I think the cost per sf thing is somewhat meaningless and I would steer the customer away from thinking in those terms. Think instead about how many days and how many techs it will take to get it done. Add the cost of the sealer. Again you have to test to see whether one application will do it (probably not for terra cotta). Aldon has coverage guidelines on their labels. For instance, Mexiglaze is 75sf -400ft. per gallon. The other issue is that it is not returnable. So testing is a must. But, for example, if you have 1000 sf and the stuff costs $70/gal and you need 10 gallons, it will run an additional $700. Seems expensive, but we are doing 1600 sf of Bluestone and hexagonal pavers this week with Aldon paver sealer and the cost is over $800 for just the sealer.

Hi Anthony. We have restored quite a lot of Mexican tile in our day. The main issue isn't the sealer, it is what it will take to get any old sealer off and repair the grout if necessary. I always underestimate how long it takes to get tough sealants off. But sometimes it isn't so hard. I would highly recommend that you do a test. I would never not do a test. I have learned my lesson. 
As for sealants, I am a devotee of Aldon products -SBS sealer, Porous Stone sealer and Mexiglaze . These 3 products are more or less the same concoction with progressively more solids, so you can mix them and cut them with lacquer thinner. Go to Aldon Chemicals website and check them out.  Aldon Products stink like crazy but probably not an issue outdoors.  Stone glamour is another similar product but I haven't used it. I have used Drytreat Intensifia indoors and the stuff is great and doesn't have as strong an odor, but it is really expensive.
