Do you have an older drip pan that is severely rusted, and may contain pinhole perforations through the pan bottom and/or sides?
If you do, as Michael Jackson would sing, “You are not alone”.
Since Pancrete is engineered to be a water-like consistency so it can self-level and flow under coils, it may also be able to go through any pinholes (if not blocked) that are present in the pan’s surface. Many pinholes are so small in size they may go unnoticed.
Panhole Filler prevents Pancrete from flowing out pinholes in older water drip pans. It bridges holes up to 100 mils thick (or to give you a better visual- the size of a coffee stirrer stick). This white product is also engineered for health and environment issues by being non-toxic, and chromium free. Additionally Panhole Filler functions as an anti-corrosive primer to further protect the surfaces from deteriorating.
PanHole Filler is applied at 10 mil thickness on the bottom of the drip pan. PanHole Filler is not a standalone product, it does require a top coat of Pancrete prior to the unit being put back into service. It is also recommended that Clean Bond be used as a cleaner and flash rust inhibitor prior to the use of Panhole Filler.
