Fiberglass for Cement Mortar Concrete Reinforcement Anti-Seepage and Anti-Cracking Cement Mix for Building Walls Garden Floor White 3/4"(19MM)-4lb/Pack

Perfect for adding to Bondo for extra strength. As a taxidermist, I add it to Bondo to make thinner ears in the animals that I taxidermy. It does a great job.

worked well; not to fluffy, be sure to add a little at a time, or it clumps up will buy again if required

If you want an easy way to make concrete stronger this is what you need!

The strands are a pain to pull apart enough so you get a decent mix without clumping. Quality seems decent

Great product for cement pot making.

Very easy to use, and resulted in a great “cobwebbing” effect in the slurry once poured

I used to strengthen my hypertufa pots and it worked perfectly!

Easy to blend in to the cement. Just sprinkle it into the dry mix and blend dry first, rather than throwing in a handful or dumping in the whole bag after you add the water. You'll also need to add more water than usual. Concrete seems very hard with the product added.

Strands too long, does not mix well with cement

Absolutely what it says. I ordered what I got. I made a mistake thinking it was 5lb but it was actually 4lb. I am so sorry. The cut is good and the weight is correct. I will be ordering more in the future.

Tres bon produit

Quick delivery. Expect it will work perfectly.

a bit short, it's fine
