Bend with the changes

Slab® is extremely elastic and will adjust with your concrete even when it moves with shifting soils, temperature, moisture, or traffic over the years.

Sticks it out longer

Slab® is specifically formulated for unbreakable adhesion to concrete. The balance of elasticity and adhesion means that your sealant will last for years, not just months.

Textured like concrete to blend in seamlessly

Why put a shiny caulk in concrete? Eye-sore! Slab® doesn’t just repair the crack, it matches your concrete.

Technical Info and Safety Data Sheets

Step outside and you’re likely to see a concrete crack in less than two seconds flat. They’re in driveways, sidewalks, garages, patios, pool decks, and basements. Cracks harbor weeds and anthills, and cause toe injuries (ouch!). They’re eyesores that never seem to go away. Changes in temperature, moisture, shifting soils, and traffic only make them worse. Enough is enough! Just say no to cracks. Slab® is an easy-to-apply water-based sealant that really stretches up to 300% of original crack size! To create a permanent, weatherproof repair that stands the test of time. Your knees and back will thank you for using a product that won’t require repeated repairs year after year. Slab® sticks, stretches, and stays to banish concrete cracks for good.

Slab® is perfect for repairing large or small cracks in concrete, brick or stone including: 

  • Sidewalks
  • Garages and sheds
  • Driveways
  • Patios
  • Horizontal expansion joints
  • Basement floors
icon others surfaces
Slab® adheres to:

asphalt*, brick, cinder block, concrete, EIFS, mortar, stone, stucco, wood

*Be aware that asphalt is a weak substrate. Slab will hold its seal, but the asphalt may lose adhesion to itself over time.

Where not to use

There are only two rules of the Slab club:

Is it old enough to Slab? Concrete that is less than 6 months old, or hasn’t fully cured will not bind well with Slab.

Take caution: slippery when wet. Slab won’t stick to concrete that is constantly submerged in water or that is prone to frequent, prolonged puddling, or where hydrostatic resistance is wanted.
