Mounting canvas to a Board

Hi thecreative.
To answer your question, any sort of wet adhesive is going to be a bit messy.
I suggested plywood as it is less liable to warping even if not cradled as seen on the Ashcraft Framing web site.
The other advantage of using plywood is that it is compatible with using PVA glue. The acm is a composite board of plastic and aluminium, both of which are unsuitable for use with PVA glues.
PVA performs best if allowed to cure under pressure. A cheap vacuum storage bag will give you sufficient pressure to satisfy that.
Use a roller if you will but I wouldn't like to rely long term on the bond.
I would always glue the board to a slightly larger sheet of canvas and then either trim away the excess or fold it over the sides. Either way is OK as the edges are hidden under the rebate.
