Maintaining and Restoring Acrylic Sheet
Acrylic is a transparent plastic used on a wide scale due to its ability to replace glass. It is usually available as acrylic cut to size that is converted into useful products such as sales displays, lenses, protective screens, roofing, windows, TV screen protectors, and many others.
But what makes products such as clear Perspex sheet cut to size the favourite of manufacturing businesses all over the world? The secret lies in the unique properties of this thermoplastic:
- Excellent optical clarity;
- Light transmission that is superior to the one of glass;
- Rigidity and good impact strength; if it breaks, acrylic forms dull pieces unlike glass which shatters into hundreds of sharp and dangerous little shards;
- Being easy to process and model due to excellent dimensional stability and low mould shrinkage;
- Can be sawed and cut using tools similar to those used for wood;
- Has a greater transparency than that of glass and will not present a greenish tint when moulded into thick sheets.
These properties make acrylic and its derived products, like Perspex sheet cut to size, suitable for a variety of uses and applications, such as:
- Furniture such as cabinets and coffee tables;
- Sporting equipment;
- Aquariums;
- Artistic sculpting;
- Protection screens used in sports;
- Sneeze screens that have become increasingly widely used since the Covid-19 pandemic to reduce the spread of the virus.
How to protect and prevent damage
Products and objects made from acrylic can last for years, even decades if you follow some simple protection rules in order to prevent damage, especially when working with acrylic in the creation of other products:
- When storing products such as acrylic sheet cut to size, it is recommended to protect them with polyethylene film overwrap to keep dirt and moisture away. Sheets must be stored vertically or in special racks leaning at an angle of approximately 10º. Plywood panels should be used to provide full support to the material. When acrylic sheets are stored horizontally, they must not be allowed to sag.
- Perspex sheets cut to size are usually delivered with sheet masking; this protection layer should be left on the product to protect the sheet surface. However, if you need to remove masking for detail work, bending, or thermoforming, store the unmasked sheets in the original shipping cartons and avoid unnecessary handling of unmasked sheet;
- Wear rubber gloves when handling acrylic and manipulate it by its edges;
- Neutralise static electricity which can form especially on new Perspex sheet cut to size; static electricity will attract dust, chips, and other small particles floating in the air and will ultimately contaminate the surface. Use an ionising air gun to temporarily eliminate static charges before any operations such as bending, painting, or thermoforming.
How to maintain and clean
The quality of a product comes out as high or low once you start using it. High-quality Perspex cut to size will require little maintenance, but when you need to clean your acrylic products, it is important that you follow some simple rules to keep the surface intact and increase the lifespan:
- Start cleaning acrylic by dusting; this operation will remove particles that can scratch the acrylic if you start washing the material right away. Use a soft, damp cloth to remove dust and avoid dry or gritty cloths that can create static electric charge and cause scratches.
- Wash acrylic sheets with a solution of mild soap or detergent and lukewarm water. Apply light pressure using a clean, soft cloth.
- If you need to remove oil, grease, or tar, use solutions such as kerosene, hexane, or aliphatic naphtha;
- Never use the following solutions on your acrylic objects: window cleaning sprays, acetone, gasoline, benzene, lacquer thinner, alcohol, benzene, or carbon tetrachloride. These can damage the surface of the acrylic sheet or weaken the sheet by causing small surface cracks.
How to repair or restore damaged/scratched acrylic
If your Perspex or acrylic surfaces are looking a little worn make sure you are paying attention. Follow these 4 simple points to learn how to improve the look of your acrylic surfaces, acrylic sheets or other acrylic products (also commonly known as Plexiglass or Perspex):
1. Make sure the plastic really is acrylic
A clear plastic may not always be made from acrylic; instead it might be a polycarbonate. If the plastic is polycarbonate, it is will no longer possible to remove the scratches.
2. Remove light scratches from acrylic
You will need acrylic polish, preferably specialist acrylic scratch remover that is designed for industrial use, and grit sandpaper, 800 and 1200 grit. Wet the 800-grit sandpaper and run it over the scratch in a circular motion. Repeat with dry grit paper, and alternate between wet and dry sandpaper. It is normal for your acrylic at this stage to look frosty and to display little scratch marks on it. Next move onto 1200 grit sandpaper and keep rubbing until all scratches have been removed. Finally, dry the area with a soft, dry cotton cloth and apply acrylic polish. The acrylic will look as if it has never been scratched.
3. Remove deeper scratches
Deeper scratches can require a little more effort to remove, but you can still restore your acrylic sheet to an optimal condition. The method is similar to the previous one, with the difference that you need to start with 600 grit sandpaper and afterwards continue with the same process as described above.
4. Polish acrylic to restore its glossy look
Flame polishing is a great way of obtaining the smooth, glossy edges that we all like to see in acrylic cut to size. In order to complete this process, you will need a hydrogen-oxygen torch with a number 4 or 5 tip. Guide the flame over the acrylic edges, but do this very carefully as moving too slowly or too closely to the acrylic will damage it and bubbles will begin to appear in the plastic sheet. Overheating the acrylic can also make it melt, and going too fast can produce a matte aspect from the edges.
