Mix and Apply Grout

What happens here

Prepare the grout by mixing it with water in a clean bucket using a drill with a mixer attachment. The presenter advises mixing grout for at least 7 minutes, which is longer than thin-set, to ensure complete hydration. After the initial mix, let it slake for 5-10 minutes, then mix again for a minute or two. Once mixed, use a tile squeegee to apply the grout generously over the tiled surface, working it into all the gaps and crevices between the tiles. Scrape off excess grout from the tile surface as you go.

Goal: Fill the gaps between tiles with grout.
