Removing year old Fusion Pro grout sealant from Porcelain


We have a huge mess on our hands that we have spent months trying to get to the bottom of. We had our 12x48 matte porcelain plank tiles installed over a year ago with Fusion pro grout. The tile looked great for months and we didn't even realize we had an issue until after months of cleaning I noticed I was getting blotchy areas (clean either with hot water, or water/vinegar mix). Most of the tiles had a shine to them, and then there will be a big dull patch. I tried every mop on earth thinking it was something I was doing wrong and then I finally had a stone company come out and explain to me that it is the sealant that is mixed in with the fusion pro grout that is all over my tiles! Our tile installers came back and tried scrubbing with Aqua mix Seal and Grout remover, which did nothing. I have had multiple floor restoration companies come out over the past few months doing test areas and nothing they use seems to help (usually a stripping agent). Any one else ever deal with this? I'm embarassed that it took so long for us to figure out we had residue all over our new tile, but it really did look nice and uniform once installed. Please help. Stephanie

Your list of resources is impressive, however one you did not list is the one resource that can likely give you your very best answer. If you have not already, give custom building products technical support a call as they would know THE answer. Good luck.

Fusion Pro grout is acrylic based, sticky to the point of slimy, and dries, as we say in Boston 'wicked fast'.

So it's very easy to end up with serious grout haze if you treat it like cement based grout, like regular stuff.

We've used acetone on a cloth to get off the haze if it's been less than a few hours. Highly flammable, not recommended for large area. Gloves, open windows if you do try.

What strips acrylics is typically high alkalines like wax stripper and black nylon pad. Plan B is methylene chloride paint remover, but EPA recently banned it again.

Dwell time, allowing it to sit on the tile for several minutes before scrubbing, is required for all of these.

It's conceivable that if the haze is bad enough, cleaning efforts might damage or discolor the grout lines. If so, they can be recolored, Fusion Pro takes color sealer just fine.

Razor blade might speed up the job.
