Sikalastic 624 WP waterproofing system is a liquid applied alkaline-resistant single component saturating resin with fiberglass or polyester reinforcement
Sikalastic 624 WP Waterproofing System may only be used by experienced professionals. Sikalastic waterproofing systems, including Sikalastic Plaza Deck/PMA and vegetated systems for both new construction and refurbishment . It helps in split-slab waterproofing - between slabs, vegetated deck waterproofing, plaza decks with concrete pavers, and asphalt or concrete paving stones in a sand bed. It allows waterproofing under tile in a mortar bed and works with cementitious and asphalt pavement overlays with waterproofing around/beneath mechanical equipment.
Sikalastic 624 WP Waterproofing System combine a cold applied, aliphatic, single component, alkali resistant, moisture-triggered polyurethane resin with fiberglass mat or polyester fleece reinforcement to create a seamless membrane and flashing system. It is often used as a separate wearing course (overlayment or overburden), but Sikalastic 624 WP Waterproofing System is UV resistant without protection board and is therefore suitable for direct exposure waterproofing tasks as well.
