when it comes time to caulking the table we're at the tub area what you're going to need is latex based quark which is designed for bathrooms I prefer one with Microban in it which is a chemical that deters mildew and mold from growing you're also going to need a damp rag once you begin caulking what you want to do is just gently squeeze your handle and move the gun at the same rate as you apply pressure to your trigger you don't want to put too much clock on once you've applied the bead of caulk what you want to do is take a damp rag wet your favorite and then simply smooth the beat out with your damn finger what you need to do is stop every 12 or 18 inches or so and wipe off the excess onto the damp rag and you'll see that you have a nice clean corner
