Curing Speed vs Traffic Opening Timeline

• After 4-6 Hours: Surface skin forms; resists rain and airborne debris.
• After 24 Hours: Foot traffic allowed; warehouse cleaning operations can resume.
• After 72 Hours: Full mechanical cure; opens to heavy forklifts and rubber-tired vehicle traffic.

Heavy Traffic & Industrial Floors

Where & How SL-100 Self-Leveling Performs

Pourable 1-component polyurethane joint sealant that automatically levels into horizontal concrete expansion and control cuts without tooling or manual troweling.

SL-100 Self-Leveling Sealant Automatic Flow Into Concrete Joint

No Tooling Required

Fast Gravity Self-Leveling Flow

Pour directly from sausage guns or bulk pails into horizontal joints up to 40 mm wide. The fluid paste fills micro-voids and levels flat with the slab surface.

Cuts labor installation time by > 50% compared to thixotropic sealants
Bubble-free curing even under humid concrete slab conditions

Industrial Warehouse Concrete Expansion Joint Filled with SL-100

Warehouse Floors

Logistics Hubs & Industrial Slabs

High-traffic commercial concrete slabs, distribution centers, and manufacturing plants with continuous automated guided vehicles (AGV) and pallet jacks.

Protects brittle concrete joint edges from spalling and chipping
Resists hydraulic oil, brake fluid, and battery acid splashes

Forklift Wheel Traffic Over Cured Concrete Expansion Joint

Heavy Wheel Load

Heavy Forklift Wheel Traffic

Engineered Shore A 35-40 hardness supports solid rubber and hard polyurethane forklift wheels without tearing or permanent plastic deformation.

Withstands up to 10-ton axle load point pressures
Excellent elastomeric recovery prevents joint depression

SL-100 Puncture and Oil Chemical Resistance Lab Test

Chemical & Puncture Test

Chemical & Fuel Immersion Proof

Tested for gas stations, petrochemical plants, airport taxiways, and parking deck joints exposed to de-icing salts, grease, and hydrocarbon spillage.

Meets ASTM C920 Type S, Grade P, Class 25
Resists UV exposure and continuous standing water

Contractor Bulk Estimator: Joint Yield Per Liter

Calculate linear meters per 600ml sausage or 200L drum based on joint width (10-30mm) and depth (10-15mm).
