Dear Mitra community,
i want to ask do we really need to seal the wood for oil painting? i am using acrylic gesso ground and oil painting on top of engineered wood panel, called Masonite tempered hardboard.
from one online source, i heard people saying wood had to be sealed before applying any acrylic grounds, because acrylic product had water, if wood is not sealed, the water content will wrap the wood immediately. but the source not specify which product is best to seal the wood that bonds acrylic ground well.
and i also see people suggest to use gloss acrylic medium to seal/"size" wood panel before apply acrylic gesso. however i think all acrylic is porous, so not sure how gloss medium can really seal the wood? even it could, its water content will wrap the wood first?
in addition, i see Golden is now advising not to use gloss medium any more if for oil painting, they suggest to apply acrylic gesso directly in several coats. then the question will be if apply acrylic gesso directly, will it seal the wood? or its water content will keep wrap the panel in each layer?
finally the thought is do we really need to seal the wood and what is the best product to seal the wood? can acrylic gesso seals the wood and act as ground as Golden suggest is a good practice?
thank you.
