Degrease Surfaces with the Appropriate Degreaser

Prior to sanding, ensure that the surface is clean and well degreased.

Loose and water soluble dirt may be removed with warm water and ammonia.

By degreasing before sanding, grease and contamination will not by sanded deeper into the sanding scratches. Degreasing should exclusively be done with multiple clean towels, turning and replacing regularly to prevent contamination.

Allow sufficient time to evaporate and the surface to fully dry.

Always use the appropriate degreaser:

Bare Tropical Wood (e.g. Teak): Epifanes Spraythinner for P & V or Epifanes Thinner for PP Varnish Extra

Take personal safety precautions when degreasing and wear protective gloves, protective clothing, eye and face protection.
