Sika Sikasil Pool

Sikasil Pool Features

Sikasil Pool is a one-component, neutral-cure silicone pool sealant designed specifically for swimming pools and permanently submerged areas. It offers excellent resistance to chlorinated water and common pool cleaning agents, with an anti-fungal formula that effectively prevents mould growth. The neutral cure formula is non-corrosive and suitable for multiple substrates.

• One-component, neutral-cure silicone pool sealant
• Excellent chlorine resistance — withstands chlorinated water and pool cleaners
• Excellent joint movement capability
• Outstanding anti-fungal performance
• High elasticity and flexibility
• Neutral cure, non-corrosive
• Very high elastic recovery
• Very short skin-over time
• Suitable for permanently submerged areas
• Good adhesion to tiles, concrete, glass, metals and many other substrates

Applications

• Swimming Pool Joints — expansion and connection joints inside and around pools
• Permanently Submerged Areas — sealing in areas with constant water contact
• Shower Rooms & Wet Areas — shower enclosures, changing rooms and wet environments
• Tile-to-Structure Joints — joints between tiles and concrete, glass or metal surfaces
• Indoor & Outdoor — suitable for both interior and exterior environments

Why Choose Sikasil Pool

Sikasil Pool is the go-to pool sealant — specifically engineered for long-term submerged environments with superior chlorine resistance and anti-fungal performance compared to general-purpose silicone sealants. Standard silicone sealants (such as Dowsil 791) are not designed for pool environments and may deteriorate with prolonged chlorinated water exposure. Sikasil Pool has a very fast skin-over time, helping to speed up project schedules. Its very high elastic recovery ensures joints return to their original shape even after prolonged submersion.
