How To Caste a Prop Engine Block Using FlexFoam® iT! 17

FlexFoam-iT!® 17 Part A is measured out. Then, FlexFoam-iT!® 17 Part B is measured out. The mix ratio of FlexFoam-iT!® 17 is 1A:2B by volume. A few drops of So-Strong® black pigment is added to the Part B. The pigment is pre-mixed into the FlexFoam-iT!® 17 Part B. The FlexFoam-iT!® 17 Part B with pigment is dispensed into a mixing container. The Flex Foam-iT!® 17 Part A is added.

The foam is mixed using an electric drill equipped with a turbine mixer. Then, the mixed foam is dispensed into a new, clean mixing bucket. The foam is mixed again to ensure a thorough blend of Parts A and B. The FlexFoam-iT!® 17 mixture is then poured into the silicone mold. The backer board is held in place using clamps. Back pressure from the board will improve the foam surface detail. After a few minutes, the foam rises through the holes in the backer board.
