Pentra-Sil (HD)
Pentra-Sil (HD) is a Convergent high-solids Nano-Lithium densifier in a 5 gallon pail for existing concrete and polishing work. It penetrates and reacts in the slab to raise abrasion and stain resistance, cut dusting, and add a slight sheen without a peelable film. Keep the surface wet approximately 20 minutes and apply above 40 F. Broom-finished coverage is approximately 200 to 400 sq ft per gallon.

Frequently Asked Questions
What work is Pentra-Sil (HD) for?
Existing concrete densifying and dustproofing, plus polishing passes that need more abrasion and stain resistance without a peelable film. Typical slabs include warehouses, retail floors, hangars, loading docks, and industrial plants.
What pail size is Pentra-Sil (HD) on this page?
A 5 gallon pail, MPN CCT-050-5. The chemistry is the same high-solids Nano-Lithium densifier as the drum. Total solids are 16.0%, pH is 11 to 12, and VOC is under 50 g/L.
What broom-finished coverage does Pentra-Sil (HD) have?
Approximately 200 to 400 sq ft per gallon on broom-finished concrete. Machine-troweled floors plan approximately 550 to 750 sq ft per gallon. Porosity and jobsite conditions change the rate.
What rinse step does Pentra-Sil (HD) need on machine-troweled concrete?
After approximately 20 to 30 minutes of dwell time on machine-troweled, dyed, acid-stained, or integrally colored concrete, scrub with water and pick up the excess. On broom-finished work, keep wet approximately 20 minutes and broom out puddles as it dries in.
What temperature does Pentra-Sil (HD) 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.
What limitations does Pentra-Sil (HD) have?
It will not bridge cracks or salvage honeycombed or structurally unsound concrete. It is not for asphalt, non-cement, or painted surfaces. Paint and coatings may go over the densified slab after it dries.
