Superwool Kaowool Hardner 500ml

Hardener can be applied by brushing, spraying or dipping.  Any spray operation should be carried out in well ventilated conditions and care should be taken to avoid prolonged breathing of the spray.

The amount used varies with application and is proportional to both the depth of treatment and blanket density. 1.7litres will saturate 0.10m² of 25mm blanket. Treatment of thicker blanket can be facilitated by diluting the hardener with up to an equal amount of water.

Drying procedures are not critical but an ideal procedure would take about 12 hours at 60-80°c depending on the size and shape of the treated piece. Drying can be accelerated but to fast a drying rate results in Hardener migrating to the surface.
