Looks like too much was applied, which sometimes leaves that milky colored coating on sealers. I don’t know, I wasn’t there, just have seen this when people over apply sealers. When you applied it did you wipe off the excess with a rag/cloth? Not several hours later, these things have a quick kind of surface dry then they fully cure in a couple of days.
edit: went to their site and this is what they say
3. Allow Sealer to penetrate surface for 15-20 minutes. Denser
material may require more time to penetrate. DO NOT ALLOW
EXCESS SEALER TO DRY ON SURFACE. Failure to remove
excess sealer from surface may result in residue that may need
to be mechanically removed.
4. Thoroughly wipe surface with multiple dry cloths to remove all
excess sealer.
You used this on flagstone, which is normally quite porous/absorbent.

I have no issues with DIY people I’m one myself.
I give out about 10 quotes a month to strip and reseal DIY or hack job work . It’s always the same story.
My quote to seal $1500
They decided to do it them self with cheap crap for $250
6 months later when there tired of looking at a ugly deck that looked better before they messed with is now $3000
Anyhoo, I’m going with to much sealer applied to quickly and the excess allowed to pool. We see it with coatings like exposed aggregate sealers and especially coatings like rexthane. I’m not familiar the the exact type he used but the silane/siloxane coating will absolutely cause you issues if you dont follow the correct application procedures. We dont even sell it to homeowners any longer. Only pros who we hand hold through application.
I wasn’t judging you. I read it, said Dam, then started laughing. I was just laughing again when I re-read it.
What makes it funnier for me is that there is a politician by that name about a county or two away from me. The thought that dude checks in to think that someone gave him the solution and reads that response with the thumbs up at the end…I’m laughing again.
@florida_condo_cleani knows @Dirtyboy , That wasn’t towards you. Harry homeowners come on here alot to try to get advice to do it themselves to save a buck, then leave with nothing to contribute.
