Whats the best method of sealing cut edges of worktop under sink and such. Was planning on running a fat bead of silcone sealent on the edges and then smoothing it down to cover. Is this ok or is there a better method?
Thanks
2 coats of polyurethane varnish would be far preferable and easier.

Suggest you try the following:
In a small glass jar, take some silicone sealant and make a liquid/paste with the minimum of while spirit so that it just flows like engine oil.
Paint/dab this thinly onto the freshly cut exposed ends of the formica work top so that it soaks in. Repeat when dried until no more soaks in and then let dry thoroughly. Give it time!
No naked flames, well ventilated room etc.!! Protect hands/eyes/face etc. as usual.
This should do the trick Do this with any exposed ends/corners where there is likely to be water/condensation contact. Also before adding the metal end/dividing strips.
FWIW RDD

a good coat of a Acrylic primer or two if you prefer is more than adequate
I have used PVA in the past... is this ok?

The reason I suggested the silicone/solvent is that when there is likely to be an excess of moisture:
A) water vapour can penetrate PA and acrylic water based emulsions especially in hot humid micro-climates.
B) PVA and water based acrylics don't necessarily penetrate into the "grain" of the board.
The while spirit carries the silicone into the grain and there it should polymerise upon drying giving you a deep impenetrable layer.
The use of solvents is taboo in this environmentally conscious climate. But a small amount won't hurt.
BTW I have used this technique to seal old porous iron castings .
No guarantee given of course but IMHO worth a try. RDD
