Je ne sais pas si c’est ce produit isy fin ou le standard ou même le vernis mais au bout d’une semaine premier choc premier trou. Assez déçu de la dureté du produit surtout au prix que ça m’a coûté. Je ne le recommanderais pas et ne l’appliquerais pas non plus chez mes clients

Girard M. published the 11/10/2020 following an order made on 07/09/2020


Excellent vernis, je n ai pas l habitude de laisser des commentaires mais ce vernis à un rendement exceptionnel ! Après avoir essayé des vernis décevant parfois assez cher dans de grandes enseignes de bricolage, là c est incomparable, le vernis forme une protection résistante sur le support, je l ai utilisé pour un évier réalisé en beton et pour un receveur de douche également, bien respecter les doses, application relativement simple au rouleau. Je me sers de l évier depuis plus d un mois, résistance aux chocs impressionnante, et béton totalement imperméabilisé, de plus la quantitée permet de faire plus que ce qui est indiqué. Quand la qualité est là il faut vraiment le souligner. Je ne connaissais pas le bi-composant avant, je n utiliserais plus d autre vernis, ras le bol de se faire avoir avec du "vernis deco" qui ne fait pas le job, enfin la qualité, le prix me paraissait cher au début, d autant plus qu il faut combiner avec le bouche pores, mais franchement au vu du résultat, ça vaut vraiment le coup ! Merci.

Bien, mais il faut bien réaliser la finition en dessous...parce que le vernis accentue les défaut.
