Repairing water effected older particle board cupboard doors caused by Mop Sloppdoors

Has anyone any clues how to seal the bottom edges of older particle board cupboard doors caused by Mop slop when washing floors. Is there any way of sealing them and refinish them before laminating them.
Thanks,

If the doors are swollen due to moisture consider them buggered. Just cleaning them up and laminating over them will not be successful! The only thing to do is make new doors out of highly moisture resistant (HMR) material like MDF,HMR.
Yes start from scratch. And yes probably more dollars but if you were to laminate with Laminex the cost would be high anyway. I would choose a Lamiwood colour with edge tape to suit and that would be that

These days, most kitchen manufacturers use HMR board. If your doors predate HMR (mid '70s) it would be fair to say they have reached their use-by date. In cheaper kitchens the bottom edge of floor cupboard doors was left unedged as cockroaches seemed to lack appreciation for such detail. A new set of doors in an HMR product with edge banding will afford you a much more servicable result.

Many thanks to all who made comment. The answers are sensible but being on a pension and I have the Laminex $5 a 10 x 4 sheet and the $$$$ are not there to replace the doors as I don't have the equipment for boring the hinge holes and the facilities for cutting new sheets of the suggested material. I was thinking of imersing the edge in epoxy to bind them together and sanding then back, that I thought may give me a few more years and they may see me out.

Don, you will need to laminate both faces of the doors, otherwise the tension of the glue will cause the doors to cup. And cup they will.

Hi Rusty Nail, Thanks for the tip, I was going to spray the inside of the door With Auto Acrylic White and did one to see how it would take. I forgot to mention before that the doors were originally covered with Viny on both sides but the vinyl just peeled off with no stick at all . What causes the doors to cup, the glue drying or the Laminex shrinking or what?. These doors still have the adhesive very firmly attached and dry on both sides and the new adhesive keys into it very well likewise so does the auto laquer.
On looking closer at the botom of the doors the swelling on the outside is very minimal, where the problem is, there is a groove that has been cut along the centre which matches the groove in the top of the door that the plastic extrusion used for the handle fits across the top of the door, I dont know why they put the groove in the bottom as well?
Anyway it seems that the worst damage is in that groove and on reading another post with similar problems to mine , the advice given was to fill with plasterboard cement and sand down and prime and paint the edge. I have done a couple of the doors after running a saw along the groove and then blowing the rubbish out and then filling with plaster as recomended by the other post.
Many thanks for the advice,
Don ........
