How to Patch a Chimney - EASY!

If you're having issues with your chimney and need to patch it yourself, this is how you do it! This vinyl concrete is extremely easy to use and is designed not to crack. Quikretes manufacturing instructions outline exactly how to use this product and is a big part of what my video goes off of.

This specific chimney is made out of cinder blocks and was cased with some sort of concrete. There have been multiple patch jobs on this it appears as I can see some fiberglass strands in the surface concrete here. This same type of patch that I'm using will work with any type of brick and concrete chimney.

The steps are as follows:
1) remove any loose pieces
2) use a wire brush to further remove debris and moss
3) use a soft brush to clear the dust and dirt
4) mix the mortar
5) spray water in areas you are about to apply vinyl concrete to
6) apply concrete and let sit for 15-30 minutes
7) use a float to smooth out the concrete
6) keep the concrete wet for a few hours if possible to prevent cracking and improve bonding.

That definitely should be rebuilt. There's likely internal deterioration as well.
Thank you for sharing 👌🙏

Thanks for the tips. I need to do this and your video is a huge help!

Someone is always a critic but this is a much better option than $4k. That price is ridiculous.

[danielbourque]

This is exactly the type of video I needed. Thank you so much for your knowledge. You earned my subscription. Look forward to more videos. Hope my support helps or channel and your family

My chimney leaked a little bit into my garage last night here in NY with that bad rain. I was going to hire someone to do the same thing but I think I’ll attempt this.

[Curt-docl]

I am a contractor not masonry Overall good job anything is better than it was May be worth waterproofing also. Good work

[brentbarger]

What do you think about putting a wire mess up first for a mortor bed?

[TimetravelerMN]

I will probably need this at the top if I decide to do it myself but I think for the stucco down the front of the chimney it will need different material thank you for your video because I know it’s hard to do the work then move the camera and fuss w the camera it’s annoying but you did it for the people.

I'm curious if you have updates for how this turned out. You didn't do anything with the flashing at the roof, is that because the original flashing was ok? And did you put any kind of sealer on this afterward? Thanks for making this video! I'm trying to learn about chimneys as we buy a house that is going to need work done on the crown.

[pegtop]

Does anyone wrap the chimney in reinforcing wire or chicken wire to add strength and hold the mortar on better?

[jltefft]

Thank you. I too got a quote for $4 K. Very good video.

[nixie]

I have a leak still after the roof was redone and flashing, I think its the chimney I need to go on the roof and do this. Thanks. Fingers crossed it is my problem.

Anybody know why he used "vinyl' patch vs straight mortar. I have the same chimney issues. Thx!

[PropheticForcast]

Why did you use vinyl kwikcrete as opposed to traditional mortar?

[paulc]

I appreciate your video and work effort, but this is just a bandaid on a stich wound. It seems to me that all chimney crowns should have a custom fit stainless steel box cover with holes cut out for flues and fasten in place, and a high temp flexible caulk sealer around perimeter of flues.

Question: As the fire burns (in the fireplace?), the chimney will expand and contract. Did any cracks form in the Quikrete surface over time?
I am about to restore my hundred-year-old chimney that has been painted, tarred, and gooped. All those coatings have allowed the mortar to rot and turn to sand on the North side especially.

[ronesposito]

Can you paint this afterwards ? And if so does it have to be a special paint ?

[JoseNavarro-mtdk]

So I need to do some repair to my chimney on the inside. I need to put mortar, does it have dangerous fumes ?

[jonathanesley]

Thank you for the info I have a similar problem

[mosesaltair]

I have a rental I'm getting ready to put to market and the chimney needs work. Masons said thousands of dollars to rebuild from roof line. Needless to say I'm the proud owner of some vinyl cement and mortor now and going to see how well this works. Any updates?

[damiondobney]

good stuff mon.... am going to do mines weekend
