BUILDRITE BLOCKOUT SILOX - Hydrophobic, Easy-to-Clean, Matte Finish Sealer

PRODUCT DESCRIPTION:
BLOCKOUT SILOX is a silane/siloxane-based emulsion water-repellent treatment for use on mineral substrates such as brick, stone, concrete, and mortar. BLOCKOUT SILOX penetrates and provides water repellency by chemically reacting with the substrate. Treated substrates retain their original appearance and have excellent resistance to weathering.
BLOCKOUT SILOX reacts with the atmospheric moisture or pore water present in the substrate, forming a tightly bonded hydrophobic lining within the pores. This process results in a hydrophobic treatment that inhibits water absorption into the substrate. The lining greatly lowers water absorption, while allowing the substrate to breathe.

CUSTOMER BENEFITS:
• Excellent penetration capability is achieved through the small molecular structure, providing effective water repellency.
• Chemically bonds to the substrates
• Performs both on neutral and alkaline substrates
• Extends the life of the treated surface
• Breathable – allows a high degree of water vapor permeability
• Reduces water and chloride intrusion thereby increasing the life of the substrate
• Treated surface will not change the appearance of the substrate.

AREAS OF APPLICATION:
For use on neutral and alkaline mineral substrates that 
require water repellency such as:
• Concrete and mortars
• Brickwork
• Natural stones
• Paver
• Precast concrete
• Cement fiberboards
