Epoxy for aquarium Background

To preserve the nice colors on my aquarium background by RockZolid I will have to protect it by applying epoxy resin. To test the epoxy resin I first put the resin on some modules first:

First I collected all I needed. Resin and hardener from Mr.Boat. With the resin I ordered some paint brushes, gloves, measuring cups and stir bars. All was nicely packed and delivered, ready for use.

I loosened the caps for the resin and hardener, I didn’t want to get stuck half way and not being open the second bottle.

Mix them real goed. The resin and hardener have to be mixed very, very well. If you don’t mix them well enough some parts of the resin will stay soft.

To prevent the epoxy sticking to my hand, which can irritate the skin, I used gloves. Looking at the amount of epoxy on the gloves after I finished, I was glad I used them!

Epoxy is just like liquid glue, you can apply it easily with a paint brush.

The paintbrush is very flexible so I can apply the resin to all the cracks and crevices.

After applying the resin it just takes time to harden.

I have applied the epoxy to the modules the day before yesterday. By the looks of it, it has cured real well. Unfortunately I missed a few spots but nothing I cant fix later on. The modules are very shiny, underwater this will disappear. After applying the resin I have patted the resin with a towel but despite being really sticky it just flowed back in place and is real smooth again.

Before you begin a small tip…..epoxy flows down and sticks to newspapers. One part of a module stood on wooden spatula: It was glued solid to my module and was really hard to remove. Make sure you put the modules or background somewhere it doesn’t get stuck. Just use newspapers to catch falling droplets.
