Heavy Duty Reinforced Acrylic Waterproofing Coating for TerraceDubond's Roof Shield is a heavy duty terrace waterproofing system, composed of specially developed highly elastic & resilient acrylic polymers, properly selected & graded fillers, lightfast & weather durable pigments, micro-fibres, additives & best quality fungicidal in water medium. it is used as a liquid applied waterproofing membrane for all types of building terraces. Dubond's Roof Shield is a three-layer system with coats in different colours ensuring proper build-up of the thickness, making it a reliable waterproofing system.

Areas of Application

• Building roofs / terraces – flat & slope.
• Over existing cementitious waterproofing treatments like brick-bat coba, concrete screeds, acrylic coatings, etc.

Method of Application

• Surface Preparation Prepare the surface thoroughly by cleaning, washing and removing dust, dirt, oil, grease and loose particles. Ensure that the roof slope is a minimum of 1 in 100.
• In existing old terraces such as brick-bat-coba or screeds, the substrate must be checked for its soundness. Damaged or hollow portions, sharp edges, etc. must be cut and repaired with a polymer-modified screed. Surface cracks must be filled with Dubond's acrylic crack filler.
• Bitumen based waterproofing treatments must be completely removed by mechanical scarification or by any other effective mechanical means.

Application

• Apply one coat of Dubond's Hydro Prime without any dilution at the rate of 10-12 m per litre. allow it to dry for 2-3 hours.
• 2 Apply the first coat of Dubond's Roof shield at the rate of 2 m per litre and allow it to dry before taking up the second and third coats, the rate of application being the same.
• The sequence of colours viz-a-viz, green or terracota grey can be decided depending on the desired top coat colour.
• In case only two colours are being used, ensure that the colour of the first and the third coat are the same. this would ensure correct consumption of material that will deliver a total Dft of 1 mm.
• Drying time between coats will be 6 to 8 hours.
• Ensure that the primer and the 3 coats of Dubond's Roof Shield totally achieve a minimum thickness of 1 mm Dft.
• allow the system to air cure for 7 days minimum.

Precautions & Limitations

• All corners, gaps, joints, protrusions & outlets shall be coated with two extra coats.
• Do not apply during rains; substrate Must be in SSD condition for application of primer.
• the product is designed only for foot traffic and not vehicular or movement of machinery or equipments.
• Note : To achieve the full proof waterproofing, parapet walls must be covered with Dubond’s Rainshield.

Health & Safety Precautions

• Skin contact : Wash skin with soap & water. Remove contaminated clothes.
• On eye contact : Immediately splash eyes with plenty of water. Consult Physician if irritation persists.
• Ingestion : Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a Physician.

Hydro Epoxy is a thixotropic, epoxy paste system, that  complies  with the  performance  requirements for structural bonding.

Areas of Application

• For structural bonding between pre-fabricated concrete structures and reinforced or pre-stressed concrete elements For structural bonding of steel plates and pultruded composite plates to reinforced and pre-stressed concrete
• For waterproofing inside the watertanks where hydrostatic / negative preassure exists.

Features & Benefits

• Eco-friendly
• Excellent adhesion to concrete, steel and composite materials
• Organic mineral adhesive for the structural bonding of concrete, steel and composite material elements Resistant to environmental chemical aggression and suitable for all exposure.
• Safeguards the health of operators.

Method of application :

Structural bonding of prefabricated concrete structures to reinforced and prestressed concrete elements, and of steel slabs , pultruded plates and composite fabrics to reinforced and prestressed concrete elements Surface filling of cracks prior to injection of fluid mortars for structural consolidation

PreparationHydro Epoxy is prepared by mixing component A with component B (preset ratio 1 : 1 in the buckets) until a soft paste of uniform colour is obtained. Mix by hand or using a low-rev, mechanical stirring device. Workability timesmay vary according to the density of the mixed paste and the temperature of the environment and substrate: the higher the temperature or the larger the mixture, the lower the workability time.

Application

• Before applying Hydro Epoxy first brush or preferably sandblast the concrete substrate to roughen and clean it, removing any remaining dust, grease, oil or other contaminants until the substrate is clean and cohesive.
• Once all rust, oil and paint has been removed, metal surfaces must be prepared to standard by first manually cleaning them or by mechanical cleaning (sandblasting) Hydro Epoxy is applied with a spreader.
• We recommend spreading Hydro Epoxy on both surfaces to be bonded, making sure the product penetrates well in more uneven parts of the substrate.
• To strengthen cracked structures by first opening the crack using a flexible joint, removing any dust under pressure into previously drilled injection holes. Subsequently, the crack can be filled with Hydro Epoxy through injection tubes inserted into the same holes as before.

Precautions & Limitations :

• Use at temperatures between +5 °C and +30 °C Apply on dry substrates
• Do not apply to dirty or flaking surfaces
• Protect surrounding surfaces from accidental smearing and staining, which would be difficult to remove clean tools immediately after use with solvents (ethyl alcohol, toluene, xylene)
