Sikaflex-444 Rapid Sealant 3 Gallon Pail - Limestone

Sikaflex-444 Rapid is a one component, polyurethane-based sealant that when mixed with the booster (sold separately), cures to a durable rubber finish that can be opened to vehicular traffic in approximately 4 hours after application. Sikaflex-444 Rapid will cure without the booster, but the cure speed will be significantly slower. Sikaflex-444 Rapid is principally a moisture cured sealant with a semi-self-leveling consistency that can be applied to slopes as great as 20%.

Features & Benefits

• When mixed with Sikaflex-444 Rapid Booster, cures in approximately 4 hours and is capable of receiving vehicular traffic.
• Semi-self-leveling consistency; capable of handling up to a maximum 20% slope.
• Will fully cure more slowly if Sikaflex-444 Rapid Booster is not added.
• Capable of +/- 50% movement in certain well-designed joints based on actual field conditions.
• High elasticity with a tough, durable, flexible consistency.
• Exceptional cut and tear resistance.
• Exceptional adhesion to most substrates without priming.
• Easy to mix.
• Jet fuel resistant.

Applications

• Ideal for cracks and expansion joints in parking decks, sidewalks and other concrete traffic surfaces.
• Also intended for use in properly designed, working, nontraffic joints with a minimum depth of 1/4 inch (6 mm).
• For horizontal applications only with slopes equal to or less than 20%.
• Placeable at temperatures as low as 40 °F (4 °C).
• Adheres to most substrates commonly found in construction.
