Details

Sikalastic 624 Liquid applied alkaline-resistant single component saturating resin with fiberglass or polyester reinforcement

 

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.

Sikalastic®-624 WP: Resin used for all systems with Sika Reemat or Sika Fleece reinforcements
