Care & Use of the Tate Access Floor System
Laminated with Unglazed Porcelain Tile
Access floor systems are supplied and installed in conformance with the requirements set forth by
individual project specifications and approved submittal documents. It is important to clearly
understand the design capabilities of the Tate access floor system as installed in specific projects.
Site Conditions
Area to receive and store access floor materials shall be enclosed and maintained at ambient
temperatures between 35 to 95 F and relative humidity levels between 20 to 80%. At least 24 hrs.
before installation begins, all floor panels shall be stored at ambient temperatures between 50 to
90 F and relative humidity levels between 20% to 80% and shall remain within these environmental
limits throughout occupancy.
Performance Criteria
Access floor panels laminated with porcelain tile require a minimum panel rating of a ConCore 1500. Due to the nature of the
porcelain, the performance rating of the panels will be as follows:
Design load – 1000 lbs. when tested on bolted stringer understructure using CISCA test methods (with loads applied
through a 1” indentor at the weakest point)
Ultimate load – 1600 lbs. when tested on bolted stringer understructure using CISCA test methods (with loads applied
through a 1” indentor at the weakest point). Ultimate load is the point at which the tile cracks, not failure of the panel
Dynamic loads:
o 10 pass using a 3” diameter x 1-13/16” wide rubber wheel – 800 lbs.
o 10,000 pass using a 6” diameter x 2” wide urethane wheel – 600 lbs.
Impact loads – Impact loads should always be avoided as they will damage or crack the porcelain
* The above criteria must be complied with or damage to the tile will occur. Please contact an
authorized Tate dealer or call the Tate Technical Hotline at 1-800-231-7788 for procedures to follow
when wheel sizes and loads differ from those identified in Tate product specifications.
Construction Phase
During the construction and move in phase, a minimum of 3/4” plywood must be used to protect the
floor, without exception. All materials and equipment used by other trades must be reviewed and
approved by the Tate dealer/installer prior to the material or equipment being permitted on the
Equipment Moving Precautions
The access floor must be protected from overloads and circumstances that exceed its specifications.
Movement of heavy loads and equipment may require protection of the floor system through the
use of plywood or other suitable load-distributing materials. Contact Tate’s Technical Services
hotline for any instances that exceed recommended loading practices.
Expansion joints and thresholds must be protected with a minimum of 3/4” plywood if any loads are
to be rolled over them. Dynamic loads should always be avoided on panels with cutouts or cut panels at doorways or
perimeters. If this cannot be avoided, please contact Tate’s Technical Hotline to evaluate a safe operating recommendation.
Approved Lifts
No panels may be removed from the access floor system and perimeter panels must be installed before lifts are permitted on
the floor. Panels with cutouts must be removed and replaced with full panels. Utility panels such as PVD boxes and Air Diffusers
must be removed and replaced with solid panels. The user is responsible for extra panels if needed. The user is responsible to
replace any damaged panels or accessories.
Multiple lifts operating on the access floor are not to be any closer to one another than 3 feet or 1 meter.
The weight and load capacity have been calculated to be within the 10,000 pass rolling load capacity of the ConCore 1500
panel with factory laminated porcelain tile on bolted stringer understructure. Popular man-lifts and scissor lifts that may be

Removal and Reinstallation
An access floor can become misaligned due to mishandling or abuse when working under it. Follow
these procedures for removal and replacement of panels and stringers to maintain the system in its
original condition.
The following tools are required to remove panels and stringers from your floor.
Battery powered screw gun
#3 Philips replacement tips for screw gun
Panel lifter (available through your Tate dealer)
Do not use screwdrivers, pliers or other tools to pry or lift panels.
Be cautious not to inadvertently rotate pedestal heads and change height settings
when panels are removed. Although pedestal heads have anti-rotation mechanisms, it
is still possible to bump heads out of alignment.
Do not attempt to carry a panel by the lifter – the suction could break and allow the
panel to fall from your hand.
After removing cut panels installed at walls and around columns, reinstall them exactly
where they came from. Interchanging panels that were precisely cut for perimeter
locations can cause interior panels to be tight or loose in the floor and also cause the
floor to be out-of-square.
It is good practice to remove panels only where immediate access is required and reinstall them as
your work progresses. When a number of panels must be removed, do not take out more than six
adjacent panels at once OR remove only every other panel in a row.
The first panel taken out must be pulled with lifters. Adjacent panels can be removed with the lifters
or by reaching underneath them and pushing upward. Kneeling on the floor while removing and
replacing panels may avoid back strain.
Due to the weight of the panels, it is recommended that when it is necessary to remove or reinstall
panels, 2 double cup lifters are used. Lifters should be used on opposite sides of the panel. One lifter
should be used to carefully lift one side of the panel out of the grid at an angle. The panel can then
be lifted out using both lifters, being careful not to drag or bump the PVC edge band on the panel
being lifted, or adjacent panels. Never drop or slam a panel on adjacent panels or damage to the
porcelain will occur
All but the last panel reinstalled can be seated on the understructure without a lifter. To
reinstall a panel, sit one edge on the understructure and lower the other side as if closing a
door, being careful not to bump or drag the adjacent panel and PVC edge band. To reinstall a
panel using a lifter, attach the lifter near an edge and lower that side into place. Never drop
a panel into place.
Panel Cutting Procedures
Factory Cuts
Whenever possible, cutouts should be ordered from the factory to ensure proper fit of electrical
boxes, grilles, grommets or other access floor accessories. It will also save time and expense at
the job site. Interior cuts not done in the factory will need to be waterjet cut. When field cuts
can’t be avoided such as perimeter cuts, the following guidelines should be followed.
Safety Requirements for Panel Cutting
Work in a well-lighted area
Be sure tools are properly grounded and dry.
Use common sense to avoid personal injury. Always use safety equipment
o Ear protection
o Safety glasses and full face shield (clear plastic)
o Long sleeve shirt or sleeve protectors
o Lightweight work gloves for protection from sharp metal edges and hot
saw dust)
o Steel toe safety shoes or boots
Straight and Curved Cuts
Cutting straight cuts is a 2 part process. Layout your cut line and start by cutting through the
porcelain only using a wet cut bridge saw with an @ 8” diamond blade (such as Pearl Abrasives)
rotating at @ 3,260 RPM. Then use a bi-metal bandsaw blade (such as Lenox Classic M42) with
14 teeth per inch to cut through the ConCore panel.
For cutting curved cuts that can’t be avoided in the field, use a bandsaw blade with a tungsten
carbide blade, with a continuous grit or gulleted blade (such as Lenox Master Grit). Cut very
slowly though both the porcelain and the panel at the same time. For tight corners and shapes,
use an angle grinder (such as Hilti 4.5” grinder) with a 4” to 4-1/2” porcelain cutting blade (such
as Eco Diamond Contractor Series) rotating at @ 10,000 RPM. Rates of feed should be judged by
the person doing the cutting, but it will be relatively slow. 5 minutes to get through the porcelain
alone is not uncommon.
Supporting a Cut Panel
To prevent the porcelain on panels with cutouts from cracking, an effective solution is to use
additional pedestal supports. Guidelines for the number and location of additional supports
are outlined below:
Initial Pre-Occupancy Cleaning &
Preparation Guidelines
Initial care can be carried out with a damp microfiber mop or a scrubber drier. For either option, the
first step is to sweep and vacuum any loose dust, dirt or debris from the floor. It is important not use
excessive water or flood the floor.
Microfiber floor mop
Use a slightly damp mop with a high proportion of microfibers (at least 50%). For lightly textured
floor tiles, use a deep-pile microfiber mop. If desired, add a small amount of mild detergent or
vinegar to the water. Make sure that the cleaning product is suitable for unglazed floor tiles.
Scrubber drier machines
Wash the floor with water and detergents suitable for ceramic surfaces. Add a small amount of mild
detergent or vinegar to the water in the machine. The cleaning product should be low-lather so that
it can be used in scrubber drier machines and suitable for use on unglazed floor tiles. For smooth
tiles, use at most a red scrubbing disc. Minimal water should be used
The surface of porcelain is basically non-absorbent and does not require the use of wax and/or
similar products, which, conversely, should never be used. It should be pointed out that porcelain is
resistant to any chemicals with the exception of hydrofluoric acid, a very aggressive agent for ceramic
products that should never be used. Once cleaning is completed, isolate the cleaned floor until it has
completely dried.
Regular Maintenance
Regular vacuuming or wiping prevents the accumulation of dust and dirt. The floor will need to
be cleaned regularly to remove more tenacious dirt. Prior to cleaning, first remove loose dirt by
vacuuming or sweeping. Use a slightly damp mop with a high proportion of microfibers (at least
50%). For lightly textured floor tiles, use a deep-pile microfiber mop. If desired, add a small
amount of mild detergent or vinegar to the water. Make sure that the cleaning product is
suitable for unglazed floor tiles.
