Home Concrete Slab With Fiberglass
I added this fiberglass to my concrete mix for a slab that was 3’W x 17’L x 4”D and it worked perfectly and made it super durable….

Perfect addition to Bondo or fiberglass resin.
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.

Excellent shredded fiberglass for added concrete strength
This shredded fiberglass mixes well with most all concrete products and does not clump up. Really adds an extra level of durability and strength to concrete installations. Recommend this product. In some cases there is no need for rebar if the concrete application is suitable for this alternative.

Fantastic FibreGlass product. I will order again
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.
