Definition & Meaning of "putty"

What is "putty"?

Putty is a soft, flexible substance used in construction and repair for filling gaps, sealing joints, or attaching materials. Typically made from a mixture of ingredients like linseed oil and pigments or from synthetic materials, putty can be used in various applications, such as window glazing, patching walls, or securing tiles. When applied, it can be shaped easily to fit different surfaces, providing a smooth finish. Putty is valued for its ability to create a strong bond and its flexibility, which allows it to accommodate slight movements in materials without cracking.
