How to repair porcelain/cast iron sink scratches

This is an under the counter sink installation and I do not want to remove the granite counter top to remove and repair the sink. Please advise best process to eliminate srcatches, dull spots. Most repair services in my area advertise a polymer spray-on process? Is there anything better?

If this does not work, is it possible to cut out the cast iron sink and replace with a new surface mount sink. If so how do I cut out the sink??

Look forward to your reply.

You can repair the sink with an epoxy based porcelin kit


Epoxy will not show brush streaks it will levelitself out do not get any kits from HD or Lowes they do not harden

Go to Sherwin Williams and ask for an epoxy paint for porcelin

As for removing the under counter sink
I would try cutting through the caulk adhesive
between the bottom of the granite and cast iron
sink with a hack saw blade
I have used a diamond blade on a grinder and
cut through but it was not a granite counter top
Be extremely areful to suport the underside of the sink with 2x4 blocks to prevent stressing the granite as you cut through
Good luck

Use comet cleanser to remove pot and pan marks. Unless they are deep scratches or gouging.

I would call your local Kott Koating dealer and have them re-glaze the sink with their Porcelain based K-40 glaze. It was specifically developed for this application and will make it look like a new sink. Plus, its not paint (epoxy or urethane) so it will last way way longer and be much more durable.

Will under mounted sink take the weight of garburator?


The sink should be physically mounted with clips if it is not cast iron, otherwise a cradle made of wood is usually the route I go.

There were no instructions to install my undermount sink. What can I do?


Most under mount sinks are installed before the counter tops go in, they are cut to fit and glued in with 2 part epoxys and secured with screws and clamps. Replacing one in an existing counter top is not an easy job. If you have a granite top, forget it. If it is wood and formica, ok, you can pull the splash off and remove the top, but it is a lot of work. You would be better off with a new top, or a new sink, rim type. Now if you are building a new house and this is new construction, then you can do it no problem. And depending on what kind of top it is, it needs to be screwed and glued. The guy here that did granite for us, would drill out little holes, about 1/4 inch dia, and 1/2 deep for these little machine inserts to go into. Epoxy them in, then clamp the sink down or up to the top with machine screws, about 10/24, 1/2 inch long. Through a clamp, and epoxy the top on, sometimes he used clear silicone. depended on the top. If it was wood, you would just screw into the wood with 1/2 inch pan heads. Hope this helps.

Will under mounted sink take the weight of garburator?


No the weight of the disposal will not separate the sink from the granite. When they set the sink they put wood on the edge under the sink to hold the weight of the sink. You will not have a problem.

Installing an undermount sink in case it need to be removed


under mount sinks are 'glued' to the underside of the granite countertop using clear silicone caulking. Clean both surfaces really good with alcohol or acetone (or even disc brake cleaner, apply caulking to bowl flange and position bowl up to underside of counter. Temporarily block in place and let cure for 48 hours. To remove bowl later, use a thin cutting blade like a hacksaw blade to slice through the caulking line. It helps if you don't squish all the caulking from between the bowl and the counter so that you can just get the hackwas blade in there in the future.

Pegasus granite, black kitchen sink, rough on the bottam


As a plumber I have seen this problem many times.

A very simple solution!!!!!!!!!

Turtle Wax or any kind of granite counter polish. CorStone (sp?) used to send me a polish/wax that worked wonders but I havent delt with them in a long time so I dont know if it is still available.

Just use try Turtle Wax but make sure not to get Turtle Rubbing Compound as that has grit in it which will scratch the surface of your counter.

Hope this helps.
