Mix a Small Dab of Quick-Set Mud Right on the Knife

The Problem

Quick-set joint compound is the right material for filling dings before paint — it cures in minutes instead of drying overnight. It's also intimidating in exactly one way: mix a pan of it, fuss over the consistency a beat too long, and the whole batch sets up before it touches the wall. For a handful of nail holes, a pan is a waste and a race.

The Technique

Skip the pan and mix on your knives:

1. Set out a bucket of clean water and your bag or bucket of dry quick-set (20-minute works well), plus two knives — one small, one wide. A trowel makes a good wide one.
2. Dip the small knife in the water, then into the dry powder, then water, then powder — alternating, each dip stacking a layer — until the knife carries about the amount of mud the job needs.
3. Finish with one more dip in the water.
4. Scrape the loaded knife off onto the wide knife, and mix it right there on the blade until the dry clumps are gone.
5. You're holding a small, perfectly workable blob — fill your nicks and dings straight off the knife.

Nothing to wash but two knives, nothing wasted, and the clock never gets a vote.
