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.

Sets hard
Easy to apply, with cartridge gun. Has a fairly course finish which dries rock hard, so ensure you smooth it out before it fully sets!

Easy to use and does a good job
Got this to fill some holes in mortar and brickwork where we were having a change around on the front of the house, mailbox etc. This product is very easy to use and fills well. Good colour match for my mortar and for the brick work I just drilled the holes a little and collected the brick dust in a container and then dabbed the dust on the cement once the holes were filled to blend into the brickwork. Dried down nicely, you'd never notice that there were holes there before. Good stuff.

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.

Mortar cement
Noticed a crack on one of my walls and used this to fill it. I tried other cement repairs before but to be honest they were very difficult to squeeze out the tube. This product squeezed out easily and it it sealed up the crack beautifully. I will definitely buy this again

Rubbish, came out the tube dry and powdery, sticks to nothing, totally worthless.
Got this to stick some loose bricks together and repair some loose coping stones. Should have just used regular cement, and saved some money. Firstly it has a best before date on the tube, which showed it still had 3 months left. But when you squeeze it out the tube, it's powdery and dry, and actually just rolled off the bricks onto the ground. Had to use a spatula to scoop it up and reapply it, right from the beginning I was unimpressed. Anyway, two days later it has dried, but nothing has stuck, the bricks just pull apart and the "cement" just brushes off. Complete waste of money, 2 tubes cost about £12 and only covered a few bricks and 2 coping stones. For much the same price you can mix up a whole cement mixer of mortar, your not even paying for the extra convenience, because it just doesn't work.

Cement Grey 310ml Ready Mixed Repair Mortar Cartridge
Very pleased with my purchase. Item is grey in colour and did not match Mortar in brickwork.But I still found it useful filling a crack down wall.

Gut.
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.

un bon produit mais difficile a extruder
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.

ciment
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

Schnell und praktisch zu verarbeiten
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.
