Surface Preparation:

Surface must be clean, dry, sound and free of dust.
If any patches of oil are evident chip off all contaminated concrete or if that is not practical, use a powered floor cleaning compound. If the bond of the CROMPROOF Elastoseal HD to the substrate is critical as it is in roofing areas, reinforce membrane over contaminated area with COMPROOF Polyfab, a non-woven polyester fabric.
All metal surfaces to be coated with CROMPROOF Elastoseal HD must be free from grease, oils, dust and water. Remove grease and oils with a suitable degreaser, wash down surface with clean water and allow to dry.
Where movement is expected between elements, treat as an expansion joint with the use ofCOMPROOF Polyfab BB as a bond-breaker. Sharp corners, as between parapets and concrete deck, should be rounded by the placement of mastic at the corner.

Do not apply Elastoseal HD if the temperature is below 10oC, if humidity is above 80%, or if rain is imminent.
Temporarily protect the membrane from mechanical damage after application using polystyrene boards or an equally effective alternative.
A cement screed or topping may be laid over the system after 24 hours curing.
Externally where no toppingis intended, the system must be over coated with an U.V. stable acrylic coating.
