Installation Procedure

Examination

1. Substrate shall be of a type approved by of Exterior Precoated Foam Shapes’ manufacturer.
2. Substrate shall be dry and free of oil, dust, dirt, loose cement, moisture or any other non-cementitious surface contamination, and compatible with adhesive.
3. Substrate shall be free of planar irregularities greater than 6.4 mm (1/4 in.) in 3.0 m (10'0") and shall be sound and free of foreign substances.
4. Report unsatisfactory conditions to Contractor for correction by substrate installer before application of shapes.

Mixing

1. Adhesive and joint compound: Premixed as received from manufacturer in accordance with manufacturer’s written instructions prior to beginning application.

Preparation

Please Note: Confirm with Everest Mouldings & Specialities whether or not the Exterior Precoated Foam Shapes need to be backwrapped or not. This will depend on the installation method that would best suit the project.

Select a or b:

1. Exterior Precoated Foam Shapes Backwrapping Instructions:
   1. Peel mesh on back face of Exterior Precoated Foam Shapes along entire length and fold over on each side
   2. Extend above and below Exterior Precoated Foam Shape on to substrate.
2. Non-backwrapping installation procedure:
   1. Cut and remove mesh completely from back face of Exterior Precoated Foam Shapes along entire length.

Installation

Select a or b first, then continue:

1. If the Exterior Precoated Foam Shapes are not to be backwrapped, use the following installation procedure:
   1. Apply adhesive to entire back surface of Exterior Precoated Foam Shapes using a 9.5 mm (3/8") notched trowel.
   2. Immediately press into place Exterior Precoated Foam Shapes while adhesive is wet. Please Note: larger Exterior Precoated Foam Shapes require temporary support systems or mechanical fasteners until adhesive sets.
2. If the Exterior Precoated Foam Shapes are to be backwrapped, use the following installation procedure:
   1. Apply adhesive to entire back surface of Exterior Precoated Foam Shapes using a 9.5 mm (3/8") notched trowel.
   2. Immediately press into place Exterior Precoated Foam Shapes while adhesive is wet.
   3. Once Exterior Precoated Foam Shapes are in place, parge over the peeled fibre mesh with specified basecoat material to obtain a smooth, even finish.
   Please Note: Larger Exterior Precoated Foam Shapes require temporary support systems or mechanical fasteners until adhesive and basecoat sets.
   
   
3. Butt Joints between Exterior Precoated Foam Shapes:
   1. Apply adhesive to entire joint surface between Exterior Precoated Foam Shapes using a 9.5 mm (3/8") notched trowel.
   2. While adhesive is still wet, immediately butt together Exterior Precoated Foam Shapes to ensure a tight fit. Wipe away excess adhesive.
   3. Over the joint, apply a reinforcing mesh minimum 50 mm (2") on either side of the joint.
   4. Embed reinforcing mesh with specified basecoat.
   5. Feather out specified basecoat to obtain a smooth. even finish.
      
      
4. Corner Joints between Exterior Precoated Foam Shapes:
   1. Mitre joints for a proper, tight fit at a 45 degree angle.
   2. Apply adhesive to entire joint surface between Exterior Precoated Foam Shapes using a 9.5 mm (3/8") notched trowel.
   3. While adhesive is still wet, immediately butt together Exterior Precoated Foam Shapes to ensure a tight fit. Wipe away excess adhesive.
   4. Over the joint, apply a reinforcing mesh minimum 50 mm (2") on either side of the joint.
   5. Embed reinforcing mesh with specified basecoat. Feather out specified basecoat to obtain a smooth, even finish.
      
      
5. Finish Coating:

   Please Note: Confirm with Everest Mouldings & Specialities to ensure that the finish coating is compatible with Exterior Precoated Foam Shapes.

   1. After curing the Exterior Precoated Foam Shapes, remove temporary supports and fasteners and repair holes and marks in accordance with the manufacturer’s written instructions.
   2. Apply paint coat (primer and finish) over Exterior Precoated Foam Shapes in accordance with manufacturer's current finishing instructions.
