IntraHard

INTRAHARD is a premium blended silicate sealer, densifier, and hardener for concrete surfaces. Our proprietary silicate blend reacts within the concrete to form calcium silicate hydrate in the concrete pores.

INTRAHARD’s silicate blend provides a breathable surface while reducing porosity, dusting, and water permeability, and increasing abrasion resistance.

INTRAHARD delivers complete densification, ideal for Type 1L cement concrete mix designs.

Cost-Effective Application – One-step, low-pressure spray application on broom or hard-troweled finishes

Architectural Finishes – Does not contribute to Alkali Surface Reaction (ASR)

Enhanced Performance – Reduces dusting, porosity, and water permeability

Superior Durability – Improves abrasion resistance, light reflectance, stain resistance, and gloss

Versatile Use – Breathable formula suitable for interior and exterior applications

Fast Curing – Ready for traffic in one hour for most floors

Flexible Application – Apply on new or existing concrete

Environmentally Responsible – Economically efficient sealer solution

Low Maintenance – Single application with minimal maintenance requirements

Industry Approved – USDA Accepted. Recommended for ACI 302, Class 1 through 5 concrete floors, and Class 9 super flat floors

Application

Always follow the Technical Data Sheet instructions and Safety Data Sheet (SDS) safety information. INTRAHARD may be applied to concrete that will be polished or burnished. Always apply INTRAHARD to a clean surface free of cures, bond breakers, oil, dirt, grease, or debris. When necessary, clean concrete surfaces with SpecChem Orange Peel or Berry Clean and neutralize with a neutral pH detergent. Thoroughly flush with water.

APPLICATION FOR FRESHLY PLACED CONCRETE

After final finishing, apply INTRAHARD using a quality low-pressure sprayer with a fan tip. Uniformly spread INTRAHARD with a soft broom or microfiber applicator to thoroughly coat the concrete, eliminating any puddles or excess. Apply enough material to keep the surface wet for approximately 15 minutes. Apply additional INTRAHARD to porous areas until rejection occurs.

Remove any excess INTRAHARD from the surface with a squeegee, power sweeper, or floor scrubbing machine.

A compatible ASTM C309 curing compound such as SpecChem “SpecRez” or “E Cure” may be applied to finalize the curing process. After the concrete has thoroughly cured, a floor scrubber equipped with a nylo-grit or similar abrasive cleaning pad will remove any residual construction debris and curing compound, and further enhance the INTRAHARD surface shine.

APPLICATION AS PRE-SEAL DENSIFIER FOR TILT-UP

When using INTRAHARD in a pre-seal application in tilt-up panel areas, an extra application of SpecTilt bondbreaker is recommended as a curing compound as soon as the INTRAHARD has dried to finalize curing. This provides an excellent base for subsequent bondbreaker coats.

APPLICATION FOR EXISTING CONCRETE OR POLISHABLE OVERLAYS

Confirm removal of all surface contaminants. For best results, clean and open the surface with a 100-grit sanding screen or diamond abrasive pad. Remove any dust and residue with a thorough water rinse and scrubber. Water rinse, squeegee the surface, and allow to dry.

Apply INTRAHARD using a quality low-pressure sprayer in a single saturating coat. Uniformly spread INTRAHARD with a soft broom or microfiber applicator to thoroughly coat the concrete, eliminating any puddles or excess. Apply enough material to keep the surface wet for approximately 15 minutes. Apply additional INTRAHARD to porous areas until rejection occurs. Let treated areas dry.

FINAL FINISHING

Final Appearance and Treatment

Surfaces treated with INTRAHARD will increase in hardness, stain resistance, durability, and shine over time with regular maintenance.

To enhance the surface sheen, buff or burnish the dry concrete surface with an orbital floor machine or high-speed propane burnishing machine in both directions with a black, then red floor cleaning pad.

An additional gloss can be achieved on treated surfaces by burnishing with a diamond-impregnated 800-grit or hogs hair pad on a high-speed machine.

If a higher gloss is desired, apply another application of INTRAHARD at 800-1000 square feet per gallon and high-speed burnish with a 1500-grit diamond-impregnated pad.

Please consult a professional applicator for this type of procedure.
