Question 1

1. What’s the best way to store silicone sealant?

Accepted Answer

If you’re wondering how to store silicone sealant, here’s some great advice from the brand Soudal:

“Store sealants in a cool and dry location where the temperature is between 5°C and 25°C. When the product has been opened, seal the nozzle as much as you can to ensure that air humidity cannot come in contact with the product, which would result in curing inside the nozzle/cartridge.”

Every product is different though, so make sure you check the packaging for specific instructions.

Question 4

4. Can I use the same sealant for windows and doors?

Accepted Answer

Accepted Answer

Question 6

6. What’s the difference between a sealant and a sealer?

Accepted Answer

Sealants are flexible materials used to fill gaps and joints, preventing air, water, or dust from getting through. They're common in bathrooms, kitchens, and around windows. Sealers, on the other hand, are surface coatings that protect materials like concrete, stone, or wood from moisture, stains, and wear. In short: sealants block gaps, while sealers protect surfaces.
