RainGuard Pro Micro-Seal Densifier LS is an easy-to-use alternative to sodium or potassium silicates, and does not generate hazardous wastewater. It is a high-quality densifier, hardener, and sealer for concrete surfaces. The lithium silicate (LS) penetrates deeper than potassium and sodium silicates and is much less likely to blush. When a concrete surface is densified, the harder surface helps make cleaning and surface maintenance easier and provides a dustproof finish. RainGuard Pro Micro-Seal Densifier LS will not contribute to surface Alkali Silicate Reaction (ASR). Ideal for use on freshly placed, steel troweled, uncured, ground/honed, polished, and/or green concrete surfaces.
