It’s good but IMO Seal n Shine is easier to apply and also seems to shine and resist dust much better.
Layering Griots 3-in-1 Ceramic
- Thread starter Douglas007

Layering can work after setup but before complete curing. It improves the density of the film build. The problem is no one knows when this magic time period is for Griot’s 3-in-1. It is typically an hour with a bottled coating. Of course it depends on chemistry and diminishing returns apply.

During the set up, ScottHD followed manufacturer instructions for application. Some give instructions on wait time, others don't give any information for layering. Griots did not.
Here is the application (first video in the series):
I've heard layering described as 1 + 1 = 1.2. Second layer can also help if you went too light in certain areas on the 1st layer.
Griot's held up well in Scott's test. I like the beading of Sonax products. Even BSD to this day is top notch. Sonax Ceramic Sealant is very hydrophobic too.

He only waited 1 hour each coat. I think this is probably why…
I think it will have to be shorter for a product like Griot’s. These sprays cure fast. I tried this with Fireball Pirouette on an acrylic shower mirror and I got noticeably better (insane) hydrophobics with two layers after about 15 min. I use this mirror kind of as a test and waiting longer didn’t seem to help and made it worse, but I wasn’t able to get that same result again without polishing it for whatever reason. Pirouette is a solvent based product not water based like Griot’s so I wonder if two layers actually works better or worse because of that. It’s possible water based products don’t layer well because the carrier can’t “wet” the surface.
Nope. For optimal performance it needs to be cured 24 hours.
I meant for layering as in a second layer after the first. The majority of curing occurs quickly. Especially compared to a bottled coating. For layering you do not want a fully cured surface.

Yes, I was talking about layering. I did emailed Griots and they stated before applying the second layer, allow it to cure at least 16-18 hours. This is coming directly from customer service.
That’s contrary to the advice of almost every other ceramic spray / coating and what basics I know of polysiloxane coatings.
The reason to apply a second layer before the first is fully cured is that it creates better chemical bonding between the layers. When the first layer is still in a partially cured state, its surface contains reactive sites that can form chemical bonds with the fresh material in the second layer. The first layer needs to reach a point of curing where it's no longer “wet” but hasn't fully cross-linked.
This creates a more dense film build compared to applying a second coat on a fully cured surface. Also, with Griot’s 3-in-1 being a water based coating, if you allow it to achieve full hydrophobicity it will be harder to carry the additional coating to any site it can bind to.
I suspect you got a canned or not well-reasoned answer. Try it both ways on a test spot or panel and see, perhaps they are correct.
