PART 3 EXECUTION
3.1
EXAMINATION
A. Do not begin installation until substrates have been properly prepared or environmental conditions are outside the Manufacturers absolute limits.
B. Examine for wet conditions; D not apply product to substrates that are wet or have been wet, unless they can be dried to the maximum moisture content as specified by the manufacturer.
C. Verify that substrates are ready to receive 1500 Seriesâ FireGuard E-84â thermal barrier coating.
D. Ensure that all primers are compatible with the coating.
E. Verify that items that need to penetrate the coating are in place, including clips, hangers, supports, and sleeves.
F. Verify that other work that would obstruct access to surfaces to be fireproofed has not been installed.
G. Where the thermal barrier coating is to be exposed to view as a finished surface, verify that surfaces are smooth, without voids, cracks, or projections.
H. If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.
3.2 PREPARATION
A. Clean surfaces thoroughly in accordance with manufacturer's instructions prior to installation.
B. Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.
C. Clean surfaces of dirt, dust, grease, oil, loose material, and other matter that may affect bond of the coating.
D. Protect floors and adjacent walls and ceilings from overspray, fall-out, and dusting.
3.3 INSTALLATION
A. Install in accordance with manufacturer's instructions.
B. Thoroughly mix product with a ½” electric or air driven drill with a slotted paddle or jiffy blade. Mix product for a minimum of 5 minutes to achieve the necessary texture required before application.
C. Install the thermal barrier coating by brush, roller or airless sprayer application. Multiple coats will be required to meet specifications to the job requirements. Allow each coat to completely dry to the touch before applying next coat.
D. Field tinting and thinning of product is not allowed.
E. Perform frequent measurements with a wet film gauge during each application to ensure uniform thickness and wet mil thickness as specified by the manufacturer.
F. Remove coating from surfaces not specifically required to be fireproofed.
3.4 FIELD QUALITY CONTROL
A. When required field inspection and testing will be performed by Owner's independent testing agency.
B. Correct defective work as a direct result from certified applicators installation and provide further inspection and testing to verify compliance, at no cost to Owner.
3.5 PROTECTION
A. Protect installed products until completion of project.
B. Remove excess material, overspray, droppings, and debris.
C. Touch-up, repair or replace damaged products before Substantial Completion. If thermal barrier coating becomes damaged rebuild required thickness by brush, roller or spray application. Damaged area must be abraded back to a firm edge by sanding or scraping. Topcoats should be abraded back 1” from the damaged area.
3.6 CONFORMANCE CERTIFICATION
A. Written Certification shall be provided for the substrates or assemblies treated for meeting the required code of the Authorities Having Jursidiction
