MC-RockMortar MW G

• PRODUCT PROPERTIES:

➢ Lightweight formulation enabling high build in overhead position.
➢ One-component, polymer modified, chloride free and hydraulic mortar.
➢ Suitable for spray application by wet-spray techniques.
➢ Suitable for thickness of 5 to 50 mm.
➢ Shrinkage-compensated and excellent adhesion.
➢ Ideal application and hardening times.
➢ Available in many colors.

• AREAS OF APPLICATION:

➢ Concrete repair of large area and catching of small and localized structural repairs. MC-RockMortar MW G provides a protection for embedded steel reinforcement. It is ideal for vertical and overhead repair operations.
➢ Light weight built-up in landscaping or sculpturing works.

• APPLICATION:

➢ Surface Treatment: The surface must be clean and free from all loose particles dust, oil and other contaminants. The substrate must have sufficient roughness, e.g., sound aggregates should be visible.
➢ Manual Application: Before application of MC-RockMortar MW G, a polymer cement slurry bonding coat should be brushed into the pro-wetted surface. The surface should be moist but saturated with water. Very absorbent substrates have to be ore-moistened several times I necessary. The high build repair mortar. MC-RockMortar MW G should then be applied “fresh-on-fresh” to the bond coat by trowel or float. The bond coat shall be based on MC- Bond Coat.
➢ Mixing: MC-RockMortar MW G is a single-component mortar which is mixed with water. The dry powder is slowly added to water and mixed thoroughly until a homogeneous, creamy consistency is achieved. Forced action mixers are recommended. Mixing should take approx. 3 minutes. Mixing by hand is not permitted. Use full pack-sizes only.
➢ Mixing Ratio: For a 25 kg sack of MC-RockMortar MW G, approximately 3.8 – 4.0 litres of water is required. As with all cementitious products, the quantity of water needed may be varied lightly.
➢ Application:
– MC-RockMortar MW G can either be applied by hand with floats or trowels, or by wet-spray techniques.
– It is recommended to apply in layers of up to 50 mm each. For thicker application, apply overcoat only after the previous coat has attained the final set. MC-RockMortar MW G should not be applied at temperature below +5˚C (air and substrate). Before application of overcoat all loose particles on the surface shall be removed.
➢ Curing: Care must be taken to ensure MC-RockMortar MW G is suitably protected to prevent it from drying out too rapidly, especially from the effects of direct sun and wind. As with all cementitious materials, it shall be protected from rain before its final set.
➢ General: Coverage depends on texture and porosity of the substrate. To determine this exactly, a trial area should be laid and coverage noted.
