PRODUCT DESCRIPTION:

BASE COAT is a polymer modified, Portland Cement based product used to adhere expanded polystyrene insulation board to concrete and masonry surfaces and exterior grade plywood.  It is also ideal for embedding fiberglass reinforced mesh fabric, as well as providing an ideal waterproof base coat for synthetic stucco finishes and flexible insulation systems.

USES:

• Adhering polystyrene insulation board to concrete and masonry surfaces and exterior grade plywood
  
• Embedding fiberglass reinforced mesh fabric
  
• Waterproof base coat for synthetic stucco finishes and flexible insulation systems

• Provides increased impact resistance to insulation board
  
• Provides a crack resistant, non-brittle, waterproof coating
  
• Single component, just add water
  
• Resists wear and weathering
  
• Reduces need for control joints

Surface Preparation: 
Remove all loose concrete, grease, oil, paint, dust, form release agents or any other material that will inhibit proper bond.  If there is doubt that a good bond can be achieved, mechanical fasteners should be used to attach the insulation

board.  Recess heads of fasteners c" and cover with BASE COAT prior to application.  Scratch both sides of insulation board with rasp, wire brush or sawblade, making sure the shiny skin on board is broken.  The foundation wall must be damp when the board is placed.  Do not allow the wall to dry out.

Mixing: 
Each 50 pound bag of BASE COAT should be mixed with 12 gallons of clean water.  Add the powder to the water while mixing.  The use of a high torque, low speed drill (400-600 RPM) with a paddle attachment or a mortar type mixer with rotating, rubber edged blades is recommended.  Mix to a smooth, trowelable consistency and allow the mix to stand for 5 minutes.  Remix material, adding small amounts of water or BASE COAT to achieve the desired working consistency.  Do not use any additives.  Do not mix more material than can be applied in 1 hour.

Placement:      Adhering Insulation Board 
To attach the insulation board to the wall, apply material to the back of the board in mounds of at least 3" thick and 2" in diameter, making sure that material covers a minimum of 50% of the board.  An alternative method is to cover the entire back of the insulation board with BASE COAT using a d" notched trowel.  Place insulation board on wall and push firmly.  Using a block of wood, apply equal and even pressure to allow maximum bond to be achieved.  After adhering insulation board to the wall, wait 24 hours before coating the face of the insulation board.

Placement:                Embedding Fiberglass Reinforced Mesh Fabric 
Cut the mesh fabric into pieces that are manageable.  For lightweight to medium weight fabrics, allow for a 2" overlap.  Heavy mesh fabrics do not need to be overlapped, however care must be taken to butt the edges firmly together.  Apply a minimum of a 1/16" coat of BASE COAT to the insulation board and trowel in the mesh fabric, using a stainless steel trowel.  An alternative method would be to sandwich the mesh fabric between two 1/32" coats of BASE COAT.  Avoid trowel marks and ridges.  Be certain that no wrinkles or mesh fabric are visible through the BASE COAT.  If mesh pattern is visible, skim the area with a light coat of BASE COAT.

Placement:                                         Base Coat 
Using a flat stainless steel trowel, apply BASE COAT to entire face of insulation board to a uniform thickness of 3/32" to 3".

Curing: 
BASE COAT is self-curing.  Do not mist with water or damp cure.

Coverage: 
Each 50 pound bag will adhere approximately 50 square feet of insulation board or embed 100 square feet of mesh fabric.  As a base coat, each 50 pound bag will cover approximately 50 square feet of surface at c" thickness.

Packaging: 
Available in 50 pound multiwall paper bags with moisture barrier.

Color: 
Light gray
