You Have Haze from Sealing Your Denver Granite Countertops… Now What?

December 30, 2015

So, you’ve either had your Denver granite countertops sealed or you just sealed them yourself and you’re experiencing a haze or film on the surface. It can be quite maddening and frustrating to see your brand new countertops looking terrible. It can be a shock. The first question you have is likely along the lines of how you clean it off. Before we get into that, first we have to look at how haze streaks after sealing can occur. Hazy streaks can occur after sealing for a couple of different reasons:
  1. The principle reason that your granite countertop is hazy or streaking is because they didn’t need sealing in the first place. Most of the colors in granite countertops are naturally dense and non-absorbent. This means most granite countertops cannot, and should not, be sealed. It actually doesn’t stop at granite. Many natural stones like travertine and marble don’t need sealing either. If you’ve seen something declaring all granite must be sealed, this is untrue. If a sealer is not needed, it merely sits on top without being able to absorb and instead leaves a hazy or streaky granite sealer residue. Finding out if your Denver granite countertop needs a sealant is by performing a water test.
  2. The water test is easy: Drip a small puddle of water onto your countertop, make a note of the exact time, and then do some astute observation. If the puddle darkens quickly then sealing your countertops is going to be required. If it takes four to five minutes to darken, then a sealant is still going to need to be applied and spills mopped up quickly. If it takes ten to fifteen minutes, you should still apply a sealer but it should also be done with the utmost care. One coat should last a few years. And, finally, if the puddle doesn’t darken or takes longer than thirty minutes, then you should never need a sealer.
  3. Another reason for hazy or streaked granite countertops is the result of a sealer being improperly applied. If your countertops do need a sealer but it was not applied correctly then the drying of the sealer will cause streaks. The most important step when sealing your Denver granite countertops is to ensure every bit of excess sealer and residue has been removed.
The bottom line is, you have the streaks and now you want to get rid of them. You're going to have to try and remove the sealer residue from the surface. Stone sealers are designed to remain on the stone for as long as possible and take several years to break down or wear away. You might have some lucky scrubbing with steel wool or a magic eraser. Do this on granite only. Such abrasives could scratch a polished finish on marble or travertine. In almost all cases, you'll have to strip off the sealer residue using certain solvents. The exact choice (acetone, mineral spirits, methylene chloride) will depend on how tough it is to remove.
