Euclid Eucolastic 1SL is a single-component, self-leveling polyurethane hybrid sealant in 30 oz cartridges. It is placed in horizontal joints that see rubber tires and foot traffic and holds a slope up to 6 percent.
Euclid Eucolastic 1SL is a single-component, self-leveling, moisture-cure polyurethane hybrid joint sealant. It is used in horizontal control and expansion joints that take rubber-tire and pedestrian traffic, including sidewalks, plazas, and traffic-loop seals. The sealant holds a slope up to 6 percent and remains adhesively and cohesively bonded through temperature cyclic movement.

Eucolastic 1SL Technical Data Sheet
What slope does Euclid Eucolastic 1SL hold?
Euclid Eucolastic 1SL holds a slope up to 6 percent (ASTM C639 Grade P). Expect reasonable variation under field conditions.
What traffic is Euclid Eucolastic 1SL used for?
Euclid Eucolastic 1SL is formulated for superior wear resistance to rubber tires and pedestrians in high traffic areas. It is used on sidewalks, truck terminals, plazas, pool decks, and as a traffic-loop sealant.
What elongation does Euclid Eucolastic 1SL show?
Typical laboratory elongation is 600% (ASTM D412). Expect reasonable variation under field conditions.
How soon can Euclid Eucolastic 1SL be applied to new concrete?
Euclid Eucolastic 1SL can be installed in new concrete 24 hours after forms are stripped. The concrete can be damp during application. Do not apply where there is standing water in or near the joints; excess standing water causes bubbling.
What tack-free time does Euclid Eucolastic 1SL hold at 75 F?
Typical laboratory tack-free time is 7 to 8 hours at 75 F (ASTM C679). Skin time is 1.5 to 2 hours at 72 F and 50% relative humidity. Expect reasonable variation under field conditions.
What tensile strength does Euclid Eucolastic 1SL show?
Typical laboratory tensile strength is 250 psi (ASTM D412). Expect reasonable variation under field conditions.
