Painting process
Tape, paint, pull the tape, then seal
The diagonal diamond grid was taped out across the room on the first visit, using template tiles to set the pattern scale, then refined and tightened on a second visit before any paint went down.
On the third visit, the alternating diamonds were painted in two coats. The tape came off the same day, while the paint was still fresh enough to pull clean lines instead of chipped edges.
Once the paint had fully cured, a two-coat epoxy-based polyurethane topcoat sealed the whole floor for a durable, glossy finish.
