Sashco 15020 Grout Caulking, Mortar and Stucco Repair Sealant, 10.5 Ounce Tube, Ironstone/Gray

This stuff is amazing. I’ve used it in the kitchen, outside to seal up what should’ve been concrete and grout. My only mistake when ordering was not ordering enough. Once you get a tube, you’re going to find a lot of uses for it.

Used this to fix cracks in my stucco before painting. Works great.

This turned out to be Ironstone. The texture looks good but it is to brown to match my mortar. I will buy a tube of grey from another supplier (Amazon doesn’t have single tubes of grey.) and mix it to get the right color. I hope.

I am quite pleased with the Sashco 15030 Mortar Grout. It sticks, it is the right color and it has a mortar like texture. My only gripe is that it is very expensive at 10.5 ounces. It would cost a fortune to repair one wall. Compared to other types of caulking, it is over-priced.

Great matching mortar.

Needed something to make a repair to a door's floor weather seal. It was on concrete with small tiles up to it. Needed it to look somewhat close to the grout that was originally used. Did not want to mess with making up a batch of grout. This product worked well. Repair looks pretty good from thirty feet and 30 mph. :-)

Waste of money. Product looked promising but when opened it would not dispense. It was dried out in tube.

I just followed the instructions that I found on YouTube for patching cracks in stucco and it did the trick!
