RotStop Multi-Spectrum Timber Treatment

Safe boron salt-based, multi-spectrum timber treatment.

Boron salts have been used to safely treat timber for NZ houses since 1952. Boron continues to be used today in all H1.2 treated timber.

Extensive testing shows that boron at high enough concentrations controls most species of fungi for short term leaks.  However, some species are not managed and once decay has established, boron alone does not stop them from spreading. Boron does not protect against long term leaks.

RotStop, formulated with additional fungicides,  controls many types of decay, including brown rots, white rots and wet rots.  The treatment soaks deeply into the timber, aided by surfactants and penetrants.

Houses with long-term leaks, or poorly treated timber are being damaged by decay, which can be prevented with RotStop. 

RotStop Process To Treat Timber

Non-disruptive, safe treatment process

RotStop injection is through small holes in the external cladding or gib.  These are repaired following treatment.

An injection programme typically takes four to five days, including repairing any drill holes in the cladding with a strong resin-based plaster repair system.

Occupant do not  need to leave the house while we treat the timber.

We inject RotStop as either a foam (into wall cavities) or a liquid (directly into studs).  Exposed framing can be treated with a direct topical application.

Treat Timber That Needs Treating

Save money by effectively targeting treatment at known problem areas

Just putting RotStop timber treatment into a house without knowing exactly where the problems are?  It’s like firing a shotgun into the air and hoping to hit a duck. Maybe you will be successful, but more likely you will not be treating the real problems.  Treating areas that are not at risk is a waste of money.

A RotStop treatment programme is usually planned following installation of an Mdu Moisture Probe System.  Using the detailed information on the existing timber treatment, moisture contents and decay condition at the leak risk points around your house, our experts recommend a treatment plan in line with your goals, and the needs of the house.

If you have just one or two areas where you know there is a leak, we can just treat those for you.

RotStop is part of an overall process to make your house safe and dry.
