Cement render (and lime mortar etc.) will not adhere for any length of time to tufo. Tufo is porous and absorbs water when breached. If you want to seal from the outside, the product you require is "fissativio". €5-6 for a litre which will cover around 12 m2. However, unless you have perfect adhesion, all you will be doing is sealing the water in. Unfortunately, I don't think that there is too much that you can do. If its any help, we have the same problem.
