The man who is behind the revival of Acronal D 300--nearly an alias
for "Lascaux consolidation medium" (LCM)--, is Peter Tongeberg in
Sweden--ask him. I had a note about all this in Restauro Number 1,
2005, p.67 as report on the meeting at Lascaux where they presented
this "new" medium, then Lascaux published its own little report in
the same periodical, Number 3, 2005, p 175.

Managing matteness of this medium is mainly a question of thinning
down the solution. I haven't worked a lot with Lascaux's LCM and
never considered neither the original Acronal D 300 nor the Lascaux
version as particularly adapt for consolidation of really matte
paint. It has a slight tendency to be shiny.

Its content of PVC (Acronal has, but apparently not Lascaux LCM)
doesn't necessarily make it a good choice for your project. I had
much better results with Paraloid B 72 in Acetone at 1-2% solutions,
but I haven't seen your object and its problems.
