It was a pleasure speaking with you yesterday and getting additional direction about the NuVibrants application. 

  • I used a kitchen bristle brush with the deposit remover that seemed to be effective.
  • I spray-applied 2-coats of the NuVibrants and smoothed out the runs with a new soft sponge
  • Allowed both coats to dry (approx. 1hr each) completely
  • I then applied the Granite Quartz & Marble Treatment with ioSeal  


Before, During, and After Pictures

This before picture shows what the sink looked like prior to starting the restoration repair. 

The side walls were smooth, but the bottom of the sink has texture from harsh chemicals that were used in the past. You'll notice there is a slight chalk-like haze in the sink.

Voice of the customer: As stated, the sink bottom had a rough texture, unlike the side walls which were smooth.

The initial results appear to be satisfactory. Time will tell.

Understand periodic cleaning with the Granite Quartz & Marble Treatment will be needed to prevent reoccurrence from the hard well water deposits.

    Previously bought your composite sink kit a year or so ago and after speaking on the phone you recommend we get a product called 511 Seal & Enhance to get the shine back in our sink.Needless to say not many people sell the 511 product anymore or it is only available in large quantities. I like your cleaner and preserver and have plenty left. Is there a way to just buy the NuVibrants product alone?
