass can be a difficult task if the proper precautions are not taken. To ensure that the job is done correctly and safely, there are several important tips to keep in mind prior to breaking plexiglass.

1. Wear Heavy-Duty Gloves: Since broken tempered glass can be sharp and dangerous, having an extra layer of protection between your hands, and the broken glass will help ensure your safety during this process.

2. Wear Safety Glasses: Eye protection is always important when working with any type of glass, especially when hammering or striking it with force. Protect your eyes from potential harm during this process by wearing a safety glass at all times.

3. Dispose Of Broken Pieces Appropriately: After breaking plexiglass, it is essential to dispose of any broken pieces appropriately after completing the task. To ensure that no sharp pieces remain around that could potentially hurt someone. 

4. Inspect Remaining Edges Carefully: Inspecting the remaining edges of the sheet for potential cracks or breaks prior to starting work on it is also an important step in this process. These edges should be carefully examined for any irregularities before attempting to break the acrylic sheet. 

5. Properly Store, Handle & Transport Remaining Sheets: It is critical that any remaining plexiglass sheets are properly stored, handled, and transported once they have been broken down into smaller pieces as this will help reduce any chance of further damage or breakage occurring while they are being moved around or stored away in storage areas or bins.

6. Turn Off Necessary Power Sources Before Cleaning Up: Make sure all necessary power sources, such as electricity or gas have been turned off before attempting to clean up any broken pieces, as these can present serious safety hazards if left unattended for too long. 

By following these important tips, you can ensure that your project is completed safely and without problems.

What Is the Breaking Force of Plexiglass?

What Is the Breaking Force of Plexiglass

The breaking force of plexiglass is incredibly strong, requiring an impressive 8,000 to 10,000 psi to shatter it. Plexiglass is a type of plastic that is exceptionally strong and shatterproof. It is much more resistant to impact than most types of glass, making it a great choice for safety applications.

Plexiglass breaking strength is often referred to as its “toughness” or “impact strength” due to its exceptional resistance to impact damage. The extra strength provided by the plastic material also helps protect against cracking and shattering compared to traditional glass.

Plexiglass can withstand up to ten times more impact without failure than regular glass, making it one of the strongest materials available for various applications. Also, it does not shatter like glass, reducing the risk of accidental injury from sharp edges or shards.

Does Plexiglass Melt or Burn?

Plexiglass, also known as acrylic glass, is a strong and durable material that can withstand high temperatures. Although, it does soften at temperatures above 200°F (93°C) and will melt at 320°F (160°C). Plexiglass is not easily flammable and will not burn easily under normal circumstances.

Then again, if it is exposed to an open flame or extreme heat, it may catch fire and burn. To avoid any damage to the plexiglass, it is important to keep the temperature below 200°F (93°C). Plexiglass can also get brittle when exposed to cold temperatures for too long, so use caution in cold climates.
