QL NANOSIL RAINPROOF is a product in aqueous solution, with high performance fluorinated silane-siloxane polymers, designed to be a greater repellent to water and oil on all absorbent concrete and masonry surfaces, indoors and outdoors. QL NANOSIL RAINPROOF is non-toxic, odourless, non-flammable and very simple to use. QL NANOSIL RAINPROOF has a small molecular structure (0.029 micron) that allows in-depth penetration of the surfaces without modifying the appearance and shine; it offers excellent resistance to water and oil and is resistant to stains caused by spilling oil and seed oil, coffee, ketchup, mustard and other foodstuff substances. QL NANOSIL RAINPROOF reduces the damage caused by frost - defrost and saline efflorescence. Surfaces treated with QL NANOSIL RAINPROOF have no film or surface film. The life expectancy planned for the treated surface is approx. 5 - 10 years (based on the application and use).

It is an odourless, waterproof, oil repellent and stain-proof product for surfaces in concrete and masonry work both for indoors and outdoors. It has exclusive new generation technology formulated on the basis of three different polymers: Silanes, siloxanes and fluoropolymers. It is water based, does not contain solvents and has very low COV emissions.
QL NANOSIL RAINPROOF is a primer used as a water and oil repellent for absorbent surfaces such as concrete, brick, masonry and stone, including: architectural concrete floors in washed gravel, surfaces in concrete, footpaths, blocks in concrete, reconstructed stone, moulded concrete, blocks, road manufactured works in concrete in general.
You are advised to do a test application on a small piece to identify suitability of the product and the result. Leave the surface to dry before application.
1. The surface of the works to treat must be clean, structurally safe and free of wax, dirt, coatings, paint, seasoning agents and chemical residue.
2. Cracks, control joints and construction joints must be adequately prepared and sealed. Cement residue must be removed.
3. Remove dust before applying QL NANOSIL RAINPROOF
4. The concrete surface smoothed with a trowel must be tested in advance to view the penetration capacity and to estimate consumption.
5. Before application, carefully cover and protect windows, frames and any surface that can accidentally come in contact with the product. In the event of a leak, clean with water immediately.
1. Apply the product on concrete surfaces after at least 7 days from completion of the cast
2. Do not apply QL NANOSIL RAINPROOF on surfaces with a temperature under 5°C.
3. Do not apply outside if raining or snowing.
4. QL NANOSIL RAINPROOF must be applied with a low pressure spray, airless sprayer, roller or brush. Apply 1 litre per 5 to 10 m². Consumption varies based on the porosity of the surface.
5. Apply one or more coats based on the surface porosity. Apply the second coat "fresh on fresh", when the first is not yet dry. The drying time time depends on the atmospheric conditions (temperature, humidity, wind, etc.).
6. Do not leave excess product on the surface. Remove the excess product with a clean cloth before drying.
7. On some surfaces with few pores (as marble and granite) spray the surface with clean water before applying QL NANOSIL RAINPROOF. This procedure opens the substrate pores and makes penetration of the product easier.
8. On vertical surfaces, always apply the product from the base upwards.
9. Clean the equipment with water.
Maximum protection is reached after 3-6 days of treatment.
