Overview Details Application Documents

Product Description

Monoseal is a one-component, waterproofing membrane based on cementitious binders, selected fine-grained inert materials and special highly-flexible acrylic polymer additives. When mixed with water, it forms an slurry with excellent workability which is easy to apply with a trowel, roller or brush, and which may also be applied on vertical surfaces without slumping. Monoseal bonds extremely well to all surfaces in concrete, masonry, ceramic and marble, if they are mechanically stable and clean.

Field of Application

· Interior and exterior use.

· For waterproofing before installing all types of tiles.

· Swimming pools, fountains, and water features.

· Terraces and balconies over unoccupied spaces.

· Restoring old balconies without removing the existing floor.

· Shower pans, stalls, and tub surround.

· Protection of concrete from aging and carbonation

· Protection of concrete on grade.

Application Procedure

Preparing the substrate

All substrates must be mechanically strong, free of dirt, oil, grease, paint, laitance, concrete sealers, efflorescence, or curing compounds. Any grease or wax must be removed from old ceramic floors using a basic detergent. Screeds and concrete must be completely cured, at least 30 days for screeds and 3 months for concrete. Prime highly absorbent surfaces like lightweight concrete with Seal Primer or DCI Grip Primer to improve adhesion. For exterior applications, always maintain expansion joints from the substrate and treat with DCI Tape W12. For all coves, corners, columns, expansion joints, floor/wall transitions, and other changes in substrate plane, treat with appropriate TAPE before application of Monoseal.

Preparing the product

Pour 6-7 liters of water into a clean container and slowly add Monoseal while mixing. Mix thoroughly for a further 3 minutes until it is completely blended, making sure that no powder remains attached to the sides and bottom of the container. A low-speed mechanical agitator is recommended for this operation, to avoid too much air being entrapped in the mix. Avoid mixing the product manually.

Applying the product

Apply Monoseal within 60 minutes after preparation. Applied on the prepared surface to a feather edge with a thin layer of Monoseal with a smooth trowel or brush; then, while the first coat is still fresh, apply a second coat to form a final thickness of at least 2 mm thick. In the case of waterproofing terraces, balconies, basins, and swimming pools, we recommend embedding alkali-resistant reinforcement mesh in the first layer of Monoseal while it is still fresh. The mesh must be used in areas with either small cracks or regions under particular stress. After installing the mesh, finish off the surface with a flat trowel and apply a second layer of Monoseal when the first one has set (after 4-5 hours). After applying Monoseal, wait 5 days for curing before laying ceramic tiles.
