CAUTION! As with all chemical products, individuals may have different reactions to exposure to specific products. This is dependent upon many factors, including the individual’s personal characteristics, the size of the installation, the ventilation available, the intensity of the exposure or the length of the exposure. Individuals may experience discomfort during the installation process of one product, but not another. In some cases this is experienced as a skin irritation and in others it is experienced as an inhalant irritation. Typically, it disappears once the exposure is eliminated. In some cases people can become “sensitized” to a product and experience the discomfort every time there is exposure without Personal Protective Equipment (“PPE”). To protect yourself from various exposures or discomfort during the mixing and application of our products, we recommend covering exposed skin including, using gloves, long sleeves, safety glasses and a respirator such as the 3M 8577 P95 Universal Disposable Carbon Respirator or a cartridge respirator. Use only as directed. KEEP OUT OF REACH OF CHILDREN. Do not reseal moisture-contaminated hardener.

23 CLEANING GUIDELINES WHY CLEAN YOUR FLOOR? Appearance: Your floor will look its best when it is clean. By establishing a scheduled cleaning program, the floor will continue to look and perform as it did when it was first installed. Safety: No matter how aggressive the texture of your floor, if it is not cleaned properly, it can present a slip hazard. Emulsifying, rinsing and drying your floor properly will reduce the risk of a slip and fall incident. Note: Wet environments need to be kept dry as possible to prevent slip and falls. Proper signage, non-slip shoes, floor fans, and walk-off mats will help prevent slip and falls in any facility Service Life: The lifetime of your floor will depend upon how well you clean it. In aggressive use areas (i.e. kitchens and machine shops) contaminants such as oil, dirt, and grease work with water and bacteria to break down the floor.

FLOOR CLEANING PROCESS & TOOLS The best way to clean a Dur-A-Flex floor is to use the recommended cleaning product and follow a six-step process. (Equipment needs vary between small and medium/large floor areas.)

Process Small Area Medium/Large Area Sweep floor thoroughly Broom, Dust Mop Floor Sweeper, Broom Automatic Floor Scrubber, Apply cleaning product on floor surface Deck Brush, Foamer/Sprayer Foamer/Sprayer Dwell - allow cleaning product time to emulsify foreign 10-15 Minutes 10-15 Minutes material Deck Brush, Rotary Floor Automatic Floor Scrubber, Agitate to aid in the release of foreign materials Machine Rotary Floor Machine Squeegee (Soft Neoprene) Wet Remove cleaning product from the floor Automatic Floor Scrubber Vacuum Wet Vacuum, Squeegee (Soft Rinse the floor with clean water and remove Automatic Floor Scrubber Neoprene)

NOTES • Wax strippers should never be used on a Dur-A-Flex Floor • When removing solution with a squeegee, use a soft, neoprene • Never use Enzyme based cleaners on a Dur-A-Flex Floor squeegee. Do Not use a water spray to remove cleaning solution • DO NOT use “No-Rinse” cleaners as the chemical from the floor because it will over-dilute the solution and cause concentration can increase in the residual film left behind grease and oil to fall back onto the floor. • Combinations of chemicals can result in staining or • Spills should be cleaned up immediately to prevent staining and degradation if not properly rinsed and removed as a safety precaution. • Never use a mop to clean a floor that is greasy or oily. • Surfaces should be adequately protected when moving heavy • Make sure the pads or brushes on the automatic scrubber are equipment across the floor. in good shape. Pads should be non-abrasive white, tan or red • Through proper training and education, unnecessary wear of the 3M cleaning pads or equivalent. Brushes should be nylon non- floor (such as forklift spin and skid-marks) can be avoided. abrasive Malish 8129 series or equivalent soft to medium flex nylon bristle brush. • When using a deck brush, choose a medium/stiff bristle. • When using a floor cleaning machine, a pad is recommended for use on smooth floor systems, while a soft to medium flex nylon bristle brush is recommended for broadcast floor systems or smooth floor systems with added texture. 24 RECOMMENDED CLEANING PRODUCTS Determining the correct cleaning product for your Dur-A-Flex floor is based upon the amount and type of soiling the floor receives. We have divided these into four types, and recommended a cleaning product for each instance:

Application Typical Areas Product Product Description Traffic Areas Hallways, Healthcare Facilities, Labs, EZ-CLEAN (Light soils) Dining Areas, Schools EZ-CLEAN is a heavy-duty alkaline floor cleaner designed to remove protein or Moderate/Heavy Grocery Stores, Restaurant Kitchens, EZ-CLEAN crude based soils (Protein soils) Animal Care, Food/Beverage Processing SIMONIZ 969 is a heavy duty, highly Moderate/Heavy Manufacturing/Industrial, Machine/ SIMONIZ 969 alkaline floor cleaner designed to remove (Crude soils) Automotive Service Centers, Warehouses machine and crude oil from concrete TIRE MARK REMOVER is a heavy duty TIRE MARK cleaner designed to remove rubber skid Rubber Tire Marks Forklift Tire Spin REMOVER marks from polymer type floors as well as hard steel troweled floors

The above Dur-A-Flex cleaning products may be ordered directly from Dur-A-Flex Customer Service at 1-800-253-3539 or via email at [email protected]

WHEN TO CLEAN YOUR FLOOR Dur-A-Flex floors are designed for and used in heavy traffic areas that typically accumulate foreign matter. Because of this, the recommended maintenance schedule for most areas is once or twice daily cleaning and regular “touch-ups” for spills. Less frequent cleaning of these areas results in a buildup of foreign matter, which diminishes the appearance, safety and service life of the floor.

Our CRYL-A-FLEX MMA products develop to full cure in one hour, and full cure for most epoxy and urethane systems is 7 days at 68°F. The lower the room temperature -the longer the cure time. Avoid chemical spills and full traffic during cure period. Premature exposure may cause permanent staining or discoloration. Do Not use abrasive cleaning methods during the first week after installation.

WALL CLEANING PROCESS 1. Application – Apply EZ-CLEAN, follow cleaner guidelines for dilution rate, use with hot water while using a deck brush, foamer/sprayer or power washer. 2. Scrub walls with deck brush 3. Rinse walls with clean water

The two basic joint types are Moving (dynamic) and Non-Moving (static).

Moving Joints

Construction, Expansion and Isolation joints are considered moving joints which allow horizontal and vertical movement between the slab and adjoining structures, such as walls and columns, helping to minimize cracking where the two meet.

Prior to filling moving joints Dur-A-Flex, Inc. recommends “honoring” these joints by making a saw cut through the finished floor system at a depth of ¾” deep and ¼” wide with a diamond blade saw attached to a vacuum. A bond breaker such as backer rod (closed cell) must be added to the bottom of the joint. Be sure to mark the location of the joints prior to the installation of the finished floor.

Potential cracking and or stress/stretch lines (white lines) may occur on all resinous floor systems over or on either side of moving joints if the joints are not saw cut and properly filled. Also if there is a variance of temperature of 20 degrees or more from the time the joint is filled and coated to its operational temperature, hairline cracking could occur even on non-moving joints.

Non-Moving Joints

Control and or Contraction joints are considered non-moving joints which accommodate shrinkage and relieve internal stresses during the curing process of the concrete.

“Warranties: Seller warrants that its goods, as described on the face hereof, are free from any defects in material or workmanship. Seller makes no other warranty, express or implied, and all implied warranties of merchantability and fitness for a particular purpose are hereby disclaimed. Seller shall not be liable for prospective profits or special indirect or consequential damages. Seller’s sole liability and buyer’s exclusive remedy for breach of any warranty as expressly limited, at seller’s option, to replacement at the original F.O.B. point or refund of purchase price. Seller shall not be responsible for any claim resulting from failure to utilize product in the manner in which it was intended26 and in accordance with instruction provided for use of product. Any claim for breach of warranty shall be deemed waived unless buyer shall give seller written notice of such claim within sixty (60) days after delivery and shall allow seller reasonable opportunity to investigate claim and inspect product.”

Prior to filling non-moving joints be sure to prepare them by removing all laitance, debris and sealers to a depth of ¾”deep and ¼” wide with a diamond blade saw attached to a vacuum. A bond breaker such as silica sand (30-40 mesh) at ¼” deep may be added to the bottom. This will stop the joint material from seeping if the concrete is cracked through.

Repair of damaged/spalled joints

Saw cut each side of spalled area and chip out the center with a chipping hammer or consider the use of a series of blades to reach the proper width. If using multiple blades, the center blade should reach the depth of the original joint and the outer blades should achieve a cut creating a “T” shape after cutting.

Installation Timing

The American Concrete Institute (ACI) recommends that filling of industrial floor joints be deferred 60-90 days after floor slab pour or as long as possible. This is to allow control and construction joints time to open closer to their ultimate width through the concrete shrinkage process. (In freezer/cooler areas, floor should be stabilized at ultimate operating temperature for 7 days prior to installation).

Prior to treatment of joints be sure to contact the facilities owner or manager to determine how long the concrete has cured as well as the location of moving and non-moving joints.
