Protective coatings

Paint coatings for roofing and cladding sheets protect the material from weather conditions and mechanical damage, while providing an aesthetic finish. The Pruszyński company offers a wide range of coatings to suit every need.

Types of coatings

Polyester gloss, protective coating PS25

Metallic gloss polyester, protective coating PS25

Basic polyester coatings

Up to 30 years of warranty

Polyester coatings are resistant to UV radiation (level in accordance with the RUV4 classification - the most demanding category of the European standard EN 10169/2).
The paints used have exceptional resistance to photochemical aging processes, which makes this product an ideal solution for use in projects in which aesthetic values, strength and durability of color are particularly important.

Polyurethane coatings

Up to 50 years of warranty

Polyurethane coatings are very resistant to UV radiation (level in line with the RUV4 classification - the most demanding category of the European standard EN 10169/2). The paints used have exceptional resistance to photochemical aging processes, which makes this product an ideal solution for use in projects in which aesthetic values, strength and durability of color are particularly important.
The thicker layer of paint provides increased corrosion resistance, which is an advantage in urban or industrial environments. For this reason, this product is better suitable for use in difficult environmental conditions than a polyester coating.

Colorcoat PRISMA ®

Special coatings

Up to 40 years of warranty

COLORCOAT series coatings have been developed for particularly difficult conditions of high humidity. Thanks to technologically advanced recovery processes, as well as the unique composition managed to achieve one of the highest standards of anti -corrosive resistance - C5. Such standards are required from products that must be used in extremely demanding circumstances. An example here can be coastal buildings, constantly exposed to a high level of humidity and salt water, as well as industrial buildings, where the sheet will be operated in high humidity conditions, such as swimming pools, processing plants and sewage treatment plants.

Recommendations

Maintenance and washing

In order to extend durability of roofs and elevations it’s recommended to check and conservative it.
Inspection – One time a year (it’s best in spring) there should be inspection of roof/elevation in order to early detection of possible damage.
Cleaning of steel sheet – Roof and elevation made of steel sheets require cleaning at least once a year. Stratifying dirt on steel sheet may cause uneven discoloration of lacquer (because of uneven impact of UV beams), and lower protection to corrosion(dust traps humidity on steel sheets which causes damage). Dirty and stained spots can be cleaned by soft brush and water (temp. max. 60c). If it is necessary it is permitted to use some light detergent (ph 6/7, max 10% solution). There also can be used pressed water(max. 100bar) to cleaning, however the beam of water cannot be applicated too near of surface of sheets(min. 30 cm), also it shouldn’t be perpendicularly to surface. Near the connections water beam should be directed to bottom, to avoid water of entering cracks near connections. With old surfaces of steel sheets we should deal with high cautiously. Cleaning should be conducted from top to bottom, and cleaned spots should be rinsed out immediately.
It is not permitted to use scouring powders, nitro solvent, chlorine liquor, aromatised substances, substances with Amon chloride or sodium.
Damages – Possible damages during guarantee should be consulted with Contractor of roof/elevation and can be repaired only with his written permission.Repair of damages on small surfaces is done with quick-drying varnish. However painting big surfaces should be done with special industrial paints to renovating coverings. Painting should be limited only to special damaged spots (scratches to steel, centres of corrosion etc.)Preparation of surface to painting should be done with generally accepted rules. It is necessary to precisely remove all signs of corrosion – best with special brush or close-grained sandpaper. Then that surface should be undusted, degreased and cleaned. To degrease extraction naptha or water with addition of surfactant(best with 1-2%solution of ammoniac) can be used. Repaired spots may be different in colour compared to original steel sheets because of natural impact of atmospheric phenomenon (ageing of varnish due to impact of UV radiation)
ATTENTION!– During inspecting, cleaning, conservation and repair all work safety regulations should be obeyed.Pruszyński Sp. z o.o. is not in charge of possible accidents during carrying out all following actions.
