    Same grit-free basecoat, same 45-minute working window, in a 2.5kg bag for a smaller run of joints or a patch repair rather than a whole room.

    Mixes to a smooth paste, sets by chemical reaction so it won't shrink away from the join over time, and sands back clean once hardened, ready for a topcoat. If the job is bigger than a room's worth of joints, the 10kg bag works out better value.

    Full specs are in the tabs below.
