I am in the process of designing a 16,000 gallons Koi pond. The pond will be six feet deep and one side wall will be completely above ground. I intend on building a block wall with Xypex admix in the mortar and concrete fill and then having the interior shot with gunite.
My question is can Xypex Admix be directly mixed with gunite as it is shot or is it better to surface coat the gunite? Or both?
