Putty

Putty is a material with high plasticity, similar in texture to clay or dough, typically used in domestic construction and repair as a sealant or filler.

Glazing putty is traditionally made by mixing a base of whiting (finely ground chalk) with linseed oil in various proportions.

[3] There are a number of synthetic alternatives such as polybutene-based putties, where the polybutene is a low molecular weight oligomer replacing the linseed oil.

Painter's putty is typically a linseed oil-based product used for filling holes, minor cracks, and defacements in wood only.

Putties can also be made intumescent, in which case they are used for firestopping as well as for padding of electrical outlet boxes in fire-resistance rated drywall assemblies.
