Why installers choose Fix ALL™ High Tack
High initial grab reduces the need for temporary bracing.
Fast curing and high final shear strength on most substrates — often without a primer.
Stays elastic after cure; accommodates movement and vibration.
Porous and non-porous: concrete, masonry, wood, MDF, metals (aluminum, steel), ceramic, natural stone, glass, many plastics, and painted surfaces. Works on wet or humid surfaces.
How to use
Cut nozzle to desired bead size (e.g., 1/4"–3/8") and apply with a standard caulk gun.
Place beads or dots on the substrate; press parts together firmly. Brace if needed for heavier items.
Tool within a few minutes; allow to cure (skin time and cure rate depend on temperature/humidity).
Cartridge size: 290–310 ml (typical). Coverage varies by bead size and substrate.
Color: White
Pro tips: For best results, clean and de-dust substrates. Test adhesion on sensitive or coated materials. Paintable with most water-based paints after skin formation.
