Question 2

What is the minimum temperature to use Advanced Silicone 2 Window & Door Sealant?

Accepted Answer

The minimum application temperature for Advanced Silicone 2 Window & Door Sealant is 32°F (0°C). Applying below this threshold will prevent proper curing and the bond or seal will fail.

Question 3

How long does Advanced Silicone 2 Window & Door Sealant take to cure in cold weather?

Accepted Answer

Cold temperatures significantly extend cure time. For every 18°F (10°C) below 70°F, cure time approximately doubles. A product that takes 24 hours at 70°F (21°C) can take over 48 hours at 50°F (10°C). Enter your temperature in the calculator above for a precise estimate.

Question 4

Does humidity affect Advanced Silicone 2 Window & Door Sealant cure time?

Accepted Answer

Yes. Advanced Silicone 2 Window & Door Sealant has an optimal humidity range of 30–65% RH. Below 30% RH curing will stall. Above 70% RH the surface may skin over while the interior remains uncured, producing a weak bond.
