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 👌

Great product, but not suitable for a plastic mastic gun
I have what I thought was a pretty standard mastic gun - it's black plastic with metal springs etc. It was not strong enough to push the 'mortar' from the tube. It came out so SLOWLY it would have taken for ever to repoint the 2m run I had to do. I ended up cutting open the tube and pointing in the traditional way with a small trowel. Great product, great bond and adhesion just not very easy to use

Poor quality product, does not come out of the tube easily. Very wet and grainy, takes forever to dry. Not fit for purpose

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.
