APPLICATION

• Acoustic Screed Foam Pack can be used on pre-cast concrete plank floors that have a minimum mass of 300 kg/m2 with a ceiling type illustrated above
• New build
• Refurbishments
• Domestic upgrade

INSTALLATION

• The base floor must be swept and cleared of grit, loose stones and any objects that could penetrate the JCW Screed Foam resilient layer.
  
• JCW Screed Foam stretches slightly when rolled up. Screed Foam should be unrolled and allowed rest for a few hours before measuring & cutting. Cut the Screed Foam using a sharp knife and a straight edge.
• Secure the JCW Foam Flanking Strip to the perimeter edges allowing at least 50mm of foam to sit flat onto the base floor.
• Roll out the first length of Screed Foam along the base floor and over the top of the 50mm base foam flanking strip.
• Use 50mm wide Black Cloth Jointing Tape to continuously secure all edge joints.
• All subsequent layers of JCW Screed Foam must be overlapped by 50mm with all joints continuously secured using 50mm wide Black Cloth Jointing Tape.
• Sand and Cement screeds can now be laid directly on top of the Screed Foam. Screed depths of 65-75mm provides for a 25-35mm excess surface foam that can be later folded down onto the dry screed to isolate the skirting board from the screed surface.
• Proprietary and Anhydrite Screeds a 0.2mm waterproof membrane must be laid over the top of the Screed Foam and up all wall edges at least 50mm above the screed depth. The waterproof membrane must be overlapped by 100mm with all joints taped to prevent movement during the casting process.
• Screed Foam must be protected from other trades prior to the screed installation.
