What Customers Are Saying

The masonry bonding agent appears to be an effective product for improving the adhesion and strength of concrete, mortar, and other masonry materials. Many customers reported positive experiences using it to bond new concrete to existing surfaces, patch and repair concrete walls and floors, and improve the workability and troweling of mortar mixes. Key benefits include creating a strong bond, enhancing adhesion and workability, and strengthening concrete and mortar. However, some customers found the product to be a bit runny or difficult to mix, and felt it was relatively expensive compared to other options.
