SpecHard Water-Based Siliconate Sealer/Densifier

SpecHard-Intraseal is a water-based silicate/siliconate sealer and densifier that hardens and beautifies concrete floors under pedestrian and vehicle traffic

SpecHard-Intraseal is a colorless, proprietary blend that penetrates concrete to seal, densify, and harden it, extending its lifespan and reducing maintenance. It's environmentally friendly, VOC compliant, and odorless, resisting dusting for years with a low sheen finish.

Key Features & Benefits

• Strengthens and densifies concrete, improving abrasion and compressive strength
• Reduces porosity, resisting water, oil, and chemical penetration
• Dustproofs surfaces and helps control hairline cracks
• VOC compliant, non-yellowing
• Meets ACI 302 Class 1-5 concrete floors and Class 9 super flat floor standards; USDA compliant
• Compatible with SpecChem SpecTilt bond breakers

Application Instructions

• New concrete should cure 7 days or longer before application; SpecChem E-Cure is the preferred curing method
• Membrane-forming curing compounds must be removed before applying SpecHard-Intraseal
• Apply when temperatures are above 40°F and below 100°F
• Not a substitute for a curing compound — green concrete has too much water for proper penetration
• If applied early (after 3 days at 70°F+), apply a "spiff coat" at 28 days for best long-term performance

Packaging

Available in 5-gallon pails.
