LIGHTWEIGHT CEMENTITIOUS FIREPROOFING EXECUTION

4.1

Application Steel surfaces shall be primed with a primer in accord with the fireproofing manufacturer’s requirements. Fireproofing shall be installed in a way that prevents the ingress of moisture between the f ire resistant coating and the protected structure or equipment. Appropriate reinforcement (such as metal lath or wire mesh), as recommended by Manufacturer, shall be applied per fireproofing manufacturer’s guidelines to strengthen fire resistant coverings. Fire resistant coverings shall be a pplied in accordance with manufacturer’s recommendations.

4.2

Surface Preparation Bare carbon steel has been cleaned and primed by others in accordance with Painting Specification BGS-MX-001. Damaged and bare areas of shop-primed steel have been cleaned and touched up by Others in accordance with above specification after erection.

4.3

Reinforcement Application

4.3.1

Equipment Skirts Wire mesh reinforcement shall be installed around the complete profile of the skirt. Mesh shall be fixed at approximately 16-inch centres using reinforcing spacers. It is important that the mesh is not hard up against the substrate, but is pulled away to lie in the middle third of the total thickness being applied. In areas where stud welding is not permitted, wire mesh reinforcing may be wrapped around the steel section after the first coat of material has been applied. Mesh shall be overlapped a minimum of 2 inches at all joints and shall be securely wire tied. No more than three mesh thicknesses are permitted at any one joint. Note: On small diameter skirts, chair bars shall be installed vertically. It may be necessary to space the chair bars more closely together so that the minimum-maximum spacing of the reinforcing from the skirt is maintained. When protection is required on the interior of skirts, reinforcing shall be installed in a similar manner.

Control joints shall be installed in the fire protection of all skirts. The control joints shall be Plastic Nosed Corner Bead installed vertically from top to bottom, wire tied to the reinforcing mesh at 6-inch centres. Control joints shall be spaced as follows:

4.3.2

a.

Skirts 5 feet to 10 feet in diameter shall have joints installed at the quarter points of the circumference. Skirts less than five feet in diameter shall have two joints 1 80 degrees apart.

b.

Skirts with diameter greater than ten feet shall have joints eight feet (plus or minus one foot) spaced evenly about the circumference.

Columns and Beams (Contour Design) Weld pins on 16-inch centres. Install wire mesh around the complete profile of the protected area. Mesh shall be overlapped a minimum of 2 inches at all joints. Galvanized or zinc coated steel clips shall be used to hold the mesh in place. It is important that the mesh is not hard up against the substrate, but is pulled away to lie in the middle t hird of the total thickness being supplied.

4.3.3

Columns and Beams (Box Design) Metal lath shall be formed around the structural member in a boxed configuration, overlapped 2 inches and secured every 14 inches with tie wire. When w eb depths exceed 12 inches, stainless steel bands shall be installed under the metal lath to provide support. The bands shall be wrapped around the structural member placed no more than 14 inches apart. The metal lath shall be tied to the bands with tie wire. The lath may also be secured with studwelded or gunned pins. The lath must be taut across the web span. Plastic nosed corner bead shall be placed on the corners of structural members and be firmly secured to the metal lath using tie wire.

4.4

Coating Application

4.4.1

Mixing Applicator Material shall be mixed in a mechanical mixer with paddle or ribbon-type blades. The mixer shall be clean and free of previously used and set materials. Mixing shall be in accordance with the material Manufacturer’s instructions. Partially set, frozen, or lumpy material shall not be used. In all cases, over mixing of the material shall be avoided. Re-tempering is not permitted.

4.4.2

Applicator Material shall be spray applied utilising a progressive cavity-type pump equipped with an air compressor capable of delivering 9 cfm of air at 40 psi at the nozzle. Apply material in two coats of equal thickness. each coat shall be a minimum of ¼ inch thick. The surface of the finish coat shall be steel troweled immediately after spraying. In place dry density shall be 40 pcf (min) and 55 pcf (max). The first coat shall completely fill all space between the reinforcing and the surface of the item being protected. Honeycombing or any other type of void is not permitted.

4.4.3

Miscellaneous When areas to be protected are greater than those, which can be covered in two hours, the work shall be divided into segments of workable size. In all cases, the work shall start at the lowest point of the item and progress upward. When joining fresh material-to-material that has already set, the edge of the existing shall be slightly undercut to provide a good mechanical key. All material which has been in place longer than two hours, and to which additional material is to be applied, shall be dampened just prior to application of the new material. However, no free water shall be standing on the surface. Care shall be taken to assure full coverage at corners, openings, and all other such locations. When it is necessary to discontinue the work, such as at the end of a work period, exposed areas of the first coat shall be lightly scarified to provide a mechanical bond for the second coat. In such cases, the first coat shall extend ahead of the finish coat so that “cold” joints in finish coat do not occur directly over the joint in the first coat.

4.5

Curing Under normal temperature and humidity conditions is not required. However, in hot, dry and/or windy weather, damp curing shall be maintained for a minimum period of four hours. Immediately after placing, cover material with polyethylene film or wet burlap and keep damp for the duration of the curing period. Where ambient temperature is 50°F (10°C) or lower, or if the coating could be exposed to rain within 24 hours after placing, it shall be protected with polyethylene film. In hot weather, the set is greatly accelerated, therefore, when work under such conditions is contemplated, the Manufacturer’s recommendations shall be followed for setting time, working time, etc. In normal weather (75°F = 24°C) the pot life of this material is about one ho ur. Joints and points of termination shall be caulked with appropriate material.

4.6

Weather Barrier Lightweight cementitious formulations shall be designed for exterior service without a topcoat.
