Hi all!

Ive been recently rep[ainting the house from to bottom front and back and im abouit to finish with the back yard wall. However it appears to be not very happy! Ive tried to research a remedy but end up with too many questions once again! So here I am! Hope you can solve this!

Basically what is it and can I stop it from happening again once its been painted?


Its just a dividing yard wall between terraced houses. Tried to attach as many pics as possible but if you need more please let me know! :-)

Rising damp pushing the masonry paint off? A garden wall may not have any damp course. Just a first guess...

whats hapning on the other side of the wall, is it well pointed or painted? your paint looks like oil paint an it should havebeen masonry wash. when the bricksare dry brush off the crystals but it might be a thankless task.

What is it .. who knows. This https://www.crowntrade.co.uk/product/in ... ng-sealer/ may help but how well it will work over the existing paint when the paint decides to fail - if it does - I have not got a clue. Read carefully the Product Data Sheet from the page above.

Plus yesterday i notcied paint peeling in the kitchen (which is the same walls as the possible rising damp on and as I went to peel it half the kitchen ended up coming off! (Paint wise)! Ahhhhh!!!

Again, what is on the other side of the wall?
Is it retaining soil?
Is it painted?

Rising damp isn't necessarily a problem as long as the damp is ventilated at a low level - under a suspended floor for example. It certainly isn't a problem on a garden wall as long as it can dry out ie. not covered with a waterproof paint. The paint should be breathable and no modern masonry paints are as breathable as clay or lime based washes - it just depends how much you want to revert to the way the building worked originally.

Hi Barry, Thanks for your quick responces!

Ive managed to snap some secret pics of the other side of the wall! (Sorry they are not the best) Doesnt seem as bad as I thought but I know for a fact it isnt looked after!

Its not painted though and ive noticed in the past lots of large weeds/plants attempting to grow there! So big ive pulled them out myself by sticking my hand over the wall.

As for my kitchen which also has a similar problem at the bottom of the walls (like the garden wall) here is some pics of that. (Inside and out)

The interior kitchen pics is where the paint was peeling off. (I took it all off yesterday) As you can see its only near the door and then left hand side of the rear window.

Do agree that the house does need to breath, just want it to look nice too!

Thanks OchAye, ive been looking at this stuff as well. Was going to slap some on alkl over the garden wall and then I noticed my kitchen wall too. But as the house needs to breath wasnt too sure wether to put some on or not. (The house that is) Ive placed lots of pics of everything (walls kitchen etc) in another reply on this page just in case you want to see! :-)

The alcali resisting primer is meant to seal salts/efflorescence your kitchen appears to have a different problem. Perhaps dampness, perhaps the walls painted wrongly and the paint peeled off.

So confusing isnt it! \Ive been trying to find a seveyor who gives free quotes but the nearest i found was in the oxford area! Im in Liverpool!

Hopefully the alkili paint stuf will sort the wall at least and im going to leave the kitchen to dry out for a while, then put on some BIN primer before finally some kitchen eggshell paint!

Then knowing my luck the house will fall down! Ha ha!

Cheers Wes56, Ive attached some pics of the wall on the other side to try and show everyone. Hope that helps! The paint I used was a water based Masonary paint, think it may end up being a never ending job!!

The other side of the wall shows similar problems to your lower side which is like rising damp pushing out efflorescence. You need to let the wall dry as much as possible, therefore I am not sure if the plastic grass you put on the concrete helps or hinders the drying out bit.
