Lacquer is widely known for its ease of application and short drying time. It’s the most used wood finish commercially. Its primary component is the resin of varnish trees. After harvesting and refining, the resin is mixed with thinner to create lacquer.

Lacquer:
* It’s compatible with various solvents.
* It doesn’t show yellowing over time.
* It’s relatively affordable.
* It looks sleek after application.
* It has low resistance to chemicals.
* You have to apply it again year after year.
* If it gets contaminated, defects will appear on the wood.
* If the room’s temperature is too warm, bubbles will appear.
* It’s harmful to the environment.

Polyurethane is a​ sealant that provides exceptional durability on wood surfaces, and is available as both a water-based sealant and an oil-based sealant. Polyurethane is very durable – some label it as “liquid plastic” while its still in the tub, because when it dries it will turn as hard as plastic.

Polyurethane:
* Water-based or oil-based
​* Slow drying
​* Matte, satin, glossy, and high gloss finish
​* Very strong sealant
* Provides a shiny look when dry

Varnish is a clear protective finish. Varnish has little to no color and is primarily used in wood finishing applications where the final product will be in harsh conditions, such as sun or water. It can be applied over wood stains as well.

Hi, thank you for this video. Very useful. I started a dining table project and I’m in the process of finishing it. I’ve put three coats of Ronseal interior varnish but I realised I should have used polyurethane. Can I put polyurethane on top of varnish? Will it ruin the table?

I have a mango wood table which has been finished with a flat lacquer. If i want to keep it outside, can i use spar varnish over it to protect against UV, termites, mold, or is there another method which might work? Thanks for any tips.

Hi. THANKS for a great video.
This is a jungle ;-)
One question: Can you use polyurethane on top of e.g. Danish Oil or some other oil product like Osmo oils?

Great! What is shellac then, and how does it compare? What do we use on antique furniture made with mahogany veneer, and do we wax all wood furniture once in a while to maintain the finish? I'm still a bit confused. My parents' antiques get waxed but the finish is shiny.

Ok…if I’ve already put 3 coats of beautiful lacquer on but want to switch to varnish, can I put the varnish on over top lacquer or do I have to strip it right down and start over? I hope it’s the first answer.

I have an unfinished magnolia wood handle on a Japanese chef knife. I would like to seal it, so I don’t have to constantly oil it. What type of varnish/lacquer would you recommend?
