Rated 5 out of 5 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 out of 5 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 out of 5 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 out of 5 by UNBELIEVABLE!!! Hands Down, awsome!!!!!! This stuff is unbelievable....Totally amzing!!!! Use in small portions, Sets very fast, great for vertical apps!!!!!! September 18, 2014
Rated 5 out of 5 by Follow directions and it works great! I used this stuff to fix my outdoor foundation that had some bad scaling. I used the additive that let's you work longer with the mix which was sold right next to the bags at Home Depot. I had about 35 minutes to work with each 55 pound bag (it was about 80 outside) which was more than enough time just make sure you are prepared to work as soon as you mix it. September 10, 2014
