How To Use HydrophobNeo-W


The HydrophobNeo-W composition is supplied in the form of two solutions (two component packaging).

Before using the solution №2 is poured into the solution №1 followed by good mixing (shaking), after this the composition is ready to use. The mixed composition may be stored for several weeks in the closed (but not hermetically) container. The application and drying works should be held in well aired rooms or at the open air.

Application must be to clean, dry to slightly damp surfaces. When applied to wet surface the penetration depth of the composition decreases drastically. The HydrophobNeo-W composition gives the best water-repellent properties when used for well dried wood. Remove dust, dirt, oils, efflorescence, wax, coatings or other foreign matter that might block or interfere with product penetration. It is not recommended to be used to protect surfaces treated before with drying oil, lacquers, paints or another film forming compositions. Any treatment with non film forming compositions (mordants, fire retardants, antiseptics) should be held before waterproof treatment. How to use HydrophobNeo-W for external timber structures? When applied to surfaces used outdoors it is recommended that wood surfaces be preliminary treated with colourless water based antiseptics.

Air temperatures should be a minimum of 32°F (0°C) and a maximum of 95°F (35°C) during the application. Do not apply to frozen or frost covered surfaces. Do not apply to surfaces when it is raining or snowing.

Always perform a test application to a small area of surface for proper penetration on each type of surface before starting full-scale application to determine suitability and final appearance.

How to use HydrophobNeo-W? The composition is applied in one layer by brush, applicator roll, sponge or sprayer in amount enough to wet the surface but without runs. Excess of the composition should be removed. The treated articles should be conditioned for several hours (at room temperature), after this they are ready for use. At lower temperatures the conditioning time increases. Drying time: two to six hours, depending on temperature and humidity. Optimum water repellency is developed within 24 hours. Protect surfaces from rainfall for 24 hours following treatment.

Consumption is 0.1 – 0.25 L/m2. Increasing of the amount of the applied composition does not improve the water-repellent properties but lead to formation of rubberlike film at the wood surface.

Treated surfaces may be painted a week later, if it is necessary. It is recommended that the treated surfaces be wiped with a wet cloth or be washed with clean water in 1-2 days before further treatment.


The HydrophobNeo-W water repellent composition cannot completely substitute the antiseptics! Treated surfaces may be painted with an oil-based or alkyd based (not a water-based!) paint. Testing is always necessary to ensure adhesion and compatibility. Prevent from being spilled or over sprayed onto glass surfaces. If being spilled onto glass surfaces remove the composition with a dry or wet cloth.


When stored in original, unopened containers, the warranty storage time is 2 years of date of manufacture (see the package). During the composition storage influence of increased temperatures /over +35°C (+95°F)/ and direct sunlight should be excluded. The composition does not freeze at temperatures down to minus 75°C (-103°F).


Keep out of reach of children. Read label before use.

Use only outdoors or in a well-ventilated area. Contains isopropanol. Keep away from open flames. Alcohol odour completely disappears in 24 hours.

Composition application should be held in protective glasses and gloves. When sprayer is used, respirator is needed.

After drying the coating is harmless for men and animals.
