Best finish for wooden coasters


Recommended Posts

What do you guys think would be the best finish for wooden drink coasters?  I've tried Nitro Lacquer.  Some water makes it through the finish and the coaster cups a teeny bit but then flattens back out when dry.  

I like water white, so I am considering maybe a CAB Acrylic or pre-cat CAB Acrylic.  Could also do Precat Lacquer, but its kinda yellow.  Polyurethane looks too plastic-y.  And using an oil rub doesnt really provide any protection.

I want to do this with the least amount of time and sanding.  I like the nitro lacquer because you dont have to sand between coats and it dries quick.  CAB acrylic would be similar but I dont know if it provides any more water resistance.  I hear good things about Precat Lacquer, but I bilieve you have to sand between coats.

Thoughts?

I have two informal coasters that I have been using for about a year. One is an unfinished piece of walnut, and the other is a piece of cherry half finished with ARS and the other half Osmo Polyx. They are both used most days for hot coffee mugs and for cold water glasses. They both look and feel about the same as when I put them into use. 

My conclusion- I don’t think the finish selection for coasters is as critical as some assume it is.
