Ease of use
I purchased this to repair a garden wall where top bricks are coming loose , there is mortar missing and needed filling, it is a very light grey but blends in well . I was surprised by how easy it is to use , and got a really good finish, it hasn’t set and will probably take a few days as it’s not very warm but no different to mortar but is so much easier. The applicator supplied works really well too 👌

Does what it’s meant to do
It was abit hard at first to get it all moving with the gun. But after it was quite good. I can’t complain at all, it’s done what I’ve needed it to do. It’s very soft but I would recommend this product. I’ve just started getting into DIY and I think this is good for the price and for what I needed it for.

Top Tips Good for Very Small Jobs
This product is only suitable for very small & time consuming repairs where it is not practical or economic to use in larger volumes. Top Tip 1 If you need more than 250ml of mortar buy a larger ready mix tub or mix your own mortar pared down by volume. Warning If you are working precisely using your cartridge gun this product will test your strength and patience. It is difficult to get it out of the tube. Top Tip 2 I recommend juggling or rolling the cartridge vigourisly before inserting the cartidge in the gun. This activates the product and makes squeezing easier and less difficult. Top Tip 3 If you want around half a cartidge volume of mortar at a single time I find it much easier to ditch the gun. You will find cutting the cartridge longways with a knife much simpler and easier. You can then use each half cartridge very quickly and much more easily. Each half cartridge is a very useful size to hold and this is good for smaller repointing jobs where only a very limited repair is required especially at height. Hope this helps you to decide whether this is the right product for you.

Great Stuff!
This is great...mortar in a tube! Great for small bits of pointing etc., the size of the original cut nozzle is just the right width for the gaps between the bricks. Fantastic that I didn't have to get big bags of sand and cement that I would have had no further use of. It comes easily out of the tube, all the way to the end and it looks good, it's a decent match in colour to the existing mortar so it doesn't stand out too much. I've got no idea on it's durability, ask me in a few years but at only £5 a tube I won't mind if I have to replace it when I repaint the door lintel in another 5-7 years time. Only downsides are that it could be in a slightly bigger tube...once I got started I kept finding other little cracks that needed filling...and there's no kind of cap that you can stick on the end to prevent it curing, if you don't happen to finish the tube. Overall, I'd definitely recommend.

Poor product. Has not dried over several days.
Absolutely rubbish. Several days in and still wet. Does not dry quickly and now have to spend time cleaning it out to repair what should have been a simple task. I do not recommend this product.

Express cement
Repairability: Easy to use for small repair jobs around slabs, just have a trowel handy when flushing the cement off. Speed: Repair jobs done with ease and dries quickly. Why did you choose this product over others?: Price!

Needs a heavy gun ......
Not tried this method before, worked well..... except you need a sturdy gun, broke my cheaper guns (twice) before getting a heavier gauge metal frame one.

Genau was man erwartet allerdings sind die Kartuschen nicht so stabil und es verbleibt ein Rest wenn man sie nicht öffnet der als Schwund einkalkuliert sein sollte. Dennoch recht komfortabel.

le produit est très bien: une sorte de mousse de ciment qui s'applique facilement et semble très solide une fois sèche. J'ai colmaté des petites fissures et refait des joints sans difficulté. Le résultat une fois sec est très bien. Le problème vient de l'extrusion de la cartouche: facile au départ, difficile arrivé aux deux tiers et impossible pour le dernier quart. Obligé de couper la cartouche pour utiliser le produit restant ! Cet inconvénient était mentionné dans plusieurs commentaires, c'est bien réel.

a conseiller pour boucher des fissures de mur refaire des marches d'escalier..... mais il faut absolument "un injecteur" sinon il faut "briser le recipient"(ce que j'ai du faire

Es wurde ein tiefes Loch ca 30mm im Durchmesser, geschlossen. Nach Stark-regen wurde durch das Loch im Boden/Garage Wasser herausgedrückt. Ist nun abgedichtet. Die ganze Kartusche passte hinein.
