Engineering Adhesive

Rotafix Engineering Adhesive(EA) is a high strength structural epoxy adhesive, part of the Resiwood product range. The two part unfilled epoxy glue has a degree of flex which makes it well suited to wood engineering and timber applications.

The slow setting nature of the Engineering Adhesive(EA) epoxy adhesive lends itself to working on site where you need time to create and move joints before finalising the assembly. Engineering Adhesive(EA) is a thick film adhesive that cures without the need for pressure or additional heat being applied during the cure. This makes it an ideal adhesive for on site construction as no specialist equipment is required.

Engineering Adhesive is well suited to :-

  • Timber engineering, 
  • Timber resin splice
  • Timber joints. 
  • Stressed skin floors. 
  • Rod and Resin repairs, such as the Rotafix methods and Resiwood approach
  • Wood Engineering and Timber Construction

Rotafix Resiwood Engineering Adhesive has additives that give the epoxy glue a degree of flex and movement. Where brittle adhesives might crack and break up, Engineering Adhesive will move and retain its strength. This is important where there is likely to be variable loading of the structure or where there will be fluctuations in the temperature or the humidity of the environment.

Ideal for on-site construction work

Rotafix's strengthening techniques were invaluable to the project by ensuring the complex remained open throughout the repair works and the aesthetic of the exposed timber frame was retained.

Additional Information

Available Sizes
  • 400cc (Product code: 3560)
Product Coverage

As a guide, a 400cc pack of mixed Rotafix® Engineering Adhesive with an adhesive thickness line of 1mm will cover 0.4m² of timber.
As a guide for crack injection 400cc pack would inject 5 linear meters of a crack 3mm wide x 25mm deep.

How to use

Add the total contents of the smaller container (curing agent) to the base. Mix the pastes thoroughly using a flat end palette knife, reference 3642. To give a homogeneous one colour mix.
Place the Follower-plate onto the surface of the mixed material, ensuring it fits parallel in the tub with the outer and central lip pointing upwards.
Cut the seal from the front end of the cartridge sleeve. Place the back of the cartridge vertically and centrally over the hole in the follower plate.
Press the cartridge firmly and continuously down onto the follower plate until the follower plate bottoms on the mixing tub base. Carefully remove and invert the now full cartridge.
Screw on the front injection nozzle plus any chosen injection tube assembly. Finally, insert the rear plunger.

Where applicable, install the full cartridge of Rotafix® Engineering Adhesive into the injection gun.
Alternatively, for spreader application as an adhesive, dispense directly from the cartridge without the aid of the front nozzle or injection tube.

What are resin repairs and what are they used for?

Resin repairs are used to repair or strengthen timber within a building. Our adhesives, grouts and mortars are workable to pump, pour and mould and can be used for a whole range of repairs due to their versatility. They are mostly used within structural timber repairs because of its strength and non-porous composition that makes a tight bond with any timber elements. Damp affected timbers soon start to rot and lose their structural integrity, therefore, it is important to remove affected timbers and rebuild the structure. Timber resin repairs can offer a cost-effective solution by repairing only the damaged area instead of replacing the whole timber structure.

What types of repairs are there?

For structural timber repairs there are several types of repairs we may suggest. After speaking to one of our technical experts, we will assess which of these repairs will be the most effective to solve the property problem. Some of the most common types of repairs for structural timber damage include:

  • Solid Resin
  • Timber Resin Splice (TRS)
  • Crack and Shake Repair
  • Joinery & Cosmetic
How do I know if I need timber resin repair?

The truth is, you may find it difficult to identify whether you need a timber resin repair. If you have noticed rot affected timber within your property, then it’s clear that the affected area needs to be treated. Using timber resin repair systems is one of our rot repair options, but it should only be specified by a professional property surveyor.

If you believe that you have structural timber damage, please call and speak to one of our technical experts to assess the problem and identify the most effective course of action.

What types of repairs are there?

Resin has long been used for structural timber repairs because of the benefits it provides and its effectiveness in timber repairs. Some of the benefits of resin repairs are:

  • They minimise disturbance – Using resin repair means that you can retain existing ceilings and floor fabric but still make an effective repair to the structural timbers. Many other types of timber repair will involve demolishing much more of the property to get access for the repair, often leaving the property uninhabitable for longer and costing more for the repair.
  • Keep your building in use – With other types of repair whole sections of a building are often exposed and unable to be used. A resin repair will only need to expose the localised area.
  • Retain the structure – Resin repairs aim to save the existing timber through repair of the rot affected timber only.
  • Durability – Resin is resistant to moisture and therefore minimises the chances of a future fungal attack.
  • Match exposed timber profiles – Ornate exposed structural timbers can be repaired to match the existing profile.
