Application steps

SUBSTRATE PREPARATION

  • Before applying EPS insulation board, attach BMI Mesh from the edges of all planned termination points of the insulation with base coat.
  • This strip of mesh will wrap the edge of the insulation when the base coat is applied “back wrapping”.
  • The EPS insulation must be well fastened or adhered to the substrate.
  • If insulation board has been adhesively applied, wait at least 24 hours before continuing work on the surface.
  • Fill 1/8” (3.2 mm) gaps and larger in insulation board with slivers of EPS.
  • Cut slivers flush with razor blade and rasp entire surface of insulation board.
  • EPS insulation board shall not vary more than 1/8” (3.2 mm) in every 8’ (2.4 m) span.
  • Cut any aesthetic joints at this time.
  • Brush or blow off all insulation dust from wall.
  • To complete the back wrapping of the insulation board, apply the base coat to the underside and approximately 6” (15.2 cm) up the insulation board.
  • Starting from the underside, trowel in the BMI Mesh fully into the base coat.
  • Do not leave any wrinkles in the mesh.
  • Feather the base coat onto the insulation board.
