Needed it fast.
Needed this specific product for a client task. As always the main criteria was getting the item quick as this was a urgent task. Delivery was quick and well packaged. The product worked well but as this product was a requirement by the customer I don't think it's fair to compare it to other products. It has remained flexible and provided a weatherproof seal on the component.

Resistenza superiore e qualitĂ da vecchia formulazione
Resiste a sole, pioggia e agenti chimici in misura superiore al già valido Sikaflex 11 FC. Sarà forse perché contenuto in una cartuccia metallica, ma mi ha ricordato l’11 nella sua vecchia formulazione. Ottima adesione su metallo, legno, PVC, vetro, ceramica e superfici murarie: un sigillante versatile e molto affidabile.

Le Sika ne déçoit jamais ! Un indispensable pour l'étanchéité
Il n'est plus la peine de faire la publicité de Sika ! Cette marque est presque indispensable sur bon nombre de chantiers, qu'ils soient professionnels ou amateurs, et ce produit ne fait pas exception à la règle. ✅ Points Forts : • Réputation Confirmée : On achète Sika, on achète la tranquillité. La qualité est toujours au rendez-vous. • Facilité d'Application : Le produit s'extrude et se lisse très facilement (avec les outils adéquats, bien sûr !). Il a une bonne consistance, sans couler. • Double Rôle Parfait : Il colle bien et fait parfaitement son rôle de joint d'étanchéité (intempéries, humidité, etc.). • Adhérence : J'ai obtenu une très bonne adhérence sur mes supports (vous pouvez ajouter les supports si vous voulez, ex: bois, métal, béton). C'est un produit fiable que je valide sans hésitation. Si vous cherchez un colle-mastic polyvalent et durable, vous l'avez trouvé. Je recommande ce produit à 100% !
