What happens here

The consistency of mortar is crucial for successful block laying. If the mortar is too wet, it will push out from the joints when a block is placed, leading to messy work and weak bonds. If it's too dry, the block won't properly settle into the mortar bed and achieve full contact, resulting in a poor bond. The ideal consistency is stiff enough to hold the block's weight but still allows for slight adjustment when tapped with a trowel or hammer. This ensures maximum contact and bond strength.

Goal: Mix mortar to the optimal consistency for strong, stable block installation.
