Hi All

ex council house outside store roof 100mm thick concrete area about
4m x 3 metres

has rasied front and sides (a lip about 25mm high)

Never been felted

Looking at the fibrous paints or other low cost solution

any recommendations

Regards


having atempted all of the suggestions in this thread over the past thirty
years, I have found only one solution and that is to use a product called
'cromapol'

I've done a few concrete rooves with this and had no problems at all, it's
expensive, because it works.

Don't bother with anything available from B&Q et al, they also have
expensive sealants, but none of them work on cracked concrete

It's available in black, white and grey
