If you see bubbling in your plaster interior walls, the solution can be found in the original materials used to build their old homes. Here's what you need to know about the cause of the damage: Traditional Tuckpointing Prevented Water Damage The traditional materials used to build historic brick homes have held up over time due in part to the way they allow moisture to move safely through them.
If not the whole wall, strip to at least five feet above ground level. Tuckpoint the joints, removing the cement mortar and replacing with traditional lime mortar.
Consult a masonry contractor with experience and expertise in traditional methods and materials. Repaint with a limewash tinted to match the original paint color. An advantage of limewash is that it is highly breathable and will draw out the salt that may enter the wall in the future.
Remove any gypsum based materials on the interior wall and replace with traditional lime plaster that is less sensitive to moisture. Cover with a top coat of casein paint — milk paint mixed with 1 percent boiled linseed oil.
Check the basement wall. Chip off any waterproofing material to let the brick dry out on the inside. Hey all, Sorry to bump this item back up the forum list but I really wanted to say thanks again for all the advice and give some feedback for anyone else in the future who might be experiencing the same issues I was.
I slowed my mixer right down, and gave my coats a little bit more thickness which seemed to work. Also I let the plaster go off a bit more than I ever had before and just worked is smooth with a bit of extra elbow grease!! Finally, and most significantly I think, I really restrained myself with the amount of water I was putting on the walls during the wet trowels and that's made a world of difference.
I've attached some picture below of my latest attempt after 24hours drying. I know I'll never be a pro, but not a bad afternoon's work for an accountant!! I think that once you have laid it on you are going back on it to quick.. As for the mixing it, we mix our skim bag at a time in large gorrilla buckets and we only keep it on slow speed till there's enough stuff in the bucket to stop it splashin' every where, then quick as you like.
We leave it after it's mixed for a minute or two before using it. Try not to put any water on the wall ,only on your trowel. Joined: 3 Sep Country:.

Replies: 4 Views: JohnL24 1 Apr This is the compound I used to make the repair. And here is a before and after image of the job. You can clearly see the bubbles. They appeared within seconds of applying the top coat. The other image is of the job about an hour afterwards. Attached Thumbnails. I am not a plasterer but it is a common problem. Search this forums for "Bubbles" it has been discussed many times before.
Basically sand and light skim to fill, light sand, jobs done. Regards Dave. I thought the top coat would give a perfect finish. A chemical reaction goes on with blistering the result. The bubbles appeared in the top coat so quickly it was as though some similar chemical reaction is happening.
Maybe the multipurpose joint compound has something to do with it. I don't know but I won't use this stuff.
