Pre-installation visit

Moisture and alkalinity test

New concrete needs at least 90 days to dry under ideal conditions. Lightweightconcrete and concrete poured above grade in metal pans take a considerablylonger time to dry. Installation cannot begin until it is fully dried and in compliancewith moisture and alkalinity requirements.

The temperature of your job site must stay within 60F (15.5C) and 85F(29.5C) 48 - 72 hours prior to, during, and 48 - 72 hours after installationso be sure the heating and air conditioning system is operating.

All carpet tiles must be removed from the cartons and allowed to adjust tothe job site temperature for 48 hours prior to installation.

Before installing Interface GlasBac/GlasBacRE carpet tiles over a new orexisting concrete subfloor, you must test the moisture and alkalinity levels ofthe concrete.

Moisture conditions of the concrete should be determined by use of the in SituProbe rH test method (ASTM F 2170). Moisture conditions must not exceed

75% rH except when installing with TacTiles connectors over new or bareconcrete, which allows for installation up to 80% rH.

Although not as accurate, moisture emission rates can be tested using theCalcium Chloride test method (ASTM F 1869). When using this method, theemission rates must not exceed 3.0lbs/1000sf/24hrs. For warranty purposes,any time an issue related to moisture occurs, the in Situ Probe rH test methodsupersedes the Calcium Chloride method for determining moisture conditionsof the concrete. NOTE: Results obtained by these methods reflect only theconditions of the concrete at the time of testing. If the concrete moistureexceeds these limitations, do not proceed with the installation. Call the InterfaceHelp Desk U.S. (877) 733-7403 / Canada (888) 224-2972. Stated moisture andpH limitation must be maintained for the life of the installation to avoid installa-tion and product failures and to preserve warranty coverage.

60F (15.5C) - 85F (29.5C)

90 Days

NOTE: The required pre-installation moisture and alkalinity tests should beperformed to ASTM standards.

Per CRI guidelines it is recommended that these tests be performed by aqualified independent testing consultant.

Interface will not be responsible for failures, problems, or damage arising fromhigh moisture, high alkalinity, or other subfloor conditions.

NOTE: New or bare concrete is defined as concrete free of adhesive residue,paint, sealers, primers and other applied materials.

Moisture and alkalinity test (continued)

Product inspection

All concrete floors, old and new, should be tested for alkalinity by using analkalinity test kit. The pH test papers should be capable of measuring a range of0 - 14. The area to be tested must be weather-tight and conditioned, via thebuildings HVAC system, to a temperature range of 65 - 85 Fahrenheit and arelative humidity range of 40% - 60%. This temperature and humidity rangemust be maintained for at least 48 hours immediately prior to commencing thetest, and at all times during the test. All adhesives, coatings, finishes, dirt, curingcompounds, sealant and other substances that may affect the rate of moisturedissipation must be removed from the area to be tested. Non-chemical methods

such as abrasive cleaning or bead blasting may be used on existing slabs toachieve an appropriate state for testing.

Once this criteria has been met:1. Abrade the surface by scratching into the clean slab a minimum of 1/32 but

no more than 1/8.2. Apply a small amount (approx. 1 in diameter) of de-ionized or distilled water.3. Allow the de-ionized/distilled water to stand for 60 seconds.4. Dip the 0-14 pH test strip into the puddle and remove immediately.5. Compare to the test kits associated pH chart to determine the pH.6. At least one pH test must be performed for every 1,000 square feet of space.

The slab should have an alkalinity level between 7.0 - 9.0 to be suitable forcarpet installation. Should the pH level be outside of this range, STOP and DONOT proceed with installation.Call the Interface Help Desk. U.S. (877) 7337403 / Canada (888) 224-2972

NOTE: Test results reflect the condition of the slab at the time of testing.Interface recommends the use of MoistureGard 2.0 prior to installationof the carpet when moisture and pH conditions are outside specified limits.MoistureGard 2.0 provides protection against moisture vapor emission ratesof up to 90%rH and pH up to 12.0. When MoistureGard 2.0 is used, the carpetmust be installed with Interface TacTiles connectors. Moisturegard 2.0and TacTiles cannot be used on stairs, ramps or inclines. Guidelines for theapplication of TacTiles can be found in this document. For more information onMoistureGard 2.0 contact your Interface Account Executive or call theInterface Help Desk. U.S. (877) 733-7403 / Canada (888) 224-2972

INSPECT INTERFACE GLASBAC/GLASBACRE CARPET TILES TOBE SURE THEY MEET THE ORDER SPECIFICATIONS. IF THEWRONG PRODUCT OR COLOR IS INSTALLED, Interface WILL NOTBE RESPONSIBLE FOR CORRECTING THE PROBLEM.

The labels on each carton indicate product style, pattern, color, run number anddye lot. Be sure the style, pattern and color match the specifications for eacharea of your installation. On larger installations, you may find that some cartonshave different run numbers and/or dye lots. Dye lots may be mixed for Interfacei2styles. To avoid subtle variations in the finished installation of non-i2 styles,do not mix run numbers or dye lots in the same area.

Check to confirm that you have the right quantity and correct installation method.

Be sure you also have enough tiles to establish an attic stock for futurereplacements.

Open all cartons to inspect for damaged or defective tiles. If you find any,call the Interface Help Desk. U.S. (877) 733-7403 / Canada (888) 224-2972

ESTABLISHING THE STARTING POINT

1. Measure to determine the center point and mark. Snap a chalk line.

2. Measure 8 feet (243.5 cm) out from your center point along the chalk line. Make a mark.

3. Measure 6 feet (182.9 cm) from your center point at a right angle to yourchalk line and make a mark.

4. Measure the distance between your marks. It should be exactly 10 feet (304.8 cm). If it is, your quadrants will be square. Snap a chalk line here.

NOTE: If the room is too small for the above measurements, reduce them byhalf. Measure 4 feet (121.9 cm) vertically and 3 feet (91.4 cm) horizontally. Inthis case, the measurement between your two marks should be exactly 5 feet(152.4 cm).

Adhesive in special situations

Apply adhesive with a 1/2 nap paint roller. Expect a spread rate of 40-45square yards per gallon using a 1/2 nap paint roller.

For raised floor systems a full spread of adhesive is required.

FLATWIRENever apply adhesive directly over flatwire. The flatwire may be damaged if thetiles need to be removed.

UNEVEN AREASAny surface that cannot be leveled may require adhesive or double-sided tapeto hold a tile in place.

Using a 1/2 nap paint roller, apply adhesive along each base line to anchorthe starting rows.

Adhesive must also be applied at all room perimeters (each wall).

The application rate for a grid adhesive method is 180 square yards per gallon.

Grid size should not exceed 10. Grid size should be adjusted based onexpected traffic flow. Grids can range from 1-10.

NOTE: A full spread of adhesive must be applied under every cut tileand any adjoining tile to the cut tile. Full spread is also required in anyarea that will be exposed to high foot traffic and/or heavy rolling traffic

LAYING TILES

Tile Installation

Tip into place

Lay tiles in step or pyramid pattern

Follow the center lines closely. In smaller rooms, your anchor rows may consistof fewer than 11 tiles. Lay an anchor row of 10 additional tiles (11 including theone youve already placed) aligned with the center line.

Measure your anchor rows. Each should equal 550 cm (11 tiles x 50 cm each,or 216 17/32) with no more than a 3mm (1/8) gain. If the gain is more than3 mm, the tiles arent tight enough and should be laid again. After relaying,measure again. If tiles are less than 550 cm they are too tight and should belayed again.

Dont position tiles by sliding them across the adhesive. This will cause the

corner to bend under. Instead, brush the pile back with one hand, then tipa corner of the tile into place. Position the rest of the tile once the corneris properly aligned. Do not catch the pile in the joints.

1. Lay two tiles vertically, and check that they are square to the anchor rows.

2. Lay two tiles horizontally, and check that they are square to the anchor rows.

3. Lay one tile to complete the step.

4. Follow the ABCD pattern laid out here until you reach the end of your anchorrows. Repeat laying anchor rows and ABCD patterns in all quadrants untilcomplete.

CUTTING TILES

PREPARING FOR OCCUPATION

Guidelines for cutting tiles

Final inspection and vacuum

Tiles adjacent to fixtures, architectural elements and walls need to be cut.Follow these guidelines:

If practical, remove the base molding before installing perimeter tiles. Replace molding when finished. Replace blades often. Sharp blades make cutting quicker, easier and more precise. Never use other tiles as a cutting surface. Place tiles on layers of cardboard before cutting. Always secure cut tiles with adhesive.

Inspect the entire installation, paying close attention to joints and any tilesthat have been cut.

Vacuum the floor with a pile lifter. If you dont have a pile lifter, use an uprightvacuum cleaner.

Raised floors

Floor outlets are usually wired aftercarpet tiles have been installed.Consequently, you should install tilesdirectly over floor outlets and mark

the location with tape. This way, itwill be easy to see which tiles needto be lifted for cutouts later.

Tile layout should allow trenchheaders to be centered under arow of tile. Secure the tiles on eitherside of trench headers with adhesive.This will prevent the installationfrom shifting while servicing trenchheaders.

Tile layout should allow flatwire tobe centered under a row of tile.

Raised floor panels are susceptibleto subtle flexing. To ensure uniformappearance, avoid matching raisedfloor seams with tile joints.

Follow CRI installation standards

In addition to the specific floor preparation and installation instructions detailed here, the Carpet and Rug Institutes Carpet Installation Standardmust be followed. Please note that many of the Interface installation requirements may exceed or differ from those in the CRI Standard. In theevent of conflict between the Interface Installation Instructions and the CRI Standard, you should follow the Interface Installation Instructions.
