Sinto SA

What Sinto SA does

Sinto SA is a French manufacturer of multi-material repair and renovation products, founded in 1947 and headquartered in Aubagne, France, operating as a subsidiary brand under the holding company Brunel Chimie Dérivés (registered in Wasquehal). The company produces bi-component polyester mastics and epoxy formulations organized across material-specific sub-brands: Sinto Bois (wood fillers, mastics, adhesives, hardeners), Sinto Fer (metal cold-welding epoxies and mastics), Sinto Pierre / Sintopierre (stone and masonry mastics and chemical anchoring), Sinto Marine (water-contact gel coats and polyester mastics), and Sinto Peinture (aerosol paints, high-temperature coatings up to 650°C, sanitary and kitchen epoxy paint). A separate Sinto Pro line covers professional-grade wood, metal, stone, multi-material repair, anticorrosion and maintenance paints, marking and tracing aerosols, and accessories. Distinctive technical features include a chemical anchoring resin with a blue-to-grey color-change cure indicator for load-bearing readiness up to one tonne in concrete, rapid-cure epoxies (5-minute set on Répare Vite métal), and a deep-penetrating epoxy wood consolidator for humidity-damaged substrates. All bi-component mastics share a common Durcisseur hardener, creating chemistry platform consistency across the portfolio.

The company serves two primary customer segments: individual DIY consumers performing home repairs, and trade professionals including painters, metalworkers, cabinetmakers, carrossiers, and joiners. Revenue is generated through one-time unit purchases across both consumer (€3.80-€27 retail price points) and professional (cartridge and bulk formats) product lines. Go-to-market is a dual-channel model: specialized hardware stores and the Starwax & Co e-commerce platform address the DIY consumer segment, while a dedicated professional distributor network addresses trade buyers. Brand awareness is reinforced by an extensive DIY advice blog with step-by-step tutorials and a toll-free customer service line (0800 09 2000) for technical support, creating a content-led top-of-funnel motion that feeds the retail and e-commerce channels. The company is CLP-compliant, participates in the Eco DDS recycling scheme, and publishes Safety Data Sheets via the Quick-FDS regulatory platform.

Geographically, Sinto operates within the broader European market but its distribution footprint is described as single-country/domestic France, with no confirmed international expansion in the available data. The company is privately held under Brunel Chimie Dérivés, with no venture capital, private equity, or public ownership signals, and employs 11-50 people.

Core offering

Sinto SA manufactures and markets a range of bi-component polyester mastic and epoxy-based repair, maintenance, and protection products for wood, metal, stone, water-contact surfaces, and multi-material applications. The portfolio is organized into sub-brands (Sinto Bois, Sinto Fer, Sinto Pierre, Sinto Marine, Sintopeinture) and sold in both consumer/DIY and professional/industrial formats across France through hardware retailers, professional distributors, and the Starwax & Co e-commerce platform.

Product overview

Sinto SA is a French manufacturer of multi-material repair and renovation products founded in 1947, operating as a portfolio of specialized product lines under distinct sub-brands. The portfolio is organized by material type: Sinto Bois (wood repair fillers, mastics, adhesives, and wood hardeners), Sinto Fer (metal repair products including cold-welding epoxies, mastics, and fillers), Sinto Pierre (stone and masonry repair mastics and chemical anchors), Sinto Marine (water-contact surface repair including gel coats and polyester mastics), and Sintopeinture (aerosol paints, high-temperature coatings, and sanitary/kitchen paints). The professional range (SintoPro) provides higher-volume and industrial-grade versions of core products. Products are formulated as bi-component polyester or epoxy systems requiring a hardener additive (Durcisseur), which is a cross-cutting accessory across all material lines. The offering spans from consumer/DIY products (smaller packaging, ready-to-use formats) to professional/industrial solutions (larger volumes, cartridge and bulk formats, technical grades). The company also offers complementary accessories (abrasives, tapes, dosing tools) and a full marking, tracing, and maintenance product line for professional users.
