Morning dew and coatings, does it matter

**MrOneEyedBoh** · 03-23-2019, 01:25 PM

I was just wondering and couldn't find anything via searching, but say you apply the coating the it sits 5-6 hours then gets hit with some dew. Do you think that hinders the coating? Most say no moisture for 24 hours...

It is possible. I once tried using CanCoat and it was exposed to dew overnight. The hydrophobics took a hit as the water beading and sheeting were lacking.

Not a coating though but happened for me with Ultima Paint Guard Plus. It's has a curing time before moisture can be on it. But the dew came in right away after application. The next wash the water layed flat.

And I think that SiO2 in it nature absorb water. So as guz mentioned what happened with CanCoat you can experience it could make a dent in the hydrophobic top layer of the coating.

IMO:
The main “hindering”, (that may occur if
the Coating were to get hit with some
dew/moisture sometime during the initial
24 hours waiting/(curing) period,) would be
that the Coating just might not be able to
achieve the ultimate/maximum level
of its performance characteristics.

Apply it first thing in the morning and let it bake in the sun all day.

Edit: You could also apply the McKee's 37 10 minute paint sealant before the day is over.

This would be a great thing to do. For makeing sure you get the most out of your coating application.

Sounds crazy but this is the biggest reason im considering making my garage door openings higher.... To fit my truck in so I can let it cure "indoors".

I was just going to say it's pretty hard to do all this polishing coating stuff outside. You need a day that's dry but not sunny. And not going to create dew overnight. I'm lucky I have a garage to use otherwise I wouldn't be able to do most of the stuff I've done polishing wise.

I was considering getting a storage unit big enough to detail in if the day ever comes when I don't have access to a garage. At the very least I need one of those covers I forget what they are called. It's like a tent but even then that doesn't really stop everything.
