Trusted by professionals, it requires just a slight adjustment in mixing time and dosage for superior structural performance.

## Description

Product description Crack resistance frost resistance impermeability impact resistance Glass fiber added to concrete plays a role in avoiding the occurrence and expansion of cracks, improving the impermeability of concrete, improving the freeze-thaw performance of concrete, improving the impact and willfulness of concrete, and increasing the service time of concrete. UPTTHOW Glass fiber is a material composed of many extremely fine glass fibers, generally with a diameter of more than 3 microns. Stabilizing structure Good dispersibility Not easy to corrode Use in multiple scenarios Suitable for compounding with resin Fiberglass Glass fiber can withstand high temperature, is incombustible, is not easy to corrode, has good heat insulation and sound insulation, high tensile strength, and good electrical insulation. It is used to make cement, ceramic products, and concrete to enhance rigidity and hardness. Transparent and light permeable High tensile strength, low elongatio Good continuity with various products High elasticity coefficient and good rigidity Non combustible, good chemical performance Wall painting Mix sand, cement and glass fiber evenly, then add an appropriate amount of water to stir to improve the high temperature stability of asphalt concrete, suitable for interior and exterior walls. Road construction Reinforced concrete with excellent anti-seepage and anti-cracking inorganic fibers, firmly fixing the cement, low temperature crack resistance and prolonging the service life of the road surface. Wall clearance Mix glass fiber and mortar together, the irregular distribution of glass fiber in the mortar enhances the toughness of the mortar, and it is used for wall stacking. Reduce fine cracks.

Review: 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.
Review: Works well - Works great binding curbing cement.

## Features

- Anti-cracking: Mixing fiberglass and mortar together, the irregular distribution of fiberglass in the mortar enhances the toughness of mortar, and inhibits the formation of fine cracks
- Waterproof and Impermeable: A large number of fiber filaments increase the density of cement, which can effectively solve the problem of penetration. It is very suitable for wet place such as basements, pond, Exterior wall
- Impact Resistance: High-strength fiber filaments are attached to each other as a dense net to hold the cement tightly. It can effectively enhance the impact and seismic performance of cement
- How to Use: Evenly mix sand, cement and fiberglass together, then add an appropriate amount of water, and finally stir (the stiring time is 30-60 seconds longer than without fiberglass)
- Dosage: Use 1 lb. (1 pkg) per cubic yard (27 cubic feet) of concrete. You can add a little more in the area with strong impact or severe freeze-thaw

## Questions & Answers

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