3 1. Product Description 3M TM FireDam TM Intumescent Coating WB 1000 is a single component water-based thin film coating to fireproof interior structural steel. 2. Instruction 3M TM FireDam TM Intumescent Coating WB 1000 for steel should be installed by trained and certified 3M authorized applicators. 3. Specifications 3M TM FireDam TM Intumescent Coating WB 1000 is listed by independent test agencies such as ULC and UL and is tested to, and passes the criteria of, Standard Fire Tests of Building Construction and Materials, CAN/ULC-S Edition (ANSI/UL TH Edition, ASTM E Edition). Typically Specified Division Division 7 Section Intumescent Fire Resistive Material Related Sections Section Structural Steel Section Structural steel and metal fabrications with reference to primer receiving fire protection materials Section Spray-Applied Fire Resistive Material Section Painting Fire Test Designs 3M TM FireDam TM Intumescent Coating WB 1000 was tested by ULC/UL on a large scope of columns, beams, floor assemblies and passed. Refer to the ULC/UL Directory for the 3M TM FireDam TM Intumescent Coating WB 1000 designs or please contact 3M. 3

4 4. Precautions & Limitations 3M TM FireDam TM Intumescent Coating WB 1000 for steel must be stored indoor in dry conditions between 10 C and 40 C. Protect from frost and freezing, excessive heat and strong radiant sunlight. Not intended for exterior applications. Comply with manufacturing recommendations for temperature and humidity conditions before, during and after installation of fireproofing. Refer to section 9. Application Rates & Conditions 5. Packaging & Shelf Life Packaging: Volume 18.9 liter (5 gal.) / Weight per pail: 61.6 Lbs (27.8 Kg) Shelf Life 3M TM FireDam TM Intumescent Coating WB 1000 shelf life is 6 months in original unopened containers from date of packaging when stored above 10 C (50 F). Lot numbering: First digit = last digit of year Second to fourth digit = 3 digit day of the year (from 001 to 365/366) Fifth indicator = dash symbol (-) Sixth to eighth = batch # (may only be 1 or 2 digits long) 6. Preparatory Work 3M TM FireDam TM Intumescent Coating WB 1000 for steel should be installed with an Airless spray pump such as Spraytech EP2355 or Graco 1595 / Ultra Max 795 or brush. All surfaces receiving the 3M TM FireDam TM Intumescent Coating WB 1000 for steel should be thoroughly cleaned of oil, grease, dirt, loose paint, loose mill scale and any other matter that will impair bond. Existing Conditions: (1) Verify existing conditions and substrates before starting work. Correct unsatisfactory conditions before proceeding. (2) Proceed with installation only after steel components are primed with compatible recommended primer. *Refer to section 8. Primers 7. Masking Provide masking and drop cloths to prevent contamination of adjacent surfaces by fireproofing material. 4

5 8. Primers General instructions for installing 3M TM FireDam TM Intumescent Coating WB 1000 for steel include confirmation of primer compatibility such as recommended Alkyd and Epoxy primers to receive 3M TM FireDam TM Intumescent Coating WB Note: Primers containing zinc metal are generally not recommended. Apply 3M TM FireDam TM Intumescent Coating WB 1000 only to primed surfaces. Site conditions and end-use may dictate specific primer specifications. Follow primer manufacturer s instructions. 9. Application Rates Refer to the 3M TM FireDam TM Intumescent Coating WB 1000 fire test design information to determine the minimum dry film thickness required for the size and orientation of steel element to be protected and for the required fire resistance rating. 3M TM FireDam TM Intumescent Coating WB 1000 should be applied in sufficient wet film thicknesses to achieve the required fire resistive rating with as many passes as necessary, to attain required (DFT) dry film thickness. 3M FireDam Intumescent Coating WB 1000 should not be applied when relative humidity exceeds 80% or the surface to be coated is less than 3 C above the dewpoint. The product is recommended to be applied only when temperatures are above 10 C or 50 F. To ensure an even coating thickness, the desired thickness should be achieved by the application of successive coats of no more than 500 microns dft (760 microns wft) per coat. Apply in sufficient thickness to achieve rating to uniform density and texture. The completed dry film thickness should be checked to ensure the required thickness has been applied. When multiple coats of 3M FireDam Intumescent Coating WB 1000 are required to achieve the prescribed dry film thickness, adequate drying time between the coats should be allowed. At 20 C the minimum overcoating time is typically 4-6 hours. (The time will vary depending upon the prevailing temperature, relative humidity, air movement and thickness of material applied). 5

7 11. Topcoats A compatible topcoat with 3M TM FireDam TM Intumescent Coating WB 1000 is recommended for all installations, in order to give the desired colour. All topcoats should be applied in accordance with the topcoat manufacturer s recommendations. Either acrylic or silicone alkyd paint to match surroundings are recommended. Ensure the 3M TM FireDam TM Intumescent Coating WB 1000 is thoroughly dry before application of topcoat. 12. Precautions & Safe Handling Information Follow approved working practices. Wear government approved respirators and proper clothing, reading all warning labels, and follow instruction on the MSDS. 13. Maintenance No maintenance is required when installed in accordance with the 3M installation manual. Once installed, if any section of the 3M TM FireDam TM Intumescent Coating WB 1000 is damaged, the damaged section should be repaired (touched up) by a 3M trained and certified applicator. 7
