Cleaning

Porcelain tiles are extremely resistant to staining due to the low porosity. Metz porcelain tiles are unaffected by all janitorial cleaning products even in concentrated form. Cleaning products containing acids, alkalis, bleaches, solvents can be used without concern for the tiles.

Metz strongly recommend that proprietary floor cleaners be used as these are specifically formulated with beneficial properties for this task.  General purpose detergents and other cleaning products may perform poorly and leave residues that can build up and trap dirt.

Slip resistant finishes can be as effectively cleaned as smooth surfaces, and with the correct tools just as easily.

Installing Large Format Tiles

Modern manufacturing techniques have allowed the production of large format porcelain tiles with a high degree of accuracy in size and shape. This has enabled tiles to very effectively mimic the appearance of other materials such as large stone slabs and timber planks.

Such products provide the benefits of porcelain tile performance and durability with almost all of the character of the original material.

Because all manufactured materials have a degree of tolerance in production, installation materials and systems have been developed to enable the best possible results to be achieved more easily.

Chemical Resistance

Chemical resistance is another critical requirement for a kitchen floor system, food residues can be extremely corrosive. Just ask any dentist! Chicken fats, certain oils and other products can have an adverse affect on even some epoxy grouts.  Metz only installs high performance chemical resistant epoxy grouts. Correct installation is just as important…once attack commences more and more residues are trapped in the weak spot accelerating the rate of corrosion.

Thickness

Kitchen tiles should be thick – heavy items dropped on a thin tile may break the tile. Twice the thickness typically equals four times the strength. Thinner tiles must be fully bedded with no voids under the tile…or they will definitely break upon impact.

During installation, working a tile (pushing it down) into the bedding forces the adhesive to rise up the joint space. Using for example a 6mm thin tile will leave only a mm or two for epoxy grout to protect the adhesive from chemical attack. Metz recommend a minimum 12mm thick tile be used for commercial kitchens. Metz can also offer 15mm and 20mm thick tiles.

Slip Resistance

Slip resistance is achieved by surface profile or surface texture, or a combination of both.

Metz experience based on our client’s advice is that flat surfaces incorporating a gritty texture perform the best for slip resistance in commercial kitchens.

Surface profile can be achieved by either raised protuberances or depressions on the surface (slate finish). Metz do not recommend profiled tiles for commercial kitchens  depressed surface “slate type” finishes as these tend to capture dirt and surfaces with raised profiles can perform poorly with wear.

Introduction

Tiles provide the best value whole of life solution, to commercial swimming pool finishes.  The durability and minimal maintenance of tiles provides the greatest advantages for indoor swimming centres  which essentially never close and can not afford the lost amenity and patronage from a shutdown.

Other finishes that require regular repairs, maintenance or replacement, may be suitable for lower patronage outdoor pools that close during winter months,  however even these will likely find long term benefit from a tiled pool.

To best achieve these benefits, only purpose made swimming pool tiles should be used.

Special Pieces

More than most other tiling applications , swimming pools benefit from a range of special production shapes and profiles. Metz offer long and short rounded edge nosings in smooth or antiskid, with flat or ribbed profiles.  Also stocked are handhold / finger grip tiles, external radius pieces and internal cove pieces.

Metz stock a selection of colour combinations in these special ribbed edge nosings including possibilites for Ivory, White and Light Blue with either Dark Blue or Black edge strips.

Metz ribbed edge tiles incorporate a textured grip surface in addition to the ribbed profile, which provides greater slip resistance in all directions for this most critical area of use.

Slip Resistance

Slip resistance is achieved by surface profile or surface texture, or a combination of both.  Barefoot slip resistance benefits from both factors in combination, as the soles of feet can vary significantly in their thickness and rigidity from one individual to the next.

For the most critical applications such as pool edges, stairs, steps, raised starting platforms and hob surrounds Metz provide our unique combination of ribbed profile and texture to maximize slip resistance.

Metz recommend Barefoot C slip resistant surfaces for swimming pool and concourse applications, which is higher than the B recommendation in the slip resistance handbooks.  We are aware of a number of centres who advise that they are unhappy with the performance of their B rated tiles.

Colour Combinations

Metz can supply around 50 standard colours and carry stocks of white, dark blue, ivory and black  in both smooth and slip resistant surfaces. A further dozen or so colours are stocked in smooth glazes and when combined with Metz broad range of Stone, Modern, Timber and traditional styles offer the opportunity to create a distinctive facility for your clients.

Standards Australia Slip Resistance Handbooks

Standards Australia publish two slip resistance handbooks:-

  • HB197:1999     An Introductory Guide to the Slip Resistance of Pedestrian Surfaces
  • HB 198:2014    Guide to the Specification and Testing of  Slip Resistance of Pedestrian Surfaces

In the years following the publication of HB197, many designers and operators took the view that this was an optional guideline (not a standard) and that compliance was a choice.  Insurers quickly disagreed when courts were awarding significant payments to claimants in slip cases and in general settled claims where a design did not meet the minimum recommendations of this Handbook.

A number of strong criticisms emerged about aspects of the handbook, several were likely justified, however a number of problems arose simply because users did not familiarise themselves with some of the details and explanations that were within the pages.

Introduction – Which Test Should I Use ?

There are a number of different test methods recognised by the Australian Standard for slip resistance 4586:2013.  The most recognised is probably the ramp test with its R ratings  results  –  R9, R10 etc.

Metz recommend the Wet Pendulum Test as broadly being the most effective method, due mainly to the high likelihood of this test method being used to evaluate the suitability of a design selection after installation. The pendulum test is portable and therefore the test of choice for any forensic testing on site, which can be critical if there has been a slip incident.

Test results achieved by different test methods have no direct correlation.  Generally higher results achieved via one test method,  will typically achieve higher results on other tests.

A product that is believed suitable following one test type being carried out, may prove unsuitable following a different test type being conducted.

Wet Pendulum Test

The pendulum test apparatus measures  friction (CoF) and provides results as BPN (british pendulum number). The pendulum test is portable and therefore is frequently used on site as well as in laboratory conditions. It is one of the approved test methods under the Australian Standards AS4586 :2013  & AS4663:2013

The test has a number of advantages  over other test methods.

  • Portable and used for on site testing
  • The most likely test to be used in an investigation following a slip incident
  • Wet test using water – the most common contaminant
  • Consistent results with minimal operator impact
  • Used in conjunction with accelerated wear testing (AWT)

Wet Barefoot Ramp Test

Wet barefoot ramp slip resistance testing is used for applications where it is expected that the majority of users will be in bare feet.  This test is carried out on the same ramp apparatus as the oil ramp test except the test panel has a stream of water (no oil) and with the test operator not wearing any shoes.

As with the oil-wet ramp test, a panel of the tiles to be tested are inclined to the point where the barefoot operator slips, and the angle of the panel / ramp is measured.  The angle results are then classified as either A, B or C (highest).

Swimming pools, their surrounds and their amenities  are by far the most common design applications where wet barefoot test results are considered.  Metz extensive experience with swimming pools means that we will only recommend barefoot C rated tiles for pool surrounds.

Tortus – Dry Floor Friction Test

The Tortus test is conducted with a simple mechanical apparatus that measures the coefficient of friction (CoF) created between the tile and the device. The tortus test is conducted on clean dry surfaces only and results are classified as either D1  (if friction was > 0.4 Cof) or a D0  (if friction was > 0.4 Cof).

img

Oil/Wet Ramp Test

The Oil-wet Ramp Test (commonly referred to as just the “Ramp test”) provides scores that are widely recognised by most designers from their R – rating results  R9, R10 etc.  The mechanism of achieving these results however is often poorly understood, as are the limitations of this test method.  There are very significant limitations to the ramp test and the creation of designs and specifications using ramp test results alone has lead to many problems for designers, their clients and indeed users and operators of facilities.

An investigation of slip resistance following an accident will almost certainly not involve the ramp test results, but rather will consider on-site pendulum testing.  It therefore follows that to design a floor without knowledge of the pendulum results of the floor surface selected is a significant risk.

Displacement Volume Test

The Displacement Volume test essentially measures the amount of surface profile of the tile or flooring product. It is intended be an indicator for deliberately patterned products with raised dots, pyramids, squares, circles, ribs, ridges etc.  Flat textured surfaces will generally not achieve a result on this test however some extremely coarse textured surfaces of applied finishes may achieve a score in the lowest V4 category.

Ratings are  V4, V6, V8 or V10 (highest).

Profiled surfaces have generally received limited acceptance in the Australian market, and this limited acceptance has generally declined even further since the publication of HB198 in 2014.

The limitations of profiled surfaces include:-

Accelerated Wear Test

The 2013 version of the  Australian Standard 4586 now recommends the application of wear  to the items before  slip resistance testing,  where  there is a requirement for long term durability of slip resistance.

AWT (Accelerated Wear Testing)  provides an indication of how the slip resistance of an item will perform during long term use.  The most common wear application is 500 wear cycles (or scrubs) by the laboratory wear apparatus as shown. The application of 500 wear cycles is an excellent method of rejecting poorly performing products that loose too much of their initial slip resistance following installation and the initial handover period.

Application of 5,000 wear cycles is excellent for predicting
