Step 6 – Clean Up with Denatured Alcohol
- Wait for the silicone to fully cure before cleaning up the leftover residue that is stuck in the texture of the melamine. This is easy to do by rubbing it away with your fingers and by using denatured alcohol.
- Pour water on the countertop and let it sit 10 minutes.
- Soak up the water, and if the surface has darkened, it isn’t fully sealed. Repeat Steps 2-4 until it passes the water-drop test and the surface doesn’t darken.
- When the countertop is fully sealed, the sealer can be burnished with diamond infused hurricane pads to remove any streaks or to adjust the surface sheen.
Step 8 – For Best Results
- This is the work of trainees, using the techniques described here for the first time. The little indentation in the corner is a common problem due to leaving bumps in the silicone. To prevent this, make sure that you apply the same amount of pressure on the tool when using it to smooth out the silicone.
- This sample piece has a cast-finish and is straight out of the form. The edges were meticulously looked over and finished by a fabricator before the pour began.
- The edges of this piece have been hand sanded with diamond pads. You can see the difference between the cast finish on the surface, and the exposed aggregate of the edges. Some small blemishes can be fixed, but re-profiling the entire edge by hand can be time consuming. Choose the right size tool for your project.
