Hermetic shield is a finishing conditioner applied after polishing the concrete surface. It introduced additional Colloidal Silica to the slab, along with a thin, clear polymer layer that gives extra protection to the concrete surface. It brings out the colour in integrally pigmented, stained or dyed concrete.
Hermetic shield provides extra protection against accidental staining from spills. It is particularly useful against mild acids (e.g., environments where food is handled or served).
- Use 1 part Hermetic shield to 1 part potable water
- Apply with pump sprayer at a maximum rate of 2000 ft²/ga and work in with a micro-fiber mop
- After two coats, use high speed burnishing to increase the shine
