SELF-LEVELING URETHANE JOINT SEALANT
SEALANT DEPTH: For optimum sealant performance, the joint sealant depth should be controlled to provide 1/4" (6.3mm) minimum depths for joint widths up to 1/2" (12.7mm); for up to 1" (25.4mm) widths, the sealant depth should be 1/2 the joint width; for joints over 1" (25.4mm) wide, the sealant depth should be maintained at 1/2" (12.7mm).
To control sealant depth SEALTIGHT KOOL-ROD backer rod, or a non-asphaltic joint filler, such as SEALTIGHT CERAMAR® is required. Joint filler will help support the sealant to bear pedestrian traffic. In addition to giving support to the sealant, the joint filler should be held in compression in the joint to prevent the pourable sealant from passing through or leaking from the joint.
JOINT PREPARATION: Joint surfaces must be clean, dry and free of all contaminants such as curing compounds, form release agents, coatings, oil, grease or bitumens. All will interfere with the adhesion of the sealant. For new concrete, remove laitance and loose material by wire brushing or abrading. Joint surfaces exposed to form release agents or curing compounds should be sandblasted. Dust and dirt should be blown out of the joint by compressed air.
For old concrete, all old joint sealing compounds must be removed. Joint surfaces containing absorbed oils or bitumens must be cut back to clean, sound surfaces. Metal surfaces must be clean of all rust or oxide coatings and wiped clean with Xylene or Toluene.
PRIMING: All surfaces, to which the POURTHANE Sealant is to adhere, must be primed with SEALTIGHT P/G Two-Part Primer. Thoroughly mix the two components of the priming system and apply to the joint surfaces by brushing a thin continuous coating on the joint faces. Primer should be applied 30-60 minutes before sealant is installed and have a slight tacky surface at time of sealant installation.
MIXING: The 2 components of POURTHANE must be thoroughly blended following the mixing directions on the label. After combining the two components, use a flat bladed paddle and slow speed drill (150 rpm) to mix the two components for 8-10 minutes, moving the mixing blade throughout the sealant. Scrape sides of pail and bottom to insure the mixing of all material and remix with drill for approximately 3 minutes.
After mixing the 2 components, POURTHANE will be pourable for two hours at 75ºF (24ºC); application time will be decreased at higher temperatures and extended at lower temperatures. Do not mix more material than can be used in 2 hours.
APPLICATION TECHNIQUE: After cleaning of the joint, priming and installation of the back-up filler, POURTHANE may be poured into the joint using any suitable pouring container in relation to the size of the joint. For appearance and ease of application, exposed surfaces on each side of the joint may be taped; remove tape before POURTHANE begins to thicken or cure. Avoid overfilling the joint.
CLEANUP: Equipment may be cleaned with Xylene or Toluene before the sealant cures.
