Mipa 4+1 Acrylic Filler HS dark grey (approx. RAL 7011 Iron grey)

Mipa 4+1 Acrylic Filler HS in dark grey, approximately RAL 7011 Iron grey, is a high-build 2K sanding filler for repair and refinishing work where the surface needs body, levelling and a clean sanding stage before the topcoat is applied. The dark grey shade makes it useful for colour-oriented preparation, especially where a deeper underlayer supports the following finish system better than white or light grey would. The filler remains firmly paintshop-focused, but its purpose is easy to understand in practical refinishing because it solves a very concrete problem: it helps turn repaired or uneven areas into a controlled paint-ready base. This gives the next coating layer a cleaner base and keeps preparation work predictable.

High filling power matters because it helps Mipa 4+1 Acrylic Filler HS dark grey (approx. RAL 7011 Iron grey) build the surface efficiently, but the sanding quality is just as important. A filler that is difficult to sand can slow down the whole process and leave the operator fighting Mipa 4+1 Acrylic Filler HS dark grey (approx. RAL 7011 Iron grey) instead of shaping the panel. This one is designed for the opposite result. It is intended as a sanding filler that supports clean preparation, reliable shaping and good control on spot repairs and larger refinishing sections alike. That is what makes it useful, not a long list of technical buzzwords.

The dark grey filler is especially relevant where a medium-to-dark foundation is preferred below the finish coat. That makes it a practical shade option in the available selection rather than just a colour variation for its own sake. The technical setup uses Mipa H 5 or H 10 hardeners together with Mipa 2K Thinner, but the core buying message stays simple: this is a high-build sanding filler that helps create a smoother, more even and more colour-appropriate base before topcoating.

How is it used? Mipa 4+1 Acrylic Filler HS dark grey is used after substrate preparation and before topcoating as a sanding filler that builds and levels the surface. It is suited to repair areas, spot refinishing and general panel preparation where a dark grey underlayer is preferred beneath the finish system. In everyday bodyshop work, it belongs wherever a filler should combine useful build, clean sanding and a darker foundation ahead of the final paint stages.
