ISS Silicone Sealer

ISS is an environmentally friendly, penetrating, silicone sealer for concrete that offers incredible water repellency without leaving surface film, sheen or gloss. It is completely invisible when dry - concrete surfaces look untreated and completely natural. ISS is water-based, low-VOC and breathable. Its unique properties keep water out while allowing trapped moisture to escape. It reduces the chances of efflorescence, staining, and spalling and protects against freeze-thaw cycles. ISS is ready-to-use; simply apply with an ordinary low-pressure garden sprayer.

For indoor or outdoor use. Ideal for vertical surfaces. Not intended for use on areas subject to traffic.
