Holes, Voids and Crevices
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.
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.
White Safety Ring
Pond Shield is packaged in a manner that the kit contents will not spill out during shipping or handling. The white safety rings are pressed on in our manufacturing plant and can be difficult to remove. One method of removing them is to use pliers to grab the lower edge of the ring and pry upwards. Apply this maneuver about every 1/4 inch around the can's lid. The white ring will usually pop right off with this motion, but if you still have difficulty, you can then pry the remainder up with a small flat blade screwdriver. You can discard the white ring after removal and simply tamp down the can's lid to store any extra Pond Shield you may have left over.
Pond Shield has a very long shelf life, in fact years. In most cases long term storage will only affect the hardener portion of your coating and you'll see some separation of the materials that make the hardener up. This is normal. Once you pour the hardener in with the resin and mix it for use, there materials will return to their natural state and the Pond Shield can be used as it was when purchased. For the longest possible storage life, store your kits in a cool dry place with the lids securely tamped down.
Pond Shield will cure if applied at above 52° F. Considering that, you should keep in mind that because Pond Shield has been designed thick in order to hang properly on vertical and upside-down surfaces, it can seem a lot thicker when it is cold. The application process can be a lot easier if you store your kits inside at room temperature for 24 hours before taking them out to the project site. Properly mixing your epoxy will also make it easier to apply. Pond Shield clear can be stick-mixed where the pigmented versions should always be mixed with a jiffy mixer attached to a drill. Mixing with a jiffy mixer will change the viscosity of cold epoxy and make it easier to apply. Pond Shield cures in about an hour at 72° F. Lower application temperatures will retard this process some, giving you longer pot life.
Warmer temperatures can shorten the pot life of your epoxy. Care should be taken at any temperature not to over mix the coating. Stick to the instructions and you should not have any problems. You can also store Pond Shield inside at room temperature just as you would during colder applications. Epoxy that has been stored outside in the sun at 85° F for instance will have a shorter pot life because the epoxy is already heated up. As a rule of thumb, make sure you only mix the amount you know you can apply within an hour or less.
