Silguard is a powerful, highly breathable treatment designed for lime and other mineral backgrounds. Silguard reduces water penetration and surface dusting, making it the ideal alternative to acrylic sealers for a wide range of lime plasters, renders, floors and related materials. Silguard contains waterglass and siloxane to harden slightly dusty surfaces and make them water repellent. This enables it to be used to protect unpainted mineral plasters, such as Lime Green Solo, to give enhanced water repellence to external renders or limewash and to protect breathable floors. Other porous mineral surfaces such as cement are also suitable, after trials to check compatibility. Silic8 Silguard is highly breathable and will not trap moisture vapour. Unsuitable backgrounds for Silguard water repellent treatment include bare masonary, gypsum or related materials, walls with salt contamination, retaining walls or walls with a hydrostatic head of water damaged or cracked render and plaster
