The purpose of the protective coating is to slow down the rate at which the timber will take up or lose moisture. By slowing that rate down, the severity of any checking is considerably reduced. The coating should contain a fungicide to prevent mould growing on any sugars or starches that may be in the coating.Avoid using any tools which may deposit fine iron filings on the timber surface. interior wall paneling in the MalaysiaAny iron filings which are not cleaned from the surface are likely to create unsightly black staining of the timber.
