One pump for the resin and one pump for the activator. For use with Professional Epoxy Coatings home epoxy packs. Each pump measures out the correct amount. They make life a lot easier and will last for many packs of epoxy.
These pumps are suitable for epoxy systems of 3 kg or 3 litres and upwards.
The resin pump measures out twice as much as the activator pump, so you only need one measure of each to get the correct mix ratio.
These small pumps are for epoxy systems of less than 3 kg or 3 litres. Unlike the large pumps, these measure equal amounts, so two measures of epoxy should be mixed with one measure of activator.
