http://www.dritac.com/product/dritac-5900-megabond/ Just had a rep in the shop I fit for telling me this is the new revolution Apparently you can stick straight onto damp floors (>95%)
They use these types of adhesives in the US all there data sheets state what RH level you can use them up to Karndean US have an adhesive called drytack you put down with a roller
I have massive concerns on the 5900, have anyone else read the spec sheet, it various a fair amount from floorcovering to RH.
Don’t get me wrong, looks a great adhesive and feedback has also stated the same, also the fella behind it is a nice chap.
