| Acrylic Polishing Guidelines |
The first step to producing an optically clear aquarium is to have a simple system to use. The system should be one that produces the desired clarity with the minimum amount of time and work. A plan to formulate a system is provided in each one of our Scratch Removal kits. The second decision to make is whether to polish wet or dry. These terms are not meant to confuse people as both methods require water. Wet polishing really is done under water and requires special tools, extra planning, and a great deal of time and effort. Why do this? This is the only way to remove scratches on the inside of the aquarium without taking all of the live goods and water out of the aquarium. Wet polishing is a great method for working on established reef aquariums, public aquariums or tanks that are just too big to break down. Dry refurbishing is done with wet/dry sanding methods on the outside or in an empty aquarium. This method is faster and easier than wet polishing. The next decision is whether to proceed with the restoration by hand or to use power tools. This is not a decision that should be made lightly and there are several questions to consider. First, are you comfortable with power tools? Have you used them lately? Have you used power sanders and buffers before? Can the area that needs polishing be reached with tools? Can air hoses and electrical cords be put into a safe area without falling in the water? You need to be comfortable with using power tools and understand what can happen if they are used incorrectly. The job will go easier and faster if done with power tools correctly, but it also requires additional preparation, care, attention and clean-up. Now that these decisions are made, it is time to choose the appropriate
kit. (kit comparison

If the panel is curved the pad must follow the contour of the panel. If you have chosen to use power tools you must hold a 3-4 pound machine, with abrasive disc attached, against the viewing panel and move it up, down, back and forth across the surface at a uniform speed while applying uniform pressure. Holding the machine at the wrong angle, sanding too long in one area or not maintaining a consistent sanding pattern will result in distortion. Putting distortion into a viewing panel is much easier than getting it out. When dry polishing, apply water to the acrylic regularly with a spray bottle. The water works like a lubricant which extends the life of the abrasives and reduces the amount of effort required. The water will also wash away the material being removed. When finished with each grit, clean the viewing panel to ensure that the coarser material is removed from the surface. This material will cause more damage if it is not wiped off. Use clean water and a cotton flannel cloth for this step. A good light source is also helpful when polishing. Aquarium lights should work great for working on the outside of the tank. The light will help to show if the damage is removed and if all of the prior scratch pattern has been replaced with a new pattern. Finally, lay out all of the materials in a neat and organized manner, leaving plenty of room to navigate properly. This step will pay off in the long run. Follow the instructions that come with the kit and don’t take any shortcuts. If you are patient and allow plenty of time to do the job, you will be very satisfied with the results. |
