PRODUCT DESCRIPTION

Underseal is a solvent-borne, alkali-resisting primer that seals and stabilizes new plaster, concrete, and other alkaline substrates to prevent paint failure. It provides a strong, stable foundation for subsequent coats of paint by neutralising alkaline activity on the surface and enhancing the bond between the substrate and the topcoat.

 

BENEFITS

  • Seals and stabilizes new plaster and concrete surfaces
  • Resists alkali migration that can cause paint failure
  • Enhances topcoat adhesion for a longer-lasting paint system
  • Good coverage for efficient material usage
  • Quick-drying to keep projects on schedule
  • Easy to apply by brush, roller, or spray

 

USES

  • Priming new plaster and concrete before painting
  • Sealing alkaline substrates on exterior surfaces
  • Plaster, cement, and brickwork surfaces
  • Block work, stone, and asbestos surfaces
  • New construction and renovation projects
