Recommended Uses
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 oil or water-based paint. It is also ideal for use in internal timber framing where moisture is a problem, such as in 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.
Limitations
No-Rot Gel will not restore timber severely damaged by rot and termite attack. Unsound wood within any timber structure should be replaced. The new wood must then be treated with No-Rot Gel to prevent deterioration in the future.
Areas Where Decay And White Ant Attack Normally Occur
Decay attacks occur in timber that becomes wet for prolonged periods. Key situations in which timber becomes wet and therefore should be treated with No-Rot Gel are:
- If timber is subjected to long wet periods or high humidity
- Interfaces and joints that trap moisture
- Around drill and bolt holes
Directions For Use
Apply No-Rot Gel to the timber surface using a brush, roller or spray gun. If the timber is very dry, it is best to dampen the timber with water to allow better penetration of No-Rot Gel. For effective treatment against decay, mould and insect attack, use the following table apply the correct dosage to the timber.
| RECOMMENDED DOSAGE RATES PER SQUARE METER | |||
|---|---|---|---|
| Required depth of diffusion into the timber surface | 0-25mm | 25-50mm | 50-100mm |
| Amount of No-Rot Gel required per square meter | 500ml | 1 litre | 2 litres |
For correct dosage rates, No-Rot Gel will require 2 coats. Allow 2-3 hours between coats.
Painting Over No-Rot Gel
Timber treated with No-Rot Gel can be painted over with either oil or water based paints, primers and undercoats. For best results, allow 5 – 8 days for the timber to thoroughly dry.
