Backer rod is a small foam rod or cord that is used to fill joints
between tiles or other pieces of building material.
Builders and contractors often use this tool initially in grooves
or cracks and then they apply mortar, sealant, or chinking around
The rod adds stability, precision, and also typically save time.

Closed Cell Backer Rod is a round, flexible, closed cell
polyethylene foam with an exterior "skin" used as a backing and
thickness control device for elastomeric and other cold-applied
sealants. The Backer Rod becomes an integral part of the joint into
which it is installed, and therefore is available in a range of
diameters to accommodate joints from 3/16" to 1-5/8" (5 to 41 mm).
It limits the depth of the sealant, thereby preventing excessive
use of the sealant, which promotes proper joint design. Because the
sealant will not bond to the "skin" of the rod, it can stretch and
recover with joint movement, with minimal stress being put on the
points of adhesion to the substrate.
