Tenax Mastidek Fast Outdoor Cartridge Adhesive – 215 mL, 2:1, Dark Grey, for Dekton
Tenax Mastidek Fast Outdoor Cartridge Adhesive – 215 mL, 2:1, Dark Grey, for Dekton
The Tenax Mastidek Fast Outdoor Cartridge Adhesive in Dark Grey is a 215 mL pre-dosed 2:1 two-component cartridge adhesive formulated for bonding Cosentino Dekton, colored to match Dekton's dark grey surfaces and approved by Cosentino for indoor and outdoor seams, miters and laminations.
It is a Dekton adhesive and its value is the color match and the outdoor-rated bond on that ultra-compact surface. For granite, quartz and marble use a general stone adhesive such as Superior Gold Evolution, and note that Mastidek needs Tenax's 2:1 cartridge gun (M200XMR, not stocked here) with a threaded static mixing nozzle; a 10:1 or 1:1 gun will not fit.

What This Is Not For
Not a general stone adhesive: it is formulated and color-matched for Dekton and needs a 2:1 gun. For granite, quartz and marble use Superior Gold Evolution cartridges; for a 10:1 or 1:1 cartridge system use the matching gun.
Who Is This For?
Fabricators and installers seaming, mitering and laminating Dekton, especially outdoor kitchens and facades where the joint must match a dark grey Dekton color and hold up to weather.
Frequently Asked Questions
Which Dekton colors does Dark Grey match?
Tenax names the Mastidek colors after the Dekton palette they suit; Dark Grey is the dark grey shade. Tenax publishes a Mastidek color-match tool for pairing a specific Dekton color to a cartridge, so check it before ordering for a particular slab.
What gun do I need?
A 2:1 dual-cartridge gun. Tenax specifies its M200XMR cartridge gun with a threaded Mastidek mixing nozzle, which is discarded after each use.
How soon can I polish the seam?
Tenax publishes 45 to 60 minutes at 77°F before cutting and polishing; the adhesive gels in 3 to 5 minutes and pieces can be moved after about 15 minutes.
Can I use it in cold weather?
It cures at temperatures down to 34°F (+1°C) and does not harden below that. Cure slows as the temperature drops.
Is it for outdoor use?
Yes. Mastidek Fast Outdoor is rated for exterior bonding and is approved by Cosentino for Dekton.
Will it work on granite or quartz?
It is formulated and colored for Dekton. For natural stone and quartz, a general stone adhesive such as Superior Gold Evolution is the right choice.
