In general resilient floor finish material shall be provided in wet areas, wet strips to sinks, practical activity, science, art, technology, home economics, and early childhood centre activity areas. In general ceramic tiles shall be provided in toilets. Ensure that the surface is non-slip but can be easily cleaned. Provide one row of skirting tiles to walls. Circulation areas shall be in carpet or resilient finish depending on the situation. Consideration shall be given to the use of the area, whether it is integral with the learning areas, its relationship to external areas and acoustic requirements for noise reduction. . Welded sheet vinyl can be used in special situations such as toilet areas in facilities for students with severe and multiple disabilities and should be coved to walls. There are specialised floor surfaces required for drama spaces, activity halls, gymnasiums and dance studios. The project will identify the particular requirements. Minimise the number of different floor finishes in any building, REFER: S2.11.3 Sports and on any site, to simplify the maintenance requirements. finishes Maintenance instructions shall be provided to the site for the floor materials installed upon completion of the project. All floor finishes shall be easily cleanable without requiring specialised methods or equipment. Some Relevant Australian Standards for floor finishes are: - AS 1385 – Carpets. - AS/NZS 2455.1 – Underlays/Laying. - AS 2055.1 – Flexible Sheet. - AS 1884 (1985) - Floor Coverings, Resilient Sheet Laying and Maintenance. - AS/NZS 4586 (1999) - Slip Resistance Classification of New Pedestrian Surface Materials. - AS 1530.3 – 1989 Early Fire Hazard Properties. Floor finish materials shall be included in the building contract. Mats Floor mats shall be provided to the inside of external doors. Mats shall be removable to enable them to be cleaned, and from a suitable proprietary manufacturer. They shall be the full width of the door opening and at least 600mm deep, inset into carpet which has an appropriate ‘naplock’ edging (not a brass angle), or loose laid on resilient sheet floors. A non-slip backing is required to these mats. ___________________________________________________________________________________ _ These guidelines are DECS specific Compliance with BCA and Australian Standards is assumed. DECS Facilities Design Standards and Guidelines 2 The intent is for a ‘clean off zone’ of suitable material to cover at least two walking steps from the door. Matwells recessed into concrete slabs are not to be provided. 2.11 Floor Finishes (contd.) 2.11.1 Carpet General Medium strength colours with patterns (fleck or graphic) are preferred. (Light colours show marks and stains and dark colours show dust.) Specific Acceptable carpet materials are: - From 100% pure wool to 80% wool / 20% nylon blend, 1627grams per m2 (48oz), level loop pile. (Cut pile is not preferred due to its ‘tracking’). Carpet shall be rated as Commercial (not domestic) ‘Heavy Duty’ under the Carpet Institute’s ACCS grading scheme or Wools of New Zealand Fernmark scheme. - From 100% BCF Nylon, with a minimum solution dyed fibre content of 75%, minimum 950grams per m2 (28oz), interlocking level loop pile, or minimum 1085 grams per m2 (32oz) cut pile. Soil resisting fluorochemical treatment of fibre is required. Carpet shall be rated Contract Heavy Duty under the Carpet Institute’s ACCS grading scheme. Secondary backing shall be 100% synthetic. - Electrostatically flocked nylon on a PVC backing can be used in particular areas where heavy traffic and water are likely to be present. Carpet shall comply with the current BCA requirements for fire resistance and fire hazard properties. Underlay shall be provided in the following situations: - Junior primary and primary general learning areas and withdrawal rooms where students spend time sitting on the floor. The preferred carpet in these situations is pure wool, wool/nylon blend, or nylon. - Where carpet is being laid over existing timber or uneven floor surfaces. - Where improved acoustic performance is required. The preferred underlay to wool and wool/nylon carpet is needled underfelt. The preferred underlay to level loop or cut pile nylon is a rubber underlay. The required underlay to electrostatically flocked nylon is a high density latex cushion type. The ‘double-bond’ method is preferred with underlays to avoid re-stretching carpet. Carpet shall be ‘direct stick’ to concrete floor slab elsewhere. Include naplock where carpet adjoins other floor finishes. Metal hammered naplock preferred. Skirtings to carpet areas shall be timber or flat vinyl. 2.11.2 Resilient materials General A strip of resilient floor material shall be provided in rooms adjacent sinks where carpet is the main floor covering. ___________________________________________________________________________________ _ These guidelines are DECS specific Compliance with BCA and Australian Standards is assumed. DECS Facilities Design Standards and Guidelines 3 A patterned finish and a medium colour is preferred to reduce marks being shown. 2.11 Floor Finishes (contd.) 2.11.2 Resilient materials (contd.) Specific Characteristics required of resilient floor finishes are as follows: - Minimum thickness of 2.0mm. - Homogenous material or inlaid pattern with a minimum wear layer thickness of 0.7mm. - The general cleaning regime shall require only sweeping, a damp mop and vacuum cleaner. - Spot cleaning as per manufacturers recommendations. - Slip resistance (wet and dry) to Australian Standards. - There shall be no requirement for sealing, waxing or polishing. - Resistant to staining and attack from chemicals. Where they meet the above requirements the following resilient finish materials are acceptable: - Vinyl floors - Rubber (100% synthetic, not natural rubber) - Electrostatically flocked nylon on a PVC backing. Generally sheet materials shall be used in preference to tiles. Skirtings to resilient sheet areas shall be feathered edge vinyl. DRY AREAS Dry areas are regarded as those that are unlikely to have significant quantities of liquids spilled on them, such as circulation, practical activity, and technology areas. In these areas a smooth resilient sheet is acceptable to meet the dry slip resistance requirements of AS/NZS 4586 – 1999. WET AREAS Wet areas are regarded as those that are likely to have significant quantities of liquids spilled on them, such as art, science, home economics and toilet areas. In these areas a slip resistant resilient sheet is required to meet the wet slip resistant requirements of AS/NZS 4586 – 1999. In rooms where wet areas may be confined to only part of the space, consideration can be given to providing a slip resistant resilient sheet strip to the floor of that part of the space. 2.11.3 Sports finishes General Specialised sports floor finishes shall be provided in primary school multipurpose general activity halls and secondary school gymnasiums. Sports floor finishes shall be included in the building contract, and include line marking to the range of games required. To protect the sports floor finish from dust and grit it is desirable to provide some floor finish to other adjoining rooms in the building, including stores. ___________________________________________________________________________________ _ These guidelines are DECS specific Compliance with BCA and Australian Standards is assumed. DECS Facilities Design Standards and Guidelines 4 Specific A range of sports floor finish materials are available and have been used in school activity halls and gymnasiums. Each product has particular characteristics, cost and maintenance implications. 2.11 Floor Finishes (contd.) 2.11.3 Sports finishes (contd.) The selection of the appropriate floor finish shall consider these criteria and the particular project requirements. The following are the most commonly installed sports finishes: TIMBER PARQUETRY This is the most common finish used, especially in primary school activity halls. A durable surface for a range of activities. The preferred finish is Monopack 3651 Sports Floor Finish. A urethane based clear gloss finish, it requires re-coating every 12 to 24 months depending on the extent of use. “GRANWOOD / GRANSPRUNG” A composite tile laid on a bedding screed on a concrete slab. Gransprung is the same tile material laid on a sprung sub-floor. The preferred finish is as per timber parquetry. “TARKETT MULTISPORT” Plywood panels laid on rubber pads and single timber joists on a concrete slab providing a sprung floor with some resilience. The surface can either be hardwood strips with an acrylic lacquer finish, or a fibreglass reinforced sheet vinyl on a foam backing. “TARKETT SPORT ELITE” Fibreglass reinforced sheet vinyl on a foam backing adhered directly to the concrete slab, without the resilient sub-floor. “REGUPOL” A composite flooring applied in layers on top of a concrete slab providing a resilient and uniform surface. The finished surface is a matt polyurethane layer. The lines are painted on before the final clear finish layer. “SYNPAVE REBOUND IMPACT” A composite flooring applied in layers on top of a concrete slab providing a resilient and uniform surface. The finished surface is either a water-based or solvent-borne urethane layer. The lines are painted on the top surface. “MONDOFLEX” A composite sheet material comprising natural and synthetic rubber providing a top wearing surface on a resilient supporting layer, adhered to a concrete slab. “MONDOSPORT” A composite sheet material comprising an embossed, compact PVC top layer and an expanded PVC supporting layer with fibreglass reinforcing, adhered to a concrete slab. ___________________________________________________________________________________ _ These guidelines are DECS specific Compliance with BCA and Australian Standards is assumed. DECS Facilities Design Standards and Guidelines 5 Line marking The preferred line marking methods for all sports floor finishes are a two-pack epoxy painted finish, or being inlaid into the flooring, depending on the material used. ___________________________________________________________________________________ _ These guidelines are DECS specific Compliance with BCA and Australian Standards is assumed.
