UltraFiber 500 FAQs

Can you use UltraFiber 500 with color?

Yes, UF500 cellulose fiber accepts integral color better than any other commercially available fiber. It also will accept stains and dyes.

Can I use UltraFiber 500 in stamped or polished concrete?

Yes. It finishes smooth without fuzz or blemishes, making it ideal for decorative work.

How does UltraFiber compare to polypropylene or steel fibers?

UltraFiber 500 offers the same crack-resistance and durability benefits but blends in better than polypropylene and won’t corrode like steel.

Can it replace WWF (welded wire fabric)?

When dosed at 1.5 lbs. per cubic yard of concrete, UF500 can replace WWF for secondary reinforcement.

Is UltraFiber approved for structural applications?

It’s designed for non-structural reinforcement. Use steel reinforcement where load-bearing strength is required.

What types of projects is UltraFiber 500 best for?

It works in almost any application, including slabs, paving, precast, pervious concrete, curbs and gutters, architectural and decorative finishes, shotcrete, and more.

New Blog Post About the Absorption Rate of UltraFiber 500

UltraFiber 500 is incredibly hydrophilic by nature, meaning is readily attracts and absorbs water. This is in stark contrast to synthetic fibers - such as polypropylene fibers and glass fibers - which are almost universally hydrophobic, repelling water.
