How To Make a 3‑D Aquarium Background Using Foam‑iT!® 5

Step 7: Painting with Smooth‑Cast 327 and So‑Strong

Smooth-Cast 327 COLORMATCH Series urethane resin is used to create a plastic paint that is brushed on in thin layers to color the foam. It will be colored with SO-Strong pigments.

Dispense part A. Dispense an equal amount of part B. Add SO-Strong black to part B. Transfer part A into a larger mixing container. Add black pre-mixed part B to part A. Stir parts A and B together until there are no streaks. Mix together thoroughly for 3 minutes. Smooth-Cast 327 has a pot life of approximately 10 minutes.

Use a paint brush to paint resin onto the foam casting. Use a stippling motion to work resin into deep detail. Add multiple layers of pigmented resin to create color highlights.

Dispense part A. Dispense an equal amount of part B. Add SO-Strong purple to part B. Transfer part A into a larger mixing container. Add purple pre-mixed part B to part A. Stir parts A and B together until there are no streaks. Continue to paint using different colors to create highlights.

The foam rock wall is now completed. Remove the plastic backer from the foam rock wall before placing it in your aquarium.
