Good but runs out quickly
This is easy to use and saves time trying to get right mixture doing it yourself. Drawback we had to use rechargeable gun as thick. Biggest issue is it doesn’t cover much area. I was doing between my slabs and one tube only did two and a half so beware how much you need.

Good idea but tricky to use
The idea is good and once it dries is solid and good! But application is a bit of a pain, not cheap either

Easy to use and solid quality, but colour match is critical
I bought this SX Trade Strength mortar repair to do some repointing work around my brick house. Application was easy and the mortar itself feels good quality once applied. It sets well and is ideal for small repair jobs where you don’t want to mix up a full batch of mortar. The main thing to be aware of is the colour. It’s quite a light grey, and in my case it didn’t match the existing mortar on my house. The repair stands out more than I’d like, and I’ll need to find a darker option in the future to blend it in better. Overall, the quality of the product itself emphasizes reliability, but matching the existing mortar colour is essential for cosmetic repairs. Good for structural or functional fixes, but be careful if appearance matters.

Wouldn’t buy again
I was disappointed with this - it did not come out of the gun easily (in fact, it broke the gun, I had to apply so much pressure). It also didn’t stay where I applied it, it sort of dragged behind the tube as I moved along, meaning I had to use my finger to keep it where I wanted it. It’s a nice idea and would have been great if it had worked but I’m grateful I only bought two tubes as it was ultimately rubbish and a waste of money.

Good price and product for small repairs.
I bought two tubes, it was easy to use although it was a little hard to squeeze out at first. Before starting you need to ensure any loose material is cleared out of the gaps to be filled otherwise the filler can fall out. The colour is a light grey which blended well with my cement which is around 30yrs old, I’m happy with the results. Like the Bruce Willis film it Dries Hard. I know!
