Rapid Set Mortar Mix is a high quality mortar that is suitable for vertical and overhead applications. It is ideal when rapid strength gain, high durability, and low shrinkage are desired. Use Mortar Mix for general and structural concrete repair, stucco and plaster repair, one-coat exterior plaster, mortar beds, underlayment, and formed work. Mortar Mix sets in 15 minutes and is ready to drive or build on in one hour. Durable in wet environments, it can be applied from 1\2 in. to 6 in. thick. Mortar Mix is a blend of high performance Rapid Set cement with quality sand. Mortar Mix offers superior resistance to chemical attack. It is non-metallic and no chlorides are added. Mortar Mix allows the repair areas to be painted, coated, or sealed quickly after application. Under dry conditions, water-based coatings such as latex paint can be applied after the product is hardened, which usually takes one to four hours. Solvent-based and impermeable coatings such as oil based paint and epoxy can be applied in 16 hours.

Rated 5.0 out of 5.0 by BEST MORTAR EVER MADE! Trying to save a deteriorating cellar foundation wall from the early 1940's. The walls were power washed and had/have areas that have lost 2" to nothing over the years from water and plain lack of maintenance. I purchased a couple 55 lb bags and started repairing the cracks and loose areas that required mortar repair prior to parging. That time consuming task did cause me to loose 3/4's of the first bag. Then I re-read the instructions and went and purchased the "SET CONTROL" packs and used one per 55 lb bag. Then two per bag. You must add it to the water BEFORE you add the mortar. Once I got the directions correct it went on like butter and I have since used 25 - 55lb bags and almost 50 of the Set control packs. Let me tell you, there is nothing out there that works like this. The walls are like steel and I am showing a few tradesmen the difference between this and just using standard S or N type mortar for walls in this condition. I have also replaced 1 pint of the water with 1 pint of concrete latex bonder and sprayed the wall prior to applying the mortar with bonder following the manufacturers directions for that as well. Finished well with spraying with light water and using a mag float but you must be appreciative of the set time. See the before and after pics of two of the walls we are working on. September 5, 2013
Rated 5.0 out of 5.0 by Great Product The product works just like it say - RAPID. I bought it specifically because it is quick and only mixed what i knew i could use in a short amount of time. Anyone who gives this product a bad review because it is quick setting should go back to school. The products name is RAPIDSET!!!!! April 26, 2014
Rated 4.0 out of 5.0 by Work with small batches at a time This product is fantastic for vertical applications and doesn't need any forms. My only problem with it, which can be a gift and at the same time a curse, is the speed at which it sets. Essentially within 10 minutes it becomes unworkable so you either need to work with small batches or be extremely fast. To that point, even the fastest will find themselves tested when attempting applications of a few square feet or more. Final note, help water cure with a spray bottle for the first hour, as suggested by the manufacturer - and, the use of a waterlogged sponge is extremely useful for smoothing out and levelling work which buys you some time at the back end of the job to about 15 minutes of workable time.

Rated 5.0 out of 5.0 by Great product This mortar mix is exactly what the doctor ordered. It applies smoothly with the flow control added to the water before mixing with the mortar and it was easy to work with. It did dry quickly and hard but that was the desired result and I thought it was perfect for all repair projects! April 16, 2012
Rated 4.0 out of 5.0 by Does the job well-- but sets fast!! I had a big horizontal crack on my concrete retaining wall and was having no luck repairing it with regular concrete mix. It wouldn't stick, it would just flop out. Plus, I don't know if my mixing skills are poor but even after a couple of days I could pick up the leftovers and break the chucks with my bare hands. (I tried several mix ratios, no luck with any of them.) I read about this mortar mix and decided to try it in an un-repaired section. Wow, did it work wonders! No problem sticking in place and strong as an ox when it dried. I took a piece of rebar and chiseled out the other stuff I'd been using (not hard to do, it just flaked right out) and redid the repair with this. How I wish I hadn't wasted three days of experimentation with the other stuff. As others have said, this mix sets *fast*-- you have about 10 minutes of workable use before you're dealing with a brick in your bucket, so make sure to mix in small quantities. But it works great if you take that into account. January 1, 2015
