Shellac/Waterproof edges of laminate particle board

Question

What can I use to seal the edges of utility sink cabinet made from particle board?

I had a bad cartridge and water leaked and destroyed the edges—the laminate is separating. I am starting with a new cabinet and would like to protect it.

Thanks.

Answer 1

I treat the cut, or sawn, edges of particle board when they are in areas that are likely to get occasionally wet. I use a "heavy" varnish.

However, that damage was to a "sealed" edge and I would not have varnished that.

If the cabinet will suffer more frequent wetting then use different materials instead of particle board. How about some plastic - that can be had in similar thicknesses. And it should be able to provide sufficient support to the door so should look "ok".
