Rewah

What Rewah does

Rewah NV is a privately held Belgian specialty manufacturer of construction chemical products, founded in 1985 and headquartered at Nijverheidsweg 24, 2240 Zandhoven, Belgium, where it also operates its manufacturing facility. The company develops, produces, and sells a portfolio of approximately 50+ SKUs across seven product pillars: waterproofing (rising-damp injection, salt treatment, cellar drainage/sealing), facade restoration (cleaning, paint stripping, stone hardening, natural stone repair, lime products, facade protection), roof renovation (wood restoration, cleaning, coatings), paints (primers, exterior/interior paints, kalei systems), concrete repair (mineral and epoxy mortars), industrial products (mortars, leveling compounds, floor protection, curing compounds, steel/PP fibers, temporary protection), and tools (measuring equipment, color fans). Notable technical differentiators include ethyl-silicate (TEOS) stone consolidants that form amorphous quartz within substrate capillaries, water-based solvent-free paint strippers, and self-cleaning facade treatments, with ATG certification held for Rewagel Inject 3A+ and IRPA/KIK certification for monument-conservation applications.

The business model is exclusively B2B, serving professional customers through two channels: approved wholesalers (grossistes agréés) for paint products and direct engagement with specialized renovation, waterproofing, and industrial-application contractors. Distribution is supported by a regional technical-advisor sales force organized by Belgian sub-region (Flanders, Wallonia, Brussels) and the Netherlands, with dedicated specialists for restoration/waterproofing, painting, and industrial applications who provide on-site job consultation and specification support. Customer segments include waterproofing specialists, facade restoration contractors, roof renovation contractors, paint application professionals, industrial construction firms, monument conservation specialists, and concrete repair specialists. Documented end-use projects span religious heritage sites (Sint-Pieterskerk Berlaar, Sint-Salvatorskathedraal Brugge, Zuiderkerkstoren Amsterdam, Onze-Lieve-Vrouwekathedraal Antwerpen, Red Star Line Museum), industrial facilities (Hygiena food distribution, ROB production, Brussels Expo Palais 10), and infrastructure (Port of Antwerp Deurganckdok, Zaventem Airport). Revenue, pricing, and headcount are not publicly disclosed; the company is privately held with no disclosed external investors, parent company, or M&A activity.

Direct peers

• KEIMFARBEN (KEIM): German mineral silicate paint manufacturer specializing in breathable coatings for heritage and historic buildings. Highly comparable in the lime-paint and breathable coating segments (overlapping with Rewah's Kalkverf Calciana and Kalei Liscio 2 lines) and in serving monument conservation customers.
• Remmers GmbH: German specialty manufacturer of construction chemicals with deep focus on building restoration, waterproofing, facade protection, and wood preservation. Most directly comparable peer — similar heritage-led positioning, similar product breadth across restoration/waterproofing/coatings, and similar specification-driven B2B go-to-market.
• Beeck'sche Farbwerke (Beeck): German manufacturer of mineral paints and silicate coatings engineered for historic buildings and natural substrates. Comparable in heritage/monument restoration chemistry and breathable coating technology, similar in scale and customer segment focus.
• Cantillana NV: Belgian manufacturer of construction chemicals and mortars serving Benelux professional markets. Direct geographic and product-line overlap with Rewah — both serve Belgian contractors with waterproofing, mortars, and facade solutions through wholesale and professional channels.
