Poroparge is a high performance modern parge coat that has been specifically designed and tested for fast application onto Porotherm Poroton clay blocks. Engineered to increase air tightness and to optimise the sound performance of Porotherm clay block walls, prior to dry lining. Poroparge has been designed to be applied by brush or roller ensuring fast de-skilled application.
The weather conditions for application and drying are critical. Do not apply if frost is forecast, in wet conditions when RH is above 85%, in temperatures below
+5ºC or above +30ºC, and for a min of 24hr after application. Do not apply to elevations in direct sunlight, or to substrates which are hot or below +5ºC. The render must be protected against any rain, direct sun or wind in the first 24 hours after application.
Coverage: Approximately 15-20sqm/bag. Please note, coverage depends on thickness. These estimates take no account of wastage.
