How To Remove Scratches on The Surface of Acrylic Artificial Stone ?

To remove scratches on the surface of acrylic (PMMA) or acrylic artificial stone, different repair methods need to be taken according to the depth of the scratches. The exact actions are as follows:

1. Minor scratches (such as minor surface friction, shallow surface scratches)

2. Dental wipe: Apply a moderate amount of non-gel toothpaste (or plain white toothpaste) to the scratches. Gently wipe in a circle with a clean pure cotton cloth or a soft brush. Repeat several times. The scratches will be reduced or disappeared and the surface will restore luster.

3. Gentle cleaning: Mix warm water with a small amount of detergent and gently wipe the scratches with a soft cloth. Decrease the scratch by repeated wipes. II. Deeper scratches (e.g. scratches that can catch your fingernails, obvious scratches) 1. Water sandpaper polishing: Choose a different number of water sandpaper (e. g. 800, 1000, 1200, 2000) to polish according to the depth of the scratch. Apply water (water grinder) when grinding to speed up and reduce dust. Gently grind the scratch until the scratch is smoothed and transitions smoothly with the surrounding surface. Pay attention to the gradual transition from rough sandpaper to fine sandpaper to avoid excessive grinding causing surface depressions.

4. After polishing: After the polishing is complete, rinse the surface with water, dry the surface, then apply polish wax or polish ointment, polish with a soft cloth or polishing machine to restore the surface luster. III. Large scratches or severe scratches (e.g. large scratches, severe abrasion)

5. Machine polishing: use electric polishing machines (such as cloth polishing machine) with polish wax or special polishing cream to polish and finish. Care should be taken to control the polishing machine speed (recommended 1000-2000 rpm / min) to avoid excessive local friction causing burning of the acrylic surface or orange lines.

6. Professional repair: If scratches are extremely deep or large, it is advisable to seek a professional repairman to refurbish them using a professional grinder and polisher.Note: · Pay attention to the force when polishing and polishing to avoid excessive polishing that causes a surface to sag or damage the acrylic surface. · Before polishing, be sure to clean the surface to make sure it is free of dust and oil so as not to create new scratches when polishing.
