THERMO-LAG 3000 APPLICATION PROCEDURES
THERMO-LAG 3000 shall be applied in good weather, following good painting practices. In
general, the substrate and ambient temperature shall be no less than 41°F (5°C), and 5°F
(3°C) above dew point. Humidity shall not exceed 85%. Any deviation shall be subject to
approval by CARBOLINE. All attempts shall be made to maintain dry conditions throughout
the application process, through the topcoat application.
The Applicator shall apply THERMO-LAG 3000 over a properly cured approved primer. The
material shall be applied in 40 – 120 mil (1mm – 3mm) passes. Apply as many passes
required to provide the desired film thickness. Lighter coats will provide an improved surface
appearance. Allow applied material to cure sufficiently to support the weight of subsequent
coats. The thickness which can be applied in a single coat will depend on the temperature,
humidity, applicator technique, etc. The time between coats is largely dependent upon
ambient temperatures and in general the following table should be used:

If the overcoat time has been exceeded, the surface of the THERMO-LAG 3000 must be
reactivated as described below:
The actual production work must follow, and conform to the approved finish / surface quality
established by the site sample. The site sample is a mandatory requirement and should be
kept available for all parties to have access to throughout completion of the project.
If required, contact Carboline’s Fireproofing Technical Service Group for further assistance
with finishing techniques.
Greater than 72 hours but less than 7 days
THERMO-LAG 3000 must be solvent wiped with Toluene or Plasite Thinner #19 to
reactivate the surface and remove contaminants.
