Unless the "patch" is a small area (2" x 2"), why would you want to patch it. If the area is a larger area, invest the money and use real concrete, or have a professional quote and do the job. I suspect the reason for the deep patch is you had some foundational problems. If that is the case, don't "cheap" the repair. Good Luck
I do not know the answer to this question as it is nothing I have used the product for. I would suggest you try to google the manufacturer and ask them.
No, QUIKRETE® Vinyl Concrete Patcher is not designed to be applied dry and sprayed with water. We typically recommend QUIKRETE® Hardscapes Polymeric Joint Sand (No. 1175-56) for joints ½ inch to 2 inches wide or QUIKRETE® PowerLoc Jointing Sand (No. 1275-57) for joints that are less than 1/2 inch wide. Both products are polymer modified sands that once placed and watered will harden as it dries and resists erosion, weed growth, and insects. If using QUIKRETE® Hardscapes Polymeric Joint Sand or QUIKRETE® PowerLoc Jointing Sand be sure that the pavers are completely dry before the application. After placement of the material, make sure to remove any dry material left on the paver surface prior to the application of water, because this could cause hazing. Also be careful not to wash the QUIKRETE® Hardscapes Polymeric Joint Sand or QUIKRETE® PowerLoc Jointing Sand out of the joints onto the pavers while applying the water.
Yes , you need two inches thick
I believe up to 28 to fully cure. I had a good stretch he of sunny warm weather. You Don t want to hot or cold and definitely not before a rain shower. My concrete pad patch had 14 solid days or better to set.
Yes, you can apply Quikrete to repair a crack in your driveway, so long as you follow instructions on the package.
Since there is likely to be movement between the house and the driveway/sidewalk this would not be the best choice. A flexible concrete crack/joint sealer would be a better choice.
No, this product is not recommended to be stamped.
No. If you can I'd jack the patio up if possible. It'll continue to sink. I used this on a crack on my porch, and it never quite held. But it held for the 6 months I needed it to but then it broke up. I think this product is probably much better if you're patching an entire area to where it can be a "solid" cover, but once you simply just add it to concrete, it doesn't take well. Maybe for planters, etc?
This is the right product
