Structural Adhesives

Below are some questions about timber repair and our associated products

What are resin repairs and what arethey 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 are the benefits of structural timber resin repairs?
  • What are the benefits of structural timber resin repairs?
    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.
Do you have to remove all the rot?

Yes, all rot must be removed

How do I treat dry rot?

Replace affected timber either with one of our timber repair methods or with pre-treated timber section and then treat remaining sound timber with a fungicide. 

Can the resin be painted or stained?

Yes, our structural adhesives can be painted once fully cured

How soon can you paint the repair?

Our products have varying cure schedules so please refer to the specific product datasheet

Will temperature affect the cure schedule?

Yes, extreme temperature fluctuations will affect the cure schedule, please refer to the specific product datasheet for further
information.

What materials can I use for repairs?

You can use a structural adhesive, a structural timber grout or for cosmetic repairs, use a moulding mortar. It will all depend on the nature of the damage. 

How do I fix a split in wood?

Apply adhesive to the split, clamp the pieces together, and allow the adhesive to cure. 

Can I use Rotafix StructuralAdhesives to fill large holes?

No, we wouldn’t advise using a structural adhesive to fill large voids. Please refer to our TG6 Timbergrout product. 

Are the products safe to use?

Epoxy resin products are classified as skin irritants. Avoid skin contact by wearing Nitrile gloves. When appropriate wear eye protection. Full details are available on the product data sheets.

Grouts and Mortars

Below are some questions about damp proofing and our products

What is a damp proof membrane (DPM)?

A DPM is a moisture-resistant barrier that prevents dampness from entering a room/building, acting as a shield against rising damp, penetrating damp, and condensation. Our Aquachem product is 3-coat system comprising of a primer base coat and topcoat application.

What is the purpose of a damp proof membrane?

The primary purpose is to prevent moisture from damaging
buildings and their contents by creating a barrier against water.

Can I apply Aquachem over an oldconcrete floor that already has some damp issues?

Yes, in most cases, you can apply Aquachem to an existing slab if you prepare the surface properly, please refer to datasheet for preparation instructions.

How is Aquachem applied?

Aquachem can be applied using a spray, brush or roller and works optimally when applied as three thin coats. It can be combined with flakes to create decorative finishes and aggregates to create slip resistant surfaces.

How long does Aquachem take to dry?

Drying time varies, but it typically takes 12-24 hours, depending on temperature, humidity, and thickness. Please refer to the datasheet for specific cure schedules.

Can I use Aquachem under concrete, rubber flooring and other substrates?

Yes, Aquachem works well under concrete, rubber flooring, tiles, or foam finishes, preventing water ingress.

Is Aquachem safe to use?

Yes, once fully cured and dried, Aquachem is safe. Aquachem is water based and solvent free making it ideal for treating confined areas such as basements, cellars and loft spaces.

Suitable for most under floor heating systems.

Hygienic coating for food preparation areas such as dairies, factories, warehouses, and is safe for aquatic life and potable water tanks as it is ‘Water Board’ certificated.
