ARDEX S 4
Green Slab Seal
ARDEX S 4 is a water based liquid solution designed to penetrate deeply into the concrete slab reducing the risk of moisture related problems.
ARDEX S 4 can be applied to green concrete slabs where it will penetrate deeply into the slab and react with the free lime forming a hardened gel substance; filling pores, voids, hairline cracks and trapped air cells, creating a permanent slab seal against moisture.
Installation: • ARDEX S 4 is applied using a backpack low pressure sprayer for small to medium jobs
• For larger projects an airless HVLP sprayer can be used
• It is important that the treated surface is sanded and vacuumed after 24 hours from application
• Refer to the product data sheet, or contact ARDEX technical services
