The strip exposed to the sun....

[Printer Mike]

Please excuse if this has already been discussed....

Several years ago, someone gave me an estimate to do my garage floor with an epoxy coating. I believe it was a Rustoleum product.

I remember the estimator noted that the small strip, outside beyond the garage door, would not be guaranteed due to UV (sun) esposure.

Anyone heard of this? Is it inherent in all coatings?

I work with my door open quite a bit. After 5 years, you can tell the front is a different shade than the back. I noticed it when I mixed up new paint to touch up a spot on the floor from where I moved a wall. The paint matched perfect in the back, then I spilled a drop in the front, and the shade was off.

Considering I wouldn't have caught on otherwise, I don't really care.

Even if it does change shades, does that little strip make a difference? If it bugs you, put a metal strip over that area where the seal goes.

Edit: I have Valspar, but I would assume it's the same.

Perfect reason to use another product besides epoxy. We have moved to polyaspartic polyurea coatings instead of epoxy . . . one reason is their UV stability.

UV instability is one of the downsides of epoxy - it will yellow.

Well Wolverine was talking about a hydronated (sp?) epoxy that has better UV resistance, not 100% but better. But that is the nature of the beast we call epoxy, sun is its kryptonite.... and other things. Polyaspartic is the future... its really not that expensive, unless you find a company that goes through 3 other companies to get it. Gotta find the direct source....

I can live with color fade.

I'll pick a color that looks faded to start with.......lol.

perhaps more chip coverage would minimize the yellowing (unless of course an epoxy clear is used).

oh man, more digging on epoxy. We include a UV protectant in our installations.

I guess time eventually wins that battle, though.
