The Truth Finally!!
From a chemist telling you why Gel Coats Fail!

I had a very interesting and informative conversation with 2 chemists’ Mr. Jay Lampert and Mr. Jim Luke that work for Interplastic. Interplastic is the world’s largest manufacturer of resins and gel coats. Interplastic owns NAC the distributor in Mays Landing, NJ who sells their products to Uglassit. When I called I told them I was Premier Restoration, a pool contractor considering fiberglassing old pools. I was looking for a thick quality gel coat that would hopefully last 10 years, and one I could give a five year warranty. I was told that this might be a very foolish thing to do considering no one in the pool industry they know of offers a warranty on any gel coat for a retro fit on an old pool. They went into great detail on why all gel coats fail within 2 or 3 years, by first chalking then blistering and flaking.

They told me why gel coats last 10 – 20 years for newly manufactured fiberglass pools, slides and Jacuzzis. If you read my website it goes into great detail about the longevity of gel coats which could last 20 years or better on newly manufactured one piece fiberglass pools. These gel coats for new manufactured fiberglass pools are put on a mold, which is the shape and size of the pool. The application of fiberglass is then sprayed or hand laid on top of the gel coat of the mold. Using this method the gel coat cannot extotherminate (over heat).

You now have the names of these chemists and phone numbers. I would hope and I am sure Bill Nash of Uglassit would hope you would not call these people.
I asked them if they would e-mail a letter stating these facts. Corporate Policy would not allow them to do so.
They are now finally testing to see if they can manufacture a retrofit gel coat for old swimming pool containment but it can take years.
