Three Preservative Types (Junior Cert Wood Technology): Flashcards

Substance that keeps wood safe from decay, insects & damage

Uses oil to soak into & protect wood

Preservative with water as primary solvent

Uses organic solvents to thin chemicals for wood protection

Oil seeps into wood fibres for deep protection from within

Protects against fungi, insects & weathering

Marine wood & utility poles (deep penetration)

Oil spills, toxic runoff, limited use in sensitive areas

Includes copper or biocides for barrier protection

Less toxic than oil-based, safer for residential use

Household items like furniture

Can leach in wet areas, needs frequent reapplication

Bonds with wood, prevents biological & environmental damage

Long-lasting protection in harsh environments

Highly volatile, pollutes, health risks if used improperly
