Concrete Accelerators Products

Concrete Accelerators in Long Island and NYC

When cold weather, tight schedules, or fast turnarounds are on the table, concrete accelerators help you keep pours moving without waiting around. We see contractors use them to hit morning strip times and keep crews productive, and homeowners use them for small slabs, steps, and repairs that need to set up faster. At 9 Brothers Building Supply, we help you pick the right accelerator for the conditions and the mix, and we can get it on your truck fast from our Brentwood yard.

What We Carry

Concrete accelerators come in a few common forms, and the right choice depends on temperature, placement, and finish requirements.

• Non chlorinated accelerators for general flatwork and reinforced concrete jobs

• Chloride based accelerators for applications where rebar corrosion is not a concern

• Cold weather set accelerators for pours that need a faster set when temps drop

• Additives that pair well with certain bag mixes and repair mortars

If you already have a mix design, bring it in or tell us what you’re pouring. Our counter team can help you match the accelerator to your job so you get workable time and the set you need.

How People Use Concrete Accelerators in Long Island and NYC

Contractors lean on accelerators for sidewalks, curbs, stoops, garage slabs, footings, and patch work where the schedule is tight. Homeowners typically use them for small projects like shed pads, step repairs, and fence post work, especially when temperatures swing.

Real tip we give all the time, don’t use an accelerator as a substitute for good cold weather practices. Protect the pour. Keep materials out of the wind, cover the slab, and plan curing. Also, measure carefully. Over dosing can shorten working time and make finishing a headache.
