Off the top of my head, Royce, it seems like 2500 psi. is what I've read, but someone will surely correct or affirm.

I reckon there are a lot of determining factors to achieve that # , though.

The psi of deck depends on the amount of cement in the mix, how hard it was packed and if you used admix. I would say it can range from 1200psi to 3000psi.

"It has been suggested that deck mud should be mixed with latex additive instead of water, this to make the mortar more cohesive and to give it greater compressive strength. Well, I'm here to tell you that mortar made from sand, cement and water can easily attain a compressive strength of 3,000 psi or better. That strength is more than adequate for shower floors and other small areas. Adding latex in this instance is simply a waste of time and money."
