usagi juku ciment product

[kenran]

Hi,

I would like to create an armor using cardboard and joint ciment before making a real one ( metal ) like usagijuku does.
Anybody know which product do they use ? they said "joint cement ( YOSINO plaster Co.,Ltd. wall crack repair agent" but i don't know if it's for ciment(concrete) or plaster. I used plaster mortar to paste placo(plaster) panels but i still have cracks after 3 layers and the armor parts are flexible.

Thanks for your help

ok i found out it's an universal filler for both plaster and concrete like :


I'm making a 16 plates kabuto, i'll post the result on friday with the filler.

Filler dry faster than i tough. So here the pictures.
Pattern from nihon katchu's 16 plate kabuto ( cardboard from beer pack )


Not sanded yet, looks a little ugly but now not flexible anymore and no cracks

The "PVA" on the label there might be for "Polyvinyl Acetate", an ingredient commonly found in what we call "white glue" or "Elmer's Glue" in the USA.

I also tried this one from a friend and the result have the same quality.
