Best adhesive LVT in Bathroom

I need some advice on adhesives for 5.5 M sq. LVT on a wooden floor in a bathroom
I have been told I need Uzin ke49 hybrid. The only size I can find is 14kg which will do 70sq M !!!
Does it come in smaller quantities, or is there an equally good substitute that does
Thanks in advance

 

Have a look on ebay, few sellers on there do a 6kg unit

 

Thanks Rugmumching

 

Fball F48 HT do a 5ltr

Thanks guys
