Adhesives Technology Convergent Pentra-Sil (C&N) 5 Gallon Pail
Pentra-Sil (C&N) is the lithium clean-and-neutralize first step for concrete with efflorescence, sweating, or high alkalinity.
- Infuses lithium ions to stabilize sodium and potassium at the surface
- Target rinse pH of 5 to 6 on the treated slab
- Follow with Pentra-Sil (AC) when sweating or salts persist

Adhesives Technology Pentra-Sil (C&N) Clean and Neutralizer, 5 Gallon Pail
Pentra-Sil (C&N) from Adhesives Technology is a lithium clean-and-neutralize treatment for concrete with surface sweating, efflorescence, or other alkalinity problems. It infuses lithium ions to stabilize the slab and is the first step of a two-part system, followed by Pentra-Sil (AC) on severe floors. Crews spray, scrub, and rinse with an auto-scrubber, then proceed when the surface is dry.
Key Features
- Cleans and neutralizes sweating or blooming concrete
- Infuses lithium ions to stabilize slab alkalinity
- First step before Pentra-Sil (AC) on severe floors
- Removes fine dust that can cut shine
- Spray, scrub, and rinse; no film to peel
- Not for plastic concrete or resin-based terrazzo
Applications
- Sweating slabs and efflorescence cleanup
- Floors with sodium, potassium, or other alkalinity problems
- First step of a two-part (C&N) then (AC) treatment
- Interior slabs where conventional cleaners are not enough

Frequently Asked Questions
Is Pentra-Sil (C&N) the first step on a sweating or efflorescing slab?
Yes. Pentra-Sil (C&N) is the clean-and-neutralize first step. It infuses lithium ions that neutralize excess sodium, potassium, and other alkalinity so alkaline salts and sweating are reduced. Pentra-Sil (AC) follows on more extreme floors.
What rinse pH should a crew see after Pentra-Sil (C&N)?
The Pentra-Sil (C&N) sheet lists pH 5 to 6. That is the clean-and-neutralize target, not a coating pH. If the slab is still sweating or blooming after C&N, the next lithium step is Pentra-Sil (AC).
Does Pentra-Sil (C&N) remove dust that cuts shine?
Yes. Pentra-Sil (C&N) is called out for removing fine particles and dust that can reduce shine, while it stabilizes the surface. Grocery, hangar, and warehouse floors are typical interiors that see that alkalinity plus dust problem.
Can Pentra-Sil (C&N) go on asphalt or painted surfaces?
No. Pentra-Sil (C&N) is for cementitious concrete, not asphalt, non-cement surfaces, or painted slabs. Keep it on structurally sound concrete that is actually showing alkalinity, sweating, or efflorescence.
Where is Pentra-Sil (C&N) typically used?
Pentra-Sil (C&N) shows up in grocery stores, parking garages, hangars, loading docks, food plants, and warehouses. Those interiors collect alkali salts and dust. C&N is the first lithium step, not a polish densifier.
Should Pentra-Sil (C&N) be followed by Pentra-Sil (AC) on a severe floor?
Yes, when symptoms are extreme. The sheet recommends a full treatment of Pentra-Sil (C&N) followed by Pentra-Sil (AC). C&N cleans and neutralizes. AC then holds alkalinity and vapor drive down.
