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

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.

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

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
