MasterProtect® H1100 is a class of silanes that has a very low molecular size, which ensures effective impregnation of concrete and masonry surfaces through deep (3-8 mm) penetration into the pore structure. Impregnated It reacts with moisture and forms permanently bonded hydrophobic lining on the pore-walls of the substrate.
Effective water repellence – Durability. Inhibits ingress of water borne aggressive agents such as chlorides.
Minimizes surface efflorescence – Clean appearance of masonry surfaces.
Breathable – Allows excess water vapour to evaporate from the substrate.
Highly penetrative – Ensures long-term effectiveness even on surfaces exposed to traffic (e.g.: car parks).
Elastomeric – capable of bridging cracks.
Application
Recommended for application to most of the cementitious, masonry and mineral substrates above ground, not subject to hydrostatic pressure. Applications include treating the surfaces of:
Bridge decks, abutments, piers, soffits, etc.
Beams, columns and walls of buildings
Exposed brick structures
Car parks
Marine structures
The product is designed for the protection of reinforced
Dosage
Approximately 170 ml/m2 (150 g/m2) In windy conditions or with very porous substrates reduce the application rate and apply in two coats of approximately 90 ml/m2 per coat allowing at least two hours between coats.
