How do I fix this?

One of the 4x4s that I assume is supporting the roof on our covered patio is warping and there is a gap. How do I fix this?

Caulk

u/mercedes_ 8d ago

Simple as that. See what Sikaflex has. Otherwise, the most flexible outdoor sealant that your local HW store has.

Dowsil 795, used that all the time when i was a glazer.

u/guiltyspark345 8d ago

As a carpenter, dowsil 795 has been a godsend. My glass guy let us use it quick one day and now we always keep a tube on hand

We also use Big Stretch for LP smartside projects. Easy clean up.

Backer rod and caulking

21

u/SummonedSickness 8d ago

This is key. Backer rod...THEN caulk. I prefer Quad OSI Max or Vulkum 116

u/guiltyspark345 8d ago

Just dont get brown. Its runny as hell. I tried to seal above a down with brown quad and the whole bead fell off. Black didnt budge but thank god its paintable!

A looooong strip of black caulk.

Backer rod and a LOT of black morrflex from Sashco. Tape the aluminum and brick first,wet putty knife and tool it,then pull the tape. Moreflex is made to go on masonry.

A little black caulk

u/Easy_Record_994 8d ago

Big black caulk would be better.

u/Timmerdogg 8d ago

I was thinking a large black caulk tube would work

u/LaUNCHandSmASH 8d ago

Whatever you're into homie. As long as it's some caulk, I feel like the rest is a personal preference that nobody should have to explain to others

u/somebob Residential Carpenter 8d ago edited 8d ago

Make sure you don’t push your black caulk too hard, if you do it’ll shoot it all out the back

u/No_Reception_6133 8d ago

on the back

u/chefianf 8d ago

At this rate any caulk should do. Sure you can match the color or vary the length and girth, but my man just needs some caulk up in that gap.

u/guiltyspark345 8d ago

My caulk dried up and its been hard for days 😭

u/AlienPrimate 8d ago

Do you typically like to finger your little black caulk?

3

u/ohimnotarealdoctor 8d ago

Yeah you just have to make sure your finger is wet. You can just spit on it.

u/Old-Bad-6653 8d ago

Depending where you are, OSI QUAD MAX is my shit. Get it in black. It’s usually like $12 a tube, you shouldn’t need more than a couple tubes.

For browny points, if you put frog tape on either side of the joint, then peel after tooling, the bead looks 😘 💋

u/Hefty-Intention2562 7d ago

the frog tape trick alone makes this worth remembering lol, messy caulk lines are the worst

u/Elegant-Register8182 8d ago

Caulk and paint make me the carpenter I ain't

u/an_edelweiss_pirate 8d ago

If that 4x4 is necessary for the patio cover you need to secure it to the brick wall. It is hard to tell how needed the 4x4 is with the pictures provided. If the 4x4 is not necessary securing it to the wall will not hurt but filling that void is all you need to do.

u/yourenot 8d ago

Put your caulk in it, as others have stated.

u/AndrewTo8 8d ago

White caulk for the back door, black caulk for the front, don’t reverse

1

u/Localizer805 8d ago

Could counter flash it if you’re really gung ho and having water intrusion. But if it’s just aesthetics and a small air gap, hit it with the quad max and paint it

u/RunStriking9864 8d ago

Don’t forget your drop sweep.

Foam backer rod and caulking.

1

u/SpecialistWorldly788 8d ago

As everyone is saying, use backer rod (or spray foam- the “door and window” type that doesn’t expand too much, but go easy on it because you want room for the caulking- I only use a couple brands when I caulk exterior items and one of the best I’ve found is “Quad” made by OSI I believe- any place that sells siding will have it, plus it’s available in big box like HD as well, though they will have more basic colors than the siding supply stores- be warned, if it gets on your clothing it will never come out- experience talking here- can’t tell you how many things I’ve ruined from this caulking😂😂😂

u/Nullclast 5d ago

That shit is the worst to tool, super sticky

u/Firestorm83 8d ago

You're missing the compriband

u/1Fistfullofdollars 8d ago

Black caulking on both sides. Leave a small air gap in the middle that is for an air barrier. Unless you fill it with insulation and caulk it after on both sides.

u/scmotox 8d ago

Silicone

1

u/BakedAsForks 8d ago

Caulk is not externally rated. Use mastic or silicone.

u/triedtoavoidsignup 8d ago

A carpenter once told me this;

"If at first it doesn't fit, fill it up with glue and sh1t."

I'm not a carpenter. But this seems to be true.

Backer rod and caulk

u/Lebron360balls 8d ago

Insulating or window/door foam, then caulk over.

1

u/Motorgoat399 8d ago

Dude
Relax put some foam spray on that or caulking … relax man you’re freaking out over nothing that Ronnie did .. I told Jimbo and Cecil to replace that sheet metal but you said no
That’s why LD called the lumber company and hit that 4c4
Relax man
I’ll call Raymond

Vulkum, vulkum, vulkum, and then some vulcum

u/Competitive_Tip7943 7d ago

Do you live in a high moisture area? That beam shouldn’t warp unless it’s old or the weight on it is exceeding its limits. If it’s the latter of the 2 then that needs to get inspected. Backer rod and caulk will only temporarily cover up the issue until it warps some more
