Adhesives Technology SlabArmor Starter Colloidal Silica Curing Aid, 5 Gallon Pail
SlabArmor Starter from Adhesives Technology is a colloidal silica curing and finishing aid for new concrete, including low-carbon Type IL mixes. The hydrophilic liquid holds bleed water in the capillaries during placement, which helps reduce shrinkage, micro-cracks, and tool wear while extending working time. Three coats at about 1,200 ft² per gallon go down during troweling; it is also used as a densifier in polishing.
Key Features
- Colloidal silica curing and finishing aid for fresh slabs
- Holds bleed water in the capillaries to cut shrinkage cracking
- Extends working time and can reduce tool wear
- Non-film forming; user friendly and non-whitening
- Densifies for polish work and helps cut diamond wear
- Useful on thirsty Type IL low-carbon mixes
Applications
- Placement and power-trowel finishing of new concrete
- Hot, windy, or dry days when bleed water is leaving the slab
- Type IL and other low-carbon mixes that finish dry
- Impregnating hardener during grind-and-polish of concrete or terrazzo

Frequently Asked Questions
What does SlabArmor Starter do during finishing of new concrete?
SlabArmor Starter is a colloidal-silica curing and finishing aid. Its hydrophilic property holds bleed water in the capillaries during curing, which reduces shrinkage and micro-cracks and leaves a denser, more workable surface.
Is SlabArmor Starter a film-forming cure?
No. SlabArmor Starter is a non-film-forming curing aid. It does not leave a membrane to strip later. That is why it is used on industrial, commercial, and decorative slabs that will be hardened and polished.
Can SlabArmor Starter be used as a polish densifier during grinding?
Yes. SlabArmor Starter can also be used as an impregnating hardener/densifier during grind-and-polish of concrete or terrazzo. Nanoparticle silica makes re-profiling easier and reduces wear on diamond abrasives.
Does SlabArmor Starter reduce alkalinity and efflorescence?
Yes. SlabArmor Starter is listed for reducing alkalinity and efflorescence while it deepens clarity and heightens reflectivity in a polish sequence. Those are finish-floor results of the colloidal-silica Starter, not a membrane cure.
Is SlabArmor Starter GreenGuard Gold listed?
SlabArmor Starter carries UL 2818 GreenGuard Gold certification for low chemical emissions. Occupied interiors that want a non-film-forming curing aid keep that listing with the pour.
Does SlabArmor Starter whiten the slab?
SlabArmor Starter is described as user friendly and non-whitening. Non-film-forming chemistry is why it is used on decorative and industrial floors that cannot show a white membrane residue.
