Fastset Mortar Mix - How many layers to apply?

[onedge30]

Acrylic polyurethane, I would think. Check to make sure it is non-toxic.

Now this is for a vivarium, but will not have any water against it 24/7?

Well it will have a water feature. It will contain a waterfall where the water flows down the rock face into a stream.

I did find this product for sealing concrete counter tops which is non toxic and food safe.

Jeff,

Ask and you shall receive! Here are two images of the rock wall in progress. Three layers of Fast Set Mortar mixed with Acrylic Binder have been applied to the hard pink construction foam. I have painted the rockwork with patio acrylic paints in a wash fashion. All the pink foam has been covered with a coating of black silicone for a more pleasing effect as well as to keep the water from hopefully seeping in or scratching the vivarium glass sides. I will apply a bead of new silicone to the glass and front edge of the rock wall to seal it inside the vivarium. Before the silicone dries I will push in some shredded coconut fiber to give it a more pleasing look. Where you see the green color is the location of the water flow area down the rock face and is intended to represent some algae or moss growing. At the bottom of the rock feature is a pcv drainage pipe that runs through the foam to the back chamber where the adjustable flow pond pump, 50 to 80 GPM will be. I also plan on putting a filter back there to help keep the water clean.

New to frogging, but you probably don't want to use a kitchen/bath sillycone cuz it has antifungal chems in it. At least you shouldn't use it in reef aquaria. Might not be as big a deal here but the regular window/door stuff doesn't have it. FYI, FWIW :-) looks awesome, BTW..
