UNISOFT - 2 part wood filler, easy to sand, suitable for a very wide range of use. Applied in thick layers it is excellent for filling large cavities. It produces a soft surface, suitable both for manual and machine sanding. It has very good adhesion to various substrates, including galvanised steel. It is highly elastic, which minimises the risk of cracking, even when applied on large surfaces. Rapid curing reduces the time of repair.
