Urethane and tire haze??

[BruceBe]

Hello all,

This is my first post - I am very impressed with the body of knowledge and enthusiasm found on this forum. Most of the garages and projects shared on this board are absolutely inspiring!

I recently finished the construction of a detached shop, and decided to go with a professional install of the flooring system, as it usually makes sense for new construction. We decided to go with a darker floor color (royal blue), since the overall light level is very good. The floor has an epoxy primer/base-coat, and then is finished with a Urethane top-coat.

We have noticed a hazing of the top-coat from the tires of parked vehicles. Some of the tires are very soft (e.g. race tire), and some are very hard (18 year old forklift). Both seem to haze the topcoat, and it is very evident with the darker color floor.

Is this to be expected with Urethane topcoats? I've had the manufacturer rep talk about "cheap plasticizers" that are used in tires, and interactions with Carbon atoms in the top-coat...blah-blah-blah. Has anyone else using urethane noticed this problem?

Any insight would be greatly appreciated!

It is called tiger striping and is caused by the chemicals in the tires. It shouldn't happen if they used a Hi perfprmance urethane. Known as HPU.

I have not seen these issues in our urethane glaze coat...

The manufacturer is Dex-O-Tex, and the system is Aero-Flor 100.

I was being told by the manufacturer rep that some hazing can take place, until all of the cross-linking completes, which can take several months. In the interim, I should be putting carpet (or something that doesn't have "cheap plasticizers" in it) between the vehicle and the floor. I truly have higher expectations of a urethane floor.

We are considering a different system, as the installer wants to make it right. Has anyone had experience with this particular product, or a candidate alternative - Tnemec?

Thanks,
-Bruce
