I don't have the first hand experience on this, but my guess
is that, acrylic media by itself is too hydrophobic, and does
not absorb moisture any bit, once dried. I don't think
dilution is a key factor, unless you dilute to an extent where
there is no effect of applying the media. I would rather
suggest to use a mixture containing other polymers, such as
gelatin, hydroxymethylcellulose, polyacrylamide and/or
polyvinyl pyrrolidone, wherein acrylic media is used in less
than 20%, perhaps much less. But if you have to do all the
research, you might want to buy existing products...

Common matting agents include tiny beads of poly(methyl
methacrylate), poly(methyl methacrylate-co-methacrylic acid),
and silicon dioxide. The first two are commonly used in clear
acrylic medium that give matte finish. There are more options
if you want opaque matting agents. These are blended into the
binder before coating for matt surface.
