Can You Flame Polish an Acrylic Pool?

Acrylic is among the most versatile materials when it comes to building glass pools or aquariums for homes, hotels, and spa centers. There are various methods to achieve a glass-like appearance. So, you may wonder: can you flame polish an acrylic pool? 

Read on for the answer!

Can You Flame Polish an Acrylic Pool?

When it comes to acrylics, flame polishing is possible. It is a method that offers a stunning result.

Due to their susceptibility to scratching, polishing is a must to achieve a glass-like surface on acrylic sheets and have a clear glass pool. Flame polishing ensures stunning and clear visuals for home glass pools, spa centers, an acrylic aquarium, etc.

It’s a technique for polishing acrylic materials’ surfaces and edges using a controlled flame. The flame effectively melts the minuscule defects on the acrylic surface, leaving behind a glass-like smooth sheen.

How to Flame Polish Acrylic Edges 

After cleaning the acrylic piece, any visible defects are sanded away. So, can you flame polish acrylic with a propane torch? Yes, the flame polishing technique requires the use of a propane blow torch. The heat from the propane blow torch is then carefully applied to the edges or surfaces of the acrylic pool.

The heat from the blow torch melts the acrylic, smoothing out any imperfections. When executed correctly, the result of flame polishing is a highly polished, glossy, and smooth surface.


The first step is the preparation phase. While it is not the most complicated process, it requires skill and precision. The preparation phase involves smoothing edges using sandpaper.

When sanding acrylic sheets, it is crucial to always sand in one direction to achieve homogeneity. Sanding also helps to remove scratches and marks from the pool wall surfaces and edges. 


The next step is to scrape the acrylic sheets. Depending on the size of the acrylic sheets, you may use a buffing wheel or simply a knife. Scraping the acrylic edges helps achieve an incredibly smooth surface. Scraping the pool wall surfaces prepares them for the final step.

Finally, the acrylic sheets are ready for the last step: flame polishing. A propane blow torch is often used for flame polishing acrylic sheets, as it puts out a hot pinpoint flame.

To achieve the glass-like finish, you should keep moving the flame over the edges until the results are visible. However, handling the blow torch carefully is vital to prevent overheating from generating bubbles or warping.

If done correctly, flame polishing will cause the edges to melt momentarily, smoothing out any imperfections. After flame polishing, the acrylic sheets will give off the appearance of glass.

Safety Precautions When Using a Propane Blow Torch

You have to exercise caution when carrying out this procedure. When using an open flame of any kind, it is vital to follow safety precautions. When flame polishing acrylic edges, follow these safety procedures:

  • Ensure that you always wear safety goggles to protect your eyes from acrylic shavings and the hot flame. 
  • The area where the flame polishing will occur should be free from any flammable objects
  • Wearing gloves is crucial because the propane blow torch provides a hot flame. The gloves also shield from any sharp acrylic edges. 
  • The area where the flame polishing is done should be well-ventilated to disperse the vapors.
