Wall Efflorescence

Question

A little portion of my wall had Efflorescence. I found the water was coming through the roof tiles which I got fixed. So I would like to know how I can fix the affected area now. Just cleaning and filling the damage area and repainting will do the job?

Michael · Answer

Pressurized water: Applying pressurized water can dissolve efflorescence quickly.

Diluted vinegar: Diluted white vinegar can be used on efflorescence.

Brushing: A strong brush can be used to remove efflorescence

Jonathan · Answer

HI I would recommend sealing the area with undercoat or a primer sealer before applying your top coat.

Daniel · Answer

I think is best to change the roof tiles where it’s leaks and cut the affected parts of the roof and replace then paint

Anthony · Answer

Once gypsum type plaster has water ingress for a period, unfortunately the only correct way is to strip back and start again.

Kash · Answer

Its hard to advise when we cannot see it but normally if there has been a leak, allow it to dry (by that i mean a few weeks) then apply zinnsser stain block and then paint over with a damp proof paint.
