Seal laminate board - with what?

[BiFuel]

I'm going to cut a hole for an induction hob in a laminate board (lg collection) that we bought. It says to seal the sawn edges with either a moisture barrier for bathrooms or with clear varnish. Does anyone have any tips regarding this? It should probably be something that withstands heat fairly well, right?

Some kind of paint? Våtrumssilikon, does it withstand heat?

 

[BiFuel]

Common carpentry paint that we've used for the kitchen cabinets?

Shellack is fine.

Unfortunately, I don't have any shellac. Doesn't regular paint work? It covers well.

Bought a mini jar of hobby paint (water-based). It might do.

If you take your hobbylack, an induction hob does not get hot.

I usually tape where the hole is to be made, then I leave the tape on the top side until I've sealed the cut with silicone. I do the same for the sink hole. As others have said, the stove shouldn't become significantly warm on the underside/edges, so I think exactly what you use is irrelevant as long as it keeps moisture/water away from the core of the board. The point is to make it tight and avoid problems.

Yes, I'll probably try with the varnish. Feels like it would require a lot of silicone to cover the saw cuts of 56+56+49+49 cm and 3 cm high Messy!

Polyurethane paint or polyurethane varnish.

Hmm, not sure if our cabinet color for the kitchen is polyurethane... have to check.

 

[BiFuel]

Yes, the paint we had at home (Superfinish V40) is polyurethane paint. That will be the one then, I'm used to working with it.

Nice, it will be perfect. Polyurethane paint is more moisture and chemical resistant and withstands higher temperatures than regular paint.

Great! Then I have time to get it painted before the electrician comes to hook things up on Wednesday! I noticed that the paint is very water-repellent when I spilled water on a newly painted (but dry) cabinet door. It ran off like water off a duck's back!
