Oil on board. Gamblin oil ground. I realised too late that the second layer of ground was probably too thick and oil settled on the surface. This gave me adhesion problems due to lack of tooth. I lightly sanded the areas I hadn't painted and it solved it. But in other areas this textured pattern had already happened.
This is just very initial underpainting - a sketch really because my subject has so many architectural details I needed good placement with. I used liquin to thin the paint and help it dry more quickly - bad move really, I now realise. It resulted in this texture. It's not cracked, it's just raised in tiny ripples. I didn't think anything of it when I first saw it as I assumed i could just paint over it. George O'Hanlon on another site called it alligatoring and said the only solution was to remove the offending layer of paint. I've asked for clarification and haven't heard back yet.
There are many, many hours invested in this large work already, including blocked in faces of my four children. This appears in maybe 10% or so of the work - on the sides which I intend to darken as the work has chiaroscuro.
1. Is this considered a big flaw in art if this kind of texture is seen anywhere on the canvas? Like - art shows and artists would write off this work? Obviously it wouldn't look as obvious as this.
2. Have you experienced this before and found solutions? Other than remove the paint?
3. Is it possible to paint over it without the texture coming through?
4. Is it ok to lightly sand it (eg1200 grit) with sanding block to remove tops of tiny ridges? Of course, they will show up as different colour and might need opaque paint to rebuild again.
5. If I have to remove it, what is the best way? Some other areas had multiple layers of glazes - with liquin.
I'm discouraged I have to say.
