i`ve researched the product and several alternatives. this seems to be the most owner friendly. call the manufacture up and they will describe the various types of techniques of application of the cost of each variant. there may also be another product that my wife can refer u to since she did the last research. these can be applied w/a grout bag; a caulk gun of different sizes; even a caulk gun reloadable from a presurized canister; this ol` house even had a drill attachment that would augar the compound into place w/ little effort. cked w/ my wife and she can`t remember. call triple l log homes in salado, tx. 2549473502. good luck.
