Perma-Chink is the brand's original chinking compound, developed specifically to seal the gaps between logs and timbers in solid wood homes.

Its textured appearance replicates the look of traditional mortar chinking, while offering the performance of a modern acrylic sealant. Unlike a rigid material, Perma-Chink remains flexible and accommodates the natural movements of wood due to temperature and humidity variations.

It forms a durable barrier against air and water infiltration, while giving facades the characteristic aesthetic of traditional log homes.

Perma-Chink can be used outdoors as well as indoors and is particularly suitable for wide and intentionally visible joints.

Available in our shop in 11 oz (325 ml) and 30 oz (887 ml) cartridges.

  • Le support doit être propre, sec et exempt d'huile, de cire ou de toute substance susceptible de nuire à l'adhérence.
  • Installer un fond de joint (Backer Rod) ou un matériau de support adapté dans l'espace à traiter. Le mastic doit adhérer aux deux côtés du joint, mais pas au fond. 
  • Insérer la cartouche de 11 oz ou 30 oz dans un pistolet manuel ou électrique adapté.
  • Couper la canule selon la largeur du joint souhaitée.
  • Appliquer Perma-Chink de manière régulière sur le fond de joint. L'épaisseur recommandée est d'environ 5/16" à 3/8" (8 à 10 mm) et ne doit pas dépasser 1/2" (13 mm). 
  • Vaporiser légèrement la surface du mastic avec de l'eau immédiatement après l'application afin de faciliter le lissage.
  • Lisser le joint à l'aide d'une spatule plate en exerçant une légère pression afin d'obtenir une finition régulière et d'assurer une bonne adhérence sur les bords. 
  • Éviter l'application en plein soleil ou sur un bois très chaud.
  • Nettoyer les outils à l'eau et au savon immédiatement après utilisation.
