Water damaged brickwork crumbling behind plaster - pro job?

last year

Hi all,

we had a leaky roof that has since been repaired.

It left some bad water damage in our bathroom on the wall/ceiling corner.

After stripping it back the brickwork behind the plaster seems to be crumbling fairly deeply.

I was planning on just skimming over with plaster repair but the deeper holes seem like they need filling and the corner mesh cutting back.

Is this a pro joob or doable diy - and if so, how?

pics attached. thanks!

Repairing water damaged brickwork behind plaster can be a challenging task, and it's usually best to seek the help of a professional if you're not experienced in this type of work. However, if you're confident in your DIY skills and are willing to take on the task, here are some general steps to follow:
1. Remove any loose plaster from the affected area to assess the extent of the damage to the brickwork. Use a hammer and chisel to carefully chip away any loose or crumbling plaster, being careful not to damage the underlying brickwork.
2. Once you've exposed the damaged brickwork, use a stiff-bristled brush or wire brush to remove any loose or flaking mortar, dirt, or debris from the surface of the bricks.
3. If the damage is limited to a small area, you may be able to repair the brickwork by mixing up a small batch of mortar and carefully applying it to the damaged area with a trowel. Make sure to use mortar that is appropriate for the type of bricks you have and to mix it to the correct consistency.
4. If the damage is more extensive, you may need to replace some of the damaged bricks. Carefully remove the damaged bricks, being careful not to damage the surrounding bricks or mortar, and replace them with new bricks that match the size, color, and texture of the existing bricks. Use appropriate mortar to secure the new bricks in place.
5. Once the brickwork has been repaired or replaced, allow the mortar to dry fully before applying a new layer of plaster to the surface. You may want to consider using a damp-proof membrane or sealant on the brickwork to help prevent future water damage.
If the damage is extensive or if you're unsure of your DIY skills, it's always best to consult with a professional bricklayer or building contractor and get it done properly.

Those are wise words Karen! am so glad it worked out for you. Love to see a photo, what colour or shade did you choose? Jools, The bitumen is a right pig, best way we found is to make it cold, so it becomes brittle, then you can scrape /chip it off. We used a window scraper, coarse wire wool and various sandpaper. We left the window open on a cold night, turned heating off in there, and you could try a cooler fan on it. Putting ice bags on it didn't work as well as we hoped. we used a round sander, but it can cause swirls, it's really awkward ! To be honest a few dips and scratches on an old floor are okay in the end, don't be too afraid of it, they are only pieces of wood stuck down on the floor, not bone china, as long as you try not to break them, or set fire to them, otherwise you can't possibly do more damage than I did, and they recovered!

it says J J 1909, my house was built in 1984 so it must have come from the old man's parents' house? His surname was Jacquier. i have been trying to brush the cast iron plate with a toothbrush, a lot of soot has come off but there's a lot of creosote on there. i'm going to see if there's something a bit more efficient than my son's old toothbrush!! also, because of the bicarbonate i can't get in there without getting my jeans dirty! really pleased with it though! might do another wash and see if i can get any more off!

Wrong render colour?!

I’m glad I found this post. Feeling like I could cry. Just had front and back of the house rendered in Atlas ‘off white’ (renderer said white was too stark) so went with off white…The colour looks like it has a tinge of pink/lilac/grey to it 😭 😭😭 Feeling very depressed as it was a big job. I was advised by the renderers to repaint using silicone paint.

@Pavan123... just to update you. I've spent the best part of a week (not full days of course - just few hours here and there when I can!) cleaning the wall up. It was COVERED in old render and dust - thick chunks of it in most places. The mortar pointing was like sand as well. So I got a water spray and a putty knife (or a flat edge wallpaper scraper would do) with a dust mask and goggles on and just scraped off what I could whilst spraying water over it to keep the dust to a minimum. Then i manually scraped out the top of the pointing then scrubbed it all with a stiff brush and warm soapy water (I should have used sugar soap) then rinsed it off. Now it's ready to re-point and I will give it a final clean/wipe down after the pointing sets as there are only some parts with the white dust on. I could get brick acid on it but I kind of like the old look so don't want them to be TOO clean and new looking! LOL. My wall is a bit of a mess though to be fair. Will post a pic up later. Whoever built it must have used any old broken bricks lying around as there are chunks missing out of some, some rows are all split bricks etc. Might remove a few and put full ones back we saved.
