Sealing a worktop to make it heat resistant

[diyAlex]

Just about to install a bosch electric hob, and the instructions say "seal cut surfaces to make them heat-resistant". This is in relation to a square being cut out of the middle of the worktop.

What can I use to seal the exposed chipboard of the worktop? Is there some sort of paint type stuff that can be applied??

It shouldn't really be nessesary but you could use self adhesive metal tape.

Cut outs, especially sink, are often sealed using silicone smeared all over the exposed chipboard. Silicone is fairly heat resistant by itself.
