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. It can be used to protect unpainted mineral plasters, such as Lime Green Solo, to give enhanced water repellency to external renders or limewash and to protect breathable floors or bare bricks walls. Other porous mineral surfaces such as cement or stone are also suitable, after trials to check compatibility. Silguard is highly breathable and will not trap moisture vapour.
Unsuitable backgrounds include dolomitic limestone, gypsum or related materials, walls or floors with salt contamination, retaining walls or walls with a hydrostatic head of water.
Colour Clear and matt; minimal change in appearance for most surfaces. Test before full application.
