Colorless transparent acrylic sheets have approximately 92% light transmittance. They provide clearer visibility than glass, which means even the smallest scratches can be noticeable. Acrylic surface imperfections on the dry side should not be sanded unless they are too deep to be removed by abrasive polishing and buffing. If sanding is required, it must be carried out very carefully to avoid overheating or burning the acrylic surface.
In dry-area and underwater acrylic polishing processes, the depth of the scratches is first assessed to determine the appropriate grit of sandpaper to be used. Afterwards, a gradual sanding process is carried out using progressively finer grits, followed by polishing and buffing stages to restore the acrylic surface to its original clarity and smoothness.
Underwater acrylic polishing is the process of smoothing and restoring the shine of acrylic surfaces used in underwater structures such as underwater windows, acrylic aquariums, and diving panels. This procedure aims to improve both the aesthetic appearance and functional performance of the acrylic material.
Harsh underwater conditions can cause acrylic surfaces to become dirty, worn, scratched, and dull over time. Polishing minimizes these negative effects, helping the acrylic regain its clarity, smoothness, and durability.
Benefits of Underwater Acrylic Polishing
Aesthetic Improvement: Polishing makes acrylic surfaces appear clearer, brighter, and more transparent. This is especially important for transparent materials such as underwater windows.
Increased Durability: Removing surface scratches and imperfections helps the material become more resistant to wear and damage.
Easier Cleaning: A polished surface reduces the adhesion of dirt, algae, and similar substances, making cleaning and maintenance much easier.
Underwater acrylic polishing is a vital maintenance process for acrylic materials used in diving windows, underwater aquariums, and subsea structures. It extends the lifespan of the material while providing a cleaner, more visually appealing appearance.
Over time, acrylic panels may develop scratches, haze, or surface wear that affects visual quality. Pruva offers professional acrylic polishing and restoration services to restore panels to near-original clarity—often without the need for replacement.
