Sika® Igasol® Emulsion BA

RUBBERIZED BITUMINOUS WATERPROOFING EMULSION

Sika® Igasol® Emulsion BA is a rubberized bituminous liquid emulsion with excellent adhesion, which dries to a tough, seamless, flexible, waterproof, protective coating and vapourproof membrane for concrete structures.
Suitable for use in hot and tropical climatic conditions.

Sika® Igasol® Emulsion BA provides:
  • High rubber content - 5 %
  • Excellent adhesion to most building substrates
  • Reduced chloride penetration
  • Can be applied on damp substrates
  • Non sagging
  • Single component
  • Water based
  • Economical, easy to apply, reduces labour cost
  • Can be applied on vertical and horizontal areas
  • Impermeable to water
  • Elastic, seamless, joint free
  • Unaffected by high ambient temperature
  • Resistant to aggressive soils and contaminated ground water
  • Low odour, dries without generating strong vapour

Application steps

SUBSTRATE PREPARATION

All surfaces must be sound, even, free from dust, loose particles and any contamination. May be applied to damp but not waterlogged surfaces.
Hot and very dry, porous concrete surfaces must be primed by diluting Sika® Igasol® Emulsion BA with clean water at 1 : 1 ratio (by weight).
When used as protective coating, all pinholes, cavities, cracks etc. in the substrate must be filled with a suitable Sika® repair mortar.

MIXING

Sika® Igasol® Emulsion BA must be stirred well before use. Where a single drum is used for prolonged periods, occasional stirring during application is recommended.

CLEANING OF EQUIPMENT

Clean all equipment and tools with water immediately after use. Dampen tools before and occasionally during use to avoid clogging and ease application.
