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 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BX8P982L | | ASIN | B0BX8P982L | | Best Sellers Rank | #28,897 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #23 in Contact Cements | | Brand Name | UPTTHOW | | Color | White | | Customer Reviews | 4.6 4.6 out of 5 stars (353) | | Customer reviews | 4.6 4.6 out of 5 stars (353) | | Date First Available | 16 March 2023 | | Grade Rating | Residential | | Item Diameter | 0.75 Inches | | Item Form | raw | | Item Shape | Honeycomb | | Item Thickness | 19 Millimeters | | Item model number | JIN-Fiberglass 19mm-4lb | | Manufacturer | UPTTHOW | | Manufacturer | UPTTHOW | | Material | Fiberglass | | Model Number | JIN-Fiberglass 19mm-4lb | | Number of Items | 1 | | Package Dimensions | 31.5 x 26.8 x 7.8 cm; 1.86 kg | | Part Number | JIN-Fiberglass 19mm-4lb | ## Product Details - **Brand:** UPTTHOW - **Colour:** White - **Item diameter:** 0.75 Inches - **Material:** Fiberglass - **Shape:** Honeycomb ## Images ![Fiberglass for Cement Mortar Concrete Reinforcement Anti-seepage and Anti-cracking Cement Mix for Building Walls Garden Floor 3/4"(19MM)-1lb/PACK - Image 1](https://m.media-amazon.com/images/I/715nRghGIDL.jpg) ## Available Options This product comes in different **Size, Item Package Quantity** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by S***V on 18 October 2025* Perfect for adding to Bondo for extra strength.
