Thin coatings remediation

When waterlogged wood is treated with PEG and stored or displayed in areas with high relative humidity, the low-molecular-weight fractions tend to bleed from the surface. A number of coatings have been used to arrest this accumulation of low-molecular-weight PEG on the surface of artifacts. The most common remedy is to apply a thin coat of molten high-molecular-weight PEG to the surface of the object.
