Waterproof Permanent Gap & Seam Filler

Aquabond’s Waterproof Permanent Seam and Gap Fillers for swimming pools and spas are professional swimming pool sealants specially engineered to work like silicone caulk but with a huge added advantage – permanent clarity and flexibility!

Both ABC-9100-300 (Clear) and ABW-9000-300 (White) provide a permanent solution for glass and acrylic bonding, work on stainless steel, and also bond to aluminum, wood, masonry, ceramics, plexiglass, fiberglass and vinyl – even under wet conditions!

High viscosity and non-sag, these excellent pool sealants “stay put” even on vertical surfaces. Easy to dispense with with our 26:1 ratio caulking gun, they can be applied in temperatures as low as 32 degrees F, and skin over in under five minutes. They’re also UV resistant and available in your choice of CLEAR (ABC-9100-300) or WHITE (ABW-9000-300) to make color matching unnecessary.


  • Use in wet or dry environments including swimming pools, spas, standing water on concrete and other trouble spots
  • Use on glass and acrylic panels or glass blocks to make a non-structural watertight seal
  • Use to seal stainless steel pools and pool gutters
  • Use between pool tile and bond beam trim as a permanently waterproof, flexible gap filler
  • Use to seal the gap between a concrete pool bottom and the vinyl liner or poly panels
  • Can be used as an expansion joint filler and sealer
  • Use for any DWV (drainage, waste or vent) application
  • Not for use in high pressure applications
  • Since this is a solvent based product, proper ventilation is required when applying

Key Features:

  • Perfect for use on vertical, horizontal or sloping surfaces
  • Contains UV inhibitors for above water applications

Application Tip:

Use a peeled potato as an applicator!

Dispense the sealer between the peeled potato and the crack or joint and run the potato along the joint line. By doing this you’ll achieve a perfectly smooth finish in a single pass.
