Can Flex Paste be used as caulk?

Flex Paste is a powerful tool for sealing and waterproofing, but can it be used as caulk? The short answer is yes! Flex Paste’s thick, durable formula makes it a great alternative for filling gaps and cracks, sealing window and door frames and more. Flex Paste in a cartridge works with a caulking gun, giving you pinpoint precision for your projects. Keep in mind that Flex Paste is thicker than silicone caulk, so it may take longer to apply and cure.

We also offer Flex Caulk, which is a hybrid polymer-based caulk. Flex Caulk is excellent for caulking bathrooms, kitchens, baseboards, windows and more, without the need for a caulk gun. Many types of projects could work with either Flex Paste or Flex Caulk, so the product you choose will depend on the type of project you are taking on, as well as your comfort level using a caulk gun.
