HPS20
HPS20 White water-based primer
General-purpose white one-pack water-based furniture primer. Wets out and flows well, builds good hardness with minimal shrink-back. Dries fast and sands well. No organic solvents — it dries purely by water evaporation.
- furniture fronts and panels
- doors
- MDF and HDF furniture parts
- veneer and solid wood of various species
- white base under the HPL20 SM water-based enamel

Usually 0–5 %: at 20 s VZ-4 it's already close to spray viscosity. Only add water if the gun won't atomise it cleanly, or on hot days.
Clean water only (demineralised is best), never S50/S80 or other solvents. No hardener: this is a one-pack product.

- don't store or ship below +5 °C
- don't sand before 4 h, or it clogs the paper
- don't lay it on heavy on verticals: it isn't thixotropic
