Optimal Thinset Coverage and Ridge Collapse with 1/2" x 1/2" Trowel

What happens here

For optimal results, the presenter recommends using an even larger trowel, specifically a 1/2 inch by 1/2 inch notched trowel. He applies a generous bed of thinset with this trowel, places a tile onto the thinset bed with leveling clips, and presses down firmly. Upon removal, the tile exhibits excellent ridge collapse and nearly 100% thinset coverage on its back, indicating a strong, durable bond. He summarizes the comparison between all three trowel sizes, noting that even though a 1/2" x 1/2" trowel seems significantly larger, it only adds about 1/16 to 1/4 inch more thinset than the smallest trowel, yet provides vastly superior coverage and bonding. The demonstration pieces are then spectacularly destroyed with a large wrench.

Goal: Achieve optimal thinset coverage and ridge collapse for maximum tile adhesion.
