Walther Strong And Company

What Walther Strong And Company does

Walther Strong And Company is a privately-held UK manufacturer of premium, application-specific tapes, adhesives, silicones, and protective coatings for the construction industry, founded in 2012 by Managing Director Fred Dunn and headquartered in Grantham (with offices referenced in Stamford). The company is best known as the pioneer of the deck tape category, having engineered the first tape purpose-built to protect timber decking subframes from moisture, rot, and fastener-driven water ingress; its flagship Deck Tape is now in its 12th continuous edition and is backed by a 25-year bond guarantee. Product technology centres on a proprietary non-butyl polymer acrylic adhesive with UV-stable, weatherproof, self-sealing performance tested to 50+ year durability under accelerated aging, complemented by liquid masking solutions (H20 Liquid Mask), low-modulus silicone sealants (Silicone Pro4, Rilicone), construction adhesives (Allcon10), reinforcement meshes, and acoustic/cleanroom specialty tapes. The portfolio is certified to ISO 9001, ASTM, AAMA 711-07 Level A, DIN, ISO 11600, DIN EN 15651, GEV-EMICODE EC 1Plus, and VSG standards.

The business model is product-led direct-to-consumer e-commerce supplemented by a UK merchant and trade-counter network (formalised through Find a Merchant and Become a Stockist programs), with bulk/box pricing for trade accounts and international shipping on inquiry. Customers are segmented vertically across landscaping, painting and decorating, plastering and rendering, building and construction, and arts and crafts — primarily SMB trade professionals, with named reference installations including IKEA HQ and Blackpool Pier. The company distributes to 16+ countries, has cumulatively supplied 48+ million linear metres of Deck Tape, and markets actively through SEO content, social media (Facebook, Instagram, YouTube), email, and trade events such as the Painting & Decorating Show 2026 at NEC Birmingham, where it partnered with Graco. Sub-brands BEKO, Rilicone, and Alkamaxx extend the platform beyond the original tape category into silicone sealants, accessories, and complementary construction chemicals.
