Compounds & Chemicals

From concrete pours to paver maintenance, our Compounds & Chemicals category keeps your jobs moving clean and fast. We stock the essentials Long Island and New York City contractors and masons ask for daily, and we keep the brands crews trust. Whether you are sealing a driveway, accelerating a cold-weather slab, or releasing forms on a tight schedule, we can help you match the product to the task.

Types Of Compounds & Chemicals We Carry

  • Concrete accelerators for cold or time-sensitive pours

  • Paver sealers in natural, enhanced, and high-gloss looks

  • Paver cleaners for efflorescence, rust, and general washdowns

  • Construction adhesives, including PL-type interior and exterior formulas

  • Curing compound for proper moisture retention on fresh concrete

  • Form oils for smooth, consistent release on wood or steel forms

Tip from the counter: test cleaners and sealers on a small hidden area first, especially on blended or tumbled pavers, then scale up once the look is right.

Brand Options

W.R. Meadows
Reliable curing compounds and form release options for uniform results. Crews like the consistent film and predictable finish on flatwork.

Alliance Gator
Go-to paver sealers and cleaners that pair well with modern concrete and natural stone pavers. We see strong performance on driveways, patios, and pool decks.

4 Seasons Ties
Jobsite staples and chemicals that support forming and placing. Contractors lean on these for everyday reliability around pours and strip-outs.

Sika
Admixtures and construction adhesives that bond, repair, and speed schedules. Popular for accelerators and structural glues where strength matters.

Simpson
Anchoring and bonding solutions for masonry and concrete connections. A solid choice when you need adhesive performance on dowels and hardware.

Where Compounds & Chemicals Are Used

  • Residential driveways, patios, and walkways, from cleaning to sealing

  • Commercial flatwork where curing compounds and accelerators keep timelines on track

  • Masonry walls and veneers that need strong adhesives and clean prep

  • Forming work that benefits from clean releases and faster turnarounds

Real install tip, straight from our yard: when sealing pavers, wait until the surface is bone dry after cleaning. Moisture under a sealer can haze the finish. If in doubt, give it another day of sun and airflow.
