Help repair Mioplosus.

Recommended Posts

Can someone recommend a repair for this specimen? It's a 16" Mioplosus I picked up early eighties in Ulrichs Gallery basement.  I prepped it and attached it to a 3/4" plywood base but it cracked a few years back.  The crack in the bottom left side isn't bad in the pic but it doesn't look great live.  I have been trying to match up putty but can't seem to get it right.  Any suggestions?

 

Thanks.

You can file off some matrix from the sides, and add that to your putty/glue/epoxy to match the matrix.

I never got the perfect color at the end..., what kind of glue do you use to mix?

My results had been, that the crack gets another color.. :heartylaugh:

 

in my next life I try to become an artists, this is one of the things I never learned and what I am really not talented in...

I have no personal experience with this, just what I have seen mentioned here.  :shrug:

This does not work with cyanoacrylate as it will be darker than the matrix even if you use powdered matrix.  I have done  it with White River specimens  and just made a water/powdered matrix putty to use on top of the actual glue.  It is cosmetic, not strengthening.

did you try a mix of dental plaster with matrixpowder? I tried with some White River specimens and some green river-slabs. I could work, it gets a nice color. But I am not able to reach the right one, I am really not talented as an artist....

You can also use matrix powder in Apoxie Sculpt. It will provide the dual benefit of some additional structural integrity. Mix up the epoxy clay and then mix in as much powdered matrix as you can, like you're making bread. Then, use a dental pick to jam it as far into the crack as you can. Once you get it level with the surface of the slab, you can use a damp sponge to texture it.

wow, that a good idea. Is there a maximum volume ratio from apoxie to powder? I never tried, used Apoxie sculpt only without powder
