The procedure for cleaning up dog urine from limestone flooring is different and considerably more difficult to that used on carpet or wood surfaces. However, this isn't to say it isn't possible - providing you apply the correct poultice mixture to the affected area of the floor tile, you should be able to remove the stain and any resultant odor in its entirety.
Although you would normally use a deodorizing dog urine spray bought from a pet store to clean up urine stains, a stronger mixture of ammonia and talc chalk is more recommended for limestone rock flooring - especially as sedimentary rock like limestone has a tendency to absorb excess fluid. With this in mind, you need to mix together your ammonia and talc chalk in a hard-wearing plastic bowl until it reaches a gloopy paste consistency. If you think the mixture is too thick, add more ammonia. Likewise, if it appears too thin, add a touch more talc chalk.
Before you apply the poultice mixture to the urine stain, dampen a clean cloth with cold water and dab at the area you're working on gingerly. Don't make the mistake of rubbing fiercely - this will only cause the stain to spread and worsen further. Once the area is nicely dampened, use a spatula to spread the poultice mix onto it. Avoid applying it too thickly - a thin layer that you can't see through is satisfactory.
Once the poultice has been applied, cover the area clearly with a plastic wrapper, taping it down at the edges. Leave to set for 24 hours before removing the plastic wrapping and scraping off the hardened poultice. Use cold water and a fresh clean cloth to wipe the area once again and remove any residue. You should now find that the urine stain has been completely removed and the odor has disappeared.
