TM3 Moulding Repair Mortar

Rotafix TM3 Moulding Mortar is a 2-part moulding mortar specifically designed for repairing wood and stone.

The Mortar is an epoxy repair putty that can be used to replace damaged wood in window frames or ornate carvings. It will not shrink once it has cured.

Once cured Rotafix TM3 can be shaped, sanded, stained, painted or varnished to blend invisibly with the parent substrate. It can be a cost effective method of repairing shaped wood and stone carvings and profiles, ensuring that as much of the original feature is retained.

A lightweight mortar with very little slump

Rotafix RM20 LW is a lightweight concrete repair mortar which is suitable for repairs to reinforced concrete structures.

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.

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.
