🇬🇧🇪🇸 sealant - sellador : English Lesson

Meaning of "sealant" ("sellador"), detailed definition, and a short video lesson below.

A sealant is a special goo, paste, or liquid that people use to protect things from getting wet or dirty. It can be painted or spread over a surface, like wood or stone, to keep water and other liquids from soaking in. It can also be squeezed into the tiny spaces or cracks between two materials, like between tiles or around a window, so that nothing leaks through. Sealant works like a waterproof shield or a tight plug that keeps out water, air, and sometimes even bugs.
