Chemicals for Professional-Grade Masonry Projects
At 9 Brothers Building Supply, we offer a diverse and reliable selection of chemicals designed specifically for masonry and construction applications. Serving Long Island and NYC, our Brentwood and Riverhead locations are stocked with top-performing products from industry leaders. Whether you're a seasoned contractor or a DIY enthusiast, our chemicals ensure your project’s durability, precision, and success from start to finish.
Comprehensive Range of Masonry Chemicals
The effectiveness of any masonry project goes far beyond stone and mortar. The right chemicals are essential to maintain structure integrity, accelerate processes, and protect surfaces. Our inventory includes high-performance solutions from trusted brands like Sika and W.R. Meadows—well-known for reliability in the field.
From Sika, we carry:
Sika Level-01 Primer Plus – Ensures optimal surface preparation and enhances the bond for overlays or coatings
Sikaflex 15LM Limestone – A premium joint sealant that accommodates movement and resists cracking
Sikaflex-1c SL – A self-leveling joint sealant ideal for expansion joints and professional-grade finishes
From W.R. Meadows, our product line includes:
100 Curing Compound – Promotes proper concrete curing, which increases long-term strength and reduces cracking
CS-309-25 OTC Sealer – Seals concrete surfaces for lasting protection against moisture and abrasion
VOCOMP 20 – A versatile, water-based curing and sealing compound for multiple use cases
These chemicals are selected for their performance, longevity, and ease of use, ensuring the quality of your project from the foundation up.
The Value of Using the Right Chemicals
Using the correct chemicals significantly impacts the longevity and performance of your construction or masonry work. Curing compounds and sealers protect against environmental wear, water infiltration, and structural degradation. Joint sealants ensure flexibility where expansion or movement is expected, preventing unsightly or dangerous cracks.
Whether you're building a patio, pouring a commercial slab, or completing a residential walkway, choosing high-quality chemicals enhances both durability and appearance. These products reduce maintenance costs and improve overall results—making them indispensable on any jobsite.
