LD730
Acrylic Sealant

LD730 Acrylic Sealant is a one component, gun grade acrylic sealant with fungicide, designed to provide a flexible paintable seal where shrinkage and construction tolerances have left unsightly gaps in building interiors.

Usage/Purpose

LD730 is a flexible, mould resistant acrylic sealant for use in painting and decorating. It provides an over-paintable seal for filling cracks and gaps around door and window frames, penetrations, damaged plaster and other wall and ceiling surfaces.

  • Ideal for filling and sealing small cracks and gaps throughout building interiors
  • Over-paintable: will overcoat with a wide range of paints
  • Solvent free: no unpleasant solvent odours
  • Contains fungicide to prevent mould growth

Usage Guidelines

  •  The user is advised to conduct tests to determine the suitability of the product for the intended application prior to use
  • Application should be in accordance with BS 8000:16 - “Code of practice for sealing joints in buildings using sealants”.
  • Apply with conventional skeleton gun at temperatures between +5°C and +40°C.
  • All beads should be tooled after application to ensure full firm contact with the joint faces.
  • LD730 can be over painted with emulsion paint after approximately 1 hour. Allow 3 - 4 days with oil based paints depending on ambient conditions.
  • Protect from water for a minimum of 24 hours after application.
  • Application in damp or humid conditions will significantly extend the cure time.
