Polyaspartic floor installation questions

[Fish-man]

I'm having my floor done with a polyurea-chip-polyaspartic system. They are saying I can walk on it in 6hrs... and drive/park after 24hrs.

My first question is what is the problem with parking ... is it the rubber interaction, or the weight?

I'd rather not leave my nice cars outside overnight. So, my second question would be: couldn't I lay down some 2x12s and park on those the first night (after the 6hrs)? It would alleviate the rubber on the floor, as well as spread the load over a larger area?

Has anyone done this? What do the GJ flooring pros say about the idea?

Thanks

I use 100% solids polyurea as a top coat on damn near every floor I do. My experience is at least 24 hours is needed before walking on the floor without leaving foot marks. I'm applying at, say, 12-16 mils. A thinner coat will most likely cure a bit faster, although not much more in the grand scheme of things.

Lower temps and low relative humidity mean a slower cure. Higher temps and high relative humidity mean a faster cure.

Regardless, I wouldn't be pulling cars to park onto that floor for a few days. Maybe their product is a fast cure, even then, I'd be wary.

I personally wouldn't park on wood planks, my fear being it will leave a long flat mark permanently on the floor. It's not an issue with rubber, has to do with the weight. That coating is still soft, I'd give it minimum 48 hours personally.

You can always check if the coating is soft by pressing a finger or knuckle into it also. IMO, it's just best to wait a few days. No sense in ruining a floor you just had installed because you didnt let it cure properly before parking on it...

Agreed, a few days for cars.

You will be fine after 24 hours we do it all the time

I'll stick to whatever my installer says for time... was just hoping someone had a work around that has been effective.

In some plants we allow fork lifts in 8-10 hours if the conditions are favorable, and if they are extremely gentle. But if you can wait the better.

The longer you let the product cure on the floor, the less resistant it will be to marks from tires on it too early.

The stuff you had applied dries/cures much differently than stuff most of us are used to.

Which product do you all use and @ what thickness?
