All log homes need sealant to close the gaps between log
courses. Because even machine milled logs won’t lie perfectly flush against one
another, these sealants are necessary to prevent water intrusion and provide
insulation. These sealants typically fall into one of two categories – chinking
and caulking. Today we’ll compare the applications for both of these sealant
types.
Chinking
This is the type of sealant that has been traditionally used
in log homes for centuries. It forms the characteristic white bands between the
courses in older log homes. Whereas chinking was originally a Portland cement-based
mortar, today it is an acrylic compound designed for extra elasticity and
adhesion. Before chinking can be applied, a backer rod must be placed in the space
between the log courses. This ensures a firm seal between the joints. Next,
Chinking is applied over the backer rod, filling in the remaining gaps between
the logs. The width of the chinking in a given log home will depend on its
construction and the aesthetic preferences of the owners.
Caulking
This type of sealant is only used in modern, machine-milled
log homes. It’s very similar to the caulk you’ve probably used in your bathroom
or kitchen. Whereas chinking is designed to fill broad gaps between courses,
caulk is used to seal narrow gaps. Likewise, it doesn’t require backer rods.
The caulking in a machine-milled home is more or less invisible from a
distance. Caulk is also more elastic than chinking.
