Grout the Stone Joints

What happens here

Load a grout bag (similar to a pastry bag) with the prepared mortar mix. Using the bag, carefully squeeze the mortar into all the gaps and joints between the stones. Ensure the joints are completely filled, working from the bottom up to prevent gaps. The goal is to create a solid and consistent mortar bed between all stones. The presenter notes that with proper stone fitting, the grout lines can be made as thin or thick as desired.

Goal: Fill all gaps between stones with mortar for structural integrity and aesthetic consistency.
