DECK-O-SEAL® 150
Two-Part, Pourable Joint Sealant

DESCRIPTION
DECK-O-SEAL 150 Two-Part, Pourable Joint Sealant is a self-leveling, polysulfide-based sealing compound. DECK-O-SEAL 150 is a non-staining sealant which cures to a firm, flexible, tear-resistant rubber. It is highly resilient and has excellent recovery characteristics even after extended periods of compression or elongation. DECK-O-SEAL 150 has outstanding resistance to most chemicals, to all weather conditions, aging and shrinkage. For on-the-job use, DECK-O-SEAL 150 is supplied in 96 oz. (2.84 liter), pre-measured kits consisting of the base compound and a separate container of setting agent. There is enough room in the base container for introduction and mixing of the setting agent.

USES
DECK-O-SEAL 150 is designed for general purpose sealing of joints and seams that are saw cut in forklift traffic areas.

APPLICATION
Follow these instructions carefully for maximum effectiveness. BE SURE TO WEAR PROTECTIVE SAFETY GLASSES AND CHEMICAL-RESISTANT GLOVES.

Surface Preparation...Remove foreign substances, incompressibles and free water from joint opening. For proper adhesion, joints must be clean and dry. Dust, dirt and laitance should be removed prior to application. Concrete should be completely cured, free from all foreign materials and contamination from curing agents. (Industry accepted standard for curing concrete is 28 days). To maintain cleanliness around the joint to be sealed, apply masking tape 2" wide to the surfaces adjoining both sides of the joint before P/G PRIMER and/or DECK-O-SEAL 150 is applied.

Priming…DECK-O-SEAL 150 adheres well to unprimed concrete, however P/G PRIMER from W. R. MEADOWS is recommended for optimum adhesion. P/G PRIMER is required for all joints subjected to hydrostatic pressure, submersed under water and/or joints over 1" in width.

Joint Sizes…Proper joint design practices and application techniques must be followed for successful performance. DECK-O-FOAM® or KOOL-ROD™ from W. R. MEADOWS may be used as a joint backing material to control sealant depth and provide proper joint configuration. For larger joints, use a non-asphaltic joint filler, such as Cork Expansion Joint from W. R. MEADOWS in the joint before sealing.

A 2:1 width-to-depth ratio should be maintained. However, in no case should joint sealant depth be less than 1/4" or exceed 1/2". DECK-O-SEAL 150 should NOT be used in joints less than 1/4" (6.35mm) wide.

Mixing…..DECK-O-SEAL 150 is supplied in pre-measured kits with a ratio of setting agent to base, which must be maintained. Store and mix in a cool, shaded area. Do not mix until ready to use. (Product cannot be re-sealed for future use).

De-rim both cans with a can opener. Pour the setting agent into the base and mix slowly. To aid in proper mixing, scrape material from the sides and bottom of the container until a uniform color is obtained. Continue mixing for a recommended 10 minutes, minimum. A slow-speed drill can be used. Care must be taken to ensure that all the setting agent is thoroughly blended with the base component. Avoid trapping air in the sealant.

Application Method…At 77°F (25°C) and 30% relative humidity, the application life is approximately one hour. Apply thoroughly blended material with supplied squeeze bottle, caulking gun or any other suitable applicator. Be sure to remove masking tape from both sides of the joint before the sealant starts to set. DECK-O-SEAL 150 will set firm and rubbery within 24 hours at 77° F. At lower temperatures, curing time may take longer.

Clean-Up...… Application equipment should be cleaned promptly with Xylene or Toluene.

PRECAUTIONS
DECK-O-SEAL 150 is not compatible with asphalt and cannot be used in asphalt concrete pavement or with asphalt-impregnated expansion joint fillers.

HEALTH AND SAFETY
Avoid skin contact. If contact should occur, wash immediately with soap and water. Refer to Material Safety Data Sheet (MSDS) for complete health and safety information.
