Mastic
Mastic is a durable, flexible sealant material used in construction to prevent water damage and create watertight seals. Think of it as a special type of caulk that's much stronger and longer-lasting. It's commonly used around windows, doors, foundations, and roof joints to keep water out of buildings. When someone mentions mastic in their resume, they're typically referring to their experience applying and working with these waterproofing materials. The term might also appear as "mastic sealant" or "waterproof mastic." It's a crucial skill in waterproofing, construction, and building maintenance roles.
