APL20 SM
White acrylic enamel (30 gloss)
Two-pack white acrylic enamel (cured with AC40). Tough, flows out well in thin coats, flexible, good chemical and physical resistance, high hiding power, non-yellowing, and shows the grain/pores nicely. Used as a top coat on its own or as the base colour in patina finishes.

always — 2K system
Catalog gives 10–20 % (no by-volume figure); dealer t-colormarket and the official page give 10–20 % w/w / 15–25 % v/v. Tip: run towards 20 % for kitchen/bath resistance, towards 10 % for more flex (not a manufacturer statement).

S50 universal/normal; S80 slow, for >25 °C or large flat panels
S50 is the default and suits verticals; S80 is slow: above ~25 °C, large panels, better flow on flats, but more dust pick-up and sag risk. Neither changes cure time.
open-pored timber (oak, ash) — better colour and pore definition; apply 200–250 g/m²

Air spray is the official method (catalog card and product page: 'spray'). Transfer efficiency up to 40 % (methods page).

Not ideal for a finish coat — rougher atomisation; prefer airmix.

Can be combined with any spray method (methods page) — chairs, legs; check the mix conductivity first.

- Don'ts
- don't eyeball AC40 — weigh it
- don't use mix past 6 h pot life
- don't brush — spray only per manufacturer
- not for exterior — interior enamel
- don't sand/polish the final 20/30-gloss coat — it goes patchy

Safety: Flammable solvent-borne coating; AC40 hardener is an aliphatic polyisocyanate (catalog p.19; dealer). Spray in a booth with extraction, wear an A2P3 respirator (or air-fed), nitrile gloves and eye protection. No naked flames. Isocyanate hardener is moisture-sensitive — keep the tin tightly closed.
