You're supposed to wait 24 hours before applying sealer to let the stone fully dry. It might feel and look dry but water seeps into porous stone and takes a lot longer to fully evaporate, and you want that because you want the sealer to get into the pores and it can't do that if they are already filled with water.
They suggest once a year but it depends on many factors, best to just test your stone every few months. If you use acidic cleaners (don't) that have citrus or vinegar (pretty much all of the pre-moistened wipes), or if you frequently cook and spill acidic foods on them, that can quickly erode the sealant. Just put a few drops of water on it and wait a couple of minutes, if it still beads on top of the surface you're good. If the water absorbs into the stone then you need to reapply. Sealing granite is not absolutely necessary, most folks never seal their granite counters and they are fine. Perhaps if it is a very porous light colored stone and you have really hard water or you constantly allow various liquids to sit, you could get a stain, but even then there are simple ways to remove stains if that happens. The reason you want to seal your granite counters is because they are much easier to clean, and makes them more sanitary (food safe) by not allowing bacteria into the pores. Two things not mentioned here: 1. You should allow the granite to dry for 24 hours before applying any sealant. It might seem dry but there is still water in the micro pores and that will prevent the sealant from properly setting into the stone. 2. To clean and sanitize use soap and water, or if you really want to sanitize use a 60/40 mixture of isopropyl and water.
Dude this wont do the proper sealing job…prove it, you need proper professional and not retail domestic sealants ….just drop lemon or any acidic product onto the counter and it will leave an etch mark and a stain if left for too long .

Can I use it on headstone?
Can this seal other surfaces besides granite
How often do I need to seal and reseal?

Thank you! This is great. I really appreciate your thorough reply.
Can't hear a damned thing over the reverb during the important parts. Need a lapel mic or something.
