How are you patching your 1 hour rated walls?

Today’s Topic- How do you properly patch a one hour rated wall?

Hi everyone. I hope you are doing well despite the lock down and virus. We are breathing easy over here and I pray that the same is true for you, your family and your teams.

I have been capitalizing on this time to develop a new skill and I can’t wait to share the results with you. It will be some training videos.

One of them will discuss the difference between regular drywall and type X, another will talk about type X drywall vs type C.  Since that is all coming down the pike in the next week or two, I wanted to share somethings that will compliment that discussion.

Once you have built a rated wall at some point in time its likely SOMEONE will poke a hole in it. This could happen during construction if someone decides to relocate a pipe for example.

So how do you patch it. If you ask the Gypsum Association, this is how you should patch a rated wall. Please take a moment to look over this so you understand. One of the videos that will be coming  will talk about how rated walls are tested, but the one that I hope to get to you first will talk about the difference between regular drywall and we will have a complex discussion about fire dynamics that is actually kinda fun. For now, I will leave you with this from US!

Next week we will talk about how to patch a two hour rated wall, because those are really different.
