What Is the Difference between Caulk, Spackle and Patching?

To someone not familiar with each substance, caulk, spackle and patching seem similar, but, in actuality, they have very different uses. Caulk may be easy to use filling small holes, but spackle or patching are better suited for that job.

Caulking was first used centuries ago to close off the seams in wooden boats from water, and is still used to seal gaps and make items water-tight. It is now used to close off joints or seams in various structures to protect them from dust, air, insects and other things, not just water. Caulking can also provide thermal insulation by blocking off a structure from outside penetration, making it a money-saving tool by reducing heating and cooling costs.

The application of caulk also differs from that of spackle and patching. Caulk is applied by a caulking gun from a tube, while spackle and patching are applied with a putty knife, because much more is needed as it is used for larger repairs.

Spackle and patching are similar, but have basic differences. Spackle is used to fill holes, small cracks, and other minor surface defects in wood, drywall, and plaster. It is preferred by most painters to caulk because it is designed to be painted over, while some caulk is not. Patching has similar uses to spackle, but is used for the largest holes and cracks and is shrink, sag, and crack resistant. It is great for heavy duty repairs over drywall, plaster, wood, metal, and masonry.
