How to stop wood from rotting?  Not Rot Gel is a ready to use, water based brush on wood preservative, to control the spread of decay.

It is formulated to penetrate by diffusion into the timber, while still allowing the surface to be painted over. It can also be used to kill surface mould, algae or fungi. You can use No Rot Gel on timber, masonry or concrete surfaces.

No-Rot Gel can be painted over, used indoors or outdoors (but must be painted over) and will penetrate through patches of decay killing it and treating the sound wood behind it.

Available in 1L, 5L, 10L, and 20L.


No-Rot Gel can be used as a timber treatment where it has been affected by decay, mildew or insect attack. No-Rot Gel is ideal for use in external areas such as timber window frames and posts that are intended to be painted with an oil or water based paint. It is also ideal for use in internal timber framing where moisture is a problem, such as bathrooms or under subfloors with poor ventilation.

RESTRAINTS. No-Rot Gel is not to be used on timber exposed to rain (ie without a painted finish or surface coat), timber in contact with the ground, or surfaces that come into contact with foodstuffs or drinking water.
