Glass fiber reinforcement in thin slab mix???

Drake and Steve,
I should have specified the polypropylene fibers are so small I cannot measure the diameter with digital calipers. They look like very fine cigarette filters, IMHO, and do not stick up in the floor. With an ounce per 6 cubic feet, there are billions in the mix. That's why they work well to prevent cracking with reduced water. Concrete companies don't normally have fibers so small. You'll have to get them from a supply company.

The polymer in leveling compound will bond well with concrete. It contains VAE too.
