How To Use HydrophobNeo-L


The HydrophobNeo-L composition does not need preliminary preparation: ready to use.

Application must be to clean, dry to slightly damp surfaces. Remove dust, dirt, oils, efflorescence, wax, coatings or other foreign matter that might block or interfere with product penetration. When applied to wet surfaces the HydrophobNeo-S composition is necessary.

Air temperatures should be a minimum of 23°F and a maximum of 100° F during the application. Do not apply to frozen or frost covered surfaces. Do not apply to surfaces when it is raining or snowing. Make all necessary repairs, including defects, which allow water to enter the construction such as: structural cracks, chips, scratches, mortar joints, etc.

How to apply HydrophobNeo-L

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. When applied to surfaces of nonporous bricks and stones test application is especially required.

How to use HydrophobNeo-L? The HydrophobNeo-L composition can be sprayed, brushed or rolled. Amply saturate the surface with HydrophobNeo-L. Use enough to completely wet the surface. Avoid puddling or ponding. Do not let the product dry on the surface. Roll or brush out puddles. Remove excess of the composition with a dry cloth or sponge. Surfaces with defects (chips, cracks, scratches, etc.) should be treated thoroughly. Small articles can be treated with the product by submerging in the HydrophobNeo water repellent composition for several minutes.

How to use HydrophobNeo-L on highly permeable surfaces? In this case additional coats may be necessary. Apply a first application, wait for 5 – 10 minutes, and then apply a second application “wet on wet.” The second application will require less material than the first. Avoid puddling or ponding.

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.


The HydrophobNeo composition should not be used for the treatment of articles made of any polymeric materials (plastics) as it is ineffective, of any metals (ineffective, corrosion is possible for aluminum alloys). Prevent from being spilled or over sprayed onto these materials. Treated surfaces may be painted with an oil-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. Loss of glass transparency or formation of spots is possible. If being spilled onto glass surfaces remove the composition as soon as possible with a dry or wet cloth. When applied to surfaces of some types of gypsum white fluffy bloom might occur. After drying it may be easily removed with a dry cloth or dry brush.


When stored in original, unopened containers, the warranty storage time is 3 years of date of manufacture (see the package). When being stored for a long time precipitation may occur. Mix thoroughly prior to use. The composition does not freeze at temperature down to minus 5°C (+23°F). After thawing the HydrophobNeo-L properties are the same. Do not store the composition in containers covered with aluminum or zinc coating as well as in glass vessels.


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

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