Discuss Sealant Elasticity for Joint Movement

samples in front of us in front of us that I'm going to stretch and mess around with but you know the question is you know this stuff is like you know pretty stretchy you know how much elongation or elasticity do you really need in you know a caulking I mean houses do they really move that much and then you know come on just a bathtub really move that much so let's hear it Nate you see companies advertise you know 250 stretch and like so you know we say 700 stretch right the answer to how much you need is it depends on the size of the joint right so I'm gonna give you a scenario okay let's take a 12 foot piece of vinyl siding okay you can look this up you can Google it in the course of a day that can move up to half an inch okay okay so let's say your joint that you left for the caulking in your butt joint is a quarter and a quarter inch you're asking it to effectively double right because it's got to go from a quarter all right it's going to move to a half so what if you left an eighth of an inch instead of a quarter inch now you need it to move 400 percent right right now that's just one time right when we're talking about 700 percent stretch we're saying you can move this to seven times its initial length once and that's why it's gonna break but you're asking a sealant to do that every single day thousands of times thousands and thousands and thousands of times so a little wiggle room it's not a bad thing right yeah you know we can keep this
