  • a dry cotton cloth or cotton wool, which is available for only a few euros

  • Acrylic filling compound for sealing and surface approximation - costs between 8 Euro and 15 Euro
  • Spatula - cost about 2 Euro

For superficial scratch removal, thoroughly clean your acrylic bathtub. Reliably remove grease deposits and dirt edges. Then dry the surface.

Tips: If you use filling material with deep scratches, this is ready as a spatula product or as a powder for mixing. On a product for self-stirring should abandon mainly artisan layman. If the ratio of water putty is not correct, there is no long-term repair, the mass sticks poorly and dissolves over time. Prefabricated tubes with filling material for surface indentations are particularly suitable for scratch removal and, if necessary, also fill cracks.

Step 3: Then let the acrylic polish dry completely.

Step 4: After about five to eight minutes, also rub the polish in a circular motion, with a dry cloth or polishing pad, until completely removed.

If not all scratch marks have been removed, repeat the process one or two more times, increasing the pressing pressure when applying the acrylic polish in circular motion.

Step 5: Finally, remove last polish residues with water.

Deep scratch removal with filler

Step 2: Using a spatula, spread the filling paste over the scratch edges and the sanded environment.

Step 3: Allow the filling material to dry well - exact drying times can be found in the instructions for use of the filling compound - which can be up to 24 hours, depending on the product. Ensure that the filling material dries completely by pressing lightly on the finger before continuing.

Tips for taking care of an acrylic bathtub

... after a scratch removal and preventing new scratches

Basically, when cleaning an acrylic bathtub should be dispensed with aggressive detergents and coarse scouring powder. It is recommended to clean acrylic baths after scratch removal with surface-friendly cleaning agents and not to use too rough scouring pads. These can leave traces of sanding, which subsequently show up as unsightly scratches.

For further care and for coarse dirt and lime deposits, it is advisable to treat an acrylic bath regularly with acrylic polish or special acrylic cleaners. This not only cleans the surface, but also removes traces of scratch already visible to the eye and places a protective film on the surface of the bathtub. This keeps the surface supple and reduces the risk of scratching again. In addition, special acrylic products for care and cleaning lead to color refreshments of old, faded bath coatings.

Remove jewelry before each bath and avoid using the bathtub rim as a coat rack. Trouser buttons or belt buckles quickly ensure new scratch marks.
