Observing Pressure-Treated Lumber on a Construction Site

As I'm working on this job today, removing vinyl siding from a wall, I came across something that caught my attention. As I was pulling out the roofing nails or shingle nails, I noticed that they were quite rusty. This sudden rustiness led me to wonder what could be causing it. Upon further inspection, I realized that there might be pressure-treated plywood used on the bottom edge of the wall, whereas the rest of the wall didn't have any.

To verify my theory, I decided to open up the wall and see if I was correct. This handheld video is meant to show you how we always talk about using hot-dip galvanized or ACQ deck screws when working with pressure-treated projects. In this particular instance, I'm on a construction site where I came across some unusual rustiness.

As I observed, my siding nails were present at the bottom row of the wall and began to rust suddenly. This led me to suspect that there might be pressure-treated plywood beneath the surface. To confirm, I decided to cut some foam to access the interior of the wall. Upon cutting through the foam, we found that indeed, there was pressure-treated lumber on the bottom edge of the wall.

This discovery highlights an important issue with using standard siding nails on projects involving pressure-treated lumber. The nails were present throughout all other rows above but only began to rust at the bottom row. This difference in rustiness becomes more apparent when comparing one nail with another, one being new and appearing almost brand new while another shows signs of rust.

A closer examination of both sides reveals that the rusty nail on the pressure-treated side should be identified as such due to its characteristics. The presence of a small amount of rust indicates that it may have been in place for about five or six years. Comparatively, other nails on the same wall do not exhibit any signs of rust.

Upon further inspection at another part of the joint, I observed that this particular nail shows virtually no signs of rust. This reinforces my theory and serves as a concrete example for why using hot-dip galvanized or ACQ deck screws is essential when working with pressure-treated lumber. These types of fasteners are designed to prevent corrosion in projects involving treated wood.

This video serves as an example of how critical it is to use the right materials when dealing with pressure-treated lumber. Using standard siding nails can lead to rusting issues, which could compromise the integrity of a project. It's always best to be aware of such potential problems and take necessary precautions to avoid them. By doing so, we can ensure successful outcomes in our construction projects.

In conclusion, this video aims to illustrate an important point regarding pressure-treated lumber and how using hot-dip galvanized or ACQ deck screws is beneficial for preventing rusting issues.

come across something that we think you know average DIY or might be interested in so I'm just on a job today removing vinyl siding from a wall and as I came down the wall I started to notice that the roofing nails or the shingle nails that I'm pulling out were quite rusty all sudden at this bottom row of siding and I got wondering I wonder what that's all about then I realized I bet you there's pressure treated plywood used on the bottom edge of the of the wall and not up above so you know this we're gonna open it up and see if I'm right but this kind of just shows you how we always harp about using hot-dip galvanized or acq deck screws you know those types of fasteners on your pressure treated projects when you're using any kind of pressure treated wood so it's just a handheld video so you have to kind of bear with me but I'm just gonna cut some foam on here and we'll just see we'll just see what's going on with this wall so so yeah that's that's exactly what we've got going on pressure-treated lumber down here my siding nails were right here as you can see they would have been in that all the other rows we're up into here which didn't look rusty here's some of the nails laying right here you can see the difference ones on the right hand side look like they're basically new and the other ones are getting really rusty so you can kind of see what I'm talking about and actually here's here's some nails this nail here should I think being the pressure-treated and one up here so let's just pull those out so you can actually this is hard to deal holding on to the camera give me one second here's our nail so yeah you can see here this one isn't quite as bad it may be really quite in the pressure-treated but you can see that it does have a little bit of rust on it on the siding I think was on for about five or six years let's go up here this so this nail here looks really good there's no rust on that at all so so for whatever reason this one down here wasn't quite as bad yeah it was kind of I'm already at the joint so maybe just interested was bad but typically so anyways I just wanted to quickly show you that and give you a bit of an example on why we always talk about using hot dip fasteners or AC q type deck screws on your decking projects and anything else that uses pressure-treated lumber so anyways like said just something to watch out for and pay attention to thanks a lot for watchinghi Shannon here from host improvements comm and I'm just gonna give you a really quick video this is just one of those videos we do where we're on the job
