The way you moisten the ballast with water, as to not disturb its position, is to use a spray bottle and let mist settle on ballast instead of directly at it. Entire area is wet as if it just rained on everything.
Hello. I try to keep sleepers under blades dry, because if I moist them with wet water, than it will be easier for diluted glue to climb up on the top surface of the sleepers, and in this case blades will be glued to the sleepers. That's why I apply wet water from syringe instead of spraying it on the entire turnout - to keep sleepers under blades dry.
Also, it is very important to prevent wet water from moisting the points (mechanism, which in my video I protected with scotch tape from the underside). If points will be moisted with wet water, it will be easier for diluted glue to get into them and block the turnout. This is another reason to apply wet water from syringe instead of spray.
The glue (half white glue / half water / one prop soap or alcohol ) is merely dropped on the moist ballast with an eye dropper, moving along the track in middle and shoulders of the roadbed a couple feet at a time...
I try to apply majority of glue far away from throwbar area. Because the closer you are to throwbar area, the closer blades to the stock rails, the more risk to glue blades to the stock rails. So I apply majority of glue as far from throwbar area as possible, and then glue flows under sleepers in longitudinal direction and saturates that area.
Besides, since I apply wet water only in one point, I cannot apply glue, moving along the track, until diluted glue, which flows under sleepers, will not moist another areas.
Also, I recommend to use syringe to apply glue instead of eye dropper, because syringe is more precise, and it is important when ballasting turnouts.
I've belonged to 2 MRR clubs in/around Los Angeles,Ca. since 1978 and they've had no problem with ballasting switches this most common way.
Of course, traditional method works, but it requires more caution and more preciseness.
One of the main advantages of this new method is that it forgives mistakes: if you accidentally drop too much glue, high capacity bath under turnout will easily absorb it.
Another advantage is that you can easily ballast complex turnouts, like double slips. Double slips are the easiest turnouts to ballast with this new method (LOL). All you need to do is to pour the glue to this point:
The glue will flow under double slip from this point in all directions, and the majority of ballast will be saturated from this one point.
