Preparation - Beetle Infestations:

Ensure that all timbers to be treated adequately exposed and cleaned, (vacuum cleaning preferred). Any paint or varnish finishes or any severely damaged sapwood edges of timbers (‘frass’) should be removed prior to treatment where possible.

Remove thermal insulation in roof spaces (or roll up and completely cover) and do not reinstate until timbers are dry.

Cover fitted insulation (lagging on pipes) with polythene and cover water storage tanks with heavy grade polythene to be left in-situ after treatment.

Isolate electrical circuits in the treatment area during and for 8 hours after treatment and ensure that junction boxes etc. are adequately protected against the ingress of the fluid. Remove or cover all food-stuff before application as well as fish tanks / bowls.

Do not apply to surfaces on which food is prepared or stored.

Where applicable, notify occupants of adjoining properties before treatments commence.

Display Safety Notices conspicuously during treatment and leave on site after treatment for at least 48 hours.

Preparation - Fungal Decay - Dry Rot / Wet Rot:

Same as (Beetle Infestations) above plus - locate and rectify the source of dampness.

Cut out all structurally unsound timbers and make repairs isolating timbers where possible from damp masonry etc. and ensuring adequate ventilation.

For treatments of decayed timbers in-situ see Wykabor 40.1.

Application Method:

Uses: Yacht decking, House decks-patios etc. Fencing, wall coverings. Furniture - outdoor hardwood and softwoods.

Wear suitable protective clothing (coveralls), synthetic rubber / PVC gloves when using N-Virobor 10.

Teak decks and outdoor furniture.

This treatment should be carried out annually on exterior decking and teak / wood furniture to prevent slime, mould, algae, insect and wood rot attack.

Wash to remove all dirt and previous coatings. Allow the surface to dry until just damp. Apply a single coat of N-ViroBor 10 by brush or spray until the surface is visible.

Allow the surface to dry out until just damp again. Then apply a second coat of N-ViroBor 10.


By Brush / Spray: 1 litre per 4m² of wood or masonry surface.

By Dipping: Approx. 5 - 20 litres/m³ (dependant on timber dimensions etc).


As long as timbers are dry, re-occupation can normally take place 48 hours after treatments are completed.

Floor coverings should not be laid for at least 72 hours (or longer for certain impermeable or other floor materials, e.g. Vinyls, foam-backed carpets etc).

In all cases, use lining papers to protect coverings from direct contact with timbers. Treated timbers can be over coated when dry with a range of decorative / protective paints etc. (to ensure compatibility check a small area first).
