Adhesives Technology Convergent Pentra-Sil (C&N) 5 Gallon Pail
Cleans and neutralizes concrete surfaces that suffer from efflorescence, surface sweating, and other alkalinity problems by infusing lithium ions into the substrate. These ions neutralize the effect of excessive sodium, potassium and other alkalinity, reducing the formation of alkaline salts and sweating.
- VOC Compliant
- Stabilizes concrete surfaces
- Prevents efflorescence

Convergent Pentra-Sil (C&N) Clean and Neutralize Treatment 5 Gallon
Pentra-Sil (C&N) is a lithium-based clean-and-neutralize treatment used as the first step for severe sweating slabs and efflorescence problems. It prepares the surface for subsequent densification with Pentra-Sil (AC) or other densifiers.
Key Features
- Cleans and neutralizes high-pH and contaminated concrete surfaces.
- Prepares severe sweating or efflorescing slabs for densifier application.
- Lithium-based chemistry compatible with the Pentra-Sil system.
- Helps reduce alkaline salt migration.
- VOC compliant.
Applications
- First step in two-step treatment of severe slab sweating and efflorescence.
- Preparation of high-pH concrete before coatings or adhesives.
- Concrete floors with persistent alkalinity-related problems.
- Use prior to Pentra-Sil (AC) densification.

Frequently Asked Questions
When is the two-step C&N + AC system recommended?
For severe or persistent sweating slabs and heavy efflorescence. Apply (C&N) first to clean and neutralize, then (AC) to densify and provide lasting alkalinity control.
Can (C&N) be used alone?
It is primarily a pre-treatment. For lasting densification and protection, follow with Pentra-Sil (AC) or another densifier.
What problems does it address?
High surface pH, slab sweating, and migration of alkaline salts that cause efflorescence and coating failures.
Is it compatible with other Pentra products?
Yes. It is designed as the first step in the Convergent alkalinity-control system that includes Pentra-Sil (AC).
