been thinking about this type of scape since i saw people using greatstuff and eggcrate. my one unknown fear was the silicone not adhering to the rock once completely saturated. have you experienced this or is there enough "bite" because of the rocks porousness? i love this look and proof of concept. thanks in advance for any help or advice
Using silicone wasn’t an issue at all. The STAX Rocks have lots of holes and are porous. Everything that is siliconed is still holding strong .
