Fiberglass for Cement Mortar Concrete Reinforcement Anti-Seepage and Anti-Cracking Cement Mix for Building Walls Garden Floor 3/4"(19MM)-1lb

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.

Works great binding curbing cement.

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

Fiberglass was exactly what I needed for faux rock making-- fast delivery!

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.

I have not used it yet I am waiting for the weather to warm up, I plan to use it to parge some walls were we poured some concrete last fall.

Great product for cement pot making.

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
