Remove the old material. It should be silicone. If the joint is tight you may need a razor blade to get it out. Use a tooth brush to clean with alcohol. When that has evaporated apply...

Corian is a mixture of natural mineral (ATH) and acrylic resin. It would be inappropriate to usa a polyester to repair it.

Harold is right .

If you find that it is not the same as you sand it is not Corian.

bshowto,

I agree with Harold. The replacement of the sink alone is done. Some fabricators will do it in your home. The cost will be about $1,500.00. Call DuPont at 1-800-426-7426 for repair...

First support the piece to be removed so that it does not crack as you finish the cut.

You can cut back to about 3" from the back splash with a circular saw. Corian is no harder than rock...

Irony

Is this an undermount sink? Undermount sinks and 1/2" Corian are both rare in 22 year old motor homes. Your answer will help me answer your question.

I think that you will have to send a picture. There are many kinds of connections.

Pattyg2,

The duPont piece seems a little confusing though accurate. It has a lot of options.

The eHow piece is badly written. The author never completes a thought. It is also quite wrong.

There are a lot of unknowns here.

What grit did you use. Very fine does not define it.

Another unknown is what your luster was. This is tough to tell verbally.

Typically a satin finish...

First of all, know that it is just on the surface. Corian is non porous so the stain is not imbeded. First I would use a product like CLR or Lime Away. These are mild acids which disolve lime...

It sounds like your ring gear on the fly wheel.

With the key off, turn thr rngin by hand a few degrees and it will probably start. If it starts, one or more teeth are broken off the ring gear. ...

Professionals will not repair a sink. They have been told that it is impossible and the repair is not worth their time.

Thanks for pointing out what a dumbass thai I must be. I had thought that I had seen tham all. The overflows that I have seen have all been made of Corian. This looks that some...

I agree with hkstroud, about the silicone.

The sink however is not Corian. It may be Solid surface. And the top is Corian but duPont never made sinks this way.

Ken

Retiredguy,

I am not familiar with Daps Qwik Seal Plus, but if it is not 100% silicone I would not use it.

Clean out all of the old material. Then apply the new, with the tip 90 degrees to the...

I am sorry that I did not get here sooner.

I dissagree. While a proffessional job may be better, it will take several hours. Properly done it will be over 2 days. The cost is usually around...

In addition to what has been said, a green Scotch Brite pad or some soft scrub should take almost any "stain" out of Corian. A true stain is something absorbed into the material and this usually...

First call duPont at 1-800-426-7426 (1-800-4CORIAN) and ask to have a waranty inspection. If the sink is Corian and faulty they will have it replaced. It has a 10 year waranty against...

I know that duPont does not authorize any method of repairing a Corian sink.

However we have supplied a kit for doing just this for 15 years. Hundreds of people have used it and had...

Two more things:

1 Make sure that yousand the cut as smooth as the top. This will eliminate any "stress risers".

2 Apply some metallic tape to the edge of the hole all the way around. ...

Do not be tempted to make a sharp inside corner as that will be a stress riser. That is a place where a crack may start. Allow about a 1/4" radius.

Go slow and take a little off at a time. You...

There should be no clear coat on a Corian countertop.

Kingerna,

You have had good answers but I always recommend cutting at no faster than 60 Inches per minute. Your cut will be much better and it will cut down on the dust.

If it is Corian it did not yellow. The closest color in Corian that I can think of is Olive Mist. This color was discontinued about 1991. It had a few olive veins in a off white back ground. ...

A good quality automotive paint will coat Corian very well. It has a similar chemical make up Acrylic. It is just like putting on another layer of paint on a car.
