Combining the mechanical and chemical protective properties of lithium silicate, with the antibacterial activity provided by the latest generation of silver ions and biocides, the treatment performs a self-defensive action on the surface.

If the microorganism were to come into contact with the treated surface, the Silver ions would be able to penetrate the cell membrane to bind to DNA-RNA, block the survival of the enzymatic cells of the respiration by interrupting multiplication, and causing death. Microbiological tests have shown that in 24 hours, 99.999% of the bacterial load was eliminated.

CONCRETE HARDERNER H10 WP ANTIBACTERIAL

FIELDS OF APPLICATION

Incorporated treatment for transparent impregnation of Concrete or Cement, indoor, outdoor, new or existing floors that need to implement abrasion strength and hardness, impermeability to liquids, not altering their breathability, offers a stable aesthetic degree while offering the possibility for the surface to reduce any bacterial load.

Intended for residential, commercial and production areas such as:

• In the regulations for health and safety at the work place, as anti-bacterial nesting.

• Densifier for new floors.

• Densifier for existing floors.

• Architecturalconcretefloors,shops,showrooms,production,packagingandwarehouse areas.

• Cement plasters.

• Prefabricated panels or products in cement.

• Sealing and anti-dust treatments.

• Treatment in the smoothing of concrete floors.

ADVANTAGES

Floors treated with Concrete Hardener H10-WP Antibacterial acquire: antibacterial activity, water repellency, greater hardness, superior scratch resistance, high resistance to chemical agents.

• ANTIBACTERIAL ACTIVITY R≥5 (ISO 22196) 99.999% REDUCTION IN BACTERIAL LOAD
  

• MOULD RESISTANT (UNI 11021)

CONCRETE HARDERNER H10 WP ANTIBACTERIAL

Concrete improves considerably, both in appearance and technical features, through surface treatment with CONCRETE HARDENER H10 WP ANTIBACTERIAL. This penetrates into the porosity of the concrete, chemically reacts with Ca(OH)2, produced by the hydration of the cement to form calcium silicate hydrate.

The impregnation of the pores, besides improving aesthetics, drastically reduces the permeability to water, but not to vapour, increasing the surface hardness, the durability of the concrete and in particular the resistance to acid aggression. By allowing humidity to escape, risks due to the freeze-thaw cycle are avoided.

CONCRETE HARDENER H10 WP ANTIBACTERIAL exerts an anti-corrosive action on metals that it comes into contact with, such as concrete reinforcement.

CONCRETE HARDENER H10 WP ANTIBACTERIAL penetrates into the porosity of the cement and, the very first application completely invades all the porosity, even capillary, reacting with Ca++ ions as mentioned above. The formed gel slowly contracts by 20% leaving the pores filled with 80% of the initial volume.

After the second application, the pores remain empty for 20×0.2 = 4% and full for 96%.

After the third application, the pores remain empty for 20%×4 = 0.8% empty and full for 99.2%,i.e.practically full and there fore inaccessible to liquids.The silicate anions contained in CONCRETE HARDENERH 10 WP ANTIBACTERIAL react with the calciumions present in the hardened cement, forming a silicate calcium gel resistant to water and other liquids, depending on the reaction: Ca++ + SinO2n+1 ->CaO ∙ SinO2n+1.

This reaction occurs inside the pores ofthe cement. The Ca-silicategelclogs the porosities, makingthe cement waterproof to liquids and at the same time harder, more resistant to wear, insensitive to carbonation and more resistant to the aggressive action of acids.

CONCRETE HARDERNER H10 WP ANTIBACTERIAL

ADVANTAGES

The CONCRETE HARDENER H10 WP ANTIBACTERIAL in contact with metals forms monomolecular films of metallic silicates, impervious to oxygen and acids and there fore acts as anticorrosive.

The CONCRETE HARDENER H10 WP ANTIBACTERIAL is able to penetrate into the capillaries of the concrete thanks to its low viscosity and especially low surface tension that sets it apart from other products that you can find on the market.

Thanks toits features, it penetrates deeper and allows you to achieve excellent waterproofing.

SURFACE TREATED WITH
CONCRETE HARDENER H10 WP ANTIBACTERIAL

USE

Slightly shake beforehand and apply the product on the dusted, cohesive and dry surface with a low pressure or manual spray pump, spreading evenly with a dampened microfibre cloth or floor polish. In the case of existing floors resting on the ground, make sure there are no damp areas or negative pressure.

>> Attention: surfaces that have been cleaned or treated with acidic substances should be neutralised before the intervention.

Use industrial mops on surfaces with a rough profile such as brushed concrete. It is necessary that the product does not dry before it has penetrated deeply. If absorption is immediate, adjust the amount in order to keep the substrate damp with product for at least 30 minutes. It will be optional to apply the next coat within 30′-60′ (depending on environmental conditions), forming a saturation impregnation but making sure to remove any excess. If the waiting time between coats is delayed, the initial development of the special features of the treatment (such as hydrophobia of the substrate) would require a slight mechanical action in order to facilitate the laying of the next coat.

The treatment as a densifying agent can be carried out on freshly cast cement, after trowelling or smoothing, always recommending a preliminary test in order to verify the absence of interference.

3 days after the first application, the surface can be wetted with water to check its absorption, bearing in mindthat the complete development of the features takes place gradually and on average in 15 – 30 days.

Invery old cements, the calcium present is almost allinsolu bleand there fore not capable of generating Ca++. Inthis case, a preliminary treatment with a 5% solution of calcium nitrate or calcium acetate is required. The yield of CONCRETE HARDENER H10 WP ANTIBACTERIAL depends on the roughness and absorbing power of the substrate as well as the laying method. In smoothing cycles, 15-20m2/L.
