Good video. I’ve started preparing acrylic gesso panels as a new surface for my work. Previously, I used oil-primed surfaces because I prefer a completely non-absorbent base, though, as you mention, oil-primed surfaces require around five days to cure. To reduce the absorbency of the acrylic gesso, I apply a final layer of damar retouch varnish, which seals the gesso well but still leaves a slight absorbency and tooth. One tip I’d recommend is to coat the sides and back of the boards with gesso, especially if you paint en plein air. These boards are prone to water damage, as you noted, particularly in high humidity. Over time, the fibres in the boards can swell and start to deteriorate.
Merci Marc !

@@AlexKellyArtUK hey thank you, that’s a great tip 🙏🏻
Is there a need to seal the rear?
@@PatrickFitzgerald-i9v no. Unless you think the panel will be in extremely high humidity or wet. Other than that, no need to seal the rear 🙏🏻
