House Construction

Just discovered that wall in our room on the ground floor has paint coming off and moisture on some parts. I know the best way to address this is to find and seal all crevices outside which unfortunately is covered by the neighbors wall.

Was planning to paint it with waterproofing paint. Is there a better way? Or is there a superior product you know of which I should use?

So now we know why the room is always moldy.

Check out Boysen aquaseal bro. Scrape off the affected part and then apply. Baka may seepage from neighbor's wall kaya nag ddamp yung wall mo. May problema din ako samin ng flaking wall sa loob pag nababasa yung exterior wall.

if the water is seeping in from the other side of your wall,
you will have to do something on the outside, to prevent the water from seeping into your concrete wall. painting it on the inside will only work for a short time.
it is also possible, that your neighbor has the same problem with his wall.
if so, you should join forces. install a cover between your two walls, to divert rain from both your wall exteriors so that rain water won't be able to fall in and seep thru both your walls.

Agree with you Doc, probably they are firewall to firewall. They need to put a capping on top of the exterior wall to prevent water seepage.

Thanks, na solve ba ng Aquaseal?

Edit: pang bare substrate lang pala ito

I saw this rain or shine hydrolock, unfortunately wala ata silang website kaya I cannot find any info on the preparation required. Don't even know if it can be painted over paint. Anyone familiar with this?

I'd check the flashing between the the two firewalls in the roof since that is the source of the leak. The rain or shine hydrolock should work since the leak is negative pressure.

Instructions for paint are usually printed on the bucket. You will most likely have to peel off the existing paint

Thanks, I watched 2 yt vids on this and they both recommend stripping the old paint. One was recommending his products (buildrite) while the other was just trying to share and says that any cementitious paint will do the trick.

But they both agreed that this is a solution for situations like mine where houses are built side by side therefore difficult to address externally. And they mentioned ideal for basement, which means this is really effective if done correctly.
