Now use a grout bag to carefully fill in the joints with Veneer Stone Mortar. Make sure you grout the gaps and not the stones’ surface.
Want some color in that mortar? Before grouting, add Quikrete Liquid Cement Color to the gray veneer stone mortar and you’ll get a decorative accent to match or contrast the color of the stone!
Once the grouted joints are thumbprint hard, use a joining tool to remove excess mortar and smooth those joints for a clean, professional-looking result.
