Dear Mr DIY Guy you need more experience and expertise before answering questions like this.
It is widely accepted practice in the UK to use flexible adhesive to bond solid wood flooring to solid substrates like Concrete/screeds.
the underlay that you used is useless when fixing solid wood flooring and it is against best practice to float a solid wood floor as this leads to failure in the bond and eventual separation of the flooring. This may of course take some time but in the end it will happen.
it is a good idea to keep the ambient temerature stable but the use of underlay will nothelp this in any significant way. Wood itself is a good insulator and cold wil not be felt coming up from the substrate.
if you have installed a solid wood floor floating on underlay why don't you show us a picture now and then again in a year or two. should be interesting.
Anyway Rowntree to answer your question:
Sika T55 is not a very smart solution. Although it is not mentioned when you buy this product I would suggestbthat you take a look at the following URL which provides interesting reading on Sika T55. You will see that it is not a particularly safe product to have your face over for a few hours and I can't believe that this is sold to the public without any warning.
With regard to your other answer where you have been advised that Sika is the 'next generation of flexible adhesives' this is incorrect. Sika is a polyurethane product as is Mapei 990K and this technology is definately not new. The latest generation of wood flooring adhesives is MS based products which unlike Sika and similar do not contain hazardous substances. I am surprised that you are being advised to use Plyurethane products which carry warning labels on the containers are difficult to use and generally leave you with a difficult clean up job.
