SKETCH 2A-Fireproofing Patches APPLICATION GUIDE CAFCO FIBER-PATCH / ISOLATEK® Type P The applicator shall completely and fully read and understand the Long Form Application & Installation Manuals for the specific CAFCO® Spray-Applied Fire Resistive Materials (SFRMs) being used in conjunction with CAFCO FIBER-PATCH (ISOLATEK Type P) prior to applying this product. CAFCO FIBER-PATCH (ISOLATEK Type P) is a versatile, hand applied fire protection material designed for patching damaged CAFCO spray-applied fire resistive materials. CAFCO FIBER-PATCH (ISOLATEK Type P) is easy to use and requires no special equipment. It is classified by Underwriters Laboratories, Inc. in all UL designs listing CAFCO BLAZE-SHIELD DC/F (ISOLATEK Type DC/F), BLAZE-SHIELD II (ISOLATEK Type II) and BLAZE-SHIELD HP (ISOLATEK Type HP) for areas up to 432 in.2 (0.3m2) and in UL designs listing CAFCO 300, 300ES, 300SB, or CAFCO 400, limited to a maximum area of 144 in.2 (0.1m2). DIRECT HAND APPLICATION SINGLE COMPONENT MIX UL APPROVED ECONOMICAL AND EASY TO APPLY NONCOMBUSTIBLE MIXER RECOMMENDATIONS: 6 ft3 (170 liter) capacity paddle type plaster mixer with rubber tipped blades. Mixer should operate at approximately 40 RPM and should be clean prior to mixing. MIX TIME: Approximately 3 minutes until a plastic consistency is achieved. WATER REQUIREMENTS: 5 to 5.5 U.S. gallons (19 to 21 liters) of potable water per bag. HAND MIXING: FIBER-PATCH may also be mixed manually with a mason’s hoe or trowel in a large bucket as follows: Add one quart (1 liter) of water to one pound (0.5 Kg) of product. Mix by hand or trowel in a 5 gallon (19 liter) bucket or other suitable container for 3 to 5 minutes until a plastic consistency is achieved. TOOLS/ACCESSORIES: As required for specific application but may consist of plastic pails or buckets, hawk, trowel, mason’s hoe, stepladders, garden hose etc. Ensure surfaces are clean and free of dirt, oil , grease, loose mill scale, paints/primers (other than those approved), loose or poorly adhered fire protection material and any other materials that may impair adhesion. Prewet the steel and surrounding fire protection material with water prior to applying CAFCO FIBER-PATCH (ISOLATEK Type P). APPLICATION TEMPERATURE: Maintain a minimum substrate and ambient temperature of 40°F (4°C) prior to, during and a minimum of 24 hours after application. VENTILATION: Provide a minimum of 4 complete air exchanges per hour until the material is dry. APPLICATION TECHNIQUES: Apply CAFCO FIBER-PATCH (ISOLATEK Type P) in multiple layers until the patch is at the required thickness as indicated in the applicable UL design.

Owner is responsible for providing fuel. Schedule must include shutdowns to properly coordinate with CU Emergency Generator crew. 2 Please provide Elevator Dimensions and Weight Rating.The elevator weight rating to be 4500lbs, must be in freight mode. Equipment Information - Total Opening - 9, Openings (Frt/Rear) - 9F, Dover, MRS-11, 2010. 3 Number of wall penetrations required?Please refer to drawing E-102 for details. Additionally, any required penetration through wall with "Vermiculite" notification must be coordinated with Owner in advance at a minimun of two (2) weeks. 4 Please provide Number of Floors between the Basement & Penthouse for the Fire Alarm Riser Conduit. See Addendum No. 1, Item 2. 5 Please provide Specified product required for Sprayed on Fireproofing Patches. See Addendum No. 1, Items 3 and 4. 6 Based on the Specification 284621.11, 2.3 the releasing Control unit should be provided thru the Fire Alarm Vendor. It this the intent or should this unit be provided by the Sprinkler Vendor? Please provide specified unit if the sprinkler vendor is to provide. This is to be provided by fire protection vendor. Coordination between the two vendors will be necessary. 7 1. Is the Releasing Control Panel and related releasing system peripheral devices noted on contract drawing F-601 and Specification Section 284621.11 intended to be of the same manufacture as the new E3 Series fire control panel and to be provided by the fire alarm equipment supplier or is it a separate system provided by the fire protection contractor? 2. The fire alarm symbol list shown on F-001 calls for fire alarm horn/strobes. We believe the Rhodes Hall building utilizes all speaker/strobe appliances. Can you please confirm which is correct and if speaker/strobes, is their adequate capacity in the existing system to accommodate the NAC appliance additions? The existing system amplifiers are no longer manufactured or supported. 1) The releasing panel and associated releasing system devices are intended to be of a manufacturer compatible with the new E3 Series control panel. 2) The current devices located within the energy storage system room are horn/strobe appliances, therefore horn/strobes shall be used to replace them.
