Morcem^® Dry F

Technical Characteristics

Two-component, cement-based waterproofing system composed of selected fine aggregates, additives and polymer-modified binders

Advantages and Uses

• Excellent crack-bridging waterproofing membrane capable of accommodating cracks up to approximately 2 mm.
• Provides excellent flexibility with elongation around 120%.
• Strong adhesion to cementitious, ceramic, and stone substrates.
• Suitable for both new structures and refurbishment applications.
• Compatible with tile finishes, mosaics, and natural stone.
• Certified as per relevant international waterproofing and protection standards.
• Nontoxic: Can be safely used as internal waterproofing of potable water tanks.
• The membrane remains flexible under varying exposure conditions.
• It withstands exposure to chlorine commonly used in swimming pools.
• Excellent adhesion to concrete substrates.
• High crack-bridging capability under static and dynamic conditions.
• Low water absorption and strong impermeability.
• Good vapor permeability while remaining waterproof.
• Resistance to freeze-thaw cycles and chemical exposure.

Suitable Substrates

• The surface of application must be thoroughly prepared by mechanical means, to remove all loose particles,laitance, etc.
• Oil and grease, if any, must be de-greased with suitable solvents. It then must be washed off with jet of water and brought to touch dry state.
• Any surface undulations, cracks and crevices must be duly filled or repaired with approved repairing mortar or MorcemSeal Todo 1.
• Strong adhesion to cementitious, ceramic, and stone substrates.

Application Procedure

Mixing:

• Using a slow speed mechanical mixer and a clean suitable mixing vessel, slowly add the powder component to the liquid polymer and stir until a smooth and homogenous slurry, is achieved.
• Allow the mixed slurry to stand for 5 – 10 minutes before use.
• Do not dilute with water.

Application:

• All vertical up-stands & junctions /corners are provided with 45° fillet with MorcemSeal Todo 1 all around the periphery of the junction. Substrate must be in a "Saturated Surface Dry" (SSD) condition (damp, without standing water) prior to application.
• The surface of application must be pre-wetted thoroughly with water and brought to a touch dry state. Take up the first coat application with a stiff nylon brush/roller. Work well into the substrate, to ensure that all small undulations are completely filled with the coating.
• Provide and lay 45 GSM glass fibre mesh over the angle fillet when the first coat in still wet.
• Corner Joint Tape and Pipe collars embedded between the 2 coats.
• 6 to 8 hrs after completion of first coat, take up second coat application in a direction perpendicular to the first.
• Complete the application and leave to air cure for 3-5 days. A moist hessian cloth can be kept over the coated surface to protect it from the effect of direct sunlight, in case of bathrooms and internal areas, leave the coating for air curing for 3-5 days at least.
• For vertical walls in bathroom ensure internal plaster is sound and levelled.
• Apply 2 coats of MorcemDry F on all over shower area. Allow it to cure for atleast 5 days before going for tile application.
• When applied in swimming pool :
  • Apply MorcemDry F in 2 coats with each coat perpendicular direction to previous applied at the 6-8 hours interval at 1.6 Kg/m2/coat coverage.
  • Whilst first coat is still wet embed 145gsm alkali resistant glass fiber mesh and then apply 2nd coat of MorcemDry F at recommended coverage.
  • Extend the coating up to the full height of internal RCC walls. After curing direct tile application can be done with tile adhesive.

Curing:

• Protect against wind, sun, and sun during hardening. To prevent excessive drying, it is advisable to cover the surface with damp sackcloth or plastic during the curing process.

Recommendations

• Do not add water or dilute MorcemDry F during application.
• Do not do part mixing, mix complete pack.
• MorcemDry F needs at least 3-5 days for curing.
• Do not cure by flooding with water or conduct any ponding test before it gets completely cured.
• Concrete & masonry surfaces must be cured for 28 days before application.
• Overlay of a cementitious screed must be done within 24 to 48 hrs after curing.
• Additionally, for Bathrooms/Wet areas etc. The waterproofing coating should be done on levelled surface. For the application over brick/block/RCC walls, refer detailed application methodology.
• Avoid application under the risk of frost, rain, heavy wind, or direct sun light, or either cover it. 
• Consult with the Technical Department for any application not specified in this Technical Data Sheet. For any information regarding safety in handling, transportation, storage, and use of the product, please refer to the label and the updated version of the product's Safety Data Sheet.

The information and instructions in this datasheet are based on our current tests and technical knowledge. They are intended as general guidance and do not constitute a binding commitment by PIDILITEPUMA MEA CHEMICALS LLC. It is the sole responsibility of the user to verify, prior to use, that the product is suitable for the intended application and to ensure that it is applied correctly and in accordance with applicable regulations and good industry practice.

PIDILITEPUMA MEA CHEMICALS LLC cannot control how its products are applied on site throughout the entire project and therefore cannot accept responsibility for their application by contractors or other parties involved in the execution of the work. Support visits to the jobsite by our technical staff do not change that. Our responsibility is limited exclusively to defects that can be directly attributed to the supplied products, whether used individually or as part of a system, caused by manufacturing defects.

It is the responsibility of the project designer, site manager, contractor, or other relevant professionals to ensure that the selected products are appropriate for the specific project, taking into account their properties, the substrate, site conditions, and any existing issues.

In the event of a claim, the original packaging must be provided to ensure proper product traceability.

Any performance values stated for PIDILITEPUMA MEA CHEMICALS LLC products or construction solutions, whether in UNE standards or other applicable standards, are based solely on the specific test conditions defined in those standards (such as substrate type, temperature, and humidity).
