The leather would otherwise dry out and get brittle over time. Therefore, waterproofing should never be considered to be sufficient "leather care", but only as moisture protection. In addition to protecting against the penetration of moisture, leather also needs a re-greasing depending on the type of use, so that it remains soft and/or UV filters, so that it does not fade and/or frictional wearers so that it does not wear so quickly. Leather care is to preserve the good condition of a leather as long as possible. However, water-repellents only have the function of preventing water penetration. Important! Waterproofing is frequently seen as " leather care". Since waterproofing is generally applied to very porous leather, this reduction can be neglected. Heat increases the water-repellent effect.ĬOLOURLOCK WATERPROOFING SPRAY FOR NUBUCK, SUEDE & FABRICSīy applying an aerosol water-repellent, the breathability of the leather is reduced by about 5 to 10 percent. At the first treatment, waterproofing must be applied several times and must be sufficiently dried. The most effective are aerosol and solvent-based waterproofing products. For this reason products have a strong smell to avoid inhalation. The lungs don't absorb oxygen, causing suffocation. The highest danger is spraying in small, enclosed rooms without ventilation. If sprayed outside and not in direct contact with the spray mist, there is no danger. Therefore, always observe the safety instructions. Important! Waterproofing sprays can damage the lungs. Suede, nubuck and aniline leather should not be exposed to excessive moisture, even with good impregnation! Sensitive leather should not be exposed to bad weather, despite waterproofing. Waterproofing does not completely protect. Important! A waterproofing never makes a leather as water-repellent as a surface colouration. Waterproofing treatments can also reduce certain types of soiling.Ī surface colouring is the best protection, but the leather does not feel so natural.Sensitive leather looks used and becomes stiffer after becoming soaked.The stain sensitivity caused by water marks is reduced.The leather objects don't get heavy due to penetrating water.Feet don't get wet and also the rest of the body is protected from moisture and cold ( leather pants, leather jackets, leather hats, leather gloves).A completely wet shoe or a completely wet jacket is no longer breathable. Breathing activity is reduced when water is drawn in.Laboratory test of the water-repellent properties of a nubuck leather.Īdvantages of preventing porous leather from absorbing moisture: Open-pored leather such as aniline leather or suede and nubuck do not have this protective layer and must therefore be adjusted to be as water-repellent as possible during the manufacturing process. Leather with a pigment finish has a stronger water-repellent property due to the finish. The end user is more familiar with the waterproofing products as aerosol cans or as water-based pump spray products, which are available in every department store or in shoe shops and are used for re-impregnation. To the best possible leather quality, the tanner has to balance the leather's waterproofness, breathability and naturalness of the leather. Hydrophobic refatting agents are then used for refatting and waterproofing and on pigmented leather water-resistant finishes are then applied. shoes and clothing leather) is treated at several points in the manufacturing process in such a way that the best possible waterproofing effect is achieved. In the tannery, leather exposed to the weather (e.g. "hydrophobic" is the expression in the leather production and the end customers speak of "waterproofed leather". The same thing is meant with "waterproofed" or "hydrophobic". Leather is waterproofed or hydrophobic to make it impermeable to water.
