Can You Use Resins on Old Fischer Fixings?

Why Reinforce Old Anchor Fixings?

Over time, anchors may loosen, especially if the surrounding material has deteriorated or been exposed to stress. Injecting or applying a suitable resin can dramatically boost adhesion and restore or even increase load capacity. Both polyester and epoxy resins provide robust, durable bonds on rigid materials and are commonly used to rejuvenate ageing fixings.

Choosing the Right Resin System

Selecting an appropriate resin is vital for the best long-term result. For structural reinforcement on rigid surfaces such as concrete, brick, or metal, a Resin Fibreglass Repair Kit with a polyester resin base is a strong choice, offering durability and a waterproof finish. Epoxy adhesives like “FixExpress” are quick-setting and especially useful for multi-material repairs or where rapid results are desired. For advanced needs, such as fibre reinforcement around anchor points, specialist composite resins further improve strength and reliability.

• Always clean and prepare the area around the old anchor before applying resin
• Follow the product’s mixing and application instructions for optimal bonding
• Allow sufficient curing time before applying loads

When This Matters Most

Resin reinforcement is particularly relevant when you cannot remove and replace old Fischer fixings—such as in structural repairs, listed properties, or when carrying out upgrades where demolition isn’t practical. It also serves if anchor strength is critical for safety or load-bearing purposes.
