Small damage on a sink

Step 1: 
We work with the Repair Kit - Ceramic Sanitary Ware. The area to repair has to be clean, dry and free from grease. If necessary, remove any loose or sticking out particles. TIP: Clean with alcohol or thinner. Remove discoloration at edge with the sandpaper or (tooth) brush.
Step 2: 
Remove the black cap from the Ceramic Filler. Attach the cannula firmly to the syringe. Apply the filler directly into the damaged area until area is slightly overfilled.
Step 3: 
Place the clear filmstrip directly onto the filled area. Use the wooden spatula to flatten the filling material. Make sure no bubbles will develop under the film.
Step 4: 
Cure the flled area by illuminating for approx. 5 - 10 minutes per cm² from a distance of not more than 1 cm. Curing time varies dependent on coat thickness. NOTE: If the filler no longer hardens, please replace the UV Lamp battery. IMPORTANT: Do not look directly into the LED Light, as this may lead to permanent eye damage.
Step 5: 
Remove the clear filmstrip when filler has cured.
Step 6: 
Use the Special Sandpaper to sand off excess material in a circular motion with light pressure until level. NOTE: Ensure not to sand through the filler!
Step 7: 
Apply a small amount of polishing paste to the repaired area and rub in with the cotton cloth in a circular motion using light pressure until the seheen matches the surrounding area. Clean away any polishes residue with a dry and clean part of the cotton cloth. Done! IMPORTANT: With damage of more than 1-1,5mm depth, it is necessary to work with several layers. Prefill and harden the damaged area (please see step 2-4) and repeat process.
