Pentra-Sil (H)
Pentra-Sil (H) is a Convergent Nano-Lithium densifier in a 55 gallon drum for freshly placed concrete, tilt-up slabs, and existing cementitious surfaces. One coat sprays on wet, newly finished concrete, needs no rinse, and leaves no peelable film. Tilt-up bond-breakers go over the treated slab. Keep wet approximately 20 minutes and apply above 40 F. Machine-troweled coverage is approximately 450 to 650 sq ft per gallon.

Frequently Asked Questions
What slabs is Pentra-Sil (H) used on?
Freshly placed concrete, tilt-up construction slabs, existing concrete, and cementitious overlays. It is the time-of-placement Nano-Lithium densifier: one coat, no rinse, no peelable film. Typical work includes warehouses, hangars, loading docks, and industrial floors.
What drum size is Pentra-Sil (H) on this page?
A 55 gallon drum, MPN CCT-075-55. Total solids are 9%, pH is 11 to 12, and VOC is under 50 g/L. The liquid is opaque and dries clear.
What coverage does Pentra-Sil (H) have?
Machine-troweled floors plan approximately 450 to 650 sq ft per gallon. Coverage varies with porosity and jobsite conditions. Keep the surface wet with product for approximately 20 minutes.
What timing does Pentra-Sil (H) have on new machine-troweled concrete?
It may be applied immediately after finishing, immediately after joints are cut and cleaned, or anytime after. Keep wet approximately 20 minutes and broom out puddles as it dries in. The surface is ready when dry.
What bond-breaker timing does Pentra-Sil (H) have?
Tilt-up bond-breakers go over the treated slab. Curing compounds can also go over once the densifier is dry, and those curing compounds are easier to scrub off later.
What temperature does Pentra-Sil (H) need?
Apply only when temperatures stay above 40 F for at least 2 hours after placement. On hot slabs above 90 F, cool and dry the surface first so the densifier does not flash-dry before it penetrates.
