Vallejo - Surface Primer Color | Black Acrylic Primer 200 ml (6.76 fl.oz.) | Matte Finish and Fast Drying | Perfect for Airbrushing and Great Adhesion to Figurines and Scale Models

This stuff really is great. It sprays smoothly and gives solid coverage with excellent adhesion to 3D prints and miniatures. The quality is obvious from the first use. The finish is listed as matte but I would describe it as a very subtle satin instead. It dries to the touch quickly but giving it about 24 hours to fully cure makes a big difference. Once cured it becomes rock hard and extremely durable. I ended up returning it only because I wanted a completely matte finish but it might work out perfectly for you. Ps. In the picture of the left is with the primer and the right is without. I 3D printed this part with PETG filament.

Vallejo Black Mecha Primer is hands down the best black primer I have used. It is nice and thin, goes on smoothly they an airbrush and can be mixed with thinner for a great consistent application. It’s thin enough to where you can even brush it in and not lose definition in a model. It is a great Vallejo black and will give you great shadows w out having to use a black paint if needed. Best primer ever

Flows well and goes on smooth. Easy to apply with brush. Color is very dark and covers well

Worked so well! I used this as a brush on primer for my warhammer mini's and it just looks fantastic! Great product!

Best primer....period. Smooth, colorfast, even, easy to work with.

This primer works fantastic in the drybrush right out of the bottle, it very easily sprays on a nice coat that's not too thick or thin and dries fast (but not too fast). The primer seems to have a decent amount of "tooth" to it and paint sticks to it pretty good. It forms an extremely durable layer that is very difficult to stretch or tear once fully cured. My only issue is that I repeatedly noticed that after I had primed a piece and let it dry to the touch, I would set it down to cure and then the next morning I would find a few places here and there where the primer had flaked off. I'm always careful to make sure that the pieces are clean and dry before priming so I'm not too sure what the issue could be. Regardless, it's easily touched up again.

I received an airbrush kit for Xmas. Vallejo primers work great with it. After tweaking the psi, and trial and error, I was able to prime a dozen miniatures with ease in 30 minutes. Although the bottle states it’s airbrush ready, I did find that cutting the primer 50/50 with Vallejo airbrush thinner works much better than straight primer alone. No tip dry with the 50/50 mix, whereas I had to clean the needle repeatedly with the straight primer. It’s a good idea to grab thinner if you’re going to use this with an airbrush. Even though it’s designed for airbrushes, the primer can also be brushed on if you don’t have one. Either way it beats using rattle cans to prime and varnish. I will be buying the white and grey primers, and a matte varnish from Vallejo as well.

I used regular vallejo black paint to prime for years before trying actual primer and the difference is night and day. Goes on a bit rough looking but dont get discouraged. Once it dries it looks absolutely flawless. Allow it to cure until the sweet chemical smell has gassed off fully (around 12-20 hours) for very best result.
