# Best Decal Setting Solutions: Softeners That Snuggle Decals Into Detail Source: https://modelbuildlab.com/best/best-decal-setting-solutions Updated: 2026-10-20 Publisher: Model Build Lab. Our score is an editorial rating out of 10 (fit 35%, features 25%, build 20%, value 20%), not a customer rating. Method: https://modelbuildlab.com/how-we-research#our-score Decals straight from the water look like what they are: flat stickers sitting on top of a model. Setting solutions fix that in two steps. A setting fluid goes under the decal to improve adhesion and allow positioning, then a softener goes on top, temporarily melting the carrier film so it drapes into panel lines and around rivets. Once dry, the decal looks painted on. The critical variable is strength: mild solutions barely move thick decals, while aggressive ones can wrinkle or dissolve delicate printing in seconds. Different decal brands demand different chemistry, and technique - flooding, blotting, and above all not touching - decides the result. This guide compares the popular setting and softening fluids and matches solution strength to decal type. ## Picks ### 1.

Vallejo 73213 Decal Fix (18ml) Our score: 7.3/10 (Fit for the job 8/10 · Features and specs 6/10 · Build and materials 7/10 · Value 8/10) Vallejo Decal Fix in an 18ml bottle, an acrylic resin decal setting liquid brushed on over decals to help them settle and hold, suited to builders who want a non-flammable option. Pros: - Listing says it is applied with a soft brush and that several layers can be built up, which gives control on stubborn decals. - Acrylic resin formula that the listing describes as neither flammable nor toxic, a plus for a home workbench. - The listing states a final varnish will not disturb the decal, so it fits a normal decal then clear coat workflow. Cons: - The listing gives a 17 to 18ml bottle size and little else, so it is a small amount for a big decal sheet project. - It is a fixing liquid only; the listing does not describe a softening action like Micro Sol, so tough curved decals may need a second product.
