Temporary glue for floating engineered wood floor?

[8ball]

I have had loads of fun and games laying a floating engineered wood floor and have come to lay the last few boards, the boards will be fitted over central heating pipes which sit encased in concrete channels.

My question is what temporary glue could I use for the wood flooring so that I could get to the pipes underneath in the future if I had a leaky pipe? I was thinking about dabs of hot glue in the tongue and groove or I had another recommendation of using latex glue ( Copydex Latex Adhesive).

 

I'd rather use hot glue because I already have some ,

 

Cheers for any info dudes?
