This large family of finishes has a common trait of having the solids suspended in water which is used as the solvent. A clear, color free finish available as a one part, cross-linked or as a two-part. Products using a cross-linker (catalyst) may have enhanced stain and abrasion resistance. Easy to apply with low odor and good stain resistance, but may raise grain during first and second coat. Fast drying and easy to recoat.
