This will not be an article that is too in depth but probably helpful none the less. In the How to Spray Epoxy article, I mentioned one “when” you should spray. That was determined by how much epoxy it will take to spray your pond. If you do not have enough area to cover, the rental of the equipment, the set up and clean up time and the bit of Pond Shield epoxy you will loose in the system will cost you in the end.
However, there are times when spraying even a smaller area than 8 quart and a half kits (3-gallon kit) will cover is essential or at least food for thought. Those are areas in which the ponds surface is so rough that trying to squeegee or roll the epoxy onto them will cost you a lot more in the long run than the set up or clean up time or the loss of a little bit of epoxy.
I have seen ponds that people have told me are pretty smooth that really ended up looking like a broom finish. These are the worst areas to try and squeegee or roll. The reason is that surfaces like this have very accentuated peaks and valleys. So as you squeegee 10 mils over the peaks of a surface like this that has 30 mil deep valleys, you are essentially applying 40 mils over the valley areas. That is a serious waste of material!
So spraying an area like this would be ideal. Also, you might consider spraying a waterfall area. Waterfalls are sometimes difficult because of all of the uneven surfaces they have so trying to brush epoxy on before it cures in the container you’re carrying around can be a problem. Spraying the clear Pond Shield epoxy on the majority of the surface and then touching up the nook and crannies later is a quick and effective way to accomplish the task.
