This is best achieved by lightly gritblasting the surface. Where moss, algae or similar growths have occurred, treatment with a proprietary biocide should be carried out after the grit-blasting process. Note: it is not necessary to remove Nitobond AR prior to the application of Dekguard E2000. Where application over existing sound coatings is required, trials should be conducted to ensure compatibility and retention of the bond between the underlying coating and the substrate. For further advice, consult your local Parchem sales office. It is essential to produce an unbroken coating of Dekguard E2000. To ensure this is achieved, surfaces containing blow-holes or similar areas of pitting should first be filled using Renderoc FC, a cementitious fairing coat (for further details, refer to separate Technical Data Sheet). Renderoc FC should be allowed to cure for approximately 48 hours, depending on ambient conditions, before the application of Dekguard E2000. Application In order to obtain the protective properties of the Dekguard E2000 system, it is important that the correct rates of application and overcoating times are observed. Nitoprime DG Dekguard Number of coats: Flood coat One Two Theoretical application Rate per coat: 0.4 litres/m² 0.4 L/m² 0.2 L/m² Theoretical wet film Thickness per N/A 200 400 coat (microns): Overcoating time (@ 20°C): 2 hours N/A 16 hours Application of Nitoprime DG should not commence if the temperature of the substrate is below 5°C. Application of Dekguard E2000 should not commence if the temperature of the substrate is below 5°C. Any areas of glass should be masked. Plants, grass, joint sealants, asphalt and bitumen-painted areas should be protected during application. Nitoprime DG should be applied first. It should be applied in one or more coats until the recommended application rate of 0.4 litre per square metre has been achieved. This is best
