  • Concrete
  • Clay Brick

HydrophobNeo-L water repellent composition





1,321 Gallon (5 Liters) Containers


1,321 Gallon (5 liters) / Coverage area: 150 to 350 Sq. Ft. (14 to 32 sq. meters), depends on surface porousness. Consumption is approximate and may vary depending on surface porosity, surface texture, concrete condition, climatic conditions, etc. Always apply to a test area first to determine actual consumption before general application.




HydrophobNeo-L water repellent composition is designed to impart water repellent and frost resisting properties to building materials and protect from moisture saturation of building constructions made of concrete, foamed and gas concrete, brick, building stone, gypsum, glass magnesium boards, plastered surfaces.

Features and Benefits

Surfaces treated with HydrophobNeo-L have water-repellent and frost resisting properties. They become resistant to atmospheric precipitation and groundwater.

The HydrophobNeo-L water repellent composition has light antiseptic properties: it prevents from the formation of mould, fungus, etc. HydrophobNeo-L water repellent agent does not form a film – it penetrates the surface to form a water repellent layer within the material to reduce moisture penetration. The product keeps the gas permeability of treated surfaces: material breathes. The HydrophobNeo-L composition improves thermal insulating properties of building materials. The HydrophobNeo-L composition has no smell and colour; does not change the pattern and colour of treated surfaces. The composition is completely fire safe and blast proof. It is safe for environment. The product does not need preliminary preparation: ready for use. The HydrophobNeo-L composition is frost resisting: it can be applied at temperature down to minus 5°C (+23°F).  HydrophobNeo-L water repellent agent is especially recommended to protect from moisture saturation of building constructions made of porous concrete.

When used outdoors treated surfaces keep water repellent effect for approximately 1 – 8 years. Durability of the coating is approximate and may vary depending on surface porosity, surface texture, concrete condition, climatic conditions, etc.



  • Effective protection of fronts from aggressive weather impact;
  • Waterproofing of walls and concrete floors in basement, damp and other rooms;
  • Reliable protection of the objects of country house building from the impact of atmospheric precipitation;
  • Covering slate and tiled roofing, concrete parking lots, driveways, walkways, parapets and footpaths;
  • Use in restoration work;
  • Preservation of the objects of construction in progress for autumn and winter period.


How to apply HydrophobNeo-L


Directions for Use

The HydrophobNeo-L water repellent composition does not need preliminary preparation: ready for use.

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.

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.

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.

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 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.

On highly permeable surfaces, 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.

NOTE: 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 a dry brush.
