It is not necessary for the floor to be completely dry prior to the application of epoxy matrix, however, no free water should be left on the surface. .4 Existing concrete surfaces to be cleaned to remove all sealers, waxes, dirt, oil, adhesives, grease, etc. utilizing a caustic soda wash followed by a thorough rinse. Grind surfaces with a 24 grit Carborundum stone, followed by a thorough sweeping to remove all loose grit, followed with a thorough wash.

3.3 TERRAZZO METAL DIVISION STRIPS .1 All strips shall be in as long lengths as practicable. .2 Dividing strips shall be provided throughout all terrazzo work to form squares or rectangles. Furnish and install metal division strips at junction of terrazzo borders and other flooring materials. Include for stripping in squares not less than four lin. ft. and not more than nine square feet in area. .3 Strips shall be in long, straight lengths with joints only where necessary inserted in the fill before the concrete sub-bed has set or to existing structural slab with epoxy bonding..4 Provide metal division strips at junction of terrazzo finish and other floor finishes and if such occurs at a door opening, division strips shall occur under door. .5 Install terrazzo expansion joint strips in locations shown on the drawings or maximum 36 o/c each way.

3.4 APPLICATION OF MONOBOND TERRAZZO .1 Monobond is a two-component system. The Monobond should be stirred to disperse any settled ingredients. The curing agent (hardener) is then added to the Monobond and mixed thoroughly in the recommended ratio as it appears on the label. Monobond should be mixed in quantities that will be applied in approximately 4 hours.

.1 The mixed Monobond is quite fluid and may be applied by spray, stiff brush or steel trowel. The spray application is most practical for a large area. If a low pressure garden type spray is used it may be necessary to thin the adhesive by adding a maximum of 1 pint of Acetone to 1 gallon of mixed Monobond. (Thinning ratio 1 part solvent to 8 parts adhesive). For brush or trowel application do not thin, simply pour monobond on floor and spread.

.1 Coverages are as follows: .2 Imperial Gallons: 150-200 sq. ft. per gallon .3 Application over very rough or irregular surfaces will reduce coverage. .4 The Monobond should be allowed to dry until it is no longer wet but still tacky. This will take approximately 1 hour, depending upon the temperature. The material will remain tacky for approximately 4 hours. .5 Prior to placing the terrazzo mix, it is suggested that the floor be "seeded" or sprinkled with dry marble chips. These chips will allow tradesmen to walk on the floor without coming into contact with the Monobond, and will also result in a better mechanical bond of the mix. .6 The terrazzo mix is then poured over the Monobond while it is still tacky.

Note: Care must be taken that the Monobond has not lost its tack before applying the terrazzo mix. If Monobond loses its tack, it is necessary to apply another coat.

.7 The above application procedures are based on an average room temperature of 70 F. Lower temperatures will result in longer setting cycles; higher temperatures will shorten the cycle. The terrazzo is installed using standard mixes and conventional procedures.

.2 CURING AND FINISHING .1 After the terrazzo has taken its initial set and as soon as conditions permit, the surface should be coated with "Curite", manufactured by MacNaughton-Brooks to allow a slow and proper cure, and to protect against staining. As an alternative to this method proper curing can be attained by thoroughly wetting the surface with clean water and then covering with polyethylene sheeting. .2 After a few days of protected curing the terrazzo is then ground, grouted and finished using conventional methods.

.3 GENERAL NOTES (HANDLING & CLEANING)

.1 Normal precautions must be taken when handling the curing agent or mixed Monobond, to avoid contact with the skin. (The use of rubber gloves is recommended.) Monobond can be removed from the skin with soap and water if washed immediately but becomes increasingly difficult to remove when allowed to dry. The use of solvents such as Acetone, Toluol, etc. will assist the cleaning up operation. .2 Proper ventilation should be supplied during the installation and signs should be posted indicating that sparks or open flames in the area are not permissible. .3 Monobond becomes slightly thicker when cold and should be stored and applied at normal room temperatures.

.4 GRINDING .1 After the terrazzo has set sufficiently hard the surface shall be rubbed by machine using a No. 24 grit or finer abrasive block. Use plenty of water during grinding. Immediately following initial grinding, flush terrazzo surfaces thoroughly using water only and apply grout to fill all voids. Mix grouts in the same proportions as used in topping. .2 Allow grouted surface to cure for at least 48 hours and then re-surface by machine rubbing using No. 120 grit abrasive blocks and plenty of water. .3 Following removal of grout scrub terrazzo thoroughly using machine scrubbers and ample clean water. Rinse terrazzo with clean water and then dry thoroughly. Apply coat of sealer soon after cleaning as possible.

3.5 TERRAZZO SEALER .1 Application shall be in strict accordance with the manufacturer's printed instructions. .2 Clean and wash finished terrazzo as recommended in the Maintenance Guide of the Terrazzo, Tile & Marble Association of Canada for this type of terrazzo application. .3 Floors to receive sealer and two coats of finish.

3.6 CLEAN UP .1 Before final acceptance of the work all damaged work of this sub-division shall be made good, joints re-pointed as required, protection removed and the entire work cleaned and in an approved manner so that it shall be turned over in perfect condition in all respects. .2 Remove all debris and excess material not required by the contract promptly from site.

SECTION 09500ACOUSTICAL TREATMENT

IntroductionThe selection and specification of acoustic ceiling systems should be based on a careful analysis of functional,aesthetic, and cost criteria. Fire resistance, sound absorption, noise reduction, durability, and appearance considerations will combine to narrow selection choices to a range of a few acceptable alternatives, so that cost may serve as a final determinant to list of two or three acceptable products for bid. Ideally the specification should be performance-based, but it is in the Universitys best interest in acoustical ceiling s to inform bidders through semi-proprietary specifications which describe essential characteristics and name a selection of 3 or more products by different manufacturers which the Consultant has determined meet the functional and aesthetic requirements. Acoustic ceiling material specifications should list required type, form, pattern, noise reduction coefficient or articulation class, ceiling sound transmission class, light reduction coefficient, flame spread, fire resistance classification, and sanitation. On projects with unique requirements, such as performing theater or auditorium, a special acoustic consultant should be considered to advise the Consultant in the design of the space as well as the acoustic materials of the spaces.

Part 1 General

Ceilings in general areas (offices, corridors, public spaces) should generally be 2 x 4 square-edged lay-inpanels. Ceilings utilizing a 2 X 2 grid and/or regular tile may also be considered if approved by the Project Manager. Entry lobbies and conference rooms may use tile and grids with more design oriented features.
