Anti-dust chemical hardener for concrete floors and screeds

Code: FLR.0120

Components: 1

Appearance: Liquid

An anti-dust chemical/mechanical revitalising hardener for concrete flooring and screeds, consisting of an aqueous solution of mineral silicates and fluosilicates, activated by specific wetting agents. It is applied in several coats of decreasing dilution in water, with a brush or mechanical “scrubber”. Specific anti-dust treatments for industrial flooring or concrete slabs that have lost their original “vitality”.

It reacts with the calcium compounds, soluble and unstable, present in of concrete products, transforming them into new stable, insoluble and resistant compounds. Consequent increases in resistance to wear and tear of the order of 200% -400%, significant increases in chemical stability, resistance to freeze-thaw cycles etc.


Apply from 0.25 to 0.40 kg of QL FLUOSIL per square metre of surface to be treated.

Use fields

Reactive impregnations for stabilising chemical and mechanical structures and concrete products. Hardening, anti-dust, anti abrasive and anti-corrosion treatments for concrete floorings. Adjustment of the chemical and mechanical performance of products for the industrial, rural and livestock construction (on horizontal surfaces).

Preparation of supports

Application surfaces should be clean, free of soiling, crumbling and non-adhering parts, dust, etc., conveniently saturated with water until they reach the condition "saturated with dry surface".

Use method

Apply, preferably with a brush or with "washer dryer" machine on the basis of the following indications:
- Porous surfaces: repeated applications of a solution of water and QL FLUOSIL at a ratio in 1:1
- Compact surfaces: apply three coats, with decreasing dilution with water. 1a coat 1:3, 2a coat 1:2, 3a coat 1:1.

The consumption of QL FLUOSIL will be proportional to the absorption of the floor to be treated. Indicatively a porous surface will consume about 400 g/m², while a surface with normal porosity will consume 250-300 g/m².

Leave the product to dry between one coat and the next and then, after the last coat, wash with copious amounts of water. Protect glass and aluminium surfaces during application.

Application methods

- Scrubber-dryer machine

- Scrubbing brush

Tool cleaning

- Water

Permitted supports

- Concrete

- Floor screed

Warnings, precautions and Ecology

QL FLUOSIL can be applied on concrete building supports that have a life of at least 30 days. It is not recommended to use QL FLUOSIL in the case of coloured concrete industrial floorings; in these cases, we recommend the use of QL NANO LITHIUM.

Caution, it is a moderately caustic and corrosive product.
