Closed-cell, low-expansion foam is awesome and will eliminate the need for backer rod and multiple layers of caulk. It is the method most Pros prefer.
You got it. .... I'd only clarify that a solid, continuous bead of the foam is necessary, as is exterior caulking.We have several cans of Great Stuff foam for doors and windows. Would this be considered closed cell? So you would spray the foam in and then re-apply the inside trim/stops? Backer rod and caulk are unnecessary?
Good idea... Lastly, I'd recommend buying yourself a halfway decent caulk gun, and don't be afraid to pick up some speed as you lay the bead. The key is matching the pressure that you are squeezing with the speed that you move the gun. If you try to be too careful and go to slow, you'll have no chance. That is the #1 mistake that I see.Lots of great ideas, thanks a million! I'm making up some "test corners" out of 1x scraps to try out the different techniques and see what works best for me. Practice will hopefully make perfect.
If you lube it up well enough the first time, it won't stick to your finger at all... I have to say, I've never gotten the taste of quad in my mouth, although I'm sure its been a healthy cocktail of lead dust and all the delicious carcinogens in the caulk.I’d rather spit on my finger than lick it, that’s some nasty tasting stuff and that flavor lingers around for quite awhile too. :huh:
