How To Use HydrophobNeo-S
The HydrophobNeo-S 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. HydrophobNeo-S water repellent agent may be applied both to dry and damp surfaces of building constructions. When properly applied to slightly wet surfaces the HydrophobNeo-S efficiency almost does not change. Yet best performance is achieved on a clean, thoroughly dried and absorbent surface.
Air temperatures should be a minimum of 14°F and a maximum of 95° 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.
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 non-porous bricks and stones test application is especially required.
The HydrophobNeo-S composition can be sprayed, brushed or rolled. Amply saturate the surface with HydrophobNeo-S. 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 a 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 (penetration depth depends on exposure time).
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.
How to use HydrophobNeo-S on highly permeable surfaces? In this case additional coats may be necessary. Apply a first application, allow the composition to penetrate within the surface of building material, and then apply a second application. Avoid puddling or ponding.
A third application may be applied to the surface a few days later, if it is necessary. “Wet look” effect may occur as a result of this additional application.
How to use HydrophobNeo-S on non-porous stone surfaces? When applied to polished granite and marble surfaces, only a single application is necessary. Apply the single application, wait for 15 – 20 minutes, and then remove excess of the composition with a dry cloth and wipe the surface thoroughly. When applied to polished surfaces with engraved images, slight darkening of unpainted images may occur. Optimum water repellency is developed within 24 hours.
NOTE:
The HydrophobNeo composition should not be used for the treatment of articles made of any polymeric materials (plastics) or of any metals as it is ineffective. 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. If being spilled onto glass surfaces remove the composition with a dry or wet cloth.
Storage
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 50°C (-58°F).
Precautions
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.
