Very happy with how well it works, but make sure you protect the surrounding tiles properly to avoid marks during application.

Très pratique !
Très satisfait de l’efficacité, mais prévoir de bien protéger les carrelages autour pour éviter les traces lors de l’application.
Le produit fait bien son travail. Il rend les joints résistants aux taches sans modifier leur couleur.
Mes joints restent comme neufs, même en cuisine
