SME-PS (polystyrene) is a Soy-Based Concrete Penetrant which, when applied, absorbs deep into the concrete pores to repel water and salt and extend the life of concrete. Coverage rate of 130 square feet per gallon - applied with a brush, roller or sprayer. One coat with thorough coverage is recommended and reapplication is recommended every 7 to 10 years. Will have a "wet concrete" look after application, but it dries clear.
Warning: Can be removed from skin with soap and water. Avoid prolonged or repeated contact with skin as it may cause dryness or irritation. Avoid contact with eyes. If contact does occur, rinse material from eyes and (if possible) remove contacts immediately. If symptoms persist, see a doctor. Heavy exposure can soften asphalt materials. Acrylic or other polymer-based products can prevent sealant absorption or react chemically with Sustain Krete.
