Dymax Composeal Bonding Sponge is a non-toxic bonding sponge for aquascaping. It is used together with scaping glue, and the pair give a quick, durable and waterproof bond on the wood and rock that aquascapes, terrariums and paludariums are built from.

The usual way of doing this is tissue paper and glue, which then needs hiding. The bonding sponge comes in natural colours that blend into the scaping material, so there is no cosmetic touch-up afterwards.

How the maker says to use it

1. Hold the two pieces of scaping material firmly together.
2. Pack the bonding sponge densely into the join between them.
3. Apply scaping glue evenly over its surface, covering the far side of the join as well.
4. Give it a few seconds to cure.

Choosing a colour

Two colours are stocked, both 50 g. They are the same bonding sponge - pick the one that disappears into your hardscape. Each has its own barcode, in the table below.
