Mipa 4+1 Acrylic Filler HS in light grey is a high-build 2K HS sanding filler developed to create a smooth, stable base before topcoating. Mipa 4+1 Acrylic Filler HS Light grey is designed for refinishing work where filling power and sanding quality are both important, and that combination is exactly why this filler is widely used in practical bodyshop preparation. It helps level the surface, supports clean transitions after repair work and leaves behind a more controlled base for the finish system.
A filler like this earns its value in the sanding stage. It is applied to build and refine the surface, then worked back into shape so the following coats have a more even substrate. Strong filling power is useful on its own, but the easier a filler sands, the more useful it becomes in real paintshop conditions. That is where Mipa 4+1 Acrylic Filler HS has its reputation. It is built for efficient sanding without turning the preparation stage into unnecessary labour, and it is also suitable for spot repair work without sinkage or visible edge marking.
The light grey shade, approximately RAL 7035 Light grey, makes it a practical base tone for many paint systems, especially where the later colour coat benefits from a controlled neutral underlayer. The filler is used with Mipa H 5 or H 10 hardeners and Mipa 2K Thinner, but those compatibility details stay in the technical section. The practical benefit is clear: this high-build sanding filler helps shape and stabilise the surface before paint, while staying straightforward to process in routine refinishing work.
How is it used? Mipa 4+1 Acrylic Filler HS light grey is used as a sanding filler after substrate preparation and before topcoating. It is well suited to repair areas, panel preparation and spot work where the surface needs building, levelling and clean sanding before the finish system is applied. In practical terms, it belongs wherever a high-build filler should leave a smooth, even and workable base that supports a more precise final paint result.
