Rolled Hollow Section (RHS)
Tubular and other hollow steel sections are reinforced in a similar manner except that the
entire surface is reinforced by using one or two pieces of mesh. The mesh shall be
overlapped 1” (25mm) on all seams.
5.2
FINAL THERMO-LAG 3000 APPLICATION
After the mesh has been installed, apply THERMO-LAG 3000 to the final required thickness
in as many coats as is necessary. Any overcoating shall be done within 72 hours of the
prior coat. If the time is exceeded, the surface must be prepared as stated in Section 5.0
.
It is mandatory that imbedded mesh is covered with 40 mils (1 mm) of THERMO-LAG
3000 prior to daily shutdown
.
5.2.1 TERMINATION ONTO NON-FIREPROOFED STEEL
Where the THERMO-LAG 3000 terminates to non-fire protected steel, the THERMO-LAG
3000 shall be sprayed to the specified thickness for the given length and beveled on a 45°
angle down to the substrate. The top coat system shall continue down onto the no-
fireproofed substrate (minimum 1” or 50mm) to insure a proper seal.
5.3 FINAL THICKNESS
The final thickness shall be specified in project drawings and Owner specifications.
Thicknesses for THERMO-LAG 3000 are outlined in Intertek Design Nos. CC/BA 180-01,
CC/CA 180-02, CC/CA 180-03 and UL Design No. N608. All are based on average
thicknesses. However, on some projects, a minimum thickness may be specified from the
owner or specific engineering firm. When an average thickness is specified, the minimum
acceptable thickness for any one point shall not be less than 80% of the specified thickness.
The overall average thickness must be equal to or greater than the specified thickness. The
number of thickness checks and other issues regarding this topic are found in Technical
Manual 12-B and SSPC PA2.
All matters relating to the thickness(es) shall be decided
between the owner and the applicator prior to the startup of the job.
After THERMO-LAG 3000 has cured, an approved thickness gauge shall be used to ensure
the thickness requirements have been met. Thicknesses below specification shall be built
up to specified thickness by the application of additional THERMO-LAG 3000. An alternate
method of thickness measurement can be performed by drilling a pilot hole and using a
penetrating measuring device. It is required to fill all probe holes with THERMO-LAG 3000
after measurements have been taken.
5.4 SAMPLE INSTALLATION
Prior to actual production work, a sample test area shall be prepared following all specified
procedures and approved finish / surface quality. This sample must then be approved by
representatives of the owner, applicator, architect and any others having a vested interest in
the installation. The actual production work must follow, and conform to, the standards and
approved finish / surface quality of the site sample.
The site sample is a mandatory requirement and shall be made available to all parties
throughout the completion of the project.
5.5 EQUIPMENT CLEANUP / FLUSHING
Plural component equipment with hot water flush components must be flushed using 150˚F
(66˚C) water, minimum.
Plural component equipment with solvent flush components must be flushed with Toluene or
Plasite Thinner #19.
