This system provides an economically lightweight and attractive finish to all makes and styles of ICF Block.

 
Rasp foam blocks to level surface.
 

ADVANTAGES

  • Flexible
  • Stain Resistant
  • Excellent Resistance to Freeze/Thaw
  • Water Resistant
  • Excellent Crack Resistance
  • Abrasion and Impact Resistant
  • Super Adhesion
  • Non Chalking
  • Wide Variety of Colors
 
Spray or trowel base coat onto ICF block.
 

SURFACE PREPARATIONS

Remove any dirt or other foreign materials from ICF Block surface prior to application or coating. Repair any large holes or divots in substrate before application of first coat.

 
Immediately embed glass mesh into base coat & trowel.
 

APPLICATION

MULTICOAT ICF STUCCO SYSTEM incorporates a BASE COAT of SCRATCH KOTE 2000 and a FINISH COAT of MULTI-TEX STUCCO MIX applied over properly prepared ICF Block.

BASE COAT of SCRATCH KOTE 2000 is field mixed with potable (clean) water to desired consistency and applied to surface. Mix vigorously to disperse all lumps and thoroughly wet all particles. Use margin trowel to clear vessel walls.

Embed and trowel Fiberglass Mesh into SCRATCH KOTE 2000. Cure a minimum of 12 hours before proceeding, longer in cold weather.

FINISH COAT of MULTI-TEX STUCCO is applied onto BASE COAT and textured to desired finish.

 
Apply Multi-Tex Stucco Finish & texture to desired finish.
 

COVERAGE

Each 65 lb bag of SCRATCH KOTE 2000 BASE COAT will cover approximately 80-120 sq. ft. Coverage may vary due to substrate conditions.

Each 5 gallon pail of MULTI-TEX STUCCO mix FINISH COAT will cover approx. 60-125 sq. ft.

Coverages will vary depending on porosity of substrate, texture of BASE COAT, and desired finish texture.
