Installation Techniques

Consult a 3M Authorized Fire Protection Products Distributor or Sales Representative for applicable UL,

ULC, Intertek or other third-party drawings and system details.

For a typical mat installation, the following tools may be of assistance: razor knife or

large scissors (to cut mat), T-Square or similar straight edge (to help with straight

cuts of mat), tape measure (to measure mat required), marking pen (to identify layers

of mat), 3M™ Aluminum Foil Tape 425 (to seal cut edges of mat), rubber roller (to

ensure good adhesion of tape), Scotch® Filament Tape 898 (to temporarily hold

mat pieces in place - optional), stainless steel bands 1/2 in. wide x .020 in. min thick

(12.7 mm x .5 mm) and band clips or stainless steel tie wire to help secure mat, band

tensioners, 3M™ Fire Barrier Sealant CP 25WB+ (where required).

Determine the appropriate number of layers required for your application. Ensure

proper covering and protection of joints, seams, overlaps and any area that requires

special cutting and fitting. Ensure proper use of banding to mechanically restrain the

mat system. Refer to listed system details for sealant, securement requirements,

layer requirements and other installation procedures.

Maintenance

No maintenance is expected to be required when installed in accordance with listed

system details. Once installed, if any section of the 3M™ Interam™ Mat I-10/I-10A

damaged, the following procedure will apply: for damage to the outer metallic

covering, install 3M™ Aluminum Foil Tape 425 to overlap a min. 2" (50.8 mm) in all

directions. For more extensive damage (including damage to the mat material),

contact 3M Fire Protection Products at 1-800-328-1687.
