• Ideal: 70°F, <60% humidity
• Working range: 65–75°F
• Cold = thick, bubbles
• Hot = fast cure, risk of yellowing/cracking

Dispensing & Mixing

• Mix ratio: 1:1 (volume) or 1.11:1 (weight)
• Do NOT alter ratio
• Mix only what can be used in ~20 minutes
• Max recommended mix: 1 gallon

• Transfer and mix again
• Do not whip air
• Let sit briefly to release bubbles

Application

Coating Thickness

• Max 1/2" per coat
• Layer pours for thicker builds (4 hr between coats)
• Excess thickness causes heat defects

Small Castings

• Max 2" depth for ≤10 oz pours
• Layer for larger volumes

Working Time

• Pot life: ~10 minutes
• Working time: ~30 minutes

Pouring

• Coatings: pour in S-pattern, spread evenly
• Castings: pour slowly in one location

Bubble Removal

• Let sit 10 minutes
• Use heat gun/torch 6–8" above surface
• Do not overheat

Cure & Finish
