hi
my brother and i done a concrete base for my shed which as got got rising damp..i,ve tested with plastic/tape on the floor plus other stuff in there was damp..my wooden sheds on a row of breeze blocks and floors not smooth so needed some help how to sort the damp out..been lookin on net and come across this Google "wickes.co.uk/liquid-damp-proof-membrane/invt/241217/" just lookin for the cheap way to sort it,if only temp for this year..so would i beable to use this then smooth floor off and use liquid damp proof again...?

to level the floor,Mix a pva solution 50/50 and pour it on and brush it in,when the pva is tacky mix a self level compound and spread it on the floor.
The pva is a waterproof bonding sealant so it should do the job.

the floor from top to bottom is about 2 inches out.pritty bad job..did put pva on it a while ago but think it was 80/20.water/pva

What's this pva solution???

seeing as its nearly 2"out of level you can lay a polythene membrane down and then lay a 50-75mm screed on top
