Step 3: Pouring the Epoxy Resin
The epoxy resin I'm using has a 1:1 ratio1:1 ratio for solution A to B. I'd already decided that I wanted the color theme of the box
to be red against blue. In cases like these, I prefer mixing and pouring the resin in rst before adding the color. I
calculated a rough volume of the space that had to be occupied by the resin (in my case 8.5x5.5x0.5cm which is
23.375cm^3). I tend to round up so I chose 25cm^3. I split this fty-fty between solutions A and B measuring out
12.5cm^3 of each. I then mixed them together in one cup. What became extremely important here was making sure they
were very well mixed togethervery well mixed together. I used a wooden stick to do this.
Once the two solutions are joined there is a limited time before they started hardening which is why it's important to
work fast. Once I felt they were adequately mixed (30 seconds of mixing30 seconds of mixing) I poured it into one of the mold spaces. The
objective is to ll it up to the brim and if the measurements were carried out correctly it should. I rounded up earlier
because some resin always tends to be lost when transferring between containers (stuck to sides).
When the resin was in I began adding my color pigments ( blue and whiteblue and white) and moved them around until I got a
satisfactory result. I then waited to let it dry. Once this was done I repeated the same process for the other mold and used
red and whitered and white this time.
Once both were done and dried. I sanded sanded down the surface till the wood and resin were exactly level. I then gradually
increased gritincreased grit to get rid of any noticeable scratches on the resin as those tend to stick out. It's very common to sand
epoxy resin with wet sand paper (sand paper where the grit still sticks when it's wet) as well as it can bring out better
