Apply First Coat of Venetian Plaster

What happens here

The presenter begins applying the first layer of Venetian plaster, specifically in the color Gauntlet Gray, to the large main tiles of the fireplace. He uses a flex trowel for this application, spreading the plaster across the tile surface. A key instruction emphasized is to *not* push the plaster deeply into the existing grout lines. The goal is to cover the tiles while preserving the integrity and definition of the grout lines, which will be subtly colored later.

Goal: The presenter applies the first coat of Gauntlet Gray Venetian plaster to the large fireplace tiles using a trowel, taking care not to fill the existing grout lines.
