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.

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% !
