No. Weicon Flex 310 M Crystal Clear Sealant can be applied using standard caulking guns.  

How long does it take to cure?

Elastic adhesives cure by reacting with the humidity in the surrounding environment so cure time is impacted by both the room temperature and humidity. Assuming 50% relative humidity and a temperature of about 23°C, you can expect curing to occur at a rate of 2-3mm per 24 hours. This is measured from the sealants surface working in.

In higher temperatures and/or humidity, curing will be accelerated. Skin over time is 10 minutes (approximately).
