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

Q: Are the fibers AR fiberglass (alkali resistant) ?

I made hypertufa pots with the fibers in the mixture since they are glass fibersI believe they are alkali resistant

Q: Will this work with self leveling cement?

First if your using self leveling cement you most likely are and should be covering it with tile or some type flooring. It should not really need the fiberglass fibers for strength since it is getting covered up. It is possible it will work but don't use a heavy amount. I would try a small test spot on a piece of plywood or somewhere. See what other answers you get back also, or ask the seller too

Great for making hypertufa stronger

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.

Good quality but pricey

Does what it is supposed to. A little pricey if you are just buying a pound like I did.

Works well.

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.
