Fiber Cement Siding Repair
 

I have a hole at the end of one of the fiber-cement siding planks on the
exterior of my house. The hole looks as though someone took a bite out of
the end of the plank, exposing the weather barrier. The plank in question
butts up to the frame/side sill of a window. The hole is a bit smaller than
the size of a silver dollar. Is there a simple way to repair this or is it
necessary to replace the whole plank? Perhaps some type of fiber-cement
patch or putty to fill the hole?

Also, what is the best type of caulk to use to fill in the gaps where the
siding meets the wooden window frame/sill? DIY Help Pages that I found on
the Internet mention ASTM C920 caulk- either acrylic, latex, or urethane.
Does one type perform/last better than others?


Thanks in advance.

Concrete patch would probably work. Even drywall mud (the "add water"
type, NOT premix) would for a hole that small. Roughen up the inside
of the hole.

Also, what is the best type of caulk to use to fill in the gaps where the
siding meets the wooden window frame/sill? DIY Help Pages that I found on

These days they're all about the same - quite long, tho, urethanes will
probably stand up best long term.

Since you mention putty, try Bondo.

Something exterior, climate friendly - pick your poison.
