Hydronylon is a product used in construction, refurbishment or roof renovation projects. It is used in the production of waterproofing and roofing. Hydronylon, as a liquid substance, is applied to asphalt, bituminous and felt roofing, using a brush, paint roller or airless sprayer. As a result, hydronylon creates a waterproofing membrane. Before applying hydronylon, the roof surface must be properly prepared. All non-adherent parts of the felt must be removed, felt replaced with a new one, and the roof should be washed using water under pressure to remove all dust and dirt. Only a clean and dried roof surface can be waterproofed with hydronylon. Hydronylon is sometimes used for waterproofing ordinary residential buildings as well as large industrial and commercial buildings. Work with Hydronylon is certified and the product manufacturer offers a 10-year warranty.
