Using this specific product

How to check readiness
Check the coolest or thickest part for firmness before sanding, demolding or loading. The data sheet gives a pot life of 42 minutes for 100 grams. The data sheet gives 5 to 6 hours to cure to a solid in a thin film. The data sheet gives 5 to 7 days to reach working strength.
