Always place a roll of paper towels within reach before mixing a batch of epoxy. We recommend using paper towels to clean spills and wipe up excess epoxy. To remove contamination from bonding surfaces, we recommend plain white (non-printed) towels as the ink may be a contaminant that can affect bonding.
It is also good practice to use plastic sheeting (4 or 6 mil) to protect floors and work surfaces from epoxy spills and mask off areas of your project you want to protect.
Epoxy won’t bond to plastic sheeting and will peel off when cured Use small pieces of plastic under clamps to avoid inadvertent bonding. Clear plastic packaging tape also works well to protect clamps, tools and other surfaces where you don’t want epoxy to stick.
