This guide explains the differences between each variant, how to thin them using compatible Mr Hobby thinners, and application techniques for best results.
Understanding Mr Surfacer Types
- Mr Aqueous Surfacer: Water-based formula—low odour and great for brushwork or indoor use.

- Mr Finishing Surfacer: Ultra-fine for polishing and pre-gloss surface prep.
How to Thin Mr Surfacer
For Solvent-Based Mr Surfacer:
Use any of the following Mr Color Thinners depending on your volume needs:
- Mr Color Thinner 50ml (T-101)
- Mr Color Thinner 110ml (T-102)
- Mr Color Thinner 250ml (T-103)
- Mr Color Thinner 400ml (T-104)
- For a smoother finish: use Mr Leveling Thinner (T-106 or T-108)
Recommended Ratio: 1:1 for airbrushing, or slightly thicker for brush use. Adjust as needed for climate and surface.
For Aqueous Mr Surfacer:
Use only Aqueous-compatible thinners for proper results:
- Mr Aqueous Hobby Colour Thinner 110ml (T-110)
- Mr Aqueous Hobby Colour Thinner 400ml (T-111)
Recommended Ratio: Approx. 2 parts surfacer to 1 part thinner for brush use, or 1:1 for airbrushing. Stir thoroughly.
Application Tips
- Brush: Use slightly thinned surfacer to fill seams or fine imperfections. Multiple thin layers are better than one thick coat.
- Airbrush: Spray at 15–20 PSI. Allow 15–30 minutes between coats. Use smooth, even passes.
- Sanding: Use after full cure (about 30 minutes to 1 hour). Wet or dry sand with 800–2000 grit sponges, depending on the formula.
Which Surfacer to Choose?
- 500: Thickest—ideal for seam filling or surface levelling.
- 1000: General-purpose primer with balanced coverage and smoothness.
- 1200: Slightly finer—great before gloss or metallic paints.
- 1500 Finishing: Ultra-fine—perfect for high-polish finishes or final primer layers.
