Our multi-purpose floor joint repair adhesive is carefully formulated with sodium lignosulfonate， dibutyl ester and sodium chloride. Designed specifically to provide excellent adhesion and firmly connect to various floor materials. The usage method is extremely convenient: Ensure that the construction joints are free of dust and loose， and keep them dry. Open the bottle cap and install the pointed nozzle (which needs to be prepared by yourself). According to the width of the gap， make diagonal cuts to the nozzle to adjust the outlet of the glue. Pour the glue evenly along the gap and let it cure naturally after filling the gap. And it can be applied to various floor surfaces， such as concrete， tiles and wood.
