The surface shall be cleaned thoroughly of all contaminants like dust, rust, traces of curing compound, oil and grease. Where moss or lichen is present, remove sheets. Cut and reseal blisters in asphalt or roofing. Old concrete and steel must be structurally sound prior to application. Light mechanical grinding/grit blasting/high pressure water jet may be used to clean the surface of all the contaminants depending on the degree of contamination on the surface to be coated.

Complies with the specification requirement of ASTM D2939 |
20 litres pail & 200 litres drum | Dark brown (liquid) Black (dry) | Typical coverage rate of 3 to 5m²/ liter depending on density, surface porosity, surface profile, variations in level or wastage etc. |
Typical Applications
- General damp-proofing of concrete, asbestos cement sheets, roofing felts, wood etc.
- Protective coating for cladding works to prevent infiltration of vapour and moisture into the building structure.
Benefits
- Single component, solvent free
- Cold applied, no heating required
- Suitable for new and old concrete
- High rubber content - 5 %
- Reduced chloride penetration
- Vapour permeable allows substrate to breathe
- Resistant against chloride and sulphate ions.
- Non- slumping
- Easy application due to paintable consistency
- Environmentally friendly. Low VOC.
- Seamless/joint free
- Has good adhesion to most building substrates
The drum should be rolled on the ground back and forth before decanting material. Stir the contents of the drum thoroughly prior to application
The application can be done with a roller, brush or airless spray. Two or more coats must be applied to ensure a durable finish. Apply the coating at a coverage rate of 1 to 4 m²/ litre /coat, depending on the dry film thickness required. On vertical areas, it is recommended to apply the coating in multiple layers in order to avoid sagging of the heavy bodied coating. Subsequent coats shall be applied only after the previous coat dries off completely and shall be applied at right angles to the previous coat. Clean dry sand may be broadcasted onto the wet coating to provide a key for the subsequent coats and achieve a greater dry film thickness. Care shall be taken to ensure that the first coat is not punctured during the application of the second coat. However, if the coating is damaged, the area can be readily over coated provided the surface preparation is done properly.
AquaShieldPro RBE 3505 may be applied to damp but not wet surfaces, dampen brushes before and occasionally during use to avoid clogging and ease application. During hot, dry weather application may be assisted by dampening the surfaces to be treated.
Cleaning:
Clean all tools immediately after use with clean water. Hardened material can be cleaned with a solvent.
Protection:
Protect floors to withstand light foot traffic for at least 24 hours after installation. Stepping boards may be used after 24 hours when occasional stepping on the floor is unavoidable.
