Q: has anyone else had an issue with GW sprays, specifically paint not really adhering to them overly well?

I know they are note specifically marketed as primer, though to date I've not had any issues with the spray itself coming off - however I have found that other paints (including GW own base & layer paints) while brushing on nicely once dry can be seriously easily rubbed off - even by gentle contact and even several days later. e.g. Khorne Red, washed and highlighted over Wraithbone spray where a lot of small flecks of bone show through where the model has touched against a desk.

not had this with other sprays, or airbrushed primers (sadly airbrush out of commission currently).

doesn't seem to be every single colour that suffers from it but reds & golds seem to be bad for it.

can seal with varnish once the model is done but have noted a whole range of small, but irritating, defects cropping in with paint rubbing off.

I've not had that issue personally, but GW isn't my go-to.

Only thing that comes to mind: Is the primer fully cured before painting over it? I leave my models overnight at least before painting on top of any primer. It can appear touch-dry long before it is fully cured, and any non-water solvents left unevaported underneath a water-based top layer can cause chipping or peeling.

should be dry, left a few days at room temperature - usual is at least overnight after a few hours to flash off as well.

not had this with any other spray (have had a few of the old ones plastic soldier did go hydroscopic and had to basically scrub a wash on) but never had any like this.

it is weird as its only a few colours over that seem to do it, would put it down to bad luck but had it with the wraithbone spray from a few cans and a grey seer can as well - to date the only two others from GW I've tried have been fine. and even then its only a few colours when others are fine on the same model

*spooky music*

I've had some trouble with paint beading up on top of Leadbelcher spray.

I've never had any issues with GW primer. In fact, I actually shell out more for their expensive primer because it works so well for me.

I have this problem with Stynylrez(or whatever the hell its called!) and Vallejo. With black primer the paints work well but the grey stuff can be pure hell. Brown spectrum seems to be the worst for not adhering to it. Can only think that the grey primer may be too smooth?

I have only had positive experiences with these latest batches (after the contrast one came.)

The gold one does not cover very well, I did 2 passed with it this summer. It covered very badly now this Christmas, but that was because I sprayed in winter I think.

I only use the spray to make the undercoat better to apply. Paint does kit stick well to plastic, but it sticks to the undercoat. 🙂

have used various sprays and oh so yes paint sticks to them, car body primer is decent (and cheap), the army painter ones have been a general go to recently (usually red, brown or grey), gave the GW ones a go, nice colours and they seem to work, not quite as cheap but meah its paint. do like the GW colours and how they apply.

was just curious is anyone else had the same issue, if not its presumably down to me

May be a quirk of the climate? Humidity and stuff can affect the paint even if its a dry day otherwise.

I haven't had any problem with any GW spray paints in years. They're my favourite sprays. Vallejo has a bigger range of colours, and Montana and Liquitex have massive ranges, but GW sprays just lay down nicer and I find it much easier to do zenithal highlights with them.

They both seem to stick well to the models, and paint seems to stick to it fine, so even though they're not called primers I think they fill the role of a primer acceptably.

So maybe you've had a bad batch or a usage issue, or maybe an issue with Khorne Red specifically, I've never used Khorne Red specifically.

I did have a forey into some off brand paints from a painting and hobby shop. They had some displayed on some tin cans that looked amazing. Applying it to my models it was very thick. Or more precise in order to get coverage I needed to get pooling as well. I had to apply them while the models where on the sprue. Not the worst, but definetivly a let down for me.

I haven’t had a problem with adhesion, but the ones they made for use with contrast paint need a lot of shaking and need to be put in some warm quarter otherwise they don’t spray well

I have had a leadbelcher spray that gave such a slick finish that the wash beaded a bit.

Same, the only one I've had an adhesion issue with is the leadbelcher spray, though it just took extra layers to overcome it.

Sounds like you didn't shake it enough.

If you did multiple thin coats the models should be ready to paint in an hour or so. If ypu need to dry it for a full day, then you way oversprayed.

OP, this is mostly an issue with Wraithbone and Grey seer sprays because they are engineered as bases for Contrast paints, which means that they have a satin finish. This gives a smoother surface which paint won't adhere to as strongly as it would on a matte surface, but enables Contrast paint to flow easier.

The only answer that I can think of is to spray a coat of varnish before handling.

not that it needs a day, its just that with other primers I've seen 24 hours to let it fully cure recommended and its quite easy to spray one day and paint the next so thats what I tend to do. its a thin coat, usually twice from different angles, an hour or two between to dry but not cure so it bonds to itself nicely

no problem with the primer sticking to the model, just some colours sticking to it, contrast rubs off when you looks at it but guess thats because its so thin

yes gets varnished at the end, just not had a problem with stuff rubbing off when actually painting it. have to say not noticed any satin finish as such, they seem as matt as any other colour, only the metals seem to have that effect
