Roger from Maidstone is having access problems and has asked that this question be posted on his behalf......



The problem I have is this: I need to screed the floor of a small sun room (3m x3m) that I am building on the back of my house and will be screeding on top of the existing external ground slab and will need to waterproof it in some way, almost, in a sense, tank it up prior to screeding. Is Synthaprufe the best thing for this and how would I prepare the Synthaprufe to accept the screed. Thank you very much.

make sure the concrete is dry and dust free,then apply the synthaprufe with a round heavy bristled brush,dont paint it like paint just use the brush to get it on
you need 3 coats which at this time of year will take 36 hours per coat to dry out

do not and i repeat, do not get this stuff on the curtains ,your hands ,the carpets,your car ,or anywhere else except the area to be screeded

it is mega difficult to get out ,so be careful

cheers LLL
