Help my neighbor! she's ruined her slate...

My neighbor came over in tears Sunday because she's afraid she screwed up when sealing her slate. I pointed her to the John Bridge forum, but offerred to help.

Here's what happened...
Brand new outdoor entryway - concrete platform covered with natural guaged slate. Grout is a medium beige color. It's been down for about 2 weeks.
She vacuumed the slate and then sealed it with Aqua Mix Ultra Sealer - Premium Stone and Tile Sealer. She applied it with a hand pump, covering the entire area (about 10x20). She let it dry overnight.
This morning, she wanted to add some "extra protection" to the grout lines and someone had recommended Benite Wood Sealer (here's a link to that stuff... http://www.dalyspaint.com/new_page_12.htm)
So she painted on the Benite just to the grout lines. Her paint brush was a little wider than the grout lines. Where the Benite hit the slate, it left it darker and a bit shinier - very obvious that somthing had been painted on there. These dark lines are on every grout line in the project.

After seeing her mistake, she poured this sealer on the entire stone on a 3x5 section and now that stone is sticky and has some sheen and some actual gloss.

She is horrified and in tears!
What can she do to restore her beautiful slate entryway?

on Monday she went out of town so it's just been sitting there...

Thanks so much for any advise! Diane

I think we answered this thread as best we could before by suggesting she contact the manuf. about stripping the product.You can't grind the surface of layered slates, but you can chip away at the clefts to reveal new material...BUT this should be done by someone with experience...a restoration specialist, maybe.If the slate is compact he may be able to(after stripping)an bringing the ph to neutral grind the surface down to clean stone, and apply a legitimate stone specific enhancer.

Hi Diane

It sounds like the slate needs to be stripped. Can you post a picture?

Depending on the content of the sealer, will establish what can be used to strip it. We always suggest TESTing in a small area first.

Sometimes reapplying the same sealer will break it down, but the way you are describing it, I think there is too much sealer on the surface.

Could you tell us exactly which product was used? There are too many on the site to guess from.

The sealer is called Benite Wood Sealer. Daly is the store name here in seattle and it almost looks like a local brand. That's all I know about it. I'll check with her later today and see if she's made any progress. thanks, diane

Hi Diane

If you go to their site with the link you provided, there is no such product.

Hi Diane

Thank you, that helps a lot!

I suggest she applies some denatured alcohol, lacquer thinner, or acetone on a rag, and rub in an inconspicuous spot. See if this removes the over application of product.

Use extreme caution, as these products are flamable. Also appropriate safety equipment should be used (safety glasses & solvent resistant gloves).
