【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

Please note that 2lb are packed in one bag
