LAVACOAT / TOP-COAT is an extra layer of protective coating that can be applied on to all stucco, concrete and plaster finishes. It is designed to give an extra layer of firm protection and a smooth finish. It is resistant to cracking, water, and heat. It is also permeable, enabling the prime and first coats to breath.

LAVACOAT / TOP-COAT is applied directly on exterior facades of buildings, (concrete, masonry, brick, aerated concrete, pumice brick). It can be applied in the same manner as stucco and many types of decorative finishes can be achieved. LAVACOAT / TOP-COAT can be used in new construction and renovation of existing buildings for the purpose of improving the water resistance and insulation values.

Pour each bag of LAVACOAT / TOP-COAT 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 7 - MAX 7.5 Liters (MIN 1.85 - MAX 2 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 7.5 - MAX 8 Liters (MIN 2 - MAX 2.1 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 a stucco. For TWO coat applications, after applying the scratch/rough coat and left to dry for 6-12 hrs, apply a thin layer max. 4 mm (0.16 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. PLEASE WATCH VIDEOS ON TO FIND OUT MORE.


    • The content of a bag of LAVACOAT / TOP-COAT 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 30 MIN) 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 / TOP-COAT 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.
