What Silpro does

SILPRO is a US-based specialty construction materials manufacturer founded in 1951 and headquartered in Ayer, Massachusetts, with manufacturing and warehousing operations in Kent, Washington and Cleveland, Ohio. The company designs, formulates, and sells polymer-modified cement-based products—including calcium aluminate cement formulations, Portland cement-based coatings, and hydraulic cement technologies—organized across 13 product categories spanning skim coats, thin and thick repair mortars, self-leveling cements, vertical/overhead mortars, decorative exterior finishes, waterproofing coatings, grouts, hydraulic plugs, polymeric sands, bonding agents/admixtures, and sealers.

The company's product portfolio is anchored by 20+ registered trademarks such as Skim Pro®, TDQ™, Patchco®, Raeco®, Silflo®, SilproGrout®, Fastcrete®, and Easy Plug™, with differentiated performance characteristics including rapid cure times (flooring installable in 30 minutes; vehicle traffic in 1–3 hours), high compressive strength (up to 5,150 PSI), and freeze-thaw resistance suited to demanding infrastructure applications including DOT bridge deck and highway overlay repair.

SILPRO operates a hybrid distribution model, selling through a network of distributor partners alongside direct engagement with flooring, masonry, and concrete repair contractors, with technical support and personalized service positioned as core competitive advantages. Revenue is generated through transactional unit-pricing of bagged and pail-packaged products (10–50 lb formats), with no subscription or recurring contract model. The company serves professional contractors across three primary segments—flooring, concrete repair, and masonry—in the United States only.
