thanks for replies,
asphalt is flooring grade, well cured
there is not enough height to do the sand/cement option

can anyone give more detail on spf? is this BAL spf? or are there any other products I can use, (I assume the Dunlop Set Fast Plus is not spf?)

thanks again

Dont use bal ...I've had nothing but trouble from bal flexi one to the spf .. and now bal say every excuse under the book ..yet 15 years ago I had no problem in other rooms ... put bluntly ..bal = rubbish
