In my opinion, if you gotta use backer rod on a new house under construction,(with the exception of concrete slabs);Chris Johnson said:Sealing between the window frame and rough opening? Spray foam. Where the exterior facade abuts the window, backer rod and caulking.
I don't think I have ever seen a bucket of caulk? What do you mix it with?I hear you
In my area we are mostly brick veneer. And a lot of time stone. We keep it back 3/8-1/2" from the window, old habits. Backer rod then a good 3/4" bead of caulking that has been mixed. I won't let a guy who shows up with a box of tubes caulk a new home. I want to see a pail of caulking mixed up, fill the gun, various size tips on hand, and something other then his finger to tool the joint
BM knife grade is a fabulous sealant in a can as well as the 2 part polys I use for control and expansion joint work.I don't think I have ever seen a bucket of caulk? What do you mix it with?
Yeah, mine are usually an 1/8 or as little as I can cut the tip of the tube66 Shelby said:I didn't either. I learn something new every day, although if I had a 3/8-1/2" joint on a new build I would probably get run out of town. That's not acceptable here - 1/4" is the max.
