Karen McDonald –
I used the brown foam to fill gaps in my terrarium and it expanded perfectly. It blends well with the natural look and holds its shape after curing. Great for small-scale landscaping projects.

The grey foam worked well for my aquascape. It expanded evenly and didn’t bubble or leave residue. I appreciate the natural finish it provides without needing extra materials.
