MAX HB Filler
Acrylic primer 2K HS 4:1
MAX HB Filler 4:1 is a 2K acrylic filling primer designed for fast and cost-effective
preparation of parts prior to painting. Its HB (High Build) formula effectively levels minor
surface imperfections, sanding scratches, and marks left after surface preparation,
creating a stable and even layer for subsequent coating systems. The product features
easy application and soft, predictable sanding properties after drying, ensuring consistent
results and saving time in the workshop. It is easy to process, and with sufficiently long
flash-off times, multiple coats can be applied.
