DURALiTe®D50 white cement-based fi nishing plaster is a durable external and internal fi nishing compound for walls. DURALiTe®D50 is designed to be applied over new or existing sand cement plasters – scratched, smooth or rough wall fi nishes, or painted surfaces, to create a silky-smooth appearance. DURALiTe®D50 will not swell or soften when it gets wet, as it is cement based. DURALiTe®D50 can be sandpapered.
NOTE: For both external as well as internal application. The surface must be hard, sound, dry and free of dust, dirt and other materials such as old gypsum plasters, grease, oil or any other contaminant.
DURALiTe®D50 OVER PREVIOUSLY PAINTED SURFACES:
All previously painted surfaces must be cleaned properly by means of high-pressure washer (externally) or scraper and brush/wire brush on internal surfaces. Remove all loose/flaky paint off the wall. Once cleaned apply DURALiTe®D50 straight over in the manner set out under section 1.4 APPLICATION. Where enamel and epoxy paints are used prime with iTe SLURRY Keying Promoter prior to application of DURALiTe®D50.
DURALiTe®D50 OVER NEW OR EXISTING SAND CEMENT PLASTERED WALLS: The plaster must be fully cured before applying DURALiTe®D50. Scrape/Brush off any loose debris off the wall. Slightly wet the wall to prevent instant water absorption out of the DURALiTe®D50. DURALiTe®D50 is then applied in two coats, first one being a scraper coat and allowed to dry. The second finishing layer is applied at 3mm thickness.
DURALiTe®D50 OVER CONCRETE SURFACES:
It is of the utmost importance to remove all releasing oils or grease from the concrete before applying DURALiTe®D50, by degreasing the surfaces with degreasing soap and rinsing afterwards with water. Once this is done prime the surface with iTe SLURRY Keying Promoter.
DURALiTe®D50 OVER GYPSUM – OR FIBRE CEMENT BOARD:
Use joining tape or fine wire mesh over butt joints. Apply DURALiTe®D50 over the joint allowing it to semi-set up. Once this has occurred apply a 3mm DURALiTe®D50 layer over the entire surface to achieve a smooth and even finish.
Use 14.0 litres of water per 35 kg or 4 litres per 10 kg bag. Do NOT over-water. Add the powder to the required amount of clean cool water in a clean mixing container whilst using an electric paddle mixer until a lump-free plaster is produced. This will take approximately 3 minutes. Stop the mixer and scrape the inside of the mixing vessel to allow any unmixed product to fall onto the paste. Allow product to slake for 5 minutes. Briefly remix the DURALiTe®D50 and then plaster onto the desired surface.
Mixed DURALiTe®D50 should be applied within 30 minutes at 20˚C after mixed. This time is extended at lower temperatures and reduced at higher temperatures.
DURALiTe®D50 can be applied over existing paint, sand cement plaster, concrete, fibre cement as well as gypsum boards. The following application method is used once preparation is complete. (see 1.2 Surface Preparation for different surfaces):
Apply DURALiTe®D50 with a trowel in an even and smooth manner, covering the entire surface area. Allow DURALiTe®D50 set up – test by touching the surface, if no indent shows and no product is set on your hand it is ready to be floated. Wetting the surface slightly with a plaster brush, use a rubber float to flatten area and bring fine material to the surface. Strike off excess fines with a steel float and smooth off the surface. Allow surface to harden then polish with a steel float.
Flash-off/set up time can take longer/shorter depending on weather conditions. It is also affected by the porosity of the surface onto which DURALiTe®D50 is applied.
Recommended thickness ranges from 3mm to 10 mm thickness.
Approximately 1.4 kg of DURALiTe®D50 per 3 mm thickness per m². E.g. one 35kg bag of DURALiTe®D50 will give enough material to cover approximately 25m² at an average thickness of 3mm. NOTE: The coverage figure is based on a relatively flat surface. Additional material should be allowed for where the surface is rough or uneven.
All data given was tested at a room temperature of 20˚C and 50% humidity. Please be aware that the technical data may alter if the climatic conditions are in contrast to that in which the product has been tested, either hardening more quickly or setting slower.
