Liquid membrane for waterproofing based on resins

Sikalastic®-220 W is a liquid, one-component, ready-to-use membrane, containing water-based resins, for the waterproofing of wet spaces. It provides a final layer fully bonded to the substrate, ready for the application of ceramic tiles. Thickness > 0.5 mm (0.0197 in). It will be applied to the interior.

Use
  • Waterproofing of shower cabins
  • Bathroom waterproofing
  • Waterproofing of walls and floors (medium-high degree of water and humidity in the upper rooms)
Advantages
  • Membrane without welds or overlaps
  • It is part of a complete system together with Sika® SealTape tapes, primers and adhesives for ceramic cladding
  • Monocomponent product, pre-dosed, ready to use
  • Water based
  • Quick drying
  • Water resistant
  • Good crack pick-up properties
  • It can be applied with a trowel or trowel
  • Application on various substrates: concrete, cement-based plaster, plasterboard, gypsum-based plaster, plaster-based masonry, dry screeds, old ceramic finishes (tiles, tiles, etc.)
  • In accordance with ETAG 022:1

Moisture content in the substrate

The Technical Data Sheet of the primer used will be consulted

Cementitious screeds must be at least 28 days old and residual moisture ≤ 2.0 CM-% and calcium sulfate screeds must have residual moisture ≤ 0.5 CM-%

Waiting Time / Recoating

Before applying the first coat or the second coat it will be expected:

~3 hours for walls

~5 hours for floors

Waiting times are approximate and may change depending on atmospheric conditions -temperature / relative humidity-.

Consumption

~ 1.35 kg/m² for 2 layers applied

SUPPORT QUALITY

The substrate must be clean and dry, free from contamination with dust, soil, grease, oil, cement milk, previous coatings or other types of surface treatments that could affect the adhesion of the new applied layer.

PREPARATION OF THE SUPPORT

Cementitious sub-layers shall be properly prepared using dry blasting / sanding / scarifying machines to remove cement laitance and obtain a rough, conforming texture for application of the product in the proper thickness.

Previous treatments or brittle areas will go away. Repairs / leveling will be done with products from the Sika range.

Dust, friable and non-adherent particles shall be removed prior to application of the product, preferably using a vacuum cleaner.

shuffle
  • Monocomponent, ready to use
  • It can be applied directly, without mixing
CLEANING OF TOOLS

Clean application tools and equipment with water immediately after use. Hardened material can only be removed mechanically.
