Sealing Madura Gold Granite
(Chino Hills, CA)
We just recently had a new granite countertop installed called Mardura Gold. When we asked our installer, he said that it was already sealed but he would seal it again if we wanted to.
After sealing the granite, we noticed that there are some areas that looked dull and not as smooth. What can we do to bring back the shine to our countertop?
Also, even after he "sealed" it, I did the "water test" and noticed that the color became darker where the water was. Does this mean that the countertop wasn't properly sealed? HELP!!!!
Nice choice... I have madura gold in my kitchen!Well, if you noticed the dullness right after sealing
, then I'd have to say it's sealer that has dried on the surface. And why did he think it was already sealed?
Madura gold granite can be very dense and not require sealing, but some slabs may... it varies.When sealing granite
, you need to allow the stone to absorb as much sealant as possible, but the most important step is to completely wipe off all surface residue before it dries. If it dries on top you will get a dull haze. To try and correct this mistake
I'd apply more sealer to the affected areas, scrub with a soft-bristle brush and see if you can get the dried sealer to remix with the new wet sealer. Then wipe the surface completely dry. If this doesn't work
(you still have the dull haze), then you'll have to strip the granite sealer with either acetone or if really stubborn, methylene chloride.
And if you notice the granite getting darker under a puddle of water, then it is not sealed, or not sealed well or sealed with something that is not really a sealer.
However, it could be that the dried granite sealer is messing up the test. So, perform it on several places, especially where the granite looks normal shiny.
