Install First Row of Tiles

What happens here

Begin by 'scorching' the back of each tile with a thin layer of thinset mortar to ensure better adhesion (back-buttering). Apply a layer of thinset mortar to the uncoupling membrane using a 1/2 inch notched trowel, ensuring the grooves run in one direction. Place the first tile onto the thinset. Use a framing square to ensure the first tile is perfectly square and serves as a straight reference point. Insert the base of the leveling clips along the edges of the tile, making sure they are flush against the previously laid tile (if applicable) and in alignment for consistent spacing. Press the tile firmly into the thinset.

Goal: Apply thinset to the membrane, back-butter the tiles, and set the first row, ensuring straightness with a framing square and using leveling clips.
