Walthers Solvaset Decal Setting Solution 2oz Bottle

Walthers Solvaset Decal Setting Solution (2 oz) is a proven decal setting solution used by modelers to help waterslide decals settle down into rivets, seams, louvers, and panel lines—so markings look more like paint and less like a “sticker.” If you’re fighting silvering, trapped air, or decals that won’t conform to detail, Solvaset is a go-to decal setting solution for getting that clean, scale finish on freight cars, locomotives, passenger equipment, and scale model kits. 

Why modelers use Solvaset

• Helps decals conform to surface detail like rivets, grout lines, corrugations, and raised/etched lettering
• Reduces silvering by helping the decal film lay tight against the surface
• Improves the “painted-on” look for more realistic weathered and clear-coated finishes
• Great for model trains & scale models (HO, N, O, aircraft, armor, automotive, and more)

How to use

1. Prep the surface: For best results, apply decals over a smooth gloss or satin clear coat.
2. Place the decal: Position your waterslide decal normally and gently wick away excess water.
3. Apply Solvaset: Use a clean, soft brush to touch Solvaset onto the decal surface—let capillary action do the work.
4. Let it work: The decal may wrinkle while the solution softens the film. Do not touch it while it’s working.
5. Seal when dry: Once fully dry, protect your work with a clear coat, then weather as desired.

Pro tip: If you’re working with very thin decals or delicate inks, test on a spare decal first. For thick or stubborn decals, a second light application after the first dries can help the film pull down into deeper detail.

Frequently asked questions

Is Solvaset the same as Micro Set or Micro Sol?

They’re similar tools, but not identical. Many modelers consider Solvaset a stronger decal softener for getting decals to conform over deeper surface detail. Micro Set/Micro Sol are often used when you want a gentler approach. If you’re unsure, test first—especially on very thin decals.

Will this fix decal silvering?

It can help significantly, especially when decals are applied over a smooth surface and the solution is allowed to fully soften and pull the film tight. Proper surface prep and sealing are still important for best results.

Can I use it on matte paint?

You can, but it’s not ideal. Matte finishes trap microscopic air under the decal film, which increases the chance of silvering. For best results, apply decals on a gloss/satin clear coat, then seal and flatten afterward.

Do decals wrinkle after application?

Often, yes—wrinkling is normal while the solution works. Let it dry completely without touching the decal. The wrinkles typically settle out as the film tightens down.

What scales does this work for?

Any scale—HO, N, O, S, and more—because it’s about decal film behavior, not model size.
