Superseal 25™ is a high performance, MS polymer, moisture curing sealant. Superseal 25™ is a low modulus product which makes it ideal for use in situations that may experience significant expansion and contraction.
Not recommended for: some porous stone materials, swimming pools or hot tubs, glazing, bituminous surfaces. Pre-test adhesion on painted or coated surfaces.
All surfaces must be clean, dry, sound and free from dust, oil, old sealant or other contamination. For best results wipe all surfaces with Isopropyl Alcohol (IPA), using a lint free cloth. Adhesion to metals can be further improved by light sanding.
Application: Mask either side of joint to produce a neat finish. Cut tip off cartridge, fit nozzle, load into H.B. Fuller caulking gun and trim nozzle to desired size.
Gently squeeze trigger to dispense and push sealant into joint to ensure complete filling. Within 5 minutes of application, finish surface with wet spatula or other smooth implement. Remove any masking tape before the sealant skins.
