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 donโt want to mix up a full batch of mortar. The main thing to be aware of is the colour. Itโs quite a light grey, and in my case it didnโt match the existing mortar on my house. The repair stands out more than Iโd like, and Iโll 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.

Decent enough
Good enough although it could maybe do with a little more moisture through it in order to help stick to a dry surface. Easily rectified and other than that it does its job well enough.

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, Iโm happy with the results. Like the Bruce Willis film it Dries Hard. I know!

Does what I cannot - great quick fix and still going strong.
I'm a competent DIYer but building work is something I rarely do. When it comes to brickwork I do it so infrequently that I have never got good at it. Reeccently I had need to replace an old rotten single pane wooden window with a new uPVC one. It was a struggle but looked OK but my attempt at mixing my own mortar and repairing the brickwork was a failure. The next day a small child could with only a sneezs have undone what I had done. So I bought some of this stuff - easy to use just like any other gunk you might have in your cartridge gun. Various colours available and it did the job of sizing the brickwork around the new window and beneath the cill in no time. The brickwork is still solid. I was fairly sure the stuff wouldn't keep so I used the little bit that was left fixing the back step. It's not cheap stuff but if you have had a bit of bother and need it to work this stuff is perfect to bridge the gap between skill and need.

Good seal but a nightmare to squeeze out.
It seems to set quite nice and is basically like mortar but as its so firm and rigid in the tube you need to be like popeye to squeeze it out. Tube split eventually.

Very difficult to dispense, required so much pressure that it bent my caulking gun!
Impossible to dispense, broke my caulking gun! Applied at room temperature, still required so much pressure that it broke my caulking gun (which I have had for many years and was very sturdy)

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
