Adhesives Technology Convergent Pentra-Sil (AC) 5 Gallon Pail
Pentra-Sil (AC) is a lithium alkalinity-control treatment for sweating, efflorescing, or high-pH concrete, used after Pentra-Sil (C&N) on severe floors.
- Neutralizes surface alkalinity and cuts salt vapor drive
- Densifies and hardens for better abrasion resistance
- Use after Pentra-Sil (C&N) on more extreme floors

Adhesives Technology Pentra-Sil (AC) Alkalinity Control Treatment, 5 Gallon Pail
Pentra-Sil (AC) from Adhesives Technology is a lithium alkalinity-control treatment for sweating, efflorescing, or high-pH concrete. It reduces vapor drive that carries alkaline salts to the surface and densifies the slab for better abrasion resistance. Typical work is existing interiors after sodium or potassium silicate densifiers. Severe floors start with Pentra-Sil (C&N), then (AC).
Key Features
- Built for sweating, efflorescing, or high-pH slabs
- Neutralizes surface alkalinity and cuts vapor drive of salts
- Densifies and hardens for better abrasion resistance
- Penetrating lithium treatment; no film to peel
- Spray, work in with a scrubber or broom, then rinse
- Use after Pentra-Sil (C&N) on more extreme floors
Applications
- Sweating or efflorescing interior concrete
- High-pH surfaces after sodium or potassium silicate densifiers
- Warehouses, grocery, and other occupied slabs with salt bloom
- Second step after Pentra-Sil (C&N) on severe cases

Frequently Asked Questions
When should Pentra-Sil (AC) follow Pentra-Sil (C&N)?
On severe sweating or efflorescence, the sheet calls for Pentra-Sil (C&N) first, then Pentra-Sil (AC). C&N is the clean-and-neutralize first step. AC is the alkalinity-control treatment that follows on those extreme floors.
Does Pentra-Sil (AC) reduce slab sweating?
Yes. Pentra-Sil (AC) is built for sweating, efflorescing, or high-pH surfaces. It neutralizes the surface and reduces the vapor drive that carries alkaline salts to the top of the slab.
Why would a sodium-silicate floor still sweat after densifying?
High pH at the surface is often made worse by sodium or potassium silicate densifiers. That pH imbalance draws moisture. Pentra-Sil (AC) permeates the surface to mitigate that imbalance so alkaline salts are less likely to form efflorescence.
Does Pentra-Sil (AC) also harden the slab?
Yes. Nano-Lithium in Pentra-Sil (AC) densifies and hardens the surface and increases abrasion resistance while it is controlling alkalinity. It is still an alkalinity-control primer, not a polish densifier.
Is Pentra-Sil (AC) a film-forming coating?
No. Pentra-Sil (AC) is a penetrating lithium treatment with no film to peel. Sweating and salt drive are handled inside the surface, which is why AC is used on interior slabs that keep pulling alkali to the top.
Can Pentra-Sil (AC) be used without a C&N step on a milder floor?
Pentra-Sil (AC) is the alkalinity-control treatment for sweating or high-pH slabs. The C&N-then-AC sequence is specified for more extreme symptoms. On a milder high-pH floor, AC still addresses alkalinity; reach for C&N first when the slab is already blooming salts.
