Which levelling compound on damp porch floor?

[andyfr]

I had originally thought of using self levelling compound over the tiles in our porch, but they were so far out I decided to take them up yesterday. The base is a bit damp so I need to find a self levelling compound suitable for using in this situation. The porch is 1.5m x 2.5m and was built in the 80s.

Thanks

Ardit NA and F-Ball 1200 can both be laid over damp subfloors as they are moisture tolerant, however, what do you plan to fit over the top?

Thank you, I'll see if I can get some. I was thinking of Karndean rigid core flooring as I have enough to do that area, but may get ceramic or porcelain floor tiles if that would be a better option.

If it’s damp I’d put na / 1200 pro then go with a liquid Dpm like ardex DPM1c or fball F77
