Kitchen : Tips

I have been using postform top for kitchen top in my old flat for almost 8 yrs and it still look good when I sold my old flat.

How to avoid the water to seep into the egdes of postform top for kitchen:

1) Top mount the sink and put a thick layer of silicon "under" the sink (Before the edge).
2) To coat a layer of clear color paint at all the 4 edges.
