hardboard backing for canvas

[thecreative]

Hi again,

another quickie, after going around the houses with my artwork I find myself back with a smaller size - I'm using 400 x 500 hardboard, 370mm inkjet canvas, 3m fabric spray mounting to the hardboard - pva sealing the edges of the print, then taping up the edges & sealing again - this gives me a harder surface to paint on & also its hopefully not going to move - these are pre-sized so I can just drop a 300 x 400 mount over the top.

Its best process for smaller stuff as Im a artist not a framer, any helpful advice? What size would using a hardboard backing and mount work up to for rigidity etc..

Thanks in advance

The topic of using just about any spray adhesive has been a topic of conservation since the beginning of web based forums. Before that, it was a topic at conferences.

Consumer grade spray adhesives have a very short lifespan and are not recommended and have a tendency to "give way" over time causing very unpleasant visual as well as mechanical consequences.
A roll on adhesive (Dextrin -PVA - EVA based) will last longer as well as be less expensive in the long run per square metre. Also there will not be that toxic overspray. This method should be allowed to dry under weight such as a sheet of thick glass.

I'm using the spray adhesive as its far less messy and the edges are held with the pva and then tape as a failsafe to stop it ever moving, I was using pva & mounting to 6 mdf for open frames but switched to ACM - now I'm using a mount the prints are only 330 x 400 so its far quicker and less messy but I suppose its an option to go back to if its cheaper.

Costs have rocketed & I want my artwork to be reasonably priced so any cost cutting I can do is a bonus.

any recommendation which Eva & where to purchase?

Ask your local, UK based, suppliers

I've used Unibond in the past with success. It's basically wood glue diluted a bit. The key thing is to get even pressure
on until the glue has set - 24 hrs is my preference. Put the board/canvas between two heavy boards (19mm Chipboard?)
with sheets of plastic to stop any oozes sticking to the heavy boards. Pile lots of weight on top.

As for spray contact glues, as Jerome said, forget them.
They are intended for temp paste-ups and have no place in the art/framing world.

Evacon Eva from CXD international, or Lions if you have an account.

Any reason not to just paint on board ? Then you can just frame the board.
I paint on marine ply ( few layers of gesso first obviously) I find it a better surface than canvas but each up their own

Thanks

the board takes a digital canvas print of my base artwork which is then worked over in acrylic, its a mixed media technique
