Surface preparation made simple with Mr.Hobby B611

The Mr.Hobby B611 Aqueous Surfacer 1000 is a water-based spray primer aimed at RC model hobbyists who want a smooth, even base coat. Its fine formulation improves adhesion and coverage to help produce consistent paint results for both newcomers and seasoned builders.

Benefits of choosing a water-based surfacer

Water-based surfacers such as Mr.Hobby B611 reduce fumes compared to solvent primers and are easier to use in a small indoor workshop. They dry quickly and allow for simple cleanup with water, which makes multiple thin coats easier to manage.

Practical spraying tips for a clean finish

Start with a clean, dust-free model and shake the can well before use. Spray from roughly 15-20 cm away in light, overlapping passes and let each thin layer dry fully before adding the next. This technique lowers the chance of runs and produces an even surface for topcoats.

Compatible with common model materials

The Mr.Hobby B611 Aqueous Surfacer 1000 suits a wide variety of RC projects including cars, aircraft and boats. It bonds well to plastics, metal and resin substrates, making it a reliable primer for mixed-material builds.
