• PRODUCT PROPERTIES:

➢ Two-component cementitious waterproofing system modified with polymer to enhance waterproofing performance.
➢ Forms a waterproof and moisture-resistant membrane when cured, while still allowing substrate vapor permeability.
➢ Easy-to-apply, thixotropic paste-like consistency.
➢ Excellent crack-bridging capability.
➢ Strong adhesion to concrete and other cementitious substrates.

• AREAS OF APPLICATION:

➢ Wet areas for both interior and exterior use.
➢ Bathrooms, laundry rooms, kitchens, wash areas, balconies, utility spaces, etc.
➢ Swimming pools, water tanks, planters and landscaping troughs.
➢ Roof slabs, exterior walls, parapets, concrete gutters and drainage channels.
➢ Balconies and terraces.

• PRODUCT CHARACTERISTICS:

• APPLICATION NOTES:

➢ Substrate preparation:
– The substrate must be sound firm, free of dirt, grease, old paint or other impurities which may affect the adhesion of the waterproofing layer.
– Flatten sharp, convex positions. Use a high-pressure water jet or suitable equipment to remove debris and clean the surface.
– Fill up cracks, pits on the substrate.
– Substrate with high water absorption should be moistened to saturation but without standing water.
– Wall corners and edges must be chamfered with plaster or other appropriate materials.

➢ Mixing:
– Mixing ratio: Component A (Powder) : Component B (Liquid) = 2 : 1 (By weight).
– Pour the component B (Liquid) into a clean bucket, slowly sprinkling component A (Powder) into component B (Liquid) using a slow-speed mixer.
– Mix for about 3 minutes, carefully mixing to until the mixture is homogeneous without lumps. Do not mix at high speed or mix for too long to avoid foaming in the mixture.
– The product after mixing should wait 3-5 minutes for maturing of the chemicals, then it should be applied immediately. After the pot life time, discard it. Do not add water and mix again.
– To ensure the ratio of the mixture, the product must be mixed as a whole, not in parts.

➢ Application:
– MC-Proof SP 180 must be applied with a minimum of 2 coats. The first coat is applied by broom, brush or trowel in only one direction until the surface is fully covered. The second coat is applied as soon as the first coat begins to dry, about 3-6 hours depending on environmental conditions. Use a soft brush to sweep in a direction perpendicular to the first layer. In case the first coat is too dry, it should be lightly moistened with water before applying the second coat.
– The recommended thickness of the finish waterproofing is at least 1 mm for areas not subject to hydrostatic pressure such as bathrooms, balconies, kitchens, terraces,…
– MC-Proof SP 180 can be applied with a suitable sprayer and must be tested prior to application.

➢ Curing:
– Avoid applying in direct sunlight, surface temperature >35°C or in windy conditions. The waterproofing layer after application is protected from rain or running water for at least 24 hours to preserve the integrity of the waterproofing membrane. Early exposure to water can affect the color of the waterproofing without affecting the quality.
– MC-Proof SP 180 waterproofing membrane requires a protective screed on it.

➢ Cleaning:
– Use clean water to clean tools and equipment immediately after construction.
– When the product is solidified, it can only be cleaned by mechanical means.

➢ Safety information: MC-Proof SP 180 does not contain hazardous substances requiring labeling and very safe in normal working conditions such as wearing gloves, goggles,…
