How To Make a 2‑Part Mold of an Architectural Bracket
Step 17: Pouring Foam‑iT!™ 10 Slow Rigid Polyurethane Foam
Foam-iT!™ 10 SLOW is dispensed 1A:1B by volume and mixed thoroughly with a drill and turbine Mixer attachment. The material is poured into the cavity and allowed to expand. Multiple small batches of foam are added to fill the cavity as need. A board pre-drilled with vent holes is placed over the mold box opening and secured to create back pressure. The material in the assembly is allowed to cure for 2 hours at room temperature (73°F/ 23°C).
