Process notes

  1. Minimum 1 hour drying time between each coat.
  2. Before each dip, mist shell surface lightly with Remasol SP-30 spray bottle.
  3. All 12 coats use the same slurry — no prime/backup distinction.
  4. Coats 1–3: dip only, no stucco.   Coats 4–6: fine silica sand.   Coats 7–9: medium silica sand.   Coats 10–12: coarse silica sand.
  5. Apply stucco immediately after dipping while slurry is still wet.
  6. Allow full overnight dry after coat 12 before burnout.
