General Application Procedure

Job Conditions – Follow directions on adhesive data sheets.  Mechanical attachment of insulation boards may be performed at lower temperatures over a dry surface.

Temporary Protection – Provide temporary and permanent protection to prevent water entry behind the system.

Substrate Preparation – Applications must be to an approved substrate with a maximum variation tolerance of 1/4 in in 10 ft (6.4 mm in 3.05m).  Contact Master Wall® for approved substrates and recommended attachment methods.

Application—The Insulation Board can be easily cut using handsaws, power saws, sharp knives, or thermal cutting tools. Rasping is completed with 12-grit sandpaper, either manually or with air or electric rasping machines.

Follow data sheet recommendations for adhering insulation board to approved substrates.  For mechanical attachment, fasten the Insulation Board to the approved substrate using Wind-Lock Wind-Devil 2 retainers.  See Master Wall® System Details for more information.  Fastening patterns shall be determined by the requirements of the geographical conditions of the area, local code requirements, and the performance of the fasteners and retainers, as well as their test results, in conjunction with the specified substrate and the thickness of MEPS specified for use.  Minimum 1 in (25.2 mm) thickness for mechanically attached systems.\Install insulation board on the wall according to specification requirements.  For further information and details, see the Master Wall® System Application Instructions.
