How To: Brickmould Door Install 

After installing the 15 layers of OSI Max, repeat 3 more times. Allow to settle and put on 9 more layers to prevent moisture.

Apply OSI QUAD to the OSI QUAD, then seal with OSI QUAD and OSI QUAD

just installed my first door on my home. I appreciate this video, it helped. I did use some DAP 800 for the sill to sillpan and dripcap. THANKS!

Omg this video is asmr this is literally 100% water proof. The only thing I’d change is the way you laid the sealer under the door in lines doing vertically up and down and just 1 going diagonal on the inside so if water gets in I can flow out

I'm installing an exterior door between dining room and garage so flashing tape not necessary. Water is not an issue here, only temperature as the garage isn't heated. I'll put the sill pan directly on the ceramic tiles and concrete lip of the slab on the garage side. The OSI foam is definitely a must as to not let heat out of the house as the garage is not insulated.

I wonder what brand of caulking I need to use.

Great vidieo. The sill pan is a Jamsill Guard. I use them, Great product!,

OMG this is the best video on youtube.... on the subject.... THANK YOU so much

I really like parts of this system. We install thousands of door units a year in Houston.

Excellent tutorial, thanks guys.

Where can I get that head flashing?

Why not just wrap the WRB around the studs and put the tape on the corners? If you have any failure of the caulk then the studs will be exposed .

Should purchase a few more tubes of caulking...

Wouldn't that back bead of silicone nullify some of the usefulness of the upturned rear ledge of the sill pan?

Stupid amount of caulking for a single door
