Which glue gun is better 20w or 40w?
The Wattage Factor When it comes to glue guns, power and heat go hand in hand. More wattage means a hotter glue gun, faster heating, and the ability to stay hot longer while you’re working. A rating of 10 to 20 watts is common for low-temperature glue guns.
What does Hot glue not stick to?
The hot, liquid form of the glue will penetrate woven materials and fill in crevices in rougher surfaces, so that it solidifies in unity with the surface as it cools. Smooth surfaces like metal or greasy and oily surfaces do not offer the hot glue anything to bond within, so the glue does not stick.
What is the difference between hot melt and cool melt glue guns?
Hot melt glue guns and sticks are the strongest and most durable of the glues available but require care in their use as they can burn very easily. Cool melt glue guns and sticks work at a lower temperature and so are safer to use but must still be used with caution.

What happens if silicone sealant gets wet before it cures?
If caulk gets wet before it cures, then the moisture cannot evaporate quickly. This can extend the time taken by the caulk to dry up. In some instances, it may also become difficult to achieve proper adhesion. Too much moisture can also lead to the growth of mold and mildew.
