Rendering over previously painted walls

[donmaico]

I spoke to a surveyor who told mem all the houses down my road are of poor quality build(1930s) but i need to do something on mine as he also said the brickwork is poor quality with most of the pointing being rather soft and some of the bricks are spalling, so its either render or repointing .Not sure which would be the most cost effective either.I thought about having sandblasted first but then thought that might damage the brick face so i wondered whether there was some kind of steel mesh that could be attached to the walls and rendered over that, maybe something like this http://www.expandedmetalcompany.co.uk/metal_laths.html
To cap it all some of the tiles on my roof have spread sideways somewhat.

Any suggestions?

if its a choice between repointing and rendering i would repoint render often cracks leading to maintainance issues and other problems

must admit a builder told me that, but then i heard someone else say it depended on the sand used, ie plastering not building, and whether lime had been added or not

Id go with a breathable render maybe a normal sand cement lime render

or even something better like a monocouche render you can get a silicone based modern tho colour render
or breathable render pre bagged render noo worrys about mixes not beeing the same nice even mixed render.
with the added bonus of being able to use a base coat and Alkaline resistant mesh. for movement/cracking..

If you really love the look of the brickwork you can get brick effect render
or even stone work effect render..
or even how about External wall insulation (EWI)
bump up the U values nice and worm hard wearing self cleaning and get it renderd too
with a thin coat acrylic render...

ill add links

building sand has not the the strength of plastering sand or sharpsand because of the grain, also it will have impurities like silt which will cause shrinkage and all sorts of problems, but nonetheless even rendering which has been done with lime and plastering sand may need some kind of maintainance at some point just go out for a walk and take a look around you and tell me how many rendering jobs you can see that hasent got at least one crack in

 

[Skimmers]

a modern monocouche render self cleaning with a base coat and full mesh is less likely to crack move
even silicone based or not upvc beads ect
its one of the best choices out there.
its got a good turn around quick clean cheap U values modern renders are a lot better then most other

As far as rendering on to paintwork, I would use "rendaid" with mesh in it, it sticks to painted surfaces and once dry can then be rendered over.

If your house is of solid wall construction I would consider External wall insulation, with the rising cost of gas, now is the time to get it done and it will pay for itself in the long run.

Obviously if cost is a factor you can go the green deal route where you pay it off from the savings you save from using less gas, if your not too sure about the green deal just google it, there is loads of information out there.

If you can pay for it outright though that will be better as you wont be paying any interest and also you wont need to go to a green deal provider to get it done , so the price will come in cheaper, allow £70-£80 a square metre to have this done !

You did not mention green deal or the other options or rendaid, I can't see what your problem is ??? Next time I will say before hand I agree with skimmers before I add anythink, is that ok with you ? There's nothink wrong with backing up and adding extra to a previous comment if anythink it helps the OP to determine the route to go !
