1mm plexiglass
we start by bulding molds for the resin
epoxy resin
hardener
in the middle we will put a piece of paper with a print
we will see more precisely to wath extent the resin is polished
to start with, we'll mat the resin
we will use 80 grit sandpaper for this
I think it's good
sandpaper 120
we have to be careful in which direction we grind
we are not doing it in the same direction
we grind in the opposite direction to the previous one
when we sand crosswise we can see if we can use the naxt sandpaper
we continue to sand with the sam paper
now we can see that paper 120 has removed the larger scratches of paper 80
360 sandpaper
it is fine sandpaper
we use water so that the dust does not stick together and does not clog the sandpaper
we can still see the previous scratches
we can add clean water
now is good
600 sandpaper
we can still see the previous scratches
more water
sandpaper 1000
we'll grind it out a little more
sandpaper 1500
sandpaper 2000
sandpaper 2500
abrasive paste
polishing paste
light scratches are still visible
therefore it is better to polish mechanically
unsanded resin for comparison
