Applied on interior facades, our multipurpose single component insulation coating is a Sustainable, A1 / Class 1 Fire, Water, Sound, and Thermal Resistant Material, having a High Diffusion characteristics (Breathability), available in white or grey color. LAVACOAT Interior Coating insulates and protects buildings from heat, sound, water & fire using a proprietary blend of inorganic natural aggregates.

LAVACOAT Insulated Interior Coating is applied directly on interior building walls, (concrete, masonry, brick, aerated concrete, pumice brick). Can be applied in the same manner as stucco or plaster, and many types of decorative finishes can be achieved. LAVACOAT Insulated Interior Coating can be used in new construction and renovation of existing buildings for the purpose of improving the water resistance and insulation values. *NOTE: Cannot be applied directly onto Metal, Wood, Concrete or Drywall, without using LAVACOAT Metal / Wood / Concrete / Drywall Primer.

Pour each bag of LAVACOAT Insulated Interior Coating into a clean vessel or commercial grade concrete/stucco/plaster mixer. (Water requirements may vary depending upon the type of mixing equipment used).
  • Mixing using a HAND-HELD mixer; Use between MIN 15 - MAX 17 Liters (MIN 4 - MAX 4.5 Gallons) of water, and mix for 6-7 minutes at low or medium speed.
  • Mixing using a COMMERCIAL GRADE CONCRETE, STUCCO, PLASTER mixer; Use between MIN 16 - MAX 18 Liters (MIN 4.25 - MAX 4.75 Gallons) of water, and mix for 6-7 minutes at regular mixer speed.
  • It is recommended that the mixture should be left to stand for 2 - 3 minutes after mixing.
  • The final consistency, after proper mixing, will result in the fully mixed product FALLING or DROPPING OFF THE TROWEL- SLOWLY.

    The surface of application area must be free from dust, dirt, oils, surface contaminants, etc. NOTE: The application is applied in the same method as stucco or plaster.For a single coat application, it is recommended to use minimum 1.5 cm [5/8 inch) thickness. For TWO coat applications, after applying the rough coat and left to dry for 6-12 hrs, apply a thin layer max 5 mm (3/16 inch] top coat. All types of decorative surfaces can be achieved with appropriate tools (float, trowel, sponge, etc) for the top coat. Leave to dry for 24-48 hrs.

    • The content of a bag of LAVACOAT Insulated Interior Coating MUST be used completely once the bag is opened.

    • The product must be mixed with a handheld or concrete mixer (for minimum 6 minutes) at LOW revolution.

    • If the mixture prepared (MAX. 1 hour) sits too long in the vessel and loses its consistency, you must NOT add water. Consistency can be renewed only by mixing with a low revolution mixer.

    • To apply LAVACOAT Insulated Interior Coating over painted surfaces, mineral plaster and other coatings, purge the surface approximately at a rate of 70% by using paint remover chemicals, surface abrasion or other similar methods.

    • Can be painted after 48 hours using ONLY water based and/or Acrylic paints.

    • During the mixing process, the person mixing the LAVACOAT product must wear a pair of safety glasses or goggles and a mask for health and safety purposes. See MSDS for additional precautions.
