Fixing Holes, Pits, Voids and Crevices in Concrete

There are two important things to remember when applying Pond Shield. First is surface preparation, but the second thing is the easiest to skimp on, that is inspection.

After your epoxy coating has cured, you need to take a look at every square foot of your pond to make sure you have coated everything that will be submerged. Sometimes while applying a coating, small areas of your surface area can be missed, like those in the pictures below.

Whether in the form of a little concrete (or whatever surface you are applying to), showing through because the coating was applied to thin, or little holes, voids or crevices, these can all turn out to be potential leaks. You need to make sure that you are not simply applying coating around these areas and calling it a job done.

After your coating has cured and you can move around on it, you should take some of the Pond Shield you retained for touch-up and fix any spots where your surface area shows through the coating and any holes, voids and crevices. Keep in mind that if your surface area has larger holes, you may want to correct them before you apply Pond Shield.
