KUT NANOSIL WB

DESCRIPTION:
KUT NANOSIL WB is water based single component penetrating silane-siloxane based system, ready to use which penetrate deep into porous substrates and then react to produce a bonded hydrophobic lining to the pores. KUT NANOSIL WB is colorless when dry, non-staining, non-yellowing, and non-filming sealer used to protect concrete and masonry surfaces without altering their appearance or the texture of the treated surface. KUT NANOSIL WB is breathable, nonflammable & has excellent resistance to weathering. Even though allowing passage of water vapors from the substrate it significantly reduces the absorption of water and water borne salts.

USES:
KUT NANOSIL WB is an excellent water repellent for many absorbent mineral substrates, such as bricks, sand-lime brick, natural sandstone and mineral plasters. It is not so suitable for less absorbent, dense natural stone, especially limestone, marble and reinforced concrete for bridges and roads.
Owing to its aqueous consistency and storage stability KUT NANOSIL WB is ideal for in plant hydrophobation of building materials made of clay, aerated concrete, sand-lime brick, mineral fibers and lightweight aggregate.
KUT NANOSIL WB may also serve as a water-repellent primer for emulsion paints and plasters, silicone resin emulsion paints and silicone resin plasters.

APPLICATION:
Surface Preparation: Cure new concrete 28 days before application. Surface must be structurally sound, clean, dry, free of dust, dirt, paint, efflorescence, laitance, and other contaminants that will prevent the proper penetration of KUT NANOSIL WB. Prior to application, joints or cracks must be properly sealed or filled. If acid is used for cleaning, neutralize completely before KUT NANOSIL WB application. A dry substrate allows better penetration of the sealer.
Application Instructions: Apply KUT NANOSIL WB in the usual way; flooding is the preferred way. Two "wet on wet" coats are needed to ensure complete coverage. If it starts to rain, stop treatment and cover the impregnated areas.
For porous surfaces two or more saturation coats of KUT NANOSIL WB may be required. Apply a test patch to evaluate surface appearance and effectiveness of the coverage rate. If in doubt about the condition of the substrate, the ASPEC Technical Dept. should be consulted. KUT NANOSIL WB should be allowed to dry for a minimum of 2 hours (at 20°C) before continuing.
