Product description:
PROBITANO R20 is a two-component, coloured polyurethane coating, which makes the coated surfaces waterproof, easy to clean and provides medium mechanical and chemical performance as well as easy maintenance. High resistance to ultraviolet radiation makes it particularly suitable for outdoor applications. High adhesion and anti-dust guaranteed by its excellent penetration into the substrate.After hardening, PROBITANO R20 is impermeable to water, resistant to chemical agents, frost and weathering.
Field of application:
- Easy application.
- Excellent adhesion on concrete and metal.
- Impermeable to liquid water and water vapour.
- Hygienic and easy to clean.
- For satin finishes.
- High chemical and mechanical resistance.
- Abrasion resistant.
- Resistant to UV radiation.
- Indoor and outdoor use.
- Vertical and horizontal application.
Substrate preparation:
The substrate must be slightly rough, dry, hard, solid and free of dust or other loose particles such as paint, lime, mortar, plaster, adhesive residues, etc., which may impair adhesion to the substrate.
Before mechanical preparation, varnish, wax, grease, oil and similar contaminants must be removed. Contaminated concrete surfaces must be treated mechanically, either by sanding or diamond grinding, followed by vacuuming.
Any joints or cracks in the concrete substrate where differential movement is expected (e.g. expansion joints) must be respected and properly sealed.
The substrate must have a tensile strength greater than 1.5 N/mm2.
When applied on metallic surfaces sandblasting should be used for cleaning/preparation.
Mixing:
The individual components of PROBITANO R20 must be stirred before mixing.
Mix the two components thoroughly with a low speed stirrer for at least 3 minutes.
Part of the mixture can be reintroduced into the container of the hardener to collect any residues that may remain in the container. The mixture that has been passed through the hardener container is reintroduced into the mixing container and stirred for a further 30 seconds. This mixing process ensures the consistency of the product and that any resin remaining in either container reacts, facilitating subsequent waste management.
After mixing both components, 1Kg of PROBITANO R20, is workable for 30 minutes at a temperature between 18°C and 20°C.
Recommendations:
After mixing the two components of PROBITANO R20, use it immediately. The material does not heat up at the end of the pot life, which is indicated by a slight increase in viscosity, as higher temperatures shorten the pot life and lower temperatures lengthen it.
Limitations:
Always use PROBITANO R20 with ambient and/or substrate temperatures not lower than 10°C and always at least 3°C above the dew point.
Nor can it be applied at ambient and/or substrate temperatures above 30°C or when the ambient humidity exceeds 85%, if the pot-life is exceeded the mixed product loses its characteristics and must be discarded.
All SEIRE products are manufactured under strict quality controls and procedures, however, it is recommended when colour consistency is essential that the products used are from the same batch.
How to apply:
Once components A and B have been mixed, the material is applied directly onto the substrate by short nap roller, brush or air-less. It must be ensured that the entire surface is completely painted and that no puddles of product remain.
The second coat shall be applied as soon as the first coat is sufficiently cured.
This curing time varies according to environmental conditions. Do not allow less than 8 hours at 20ºC between coats.
If more than 48 hours have elapsed, sanding is necessary.
During application and curing, especially in confined areas such as warehouses, etc, adequate ventilation must be ensured.At no time should solvent or thinner be added.
Consumption:
Approximate consumption of PROBITANO R20 is 0.2 to 0.35 kg/m² per coat depending on roughness of the substrate.
Tool cleaning:
PROBITANO R20 can be cleaned from tools and equipment immediately after use using a solvent such as ARDEX RTC. In case the product hardens it can only be removed by mechanical means.
Residues/Spills:
Spillage of any of the products should be collected immediately with sand, vermiculite or any other inert material and deposited in a suitable container for management.Waste management of these spills and empty containers should be carried out following current local legislation.For further information refer to the safety data sheet.
Storage:
The shelf life of PROBITANO R20 is 12 months, in the original closed containers. Storage should be in a dry place between +5ºC and +30ºC. Protection from frost and direct sunlight and heat sources is required.
Precautions:
Irritating to eyes and skin, depending on sensitivity. Hazardous to health if swallowed.
In case of prolonged exposure may cause burns. Avoid contact with eyes and skin.
In case of contact with eyes, rinse immediately with plenty of clean water and seek medical advice.
Mixing should be carried out with protective goggles and gloves. These safety precautions must also be observed when applying the product.
If the product is applied indoors, ensure that the room is well ventilated. After drying the product is physiologically and ecologically neutral.
