Finishes = 面漆
Varnish = 清漆
Clear-coat = 透明層(just a layer that is clear)
而透明油有好多種類去應付唔同需求。
Varnish:
Oil based varnish is a relatively tough air drying clear coat that is chemically resistant. Most varnishes have excellent adhesion, but will yellow to a greater or lesser degree over time. Designed for outdoor projects and is not typically used for indoor surfaces such as a hardwood floor.
(力架)Lacquer is a type of coating. it can be clear or pigmented. so can enamel, acrylic, urethane, and any other types of coatings/paints.
Lacquer:
Thin and penetrates the wood surface. It is also durable but susceptible to scratches and discoloration after some time.
Polyurethane:
more durable. It is thick and leaves a strong coating, but they have poor adhesion, dry slowly, and yellow a great deal over time.
Shellac: 蟲膠
Used as a finish and a sealer under varnish because of it’s fast drying properties. Shellac has a naturally occurring wax in it that will repel some finishes used over the top of it.

首先,不如唔好咁執著。
最大路係用varnish, 而varnish包左好多種。
Enamels = 硝基 = 琺瑯油 = 磁漆 They tend to be very durable, but their odor can be strong, and many find them unsatisfactory for that reason. If applied carefully, they can be used as a clear coat for most mediums, though I have seen cases where a heavy-handed application reacted with previous enamel coats in a bad way.
Lacquer = 力架 = 合成樹脂力架油 They tend to go on very, very smooth, smell awful, and of the three types discussed here, generally have the highest probability for a bad reaction with previous layers if you’re not experienced in their use. (And they can eat Bandai plastic alive if you’re not really, really careful.)
1K 光油係Universal Varnish
1K係指得1 part component, 無activator。
2K係指有2 part component, 有activator。
而兩隻光油都係polyurethane,各廠商可能成份唔同,有water-based,亦有solvent-based.
