Review: A little goes a long way. - I make small cement items such as alligators and stones. The stone molds that I use simulate natural stone and parts of the mold are thin. I am concerned with the possibility of the stone edges breaking off. I don't worry anymore when using these fibers. I have had great results and stress tests on the stones have proven the usefulness of this additive. Keep in mind...a little goes a long way. Use sparingly for best results.
Review: Concrete Fibers - This will help keep your sidewalk projects from cracking. Mix them up well. I usually put two 60 lb sacks of redi-mix in my small mixer with .57 oz of fibers. I put the fibers into the mixer between the 2 bags of Redi-mix. Occasionally a small glop of fibers (like 1/8 ") will appear on surface of concrete while finishing. Just knock it down under the cream. I put 10 yards on concrete in my backyard with these fibers and you don't see the fibers anywhere. Why would I do 10 yards of cement with a mixer? I am retired. I have plenty of time but not money. Great Product.

## Questions & Answers

**Q: How do you get it to disperse evenly throughout the mix?**
A: What are you mixing it in? I mixed a handful in an 80 pound bag of cement with an hand-held cement mixture.

**Q: Does this work with plaster?**
A: We see no reason that they would not work with plaster.  Be sure to use these fiberglass fibers as nylon fibers might float to the surface and give you a 'hairy' finish.

**Q: Is it ok to mix these fibers in the concrete and use rebar**
A: I am not a concrete expert but I added it to a hearth I was making and used chicken wire too. Make sure the fibers are not on the surface.  They will look unsightly.  I can't see why you couldn't use both.

**Q: Why does this product take two months for delivery and the other one u have listed takes a few days?**
A: Ask Amazon.

### ⭐⭐⭐⭐⭐ Glass Fibers, great for reinforcing plaster, concrete, etc.
*by S***E on July 14, 2017*

Glass fibers. I'm using these to reinforce plaster of paris and it's working very well. It takes very little. I used 10% by weight the first time and I couldn't even mix the stuff completely because I couldn't penetrate the solid "woven" mat of fibers that formed as I mixed it. My only complaint is that they come in little bunches of fibers, about 1/8" wide. I prefer individual strands; so I break up the groups before use.
