Commande et livraison, RAS. Les produits arrivent en bon état, tout voir plus
Commande et livraison, RAS. Les produits arrivent en bon état, tout est relativement clair dans les notices. Les produits sont compatibles avec du béton cellulaire (poreux), la quantité du primaire d'accroche est vraiment trop juste. Les produits à travailler sont très bons dans l'ensemble. Le seul problème selon moi, ce sont dans tous les produits (hors primaire) il y a comme des grumeaux, une sorte de peau. Malgré tout, nous sommes contents du résultat.
