How to polish self-levelling screed

To polish a self-leveling screed, you can follow these general steps:
 

1. Clean the surface thoroughly, removing any debris or dirt.

2. Use a coarse diamond abrasive pad to grind down the surface of the screed, starting with a low grit and gradually moving up to a higher grit.

3. After using the coarse pad, switch to a finer pad to achieve a smoother finish.

4. Rinse the surface with water and allow it to dry completely.

5. Apply a sealant or polish to protect the surface and enhance its appearance.
    

It's important to follow the manufacturer's recommendations for the specific self-leveling screed product you are using, as different products may have unique requirements for polishing and sealing.
