Sapstain, sometimes called blue stain, and mould is caused by fungi which thrive on freshly cut logs and sawn timber causing unsightly discolouration. Infected timber is unacceptable for many end uses, representing a huge loss in value.
Once sapstain infection has discoloured the wood it is not practically possible to remove the stain. Hence the only practical treatment for sapstain fungi is prevention. Antiblu® protects against staining, helping to maintain the commercial value of timbers.
