Sealer keeps water out

Okon W-1 Water Repellent Sealer lessens environmental erosion like dusting, chalking, cracking and spalling. When applied as directed, Okon W-1 will not change the natural appearance of concrete, masonry, stucco or plaster and can be used under or over painted surfaces.

The product is designed as a one-coat system that effectively seals concrete and masonry surfaces, preventing damaging moisture penetration that can cause problems such as efflorescence, freeze-thaw damage and staining.

The application of Okon W-1 Water Repellent Sealer to traditional plaster and diamond finish plaster leaves interior walls with a sealed, natural finish. The “rag-on, rag-off” application process provides the walls with a protective coating on these hard, steel-trowelled plaster surfaces, while maintaining their original beauty and color.

Okon W-1 Water Repellent Sealer is a 5-percent solids water-based premium sealer. VOC emission is well below the limits established for water repellents by the EPA and the state of California. For more information, visit or call (303) 377-7800.
