This worked great and was easy to do
I was putting up Christmas lights and noticed the concrete crown area of my chimney was cracked and really weathered. It is original to my house and has been in place since the house was built in 1963. I sealed the bigger cracks and loose pieces with an outdoor adhesive caulk and let that set up. The directions say to use duct tape to mask off the chimney. I used 3" masking tape and it worked fine. I brushed off the dirt and loose debris and then using a spray bottle, misted the concrete with water like the directions say. This stuff is ready to use right out of the bucket and has the consistency of frosting. I brushed on a thin layer first and once that was done, repeated with a heavier and final coat. It came out fantastic and the crown looks new. I masked off about 1/8" up the flue and also down the bricks to allow a good seal between the two with the crown. My crown is about 2x3 and I only used about a quart to a quart and half out of the gallon bucket. I have added some pictures here to the review but wish I had a "before" picture to show so you can see how well this works. My chimney is restored and will last a long time.

No issues with the arrival. I am fairly pleased with this product. I would say that the 40 square feet of coverage is a stretch. The surface of my crown was fairly rough and was approximately 18 sq ft. I had about 10% left of the material after 2 coats, the first of which was as thin a coat as I could manage. I did follow the recommendations and installation instructions closely. I used quick drying mortar to make the chimney crown as even as possible and to fill in cracks. I did apply painters tape to the flue but really found that it was not necessary. All total I had a about 2 hours in the repair (removing loose pieces, scrubbing the surface with a steel bristle brush and general cleanup). I was quoted $700 by a chimney sweep to do this. My total cost was $75. The product is the consistency of tile mortar but goes on okay. It takes some work to get it all applied evenly and somewhat smoothly.

Stuff that actually works
Used this stuff to refurb the 3' x 5' chimney crown on my parent's house. Cleaned up the existing with a stiff poly brush and let a day of rain remove the ensuing powder of UV disintegrated mortar. High temp caulk around the clay flue liner and then this compound as directed. Great stuff. Seal is complete and ready for winter. Start with a dry crown and mist with a spray bottle of water as you brush on your first layer. Give it an hour and put on the second coat. I still had about half the bucket left over. Has the consitency of thick pancake batter and needed no mixing upon opening.

on 2017-11-11 Save $300 using this product doing it myself! Very Easy!
I had a Chimney Sweep come out and do a Chimney Inspection for $100. Among the items recommend to do was to repair/seal the Crown Cap which had several cracks and in poor condition. They quoted $300 to do the Crown Repair. I first used the Quikrete Quick Setting Cement 10 - 15 Min 10 Lb
to repair the cracks on top of the crown and let that cure. Then I used the ChimneyRx Brushable Crown Repair gal
I followed the easy directions, first with a thin coat after spraying it with water. Then added a second thicker coat. It looks great and now all the cracks are sealed up It matched perfectly for our colors of the house. It is an white-gray color once dried. Saved myself a ton of money doing myself! The Chimney Inspection also recommend us to waterproof the bricks, I used the ChimneyRx Masonry Fireplace Chimney Water Repellent - 1 Gallon
which they quoted at $200. And used the Chimney Rx Elastomeric 1/2 Gallon
which they quoted for $300.

Great product, saved me $$ from hiring a chimney sweep who wanted hundreds.
Excellent production. Chimney sweep wanted to charge me $250 for him to buy a 5 gallon drum to do this as well as another $150 to do the work. While I'm all for people making $ it was clearly a rip off considering I bought this and did it myself in about 30 minutes and used maybe 1/5th of the 1 gallon bucket. I started with clearing the existing cement with a stiff wire brush and then wet the surface lightly. After the prep work I started with a thin top coat which I let dry for about 10 minutes and then laid on a much thicker second coat. Since then I've noticed no issues, no cracks have returned and the water runs off much easier.

Arrived quickly. Product consistency is like thin drywall compound, but brushes on fine. A bit gloppy, but no problem. Youtube video showed the product as being white. I was only going to put it on the top of the cap because of this, but when I opened it up, it was a light gray. A very good match for concrete cap. Ended up applying it to top and sides. When looking from below, it just looks like the concrete cap. I also did not apply the tape to either the flue or the brick and had no problem painting a straight line without it smearing all over.

Excellent do it yourself product. Save money!
Older chimney with small cracks at top where stack comes out. Water was getting in to the flue and dripping inside. Up on roof to inspect found small cracks. Contractors wanted hundreds of dollars to fix. I got online and found this product on a you tube video and asked around. Contractors don't advertise this product because it is so easy for a homeowner to use and apply it. Check out you tube video and you will see just how easy and what a great product this is. We did the complete crown and neighbors even though we got a brand new one because it goes on and looks so well. Buy a metal brush, medium and large width paint brush and thick painters tape and a small spray water bottle for the prep and application. No more leaks and it was actually a fun no stress project for my wife and I. We bought 2 tubs not knowing coverage area and only used 3/4 of 1 tub for a crown with 2 stacks.

This was a terrific order. Although not a Prime item, I received it in two days. It was much easier to apply than expected and set up quicker than expected but not too quickly...on a sunny day with a temperature of about 80 degrees.. It looks quite good after setting up for a couple of hours and time will tell how well it ages. I used it on a two chimney crown and used about 2/3s of the container. Our house, built in 1728, has seven fireplaces and three chimneys. This was the lowest and the one that services the heating exhaust, on which I had to replace the eroded flue liner - hence the crown repair. Although I have no idea as to its performance over time, at this point, I would purchase and use it again.

Great stuff and well worth the price.
During a prolonged rain this summer I began hearing a dripping sound inside my fireplace. Further investigation revealed that the crown was going to need repair. The house was build in the early 70's and although the crown still looked good numerous surface cracks were showing. I followed the instructions and had this job completed in an about 2 hours. It rained about 4 hours after the job was finished and luckily the product was dry. Have not seen a drip since.

Easy DIY Chimney Crown Repair
Last year my chimney sweep mentioned that my chimney crown was looking worse for wear and mentioned that he could recoat the crown or, since I was fairly handy, he recommended this product. Application was simple - I used chip brushes for the close-in work and a deck/fence brush for the wide spaces. I purchased the brushes with the intent of disposing of them when I finished rather than trying to clean the crown repair off of them. The bucket easily did two coats of repair work with 1/4 bucket left. If your chimney crown needs some work I recommend this product (as does my chimney sweep).
