DENSACRETE HYBRID is a concrete densification sealer based on innovative silicate technology containing potassium and lithium silicates. This non-film forming penetrating sealer deeply penetrates and blocks concrete capillaries, and rapidly reacts with the substrate to form a hard, dust-proof, and colour-enhanced finish. Concrete polishing can further produce a smooth or glossy surface. After treatment, DENSACRETE HYBRID does not leave visible efflorescence.
Apply DENSACRETE HYBRID to densify and seal polished concrete surfaces, including residential floors, commercial car parks, and factory or warehouse flooring. Use it on new or existing concrete slabs to strengthen the surface, prevent dusting, and achieve a hard, smooth or glossy, and colour-enhanced polished finish. You can also use the sealer on other masonry substrates such as natural stone, clay bricks, and ceramic tiles. Always conduct a suitability test before application to confirm the product’s effectiveness for your intended purpose.
Before applying DENSACRETE HYBRID, thoroughly clean the concrete surface to remove any contaminants that could hinder sealer penetration. Allow the surface to dry completely.
Ensure new concrete is properly cured. Remove curing compounds, release agents, and surface coatings or membranes, then clean and dry the surface before application. If the concrete has undergone acid treatment, neutralise it fully, rinse thoroughly with water, and allow it to dry.
For polished concrete, grind the surface to 200 grit or the desired finish to expose capillaries or aggregates. This step maximises sealer absorption and ensures optimal densification and the intended surface finish with DENSACRETE HYBRID.
Use DENSACRETE HYBRID as a ready-to-use sealer, or dilute it if required. Apply the sealer with a low-pressure hand sprayer, brush, or broom, ensuring an even flood across the surface. Avoid pooling during application.
To maximise absorption, maintain a mirror-like wet film on the surface for up to 30 minutes. If the surface quickly absorbs the first coat, immediately apply a second coat while the surface remains wet (wet-on-wet method). For porous or permeable concrete, repeat the wet-on-wet application until the surface reaches saturation and no longer absorbs the sealer.
Remove any excess sealer that remains unabsorbed within 30 minutes. If left to dry, excess product may form unwanted residues that become difficult to remove once cured.
To achieve a polished finish, polish or buff the concrete after the previously applied DENSACRETE HYBRID has cured and dried. Apply an additional coat of DENSACRETE HYBRID after each polishing cycle if needed. Repeat the polishing and reapplication process until you reach the desired surface finish.
If you require water and oil resistance, apply TECH-DRY’s water and oil resistant densification sealer, or another suitable oil and water repellent sealer, as a topcoat after the final polish. For further information, contact Tech-Dry on (03) 9699 8202.
Adjust the application rate of DENSACRETE HYBRID according to the concrete’s porosity. Dense or newly poured concrete absorbs less sealer, while porous, permeable, or aged concrete absorbs more. Expect a consumption rate between 5–20 m² per litre per coat, though actual rates may vary significantly outside this range.
Curing begins immediately after application. Allow at least 24 hours for initial curing and avoid heavy traffic or rain during this period. For optimal densification, allow the surface to cure for 7 days or longer.

DENSACRETE HYBRID penetrates concrete, blocks pores and capillaries, and hardens the surface. However, the extent of pore blocking, surface hardening, and water resistance depends on multiple site-specific factors beyond the manufacturer’s control. To confirm product suitability, conduct a pilot test on site before full application. If uncertain, contact Tech-Dry on (03) 9699 8202 for guidance.
Wear appropriate protective gear to prevent skin or eye contact with DENSACRETE HYBRID, an alkaline solution. Although vapour inhalation risk is low, use an air-purifying respirator if exposed to high vapour concentrations. Wash hands thoroughly after handling.
Use the sealer before its use-by date for best results. Store the product in its sealed original container below 25°C. Once opened, use the contents promptly to avoid degradation.
Keep this product away from aluminium surfaces. Keep out of reach of children.
DENSACRETE HYBRID is available in 20, 200 and 1,000 litre packages.
