Densifiers & Hardeners
Densi + Anti Microbial
Densi Anti-Micro is a densifier formulated to strengthen concrete while supporting resistance to microbial growth in moisture-sensitive environments.
Available Sizes
Key Features
- Increases hardness and durability
- Reduces dusting
- Supports environments with moisture and microbial concerns
- Deep-penetrating formulation
- Non-film-forming
Ideal For
- food preparation areas
- wet rooms and moisture-prone spaces
- healthcare and hygiene-sensitive environments
- high-traffic surfaces requiring improved durability
How It Works
Densi Anti-Micro combines the densification chemistry of DensiCrete with antimicrobial additives designed to help inhibit microbial activity where moisture is present.
Application
- 1
Clean and prepare the surface.
- 2
Saturate evenly with a sprayer.
- 3
Keep the surface wet for 20–30 minutes.
- 4
Broom lightly to assist penetration.
- 5
Allow to dry; remove residue if required.
Coverage & Drying Times

Start by identifying what you want the concrete to do: become harder, resist moisture, repel stains, or improve appearance. Each DuraCore product is designed around one of these outcomes.
- Hardness / reduced dusting → choose a densifier (DensiCrete or Densi Anti-Micro)
- Moisture control → choose Moisture Proof or Moisture Prevention depending on timing
- Water/oil repellency → choose a repeller (Repeller or Densi-Repeller)
- Improved appearance/surface finish → choose AquaSeal or Lustre Crete
A densifier strengthens concrete internally, while a moisture control treatment reduces moisture movement within the slab.
- Densifiers create more C-S-H inside the slab → harder, less dusty, better wear resistance
- Moisture treatments reduce vapour pathways → stabilise slabs for flooring and reduce moisture-related failures
- They solve different problems and can be used together in some cases
Densifiers work inside the concrete to make it harder. Sealers work on the surface to protect appearance and improve cleanability.
- Densifiers: penetrate and chemically harden the slab
- Sealers: create a protective film that enhances the look and provides light surface protection
- They are often used together in polished or decorative concrete systems
Use a penetrating repeller when you want protection without altering the concrete's appearance or sheen.
- you want a natural finish
- the surface receives water, oil, or food spills
- UV stability is needed (outdoors)
- slip resistance must be maintained
- you want visual enhancement
- you want a subtle sheen or finished look
A penetrating repeller is usually the best option for outdoor areas, especially driveways.
- Repeller: best protection against water, oil, and everyday contaminants
- Densi-Repeller: good option if you also want increased hardness
- AquaSeal or Lustre Crete: use only if you want an enhanced appearance (but film-formers may require more maintenance outdoors)
