A Complete Line of Pool Deck Products

DECK-O-SEAL – Polysulfide-Based Joint Sealant

DECK-O-SEAL - Polysulfide-Based Joint SealantSeal all cracks and joints with DECK-O-SEAL two-part, elastomeric, polysulfide-based joint sealant. DECK-O-SEAL is used for caulking and sealing joints subject to concrete movement to provide a firm, flexible, weather-tight seal. It is ideal for sealing joints around swimming pools, and is applicable for both interior and exterior use. DECK-O-SEAL is highly resilient and has excellent recovery characteristics after extended periods of compression or elongation.

  • Highly resilient with excellent recovery characteristics
  • Provides permanent and uniform watertight seal.
  • Prevents uncontrolled cracking by allowing expansion and contraction during temperature changes.
  • Stays flexible … won’t become brittle or crack due to ultraviolet exposure.
  • Resists abrasion, weathering and moisture … elevated temperatures will not cause discoloration.
  • Not affected by today’s pool chemicals.
  • Retains joint soundness in service once it’s cured and can be stretched or compressed up to 25%.

DECK-O-SEAL
Two-Part, Elastomeric, Polysulfide-Based Joint Sealant

DESCRIPTION
DECK-O-SEAL two-part, polysulfide-based joint sealant is a premium-grade, pourable, self-leveling sealant.  It is a non-staining sealant that cures at an ambient temperature to a firm, flexible, tear-resistant rubber. DECK-O-SEAL is highly resilient and has excellent recovery characteristics after extended periods of compression or elongation.  DECK-O-SEAL has outstanding resistance to most chemicals, to all weather conditions, aging, and shrinkage.

USES
DECK-O-SEAL is used for caulking and sealing joints subject to movement to provide a firm, flexible, weather-tight seal.  It is ideal for sealing joints on swimming pool decks.  It is applicable for both interior and exterior use.

FEATURES/BENEFITS

  • Highly resilient with excellent recovery characteristics.
  • Provides a uniform, watertight seal.
  • Prevents uncontrolled cracking by allowing expansion and contraction during temperature changes.
  • Stays flexible … won’t become brittle or crack due to ultraviolet exposure.
  • Resists abrasion, weathering, and moisture … elevated temperatures will not cause discoloration.
  • Not affected by today’s pool chemicals.
  • Retains joint soundness in service once it’s cured and can be stretched or compressed up to 25%.

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 and 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″ (50.8 mm) wide to the surfaces adjoining both sides of the joint before REZI-WELD LV from W. R. MEADOWS and/or DECK-O-SEAL are applied.

Priming … DECK-O-SEAL adheres well to unprimed concrete; however, REZI-WELD LV is recommended for optimum adhesion.  REZI-WELD LV is required for all joints subjected to hydrostatic pressure, submersed underwater, and/or joints over 1″ (25.4 mm) in width.

Joint Sizes … Proper joint design practices and application techniques must be followed for successful performance.   DECK-O-FOAM® or KOOL-RODTM 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-asphalt 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 depthbe less than 1/4″ (6.4 mm) or exceed 1/2″ (12.7 mm).  DECK-O-SEAL should NOT be used in joints less than 1/4″ (6.4 mm) wide.

Mixing … DECK-O-SEAL 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. Mix small can (setting agent) first, then pour into larger can.  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 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 (96 oz. kits only), 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 will set firm and rubbery within 24 hours at 77° F (25° C).  At lower temperatures, curing time may take longer.

Cleanup … Application equipment should be cleaned promptly with xylene or toluene.

PRECAUTIONS
DECK-O-SEAL is not compatible with asphalt and cannot be used in asphalt concrete pavement or with asphalt-impregnated expansion joint fillers.   NOTE: It is not recommended to apply paint over  DECK-O-SEAL products.  DECK-O-SEAL cannot be used underwater.  Only DECK-O-SEAL 125 or DECK-O-SEAL GUN GRADE should be used in joints under the waterline and it is strongly recommended that joints under the waterline be installed by a professional contractor trained in joint sealing application techniques.  For all underwater applications, SELF-EXPANDING CORK EXPANSION JOINT from W. R. MEADOWS should be used as the backer rod in the joint.
