Grouting or groutingcompound is often used for sealing teak decks. Depending on the manufacturer, sealingcompound is available in black, white and grey, in cartridges or tubes. Before applying Pantera'sgroutingcompound on wooden surfaces or when using Sikaflex sealant, a suitable activator or primer must first be used, depending on the surface. No primer is required for Tikal products. We recommend our Tikal Sealant Joint Tool Kit for finishing sealant joints.
