Specifications include, but are not limited to: 1. Perform work of this Section by material manufacturer's approved applicator in strict conformance with manufacturer's printed instructions, or perform such operations under direct supervision of qualified representative of material manufacturer. Successful Contractor shall submit evidence of the manufacturer’s approval within (10) days of submitting its bid and prior to executing a contract. 2. All windows and panels on building “B” shall receive new sealant. 3. Specific windows and panels on building “A” (approximately 32) shall receive new sealant. Some sections will require sealant at cracks in plaster. See ATTACHMENT for photos of specific locations. 4. Applicator shall examine all surfaces and report to the General Contractor all conditions not acceptable. 5. Thoroughly clean all joints, removing all foreign matter such as dust, oil, grease, water, surface dirt, frost and old caulking materials. Sealant must be applied to the base surface. Previously applied paint or primer must be entirely removed. 6. Porous materials such as concrete masonry or stone shall be cleaned where necessary by grinding, blast-cleaning, mechanical abrading, acid washing or combination of these methods to provide a clean, sound base surface for sealant adhesion. 7. Laitance shall be removed by acid washing, grinding, or mechanical abrading. Form oils shall be removed by blast-cleaning. 8. Loose particles present or resulting from grinding, abrading or blast-cleaning shall be removed by blowing out joints with oil-free compressed air (or vacuuming) prior to application of primer or sealant. 9. Non-porous surfaces, such as metal and glass, shall be cleaned either mechanically or chemically. Protective coatings such as methacrylate lacquer on metallic surfaces shall be removed by a solvent that leaves no residue. Solvent shall be used with a clean cloth or lint less paper towels. Do not allow solvent to air dry without wiping. Wipe dry with clean, dry cloth, or lint less paper towels. 10. Joint areas to be protected with masking tape or strippable films shall be cleaned before application of tape or film. 11. Prior to purchase or delivery of materials, the contractor shall submit a shop drawing indicating all the necessary components for each type of joint to be sealed. 12. All joints to receive sealant shall be as indicated in the product Data and Shop Drawings submittals. Do not seal joints until they are in compliance with manufacturer’s recommendation and are acceptable to the Owner. 13. The contractor shall submit technical data on all materials proposed to use from the manufacturers. 14. The contractor shall submit color samples for review and approval by the Owner. 15. The contractor shall prepare a mock-up of all window and panel types once the Product Data and Shop Drawings submittals have been approved by Owner. 16. Joints to receive sealant, back-up material or pre-formed joint filler shall be cleaned out, raked to full width and depth as required by Applicator. 17. Joints shall be of sufficient width and depth to accommodate specified back-up material or preformed joint filler and sealant. 18. Install back-up material or joint filler, of type and size at proper depth to provide sealant per manufacturer’s recommendation. Back-up material shall be of suitable size and shape; and compressed to fit joints as required by the manufacturer’s printed instructions. Sealant shall not be applied without back-up material and/or bond breaker strip. When using back-up tubes avoid lengthwise stretching. Tube or rod shall not be twisted or braided. 19. Apply masking tape, where required, in continuous strips in alignment with joint edge. 20. Prime surfaces, where required, with primer as recommended by sealant manufacturer. 21. Follow sealant manufacturer's instruction regarding mixing (if required), surface preparation, priming, and application procedure. 22. Apply sealant under pressure with hand or power actuated gun or other appropriate means. Gun shall have nozzle of proper size and provide sufficient pressure to completely fill joints as designed. All joint surfaces shall be tooled to provide the contour as recommended by the manufacturer. When tooling joints, use tooling solution recommended by manufacturer. Remove masking tape immediately after joints have been tooled. 23. For sealant application when air temperature is below forty degrees (40o) Fahrenheit (four degrees (4o) Centigrade), consult sealant manufacturer for recommendations. 24. Clean adjacent surfaces of sealant as work progresses. Use solvent or cleaning agent as recommended by sealant manufacturer. All finished work shall be left in a neat, clean condition. 25. The sealant joints shall be uniformly smooth, free of wrinkles, flush with adjacent surfaces and absolutely watertight. Adjacent surfaces which have been soiled by the application of the sealing compound shall be wiped clean and be left neat. 26. The work will be judged defective due to the sealant's hardening, cracking, crumbling, melting, shrinking, leaking, or running
